This is a paper presentation held by Dr. Yiannis Verginadis at the 1st International Workshop on Cloud Security and Data Privacy by Design (CloudSPD'15) in Limassol, Cyprus.
In an organization specifically as virtual as cloud there is need for access control systems to constrain
users direct or backhanded action that could lead to breach of security. In cloud, apart from owner access
to confidential data the third party auditing and accounting is done which could stir up further data leaks.
To control such data leaks and integrity, in past several security policies based on role, identity and user
attributes were proposed and found ineffective since they depend on static policies which do not monitor
data access and its origin. Provenance on the other hand tracks data usage and its origin which proves the
authenticity of data. To employ provenance in a real time system like cloud, the service provider needs to
store metadata on the subject of data alteration which is universally called as the Provenance Information.
This paper presents a provenance-policy based access control model which is designed and integrated with
the system that not only makes data auditable but also incorporates accountability for data alteration
events.
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.
RANKING CRITERIA OF ENTERPRISE INFORMATION SECURITY ARCHITECTURE USING FUZZY ...ijcsit
This document summarizes a research study that aimed to identify and prioritize important criteria for enterprise information security architecture (EISA) using a fuzzy TOPSIS method. The researchers first reviewed literature on EISA frameworks and extracted major criteria across dimensions like standards, policies, infrastructure, user training, risk assessment, and compliance. They designed a questionnaire to rate the criteria and analyzed the responses from 15 information security experts using fuzzy TOPSIS. The results showed that database/database security, internal software security, electronic data exchange security, and malware monitoring were high priority criteria for effective EISA.
The document discusses mobile security and provides recommendations for organizations. It covers the following key points:
1. Mobility has introduced new security risks as the traditional network perimeter is broken and devices are used outside an organization's control. This includes risks from lost devices, insecure networks, overlap of personal and work usage, and cloud data storage.
2. A layered mobile security strategy is recommended, with security controls embedded in policies, infrastructure, applications, and data. Organizations should define acceptable usage policies and deploy mobile device management to monitor compliance.
3. Application security is also important, with recommendations to use secure development practices, test apps for vulnerabilities, and encrypt sensitive data. A defense-in-depth approach combining
The document discusses various principles and methods of access control, including:
1) Three main principles of access control are identity, authority, and accountability. Identity establishes a user's identity, authority authorizes access privileges, and accountability tracks user actions.
2) Common methods to establish identity include passwords, tokens, biometrics, and digital certificates. Multifactor authentication combines multiple methods for stronger security.
3) Access control models like Bell-LaPadula and Biba are used to enforce security policies based on confidentiality, integrity, and transactions. Clark-Wilson defines processes to control access to critical data items.
According to research findings, Securonix, with the comprehensive UEBA solution, has received the highest overall ratings and is positioned as the 2018 technology leader in the global UEBA market.

1) The document discusses Enterprise Information Security Architecture (EISA), which provides a comprehensive approach to implement security architecture across an enterprise aligned with business objectives.
2) Implementing EISA has advantages like protecting the organization from cyber threats by identifying vulnerabilities, integrating security tools, and boosting stakeholder confidence, but faces challenges like identifying all organizational assets, prioritizing investments, customizing security tools to business processes, and changing organizational strategy.
3) The key steps to implement EISA include conducting a current state assessment, identifying critical assets and threats, designing and testing risk treatment plans and security controls, and periodically reviewing and updating the architecture.
This document discusses different methodologies for access control and their interactions. It begins by introducing access control as a major security component for organizations to implement regulatory constraints. It then describes several common access control models in more detail, including Mandatory Access Control (MAC), Discretionary Access Control (DAC), and Role-Based Access Control (RBAC). MAC controls access based on a system-wide security policy, while DAC allows individual users some control over access permissions. The document analyzes advantages and limitations of each model and their suitability for different environments.
Risk-driven and Business-outcome-focused Enterprise Security Architecture Fra...Craig Martin
Ana Kukec, Lead Enterprise Security Consultant, Enterprise Architects, Australia
The Open Group Architecture Forum and Security Forum agree that the coverage of security in TOGAF should be updated and improved. The understanding and focus of security architecture has moved from a threat-driven approach of addressing non-normative flaws through systems and applications to a risk-driven and business outcome-focused methodology of enabling a business strategy.
