Software Engineering covers the definition of processes, techniques and models suitable for its
environment to guarantee quality of results. An important design artifact in any software
development project is the Software Architecture. Software Architecture’s important part is the
set of architectural design rules. A primary goal of the architecture is to capture the
architecture design decisions. An important part of these design decisions consists of
architectural design rules In an MDA (Model-Driven Architecture) context, the design of the
system architecture is captured in the models of the system. MDA is known to be layered
approach for modeling the architectural design rules and uses design patterns to improve the
quality of software system. And to include the security to the software system, security patterns
are introduced that offer security at the architectural level. More over, agile software
development methods are used to build secure systems. There are different methods defined in
agile development as extreme programming (XP), scrum, feature driven development (FDD),
test driven development (TDD), etc. Agile processing is includes the phases as agile analysis,
agile design and agile testing. These phases are defined in layers of MDA to provide security at
the modeling level which ensures that security at the system architecture stage will improve the
requirements for that system. Agile modeled Layered Security Architectures increase the
dependability of the architecture in terms of privacy requirements. We validate this with a case
study of dependability of privacy of Web Services Security Architectures, which helps for secure
service oriented security architecture. In this paper the major part is given to model
architectural design rules using MDA so that architects and developers are responsible to
automatic enforcement on the detailed design and easy to understand and use by both of them.
This MDA approach is implemented in use of Agile strategy in three different phases covering
three different layers to provide security to the system. With this procedure a premise
conclusion has been given that with the system security the requirements for that system are
improved. This paper summarizes that security is essential for every system at initial stage and
upon introduction of security at middle stage must lead to the change in the system i.e., an
improvement to system requirements.
A UML Profile for Security and Code Generation IJECEIAES
Recently, many research studies have suggested the integration of safety engineering at an early stage of modeling and system development using Model-Driven Architecture (MDA). This concept consists in deploying the UML (Unified Modeling Language) standard as aprincipal metamodel for the abstractions of different systems. To our knowledge, most of this work has focused on integrating security requirements after the implementation phase without taking them into account when designing systems. In this work, we focused our efforts on non-functional aspects such as the business logic layer, data flow monitoring, and high-quality service delivery. Practically, we have proposed a new UML profile for security integration and code generation for the Java platform. Therefore, the security properties will be described by a UML profile and the OCL language to verify the requirements of confidentiality, authorization, availability, data integrity, and data encryption. Finally, the source code such as the application security configuration, the method signatures and their bodies, the persistent entities and the security controllers generated from sequence diagram of system’s internal behavior after its extension with this profile and applying a set of transformations.

Software Reliability and Quality Assurance Challenges in Cyber Physical Syste...CSCJournals
Software Reliability is the probability of failure-free software operation for a specified period of time in a specified environment. Cyber threats on software security have been prevailing and have increased exponentially, posing a major challenge on software reliability in the cyber physical systems (CPS) environment. Applying patches after the software has been developed is outdated and a major security flaw. However, this has posed a major software reliability challenge as threat actors are exploiting unpatched and insecure software configuration vulnerabilities that are not identified at the design phase. This paper aims to investigate the SDLC approach to software reliability and quality assurance challenges in CPS security. To demonstrate the applicability of our work, we review existing security requirements engineering concepts and methodologies such as TROPOS, I*, KAOS, Tropos and Secure Tropos to determine their relevance in software security. We consider how the methodologies and function points are used to implement constraints to improve software reliability. Finally, the function points concepts are implemented into the CPS security components. The results show that software security threats in CPS can be addressed by integrating the SRE approach and function point analysis in the development to improve software reliability.
A reliability estimation framework for OO design complexity perspective has been developed inthis paper. The proposed framework correlates the object oriented design constructs with complexity and also correlates complexity with reliability. No such framework has been available in the literature that estimates software reliability of OO design by taking complexity into consideration. The framework bridges the gap between object oriented design constructs, complexity and reliability. Framework measures and minimizes the complexity of software design at the early stage of software development life cycle leading to a reliable end product. Reliability and complexity estimation models have been proposed by following the proposed framework. Complexity estimation model has been developed which takes OO design constructs into consideration and proposed reliability estimation models take complexity in consideration for estimating reliability of OO design.
Design patterns are general reusable solutions to common problems in software design. The Gang of Four patterns are 23 classic design patterns divided into creational, structural, and behavioral categories. Design principles provide guidelines for building software, such as using registries as a single source of truth, adopting a mobile-first design strategy, and ensuring privacy and security by design. Well-defined registries should be self-maintainable, have non-repudiable data, extensible schemas, and support open APIs. A cloud-first strategy employs patterns like external configuration, cache-aside, and federated identity. A minimalistic approach focuses on auto-scaling, decoupled microservices, and separating reads from writes.
The document discusses various topics related to software engineering including:
1) How early days of software development have affected modern practices.
2) Definitions of software engineering from different sources.
3) The stages of software design including problem analysis, solution identification, and abstraction description.