Following this trend, we defined fundamental characteristics of effective security architecture. 1) Capabilities are primary assets at risk, while information systems and technology components are secondary assets at risk supporting the primary assets. 2) Security requirements include the business aspects and not only the technology aspects of confidentiality, integrity and availability. 3) IT risk management is business-opportunity-driven. It requires understanding of risk appetite across business, information systems and technology architecture to manage security risks of vulnerabilities and compliance issues, which may arise at any layer of enterprise architecture in a business-outcome-focused way. 4) Security services are aligned to business drivers, goals and objectives, and managed in a risk-driven way.
Yet, there is no single security architecture development methodology to deliver these characteristics. We believe that existing information security standards and frameworks in a combination with the TOGAF are sufficient to meet the aforementioned fundamental characteristics of effective security architecture. However the challenge is in their integration. Our Enterprise Security Architecture Framework integrates key industry standards and best practices for information security and risk management, such as COBIT 5 for Information Security, ITILv3 Security Service Management, ISO/IEC 27000 and ISO/IEC 31000 families of standards, using the TOGAF Architecture Development Method and Content Meta-model as the key integrators. It is a pragmatic security architecture framework which establishes a common language between IT, security, risk and business organisations within an enterprise and ensures effective and efficient support of long-term security needs of both business and IT, with a risk-driven enterprise as a final outcome.
We will present a case study of the implementation of the aforementioned business-outcome-focused and risk-driven Enterprise Security Architecture Framework at the University of New South Wales.
Key takeaways:
-- Overview of a risk-driven and business-outcome-focused security architecture methodology seamlessly integrated with the TOGAF
-> Security strategic planning
-> Enterprise-wide compliance, internal (policies and standards) and external (laws and regulations
-> Business-opportunity driven management of security risk of threats, vulnerabilities and compliance issues across business, information systems and technology architecture
Ea Relationship To Security And The Enterprise V1pk4
The document discusses different frameworks and methodologies for enterprise architecture (EA) and enterprise security architecture (SA). EA focuses on optimizing business value through mapping business activities, while SA focuses on protecting business assets through a balanced security program. SA goals depend on an organization's risk management culture, which can range from generative to bureaucratic to pathologic. The document provides examples of using the TOGAF and Federal EA frameworks to structure SA.
IRJET- Attribute Based Access Control in Personal Health Records using Cloud ...IRJET Journal
This document proposes using attribute-based access control and encryption to securely share personal health records (PHRs) stored in the cloud. It discusses how attribute-based encryption (ABE) can allow PHR owners to encrypt their records according to an access policy that determines who can access them. The proposed system would use an ABE mechanism to authorize access for requesting users based on the policy, and proxy re-encryption to allow approved users to decrypt specified PHR files stored in the cloud. This provides security, privacy and confidentiality for outsourced PHR data while allowing flexible access for authorized medical and personal users.

Most of the Jordanian universities’ inquiries systems, i.e. educational, financial, administrative, and research systems are accessible through their campus networks. As such, they are vulnerable to security breaches that may compromise confidential information and expose the universities to losses and other risks. At Jordanian universities, security is critical to the physical network, computer operating systems, and application programs and each area has its own set of security issues and risks. This paper presents a comparative study on the security systems at the Jordanian universities from the viewpoint of prevention and intrusion detection. Robustness testing techniques are used to assess the security and robustness of the universities’ online services. In this paper, the analysis concentrates on the distribution of vulnerability categories and identifies the mistakes that lead to a severe type of vulnerability. The distribution of vulnerabilities can be used to avoid security flaws and mistakes.

Key enterprise mobility trends in 2015 included context awareness, autonomy of devices to make decisions, and a focus on notifications. Applications needed to be aware of bring-your-own-device policies to protect enterprise data. Security became multifactor with context awareness while platforms scaled to handle large volumes of data from a growing number of devices and content types. Mobility management integrated with IT systems to support a growing mobile workforce.
1. The document discusses the relationship between information security and security architecture, noting that while they are complementary, they are often confused or conflated in practice.
2. It recommends developing strategic plans and implementation schedules for both information security and security architecture to better disentangle their spans of control, authorities, and skill set requirements.