A study on security responsibilities and adoption in cloudeSAT Journals
Abstract Cloud computing is one of the popular enterprise models where computing resources are made available on-demand to the user as needed. Due to this increasing demand for more clouds there is an ever growing threat of security becoming a major issue. cloud computing is a construct that allows you to access applications that actually reside at a location other than your computer or other Internet-connected device, most often, this will be a distant data center. In a simple, topological sense, a cloud computing solution is made up of several elements: clients, the datacenter, and distributed servers. Each element has a purpose and plays a specific role in delivering a functional cloud based application, the increased degree of connectivity and the increasing amount of data has led many providers and in particular data centers to employ larger infrastructures with dynamic load and access balancing. So this paper shall look at ways in which security responsibilities and Cloud Adoption Keywords: Cloud Computing, Service models, Cloud Security, Secure Cloud Adoption,

VTrace-A Tool for Visualizing Traceability Links among Software Artefacts for...journalBEEI
Traceability Management plays a key role in tracing the life of a requirement through all the specifications produced during the development phase of a software project. A lack of traceability information not only hinders the understanding of the system but also will prove to be a bottleneck in the future maintenance of the system. Projects that maintain traceability information during the development stages somehow fail to upgrade their artefacts or maintain traceability among the different versions of the artefacts that are produced during the maintenance phase. As a result the software artefacts lose the trustworthiness and engineers mostly work from the source code for impact analysis. The goal of our research is on understanding the impact of visualizing traceability links on change management tasks for an evolving system. As part of our research we have implemented a Traceability Visualization Tool-VTrace that manages software artefacts and also enables the visualization of traceability links. The results of our controlled experiment show that subjects who used the tool were more accurate and faster on change management tasks than subjects that didn’t use the tool.

A Proposed Security Model for Web Enabled Business Process Management SystemCSCJournals
Many organizations in industry and civilian government start deploying Business Process Management systems (BPMS) and technology in their IT applications. This could lead to a dramatic operational efficiency improvement on their business and administrative environments. With these atmospheres, the security issue is becoming a much more important challenge in the BPMS literature. The Role-Based Access Control (RBAC) model has been accepted as a promise security model solution and standard. RBAC is able to accomplish the central administration of an organizational specific security policy. It is also able to meet the secure processing needs of many commercial and civilian government organizations. In spite of these facts, RBAC model is not reliable when applying to the BPMS without further modifications and extensions. RBAC is modified to fit with Service oriented (SRBAC), but still not reliable enough to handle BPMS. Authors of that research proposed a security model based on SRBAC model to be more reliable when using with BPMS. Authors of that research named that proposed security model as Improved Role Based Access Control (IRBAC). The IRBAC model is directly applicable to the BPMS. Authors defined a graphical representation and technical implementation of the IRBAC model. This IRBAC model is tested using simple case study. The test compares between the IRBAC model and SRBAC model where IRBAC is implemented in two cases (IRBAC with caching and IRBAC with no caching). The test results show the validity and performability of the IRBAC model.
Service oriented configuration management of software architectureIJNSA Journal
Software configuration management (SCM) is an important activity in the software engineering life cycle. SCM by control of the evolution process of products leads to constancy and stability in software systems. Nowadays, use of software configuration management is essential during the process of software development as rules to control and manage the evolution of software systems. SCM effects different levels of abstraction included the architectural level. Configuration of software architecture causes improvement in the configuration of the lower abstraction levels. CM of software architecture is more significant in large scale software with longevity of life cycle. Traditional SCM approaches, at the architectural level, do not provided the necessary support to software configuration management, so systems that use these approaches are faced with problems. These problems arise because of the lack of a serious constant and repeated changes in the software process. To overcome this it is necessary to create an infrastructure. Hence, a service oriented approach for configuration management is presented in this paper. In this approach, the activities of configuration management are conducted from a service oriented viewpoint. This approach was also used to try and control the evolution and number of versions of different software systems in order to identify, organize and control change and reforms during the production process. This approach can compose services and create composite services for new undefined activities of configuration.
IRJET- Privacy Preserving and Proficient Identity Search Techniques for C...IRJET Journal
This document presents a privacy preserving and efficient identity search technique for cloud data security. It proposes a scheme using visual-encryption techniques to overcome issues with untrusted cloud storage. The existing methodology uses data signing algorithms but has limitations as the private key depends on the security of one computer. The proposed system uses visual-cryptographic encryption, which scrambles data using an algorithm requiring a key to decrypt. It involves users uploading encrypted files, administrators approving requests to view files through live video verification, and decryption using the appropriate key. The scheme aims to securely store large volumes of data while allowing identity verification for file access on the cloud.
The data design action translates data objects into data structures at the software component level.
Data Design is the first and most important design activity. Here the main issue is to select the appropriate data structure i.e. the data design focuses on the definition of data structures.
Data design is a process of gradual refinement, from the coarse "What data does your application require?" to the precise data structures and processes that provide it. With a good data design, your application's data access is fast, easily maintained, and can gracefully accept future data enhancements.
This lecture document provides an overview of comparative development methodologies. It discusses frameworks like Multiview, Strategic Options Development and Analysis (SODA), the Capability Maturity Model (CMM), and Euromethod.

Additionally, it outlines the evolution of methodologies from the pre-methodology era to early methodologies to more modern approaches.
This document discusses software processes and models. It covers the following key points:
1. Software processes involve activities like specification, design, implementation, validation and evolution to develop software systems. Common process models include waterfall, incremental development and reuse-oriented development.
2. Processes need to cope with inevitable changes. This can involve prototyping to avoid rework or using incremental development and delivery to more easily accommodate changes.
3. The Rational Unified Process is a modern process model with phases for inception, elaboration, construction and transition. It advocates iterative development and managing requirements and quality.
This document provides an overview of software architecture. It defines software architecture as the set of structures needed to reason about a computing system, including elements, relations among them, and their properties.

This document provides an overview of the Software Engineering 2 course, including its aims, objectives, course contents, and recommended textbooks. The course aims to provide knowledge of techniques for estimating, designing, building, and ensuring quality in software projects. The objectives cover understanding software metrics, estimating project costs and schedules, quality assurance attributes and standards, and software analysis and design techniques. The course content includes topics like software metrics, estimation models, quality assurance, and object-oriented analysis and design. The document also summarizes several software engineering process models and risk management approaches.
This document summarizes key points from a lecture on aspect-oriented software development:
1. Aspect-oriented development supports separating concerns by representing cross-cutting concerns as aspects. This allows individual concerns to be understood, reused, and modified without changing other parts of the program.
2. Viewpoint-oriented requirements engineering focuses on stakeholder concerns and identifies cross-cutting concerns that affect all viewpoints.
3. Designing aspect-oriented systems involves identifying core functionality, aspects, and where aspects should be composed with the core. Testing aspect-oriented programs poses challenges around program inspection and deriving tests.

3) Sociotechnical systems have emergent properties that depend on the interactions between system components and cannot be understood by examining the components individually.
This document provides an introduction to software architecture. It discusses what software architecture is, popular architecture styles, quality attributes of a system, and architecture design guidelines. The key points are:
- Software architecture is the high-level design of a system that guides its construction and development. It defines the relationship between major structural elements.
- Popular architecture styles include layered, pipes and filters, and event-based. Each style has advantages and disadvantages for certain quality attributes.
- Quality attributes include implementation attributes like maintainability, runtime attributes like performance and availability, and business attributes like time to market. There are often tradeoffs between attributes.
- Architecture design guidelines include thinking about requirements before design, using abstraction, considering non-
Security has always been a great concern for all software systems due to the increased incursion of the wireless devices in recent years. Generally software engineering processes tries to compel the security measures during the various design phases which results into an inefficient measure. So this calls for a new process of software engineering in which we would try to give a proper framework for integrating the security requirements with the SDLC, and in this requirement engineers must discover all the security requirements related to a particular system, so security requirement could be analyzed and simultaneously prioritized in one go. In this paper we will present a new technique for prioritizing these requirement based on the risk measurement techniques. The true security requirements should be easily identified as early as possible so that these could be systematically analyzed and then every architecture team can choose the most appropriate mechanism to implement them.

Hence, a service oriented approach for configuration management is presented in this paper. In this approach, the activities of configuration management are conducted from a service oriented viewpoint. This approach was also used to try and control the evolution and number of versions of different software systems in order to identify, organize and control change and reforms during the production process. This approach can compose services and create composite services for new undefined activities of configuration.
IRJET- Privacy Preserving and Proficient Identity Search Techniques for C...IRJET Journal
This document presents a privacy preserving and efficient identity search technique for cloud data security. It proposes a scheme using visual-encryption techniques to overcome issues with untrusted cloud storage. The existing methodology uses data signing algorithms but has limitations as the private key depends on the security of one computer. The proposed system uses visual-cryptographic encryption, which scrambles data using an algorithm requiring a key to decrypt. It involves users uploading encrypted files, administrators approving requests to view files through live video verification, and decryption using the appropriate key. The scheme aims to securely store large volumes of data while allowing identity verification for file access on the cloud.
The data design action translates data objects into data structures at the software component level.
Data Design is the first and most important design activity. Here the main issue is to select the appropriate data structure i.e. the data design focuses on the definition of data structures.
Data design is a process of gradual refinement, from the coarse "What data does your application require?" to the precise data structures and processes that provide it. With a good data design, your application's data access is fast, easily maintained, and can gracefully accept future data enhancements.

This document provides an introduction to software architecture. It discusses what software architecture is, popular architecture styles, quality attributes of a system, and architecture design guidelines. The key points are:
- Software architecture is the high-level design of a system that guides its construction and development. It defines the relationship between major structural elements.
- Popular architecture styles include layered, pipes and filters, and event-based. Each style has advantages and disadvantages for certain quality attributes.
- Quality attributes include implementation attributes like maintainability, runtime attributes like performance and availability, and business attributes like time to market. There are often tradeoffs between attributes.
- Architecture design guidelines include thinking about requirements before design, using abstraction, considering non-
Security has always been a great concern for all software systems due to the increased incursion of the wireless devices in recent years. Generally software engineering processes tries to compel the security measures during the various design phases which results into an inefficient measure. So this calls for a new process of software engineering in which we would try to give a proper framework for integrating the security requirements with the SDLC, and in this requirement engineers must discover all the security requirements related to a particular system, so security requirement could be analyzed and simultaneously prioritized in one go. In this paper we will present a new technique for prioritizing these requirement based on the risk measurement techniques. The true security requirements should be easily identified as early as possible so that these could be systematically analyzed and then every architecture team can choose the most appropriate mechanism to implement them.
The document provides definitions and explanations of key software engineering concepts. It summarizes stakeholders as anyone who directly or indirectly benefits from a system. Prototyping draws criticism for prioritizing quick prototypes over quality. Incremental development delivers software in pieces that build on prior deliveries, while evolutionary development iteratively produces more complete versions. Formal methods are not widely used due to extended timelines, complex mathematics, and incompatibility with other tools. Risk analysis identifies possible losses in development. Information systems link to business objectives by improving processes and maintaining competitive advantages. Process improvement involves measurement, analysis, change identification. Requirements elicitation uses techniques like interviews and prototyping. Architecture design represents effectiveness and reduces risks. Modular design improves

This document describes a software design approach for developing secure data management applications using model-driven development. It involves modeling an application's conceptual model, security model, and graphical user interface model. A model transformation lifts security policies from the security model to the GUI model. The models are validated for correctness before code generation. The approach was implemented in a tool called Sculpture, which was used to develop three secure web applications: a volunteer management app, electronic health record app, and meal service management app. The approach aims to improve on previous work by providing more expressive modeling languages, validation of models, and automated generation of secure multi-tier applications.