3. Having clearly defined strategic plans would help manage the "practice edges" between information security and security architecture.
Does Anyone Remember Enterprise Security Architecture?rbrockway
The concept of Enterprise Security Architecture (ESA) is not new (Gartner 2006), yet the numbers from the past several years’ worth of breach data indicates that most organizations continue to approach security on a project by project basis or from a compliance perspective. This talk will refresh the ESA concept and communicate tangible and realistic steps any organization can take to align their security processes, architecture and management to their business strategies, reduce business risks and significantly improve their overarching security posture.
This document provides an overview of conceptual security architecture using the SABSA framework. It describes key concepts like security architecture, enterprise frameworks, control objectives, multi-layered security strategies, security entity models, security domains, and security lifetimes and deadlines. The goal is to conceptualize security at a high level to address business risks and requirements through control objectives and a multi-layered approach using concepts like entities, domains, and relationships of trust.
CONTEXT, CONTENT, PROCESS” APPROACH TO ALIGN INFORMATION SECURITY INVESTMENTS...ijsptm
Today business environment is highly dependent on complex technologies, and information is considered
an important asset. Organizations are therefore required to protect their information infrastructure and
follow an inclusive risk management approach. One way to achieve this is by aligning the information
security investment decisions with respect to organizational strategy. A large number of information
security investment models have are in the literature. These models are useful for optimal and cost-effective
investments in information security. However, it is extremely challenging for a decision maker to select one
or combination of several models to decide on investments in information security controls. We propose a
framework to simplify the task of selecting information security investment model(s). The proposed
framework follows the “Context, Content, Process” approach, and this approach is useful in evaluation
and prioritization of investments in information security controls in alignment with the overall
organizational strategy.
The document provides an overview of the Cybersecurity Capability Maturity Model (C2M2). The C2M2 focuses on implementing and managing cybersecurity practices for information, IT, and OT assets. It can be used to strengthen cybersecurity capabilities, evaluate capabilities, share best practices, and prioritize improvements. The model includes 342 practices organized across 10 domains. It uses a scale of 0-3 maturity indicator levels (MILs) to assess progression in each domain. Higher MILs indicate more advanced, institutionalized, and consistent implementation of practices. The document outlines how organizations can use the C2M2 by performing a self-evaluation, identifying gaps, prioritizing improvements, and implementing plans in an

This document discusses the Flexigrip sternal closure system for primary sternal closure in cardiac surgery. Flexigrip clips are made of a nickel-titanium alloy that becomes malleable below 100 degrees Celsius and regains its shape above 250 degrees Celsius. The implantation technique involves creating holes in the sternum, placing wires to secure the manubrium and xiphoid process, inserting malleable clips that regain their shape upon application of a warm solution. An initial experience with 12 patients found no issues with emergency resternotomy. Flexigrip provides an enhanced surface area for lower stress compared to traditional through-bone wiring or stapling techniques while maintaining sternal flexibility and avoiding ischemia.
This document discusses Neoveil, a bioabsorbable reinforcement felt made of polyglycolic acid (PGA). PGA is a soft, non-woven fabric with elasticity that is fabricated through a specific process and has excellent biocompatibility as it is used as a suture material. The PGA felt is completely absorbed within 15 weeks through hydrolysis, absorption, and metabolization. It is used to prevent air leakage and reduce pneumothorax by reinforcing weak organs like lungs and bronchi. The document describes how to use the PGA felt sheets and tubes, including spreading the sheet across the lung and stapling the tube. It also references two scientific publications evaluating its use and surgical morbidity

PLANT LEAF DISEASES IDENTIFICATION IN DEEP LEARNINGCSEIJJournal
Crop diseases constitute a big threat to plant existence, but their rapid identification remains difficult in many parts of the planet because of the shortage of the required infrastructure. In computer vision, plant leaf detection made possible by deep learning has paved the way for smartphone-assisted disease diagnosis. employing a public dataset of 4,306 images of diseased and healthy plant leaves collected under controlled conditions, we train a deep convolutional neural network to spot one crop species and 4 diseases (or absence thereof). The trained model achieves an accuracy of 97.35% on a held-out test set, demonstrating the feasibility of this approach. Overall, the approach of coaching deep learning models on increasingly large and publicly available image datasets presents a transparent path toward smartphoneassisted crop disease diagnosis on a large global scale. After the disease is successfully predicted with a decent confidence level, the corresponding remedy for the disease present is displayed that may be taken as a cure.