DESQA a Software Quality Assurance FrameworkIJERA Editor
In current software development lifecycles of heterogeneous environments, the pitfalls businesses have to face are that software defect tracking, measurements and quality assurance do not start early enough in the development process. In fact the cost of fixing a defect in a production environment is much higher than in the initial phases of the Software Development Life Cycle (SDLC) which is particularly true for Service Oriented Architecture (SOA). Thus the aim of this study is to develop a new framework for defect tracking and detection and quality estimation for early stages particularly for the design stage of the SDLC. Part of the objectives of this work is to conceptualize, borrow and customize from known frameworks, such as object-oriented programming to build a solid framework using automated rule based intelligent mechanisms to detect and classify defects in software design of SOA. The implementation part demonstrated how the framework can predict the quality level of the designed software. The results showed a good level of quality estimation can be achieved based on the number of design attributes, the number of quality attributes and the number of SOA Design Defects. Assessment shows that metrics provide guidelines to indicate the progress that a software system has made and the quality of design. Using these guidelines, we can develop more usable and maintainable software systems to fulfill the demand of efficient systems for software applications. Another valuable result coming from this study is that developers are trying to keep backwards compatibility when they introduce new functionality. Sometimes, in the same newly-introduced elements developers perform necessary breaking changes in future versions. In that way they give time to their clients to adapt their systems. This is a very valuable practice for the developers because they have more time to assess the quality of their software before releasing it. Other improvements in this research include investigation of other design attributes and SOA Design Defects which can be computed in extending the tests we performed.

This document discusses cloning an organization to allow testing and manipulation without affecting the original site. It defines cloning as creating an exact copy that can be used for tasks without risk to the original. Types of clones include the frontend design, backend design, and database. Benefits of cloning for software testing are that it is cost-effective, improves security and product quality, and increases customer satisfaction. The document then discusses various software testing types, reverse engineering, and software development life cycles like waterfall, RAD, spiral, V-model, incremental, agile, iterative, big bang and prototype models. The conclusion is that cloning can help test and learn new features without interrupting the original organization's data and business.
Software encompasses computer programs, data structures, and documentation. It is developed through software engineering processes and methods rather than manufactured. While software doesn't physically deteriorate, it does deteriorate over time due to changes. Software engineering aims to develop software through systematic, disciplined, and quantifiable approaches to achieve reliable and efficient software economically.
“Scrumbear” framework for solving traditional scrum model problemsjournalBEEI
Software engineering is a discipline that is little understood by people. It defines how software is developed and maintained to meet the clients’ requirements. Software engineers follow certain systems and standards in their work to meet the clients’ desires. It is on this background that engineers follow specific models in coming up with the final product. One of the models highly used is scrum, which is one of the agile methodologies. However, despite being highly used, it has inherent flaws that need to be corrected. Those flaws are product owner continues changing; do not accept changes in working scrum, sprint’s release time limitation, finally wasting team time within each sprint. This paper presents a new framework, which is an updated version of the current Scrum, to overcome the scum models mentioned issues. In this study, a new framework is presented in a way that is understandable and needed by software developer’s team upon the collected qualitative and quantitative data. The implementation was by making some changes to the current scrum model leading to the “Scrumbear”, certain flaws can be corrected. One of the presented changes involve adding the control master rule to ensure controlling the requirements changing.
MODEL-DRIVEN SECURITY ASSESSMENT AND VERIFICATION FOR BUSINESS SERVICES ijwscjournal
Information security covers many areas within an enterprise. Each area has security vulnerabilities and, hopefully, some corresponding countermeasures that raise the security level and
provide better protection. The fundamental concepts in information security are the security model, which outlines how security is to be implemented. A security policy outlines how data is accessed, what level of security is required, and what actions should be taken when these requirements are not met. A security model is a statement that outlines the requirements necessary to properly support and implement a certain security policy. An important concept in the design and analysis of secure systems is the security model, because it incorporates the security policy that should be enforced in the system. A model is a symbolic representation of a policy. It maps the desires of the policy makers into a set of rules that are to be followed by a computer system. In the paper we propose a model driven security assessment and verification for business service. The Security Assessment and Verification verifies whether the Application and Services are secure based on the Service Level Agreement and generates the report on the level of security features. It is designed to help business owners, operators and staff to assess the security of their business. It covers potential areas of vulnerability, and provides suggestions for adapting your security to reduce the risk of crime against your business. A security policy states that no one from a lower security level should be able to view or modify information at a higher security level, the supporting security model will outline the necessary logic and rules that need to be implemented to
ensure that under no circumstances can a lower-level subject access a higher-level object in an unauthorized manner. The security policy is an abstract term that represents the objectives and goals a system must meet and accomplish to be deemed secure and acceptable.

ANALYSIS OF LAND SURFACE DEFORMATION GRADIENT BY DINSAR cscpconf
The progressive development of Synthetic Aperture Radar (SAR) systems diversify the exploitation of the generated images by these systems in different applications of geoscience. Detection and monitoring surface deformations, procreated by various phenomena had benefited from this evolution and had been realized by interferometry (InSAR) and differential interferometry (DInSAR) techniques. Nevertheless, spatial and temporal decorrelations of the interferometric couples used, limit strongly the precision of analysis results by these techniques. In this context, we propose, in this work, a methodological approach of surface deformation detection and analysis by differential interferograms to show the limits of this technique according to noise quality and level. The detectability model is generated from the deformation signatures, by simulating a linear fault merged to the images couples of ERS1 / ERS2 sensors acquired in a region of the Algerian south.

MOVING FROM WATERFALL TO AGILE PROCESS IN SOFTWARE ENGINEERING CAPSTONE PROJE...cscpconf
Universities offer software engineering capstone course to simulate a real world-working environment in which students can work in a team for a fixed period to deliver a quality product. The objective of the paper is to report on our experience in moving from Waterfall process to Agile process in conducting the software engineering capstone project. We present the capstone course designs for both Waterfall driven and Agile driven methodologies that highlight the structure, deliverables and assessment plans.To evaluate the improvement, we conducted a survey for two different sections taught by two different instructors to evaluate students’ experience in moving from traditional Waterfall model to Agile like process. Twentyeight students filled the survey. The survey consisted of eight multiple-choice questions and an open-ended question to collect feedback from students. The survey results show that students were able to attain hands one experience, which simulate a real world-working environment. The results also show that the Agile approach helped students to have overall better design and avoid mistakes they have made in the initial design completed in of the first phase of the capstone project. In addition, they were able to decide on their team capabilities, training needs and thus learn the required technologies earlier which is reflected on the final product quality

DYNAMIC PHONE WARPING – A METHOD TO MEASURE THE DISTANCE BETWEEN PRONUNCIATIONS cscpconf
Human beings generate different speech waveforms while speaking the same word at different times. Also, different human beings have different accents and generate significantly varying speech waveforms for the same word. There is a need to measure the distances between various words which facilitate preparation of pronunciation dictionaries. A new algorithm called Dynamic Phone Warping (DPW) is presented in this paper. It uses dynamic programming technique for global alignment and shortest distance measurements. The DPW algorithm can be used to enhance the pronunciation dictionaries of the well-known languages like English or to build pronunciation dictionaries to the less known sparse languages. The precision measurement experiments show 88.9% accuracy.
INTELLIGENT ELECTRONIC ASSESSMENT FOR SUBJECTIVE EXAMS cscpconf
In education, the use of electronic (E) examination systems is not a novel idea, as Eexamination systems have been used to conduct objective assessments for the last few years. This research deals with randomly designed E-examinations and proposes an E-assessment system that can be used for subjective questions. This system assesses answers to subjective questions by finding a matching ratio for the keywords in instructor and student answers. The matching ratio is achieved based on semantic and document similarity. The assessment system is composed of four modules: preprocessing, keyword expansion, matching, and grading. A survey and case study were used in the research design to validate the proposed system. The examination assessment system will help instructors to save time, costs, and resources, while increasing efficiency and improving the productivity of exam setting and assessments.
TWO DISCRETE BINARY VERSIONS OF AFRICAN BUFFALO OPTIMIZATION METAHEURISTICcscpconf
African Buffalo Optimization (ABO) is one of the most recent swarms intelligence based metaheuristics. ABO algorithm is inspired by the buffalo’s behavior and lifestyle. Unfortunately, the standard ABO algorithm is proposed only for continuous optimization problems. In this paper, the authors propose two discrete binary ABO algorithms to deal with binary optimization problems. In the first version (called SBABO) they use the sigmoid function and probability model to generate binary solutions. In the second version (called LBABO) they use some logical operator to operate the binary solutions. Computational results on two knapsack problems (KP and MKP) instances show the effectiveness of the proposed algorithm and their ability to achieve good and promising solutions.
DETECTION OF ALGORITHMICALLY GENERATED MALICIOUS DOMAINcscpconf
In recent years, many malware writers have relied on Dynamic Domain Name Services (DDNS) to maintain their Command and Control (C&C) network infrastructure to ensure a persistence presence on a compromised host. Amongst the various DDNS techniques, Domain Generation Algorithm (DGA) is often perceived as the most difficult to detect using traditional methods. This paper presents an approach for detecting DGA using frequency analysis of the character distribution and the weighted scores of the domain names. The approach’s feasibility is demonstrated using a range of legitimate domains and a number of malicious algorithmicallygenerated domain names. Findings from this study show that domain names made up of English characters “a-z” achieving a weighted score of < 45 are often associated with DGA. When a weighted score of < 45 is applied to the Alexa one million list of domain names, only 15% of the domain names were treated as non-human generated.

IMPORTANCE OF VERB SUFFIX MAPPING IN DISCOURSE TRANSLATION SYSTEMcscpconf
This document discusses the importance of verb suffix mapping in discourse translation from English to Telugu. It explains that after anaphora resolution, the verbs must be changed to agree with the gender, number, and person features of the subject or anaphoric pronoun. Verbs in Telugu inflect based on these features, while verbs in English only inflect based on number and person. Several examples are provided that demonstrate how the Telugu verb changes based on whether the subject or pronoun is masculine, feminine, neuter, singular or plural. Proper verb suffix mapping is essential for generating natural and coherent translations while preserving the context and meaning of the original discourse.