An Enhancement Role and Attribute Based Access Control Mechanism in Big Data IJECEIAES
To be able to leverage big data to achieve enhanced strategic insight and make informed decision, an efficient access control mechanism is needed for ensuring end to end security of such information asset. Attribute Based Access Control (ABAC), Role Based Access Control (RBAC) and Event Based Access Control (EBAC) are widely used access control mechanisms. The ABAC system is much more complex in terms of policy reviews, hence analyzing the policy and reviewing or changing user permission are quite complex task. RBAC system is labor intensive and time consuming to build a model instance and it lacks flexibility to efficiently adapt to changing user’s, objects and security policies. EBAC model considered only the events to allocate access controls. Yet these mechanisms have limitations and offer feature complimentary to each other. So in this paper, Event-Role-Attribute based fine grained Access Control mechanism is proposed, it provide a flexible boundary which effectively adapt to changing user’s, objects and security policies based on the event. The flexible boundary is achieved by using temporal and environment state of an event. It improves the big data security and overcomes the disadvantages of the ABAC and RBAC mechanisms. The experiments are conducted to prove the effectiveness of the proposed Event-Role-Attribute based Access Control mechanism over ABAC and RBAC in terms of computational overhead.
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.

Introduction
Information security is defined as the means by which data in computer systems are protected. The protection will is designed to ensure that the confidentiality, integrity, and availability of the data is maintained. Regardless, the proposal of the (my?) organization is that it is to provide data analytics services to various companies in the health sector. By taking advantage of emerging technologies such as cloud computing the company will not only be able to offer its services at competitive rates but will also be able to improve overall performance whilst ensuring data security (Peltier, 2016). Cloud computing, in general, refers to the delivery of computer resources from applications to data centers such as those that will be owned by the company. The basis of this strategy is to have easily available and secured data over the internet. Moreover, it has also been identified that the cloud service to be used is Software as a service (SaaS) (Peltier, 2016). It is the use of an application that is run by a distant computer on the cloud via a browser or internet-based application. By understanding this basis of operations, it willwe can better demonstrate how information security will be attained. Comment by Mark O'Connell: Is that a direct quote? “Ensuring” is a pretty bold word. Not much is guaranteed in InfoSec. Comment by Mark O'Connell: In your final report this will probably be redundant with the cloud section
Reasoning
The SaaS approach was selected for numerous reasons among them, its high flexibility and attractive nature to the clients. Additionally, by simplifying its installation and overall utilization, it eliminates security vulnerabilities. With security as its core value, the SaaS approach to cloud computing offered eliminates control over the hardware by the client (McCoy & Perlis, 2018). This approach is necessary for numerous reasons among them is the fact that having the hardware installed within the organization it will make itnot be as well protected as that provided by the CSP and it might become vulnerable to outside attacks, human error, and malicious employee activities all of which can result in data loss. This realization was after a study conducted by Accense, an analytical company, during the period of 2009 and 2014, the number of cyberattacks increased drastically if the client used on-premises servers instead of cloud-based servers (McCoy & Perlis, 2018). According to their figures, the numbers rose from a total of just over 3 million attacks per year to over 42 million attacks. For example, in 2017, the total number of data breaches cost companies an approximate of $3.6 million (McCoy & Perlis, 2018). With the figure expected to be significantly higher in 2019, the best approach to limiting cyberattacks and overall data breaches is by employing SaaS ...