In this paper, based on the definition of conformable fractional derivative, the functional
variable method (FVM) is proposed to seek the exact traveling wave solutions of two higherdimensional
space-time fractional KdV-type equations in mathematical physics, namely the
(3+1)-dimensional space–time fractional Zakharov-Kuznetsov (ZK) equation and the (2+1)-
dimensional space–time fractional Generalized Zakharov-Kuznetsov-Benjamin-Bona-Mahony
(GZK-BBM) equation. Some new solutions are procured and depicted. These solutions, which
contain kink-shaped, singular kink, bell-shaped soliton, singular soliton and periodic wave
solutions, have many potential applications in mathematical physics and engineering. The
simplicity and reliability of the proposed method is verified.
AUTOMATED PENETRATION TESTING: AN OVERVIEWcscpconf

It compares manual and automated penetration testing, noting that automated testing allows for faster, more standardized and repeatable tests but has limitations in developing new exploits. It also reviews some current automated penetration testing methodologies and tools, including those using HTTP/TCP/IP attacks, linking common scanning tools, a Python-based tool targeting databases, and one using POMDPs for multi-step penetration test planning under uncertainty. The document concludes that automated testing is more efficient than manual for known vulnerabilities but cannot replace manual testing for discovering new exploits.
CLASSIFICATION OF ALZHEIMER USING fMRI DATA AND BRAIN NETWORKcscpconf
Since the mid of 1990s, functional connectivity study using fMRI (fcMRI) has drawn increasing
attention of neuroscientists and computer scientists, since it opens a new window to explore
functional network of human brain with relatively high resolution. BOLD technique provides
almost accurate state of brain. Past researches prove that neuro diseases damage the brain
network interaction, protein- protein interaction and gene-gene interaction. A number of
neurological research paper also analyse the relationship among damaged part. By
computational method especially machine learning technique we can show such classifications.
In this paper we used OASIS fMRI dataset affected with Alzheimer’s disease and normal
patient’s dataset. After proper processing the fMRI data we use the processed data to form
classifier models using SVM (Support Vector Machine), KNN (K- nearest neighbour) & Naïve
Bayes. We also compare the accuracy of our proposed method with existing methods. In future,
we will other combinations of methods for better accuracy.

The document proposes a new validation method for fuzzy association rules based on three steps: (1) applying the EFAR-PN algorithm to extract a generic base of non-redundant fuzzy association rules using fuzzy formal concept analysis, (2) categorizing the extracted rules into groups, and (3) evaluating the relevance of the rules using structural equation modeling, specifically partial least squares. The method aims to address issues with existing fuzzy association rule extraction algorithms such as large numbers of extracted rules, redundancy, and difficulties with manual validation.
PROBABILITY BASED CLUSTER EXPANSION OVERSAMPLING TECHNIQUE FOR IMBALANCED DATAcscpconf
In many applications of data mining, class imbalance is noticed when examples in one class are
overrepresented. Traditional classifiers result in poor accuracy of the minority class due to the
class imbalance. Further, the presence of within class imbalance where classes are composed of
multiple sub-concepts with different number of examples also affect the performance of
classifier. In this paper, we propose an oversampling technique that handles between class and
within class imbalance simultaneously and also takes into consideration the generalization
ability in data space. The proposed method is based on two steps- performing Model Based
Clustering with respect to classes to identify the sub-concepts; and then computing the
separating hyperplane based on equal posterior probability between the classes. The proposed
method is tested on 10 publicly available data sets and the result shows that the proposed
method is statistically superior to other existing oversampling methods.
CHARACTER AND IMAGE RECOGNITION FOR DATA CATALOGING IN ECOLOGICAL RESEARCHcscpconf
Data collection is an essential, but manpower intensive procedure in ecological research. An
algorithm was developed by the author which incorporated two important computer vision
techniques to automate data cataloging for butterfly measurements. Optical Character
Recognition is used for character recognition and Contour Detection is used for imageprocessing.
Proper pre-processing is first done on the images to improve accuracy. Although
there are limitations to Tesseract’s detection of certain fonts, overall, it can successfully identify
words of basic fonts. Contour detection is an advanced technique that can be utilized to
measure an image. Shapes and mathematical calculations are crucial in determining the precise
location of the points on which to draw the body and forewing lines of the butterfly. Overall,
92% accuracy were achieved by the program for the set of butterflies measured.
SOCIAL MEDIA ANALYTICS FOR SENTIMENT ANALYSIS AND EVENT DETECTION IN SMART CI...cscpconf
Smart cities utilize Internet of Things (IoT) devices and sensors to enhance the quality of the city
services including energy, transportation, health, and much more. They generate massive
volumes of structured and unstructured data on a daily basis. Also, social networks, such as
Twitter, Facebook, and Google+, are becoming a new source of real-time information in smart
cities. Social network users are acting as social sensors. These datasets so large and complex
are difficult to manage with conventional data management tools and methods. To become
valuable, this massive amount of data, known as 'big data,' needs to be processed and
comprehended to hold the promise of supporting a broad range of urban and smart cities
functions, including among others transportation, water, and energy consumption, pollution
surveillance, and smart city governance. In this work, we investigate how social media analytics

SOCIAL NETWORK HATE SPEECH DETECTION FOR AMHARIC LANGUAGEcscpconf
The anonymity of social networks makes it attractive for hate speech to mask their criminal
activities online posing a challenge to the world and in particular Ethiopia. With this everincreasing
volume of social media data, hate speech identification becomes a challenge in
aggravating conflict between citizens of nations. The high rate of production, has become
difficult to collect, store and analyze such big data using traditional detection methods. This
paper proposed the application of apache spark in hate speech detection to reduce the
challenges. Authors developed an apache spark based model to classify Amharic Facebook
posts and comments into hate and not hate. Authors employed Random forest and Naïve Bayes
for learning and Word2Vec and TF-IDF for feature selection. Tested by 10-fold crossvalidation,
the model based on word2vec embedding performed best with 79.83%accuracy. The
proposed method achieve a promising result with unique feature of spark for big data.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

1. INTRODUCTION TO AGILE MODELED LAYERED SECURITY
ARCHITECTURES AND LITERATURE SURVEY
Software Engineering covers the definition of processes, techniques and models suitable for its
environment to guarantee quality of results. For Software Architecture the requirements gathering
and analysis is done using MDA (Model-Driven Architecture) which is a layered architecture. To
provide security to the architecture various security techniques are used as agile methodologies.
This states that Secure Software Architecture will improve the Requirements.
Software Architecture: An important design artifact in any software development project, with the
possible exception of very small projects, is the Software Architecture. An important part of any
architecture is the set of Architectural Design Rules. Architectural Design Rules are defined as
the rules, specified by the architect(s) that need to be followed in the detailed design of the
system. A primary role of the architecture is to capture the architectural design decisions. An
important part of these design decisions consists of architectural design rules [1].
Security: Security ensures that information is provided only to those users who are authorized to
possess the information. Security generally includes the following:
Identification: This assumes that system must check whether a user really is whom he or she
claims to be. There are many techniques for identification and it is also called as authentication.
The most widely used is “Username/Password” approach. More sophisticated techniques based
on biometrical data are like retinal fingerprint scan.
Authorization: This means that the system should provide only the information that the user is
authorized for, and prevent access to any other information. Authorization usually assumes
defining “user access rights”, which are settings that define to which operations, data, or features
of the system the user, does have access.
Encryption: This transforms information so that unauthorized users (who intentionally or
accidentally come into its possession) cannot recognize it [11].
MDA: Model-Driven Development (MDD) is a modeling approach. The basic premise of Model-
Driven Development is to capture all important design information in a set of formal or
semiformal models, which are kept consistent automatically. To realize full benefits of MDD,
formalize architecture design rules, which then allow automatic enforcement of architecture on
the system model. There exist several approaches to MDD, such as OMG’s (Object Management
Group) MDA (Model-Driven Architecture), Domain Specific Modeling (DSM), and Software
factories fro Microsoft. Model-Driven Architecture prescribes that three models or sets of models
shall be developed as:
The Computationally Independent Model(s) (CIM) captures the requirements of the system.
The Platform-Independent Model(s) (PIM) captures the systems functionality without considering
any particular execution platform.
The Platform-Specific Model(s) (PSM) combines the specifications in the PIM with the details
that specify how the system uses a particular type of platform. The PSM is a transformation of the
PIM using a mapping either on the type level or at the instance level.
MDA does not directly address architectural design or how to represent the architecture, but the
architecture has to be captured in the PIM or in the mapping since the CIM captures the
requirements and the PSM is generated from the PIM using the mapping [1].
Agile Methods: Over the past few years, a new family of software engineering methods has
started to gain acceptance amongst the software development community. These methods,
collectively called Agile Methods, conform to the Agile Manifesto, which states “We are
uncovering better ways of developing software by doing it and helping others does it. Through
3. 234 Computer Science & Information Technology (CS & IT)
this work we have come to value: Individuals and interactions over processes and tools working
software over comprehensive documentation customer collaboration over contract negotiation
responding to change over following a plan That is, while there is value in the items on the right,
we value the items on the left more.” The individual agile methods include Extreme Programming
(XP), Scrum, Lean Software Development, Crystal Methodologies, Feature Driven Development
(FDD), and Dynamic Systems Development Methodology (DSDM). While there are many
differences between these methodologies, they are based on some common principles, such as
short development iterations, minimal design upfront, emergent design and architecture,
collective code ownership and ability for anyone to change any part of the code, direct
communication and minimal or no documentation (the code is the documentation), and gradual
building of test cases. Some of these practices are in direct conflict with secure SDLC processes
[2].
2. DESIGNING DEPENDABLE PRIVACY REQUIREMENTS USING AGILE MODELD
LAYERED SOLUTIONS
Security Requirements: Agile information systems and software methods are characterized by
nimbleness to rapid changes, multiple incremental iterations and a fast development pace. Agile
development is defined as a set of principles and practices that differs as a whole from traditional
planned development. The major principles for agile information systems and software methods
include [9]:
Accept multiple valid approaches: A stable architecture, a tool orientation and component based
development combine to enable a “fluid view” of methodology and the value of tailoring the
methodology for each development project. Improvisation in development approach will help
match the methodology to the constraints of the project environment.
Engage the customer: Close involvement of customers in the project enables accurate and fast
requirements elicitation, and the customers again immediate satisfaction as their ideas and
requirements arise in each new release.
Accommodate requirements change: Agility means that developers quickly and easily respond to
the shifting requirements driven by the changing environment for which the software is intended.
Build on successful experience: The “right” people are important for project success in order to
foster innovation in software development. Courage, specific knowledge, intelligence, and
commitment are needed for agile development.
Develop good teamwork: The right mix of people operating with the right process framework
means that the right mix of knowledge and working style will be present in the project. Agile
development teams must often come together quickly and be immediately effective.
Agile practices include:
Develop in parallel: Releases may be completely developed in parallel, or staged onto the market
such that design, development, and quality assurance are all taking place simultaneously, but
sequentially on different releases. Coding may even begin before the requirements are declared.
Release more often: Releases are scoped to more frequently deliver small sets of new features and
fixes. Constant re-prioritization of features enables responsiveness to changing requirements and
enables features to easily slip from one release to the next.
Depend on tools: Heavy use of development tools and environment that speed up the design and
coding process offer much of the functionality that used to be custom built. Ideally, agile
developers try to avoid wasting time repetitively building features others have already developed.
Implant customers in the development environment: Fast and intimate access to customer views
and opinions slashes time, and ensures the high-priority features are built first. When customers
participate closely in all phases of development, cycle times shorten and teams can better chuck
requirements into logical releases from customer views.
Establish a stable architecture: This anchors a rapid development process that is never quite
stable, yet each release has some similarity and components reuse.
4. Computer Science & Information Technology (CS & IT) 235
Assemble and reuse components: Never unnecessarily build software from scratch when it can be
assembled from existing components. It is quicker and equally effective to acquire, integrate, and
assemble components with wrappers, including business logic software, interfaces and back-end
infrastructure.
Ignore maintenance: Building components for short life spans eliminates the need for
documentation. Assembled software can be thrown away and reassembled with greater ease than
maintaining complex and custom-build components.
Tailor the methodology daily: Operating with an overall development framework, but allowing
project teams to adjust the exact approach to the daily situation, enabled teams to meet intense
demands for speed by skipping unnecessary tasks or phases. Use just enough process to be
effective, and no more.
Security requirements for Agile Security methods and Extant Security methods:
Requirements for security methods that are targeted to be integrated into agile software methods:
The security approach must be adaptive to agile software development methods.
They must be simple; they should not hinder to the development project.
The security approach, in order to be integrated successfully with agile development methods,
should offer concrete guidance and tools at all phases of development (i.e., from requirements
capture to testing).
A successful security component should be able to adapt rapidly to ever changing requirements
owing to a fast-paced business environment, including support for handling several incremental
iterations [10].
Key Security Elements in Agile Software Development:
The key security element stems from information security “meta-notation”, or notation for
notations, and database security. Apply these key security elements to a process aimed at
developing secure software in an agile manner. This generic security process consists of these key
security elements in different phases of software development (requirements analysis, design,
implementation and testing). These steps are not necessarily sequential and in any case, every
step is optional [9].
3. IMPLEMENTATIONS AND VALIDATIONS – WEB SERVICES CASE STUDY
Privacy is a well recognized sticking point in the Web Services network. In this case study
implementation, we explore privacy protection brings about many new security challenges. Web
Services extended Cloud computing is the long dreamed vision of computing as a utility, where
users can remotely store their data into the cloud so as to enjoy the on-demand high quality
applications and services from a shared pool of configurable computing resources. By data
outsourcing, users can be relieved from the burden of local data storage and maintenance. Here
data (i.e., message/file) is transferred between the sender and the receiver in a extensively secure
manner. Hence the communication between the sender and receiver is guaranteed by the Third
Party Auditor (TPA).The software is designed in such a way that the user can easily interact with
the screen because they are GUI and screen has several buttons with captions indicating the
functionality like Sender details, message typed, searching for a file, keys and signatures
generated, shows the encrypted data, verification of data, system name details, Receiver details.
Business layer of this application are to be developed in such a way they must be easily
maintainable and extensible. Software developed will able to do ant type of data transfer between
sender and receiver in an authenticated, privacy of data contents.
Refer to the Figure 1, 2, 3 which provides the class diagram, sequence diagram and execution
screen shot respectively of the privacy web services application implemented.

Validation of the Privacy Web Services Application: MDA with executable UML offers an
approach that embodies all the key ingredients of the process for developing dependable systems,
by offering: A uniform strategy for preserving investment in existing models built using
unsupported tools, by automatically migrating them to profiled UML models for subsequent
maintenance and development using state of the art UML tools; A clean separation of application
behavior from the platform specific implementation using technologies such as Integrated
Modular Avionics (IMA), allowing the full potential of IMA to be realized in a consistent and
dependable way; A semantically well defined formalism that can be used a basis for modular
certification of safety related systems; The ability to generate not only the components of the
target system, but components of development tool chain, providing scope for model translation
and offering “executable specifications” that can be tested early and mapped reliably onto the
target, leading to greater levels of dependency.
MDA is a new approach for most organizations, and therefore carries additional training and
learning curve costs and also currently the availability of production quality code generators is
currently limited. MDA requires developers to work at a more abstract level than code although
experience shows that most do not have any difficulty making the adjustment, there will be some
who find this change of emphasis difficult to achieve. Building upon the initial success of MDA
deployment so far, work is now proceeding on the enhancement of Ada code mapping rules to
cover the entire xUML formalism. Work is also underway to develop a generic “adapter/router”
component to provide a standard component to provide a standard way to interface re-engineered
xUML components with pre-existing components. These techniques are now being applied to
another avionics system in the same organization, in response to the customers need for a faster
and cheaper upgrade capability. While we consider systematically all actions within a use case
and analyze how they could be subverted, it produces all (or most) of the threats to a given
application. While all this could be done in textual version of the use case, the use of UML
activity diagrams produces a clear and more intuitive way to analyze these attacks. From the
threats we derive necessary policies to stop or mitigate them. Refer to the Figures 4,5, 6 which
provides the validated class diagram, sequence diagram and detailed sequence diagrams
respectively of the previous implemented privacy web services application.

4. CONCLUSIONS
In this paper the major part is given to model architectural design rules using MDA so that
architects and developers are responsible to automatic enforcement on the detailed design and
easy to understand and use by both of them. This MDA approach is implemented in use of Agile
strategy in three different phases covering three different layers to provide security to the system.
With this procedure a conclusion has been given that with the system security the requirements
for that system are improved. This paper summarizes that security is essential for every system at
initial stage and upon introduction of security at middle stage must lead to the change in the
system i.e., an improvement to system requirements.