IT SECURITY PLAN FOR FLIGHT SIMULATION PROGRAMIJCSEA Journal
Information security is one of the most important aspects of technology, we cannot protect the best interests of our organizations' assets (be that personnel, data, or other resources), without ensuring that these assetsare protected to the best of their ability. Within the Defense Department, this is vital to the security of not just those assets but also the national security of the United States. Compromise insecurity could lead severe consequences. However, technology changes so rapidly that change has to be made to reflect these changes with security in mind. This article outlines a growing technological change (virtualization and cloud computing), and how to properly address IT security concerns within an operating environment. By leveraging a series of encrypted physical and virtual systems, andnetwork isolation measures, this paper delivered a secured high performance computing environment that efficiently utilized computing resources, reduced overall computer processing costs, and ensures confidentiality, integrity, and availability of systems within the operating environment
DISSERTATION ALGORITHM DEVELOPMENT TIPS FOR DEVELOPING SECURE AND FLEXIBLE MA...Tutors India
The document discusses developing secure and flexible management policies for multiple users and cloud systems. It emphasizes the need for effective identity and access management (IAM) to securely manage user identities and grant access to resources. IAM involves authentication, authorization, and managing identities and infrastructure to support resource access control. The document also recommends enhancing performance through key-based authentication and flexible authorization policies for multi-party data sharing in cloud infrastructure.
A USER PROFILE BASED ACCESS CONTROL MODEL AND ARCHITECTUREIJCNC
Personalization and adaptation to the user profile capability are the hottest issues to ensure ambient
assisted living and context awareness in nowadays environments. With the growing healthcare and
wellbeing context aware applications, modeling security policies becomes an important issue in the
design of future access control models. This requires rich semantics using ontology modeling for the
management of services provided to dependant people. However, current access control models remain
unsuitable due to lack of personalization, adaptability and smartness to the handicap situation.
In what ways do you think the Elaboration Likelihood Model applies.docxjaggernaoma
This document summarizes common vulnerabilities observed in critical infrastructure control systems based on vulnerability assessments conducted by Sandia National Laboratories. It finds that most vulnerabilities stem from a lack of proper security administration, including failing to define security classifications for system data, establish security perimeters, implement defense-in-depth protections, and restrict access based on operational needs. Many vulnerabilities result from deficient or nonexistent security governance, budget constraints, personnel attrition, and a lack of security training for automation administrators. Comprehensive mitigation requires improved security awareness, strong governance, and configuration of technology to remedy vulnerabilities.
IRJET-Implementation of Threshold based Cryptographic Technique over Cloud Co...IRJET Journal
This document discusses implementing a threshold-based cryptographic technique for data and key storage security over cloud computing. It proposes a system that encrypts data stored on the cloud to prevent unauthorized access and data attacks by the cloud service provider. The system uses a threshold-based cryptographic approach that distributes encryption keys among multiple users, requiring a threshold number of keys to decrypt the data. This prevents collusion attacks and ensures data remains secure even if some user keys are compromised. The implementation results show the system can effectively secure data on the cloud and protect legitimate users from cheating or attacks from the cloud service provider or other users.
Welcome to International Journal of Engineering Research and Development (IJERD)IJERD Editor
This document summarizes a research thesis that proposes a trusted cloud computing platform (TCCP) to address critical security issues in cloud computing. The TCCP is designed to provide a closed box execution environment for virtual machines to guarantee confidentiality and integrity of computations outsourced to infrastructure as a service cloud providers. It allows customers to remotely verify whether a cloud provider's backend is running a trusted TCCP implementation before launching a virtual machine. The TCCP leverages advances in trusted computing technologies to securely manage virtual machines and cloud infrastructure through protocols for node registration and virtual machine launch and migration. The goal of the TCCP is to extend the capabilities of traditional trusted platforms to the complex, distributed environments of cloud computing infra
This document discusses the state of the art in distributed database security over several decades. It covers topics like multilevel security approaches from the 1980s using distributed data/centralized control. Later sections discuss the inference problem, Hippocratic databases in the 1990s-2000s, trusted mediators, blind comparers, and improving blind comparers with fake queries and declassification. Federated database security is also covered, focusing on access control, identity management and authorization. Integrated distributed database security research from the late 1990s onward integrating policies is summarized as well.
The paradigm called “Cloud computing” acts as a mechanism for attaining the resources of shared technology and infrastructure cost-effectively. The on-demand services are accomplished to execute the various operations across the network. Regularly, the last client doesn't know about the area of open physical assets and devices. Developing, using, and dealing with their applications 'on the cloud', which includes virtualization of assets that keeps and guides itself are led by arranged activities to clients. Calculation experience the new methodology of cloud computing which perhaps keeps the world and can set up all the human necessities. At the end of the day, cloud computing is the ensuing normal step in the development of on-request data innovation administrations and items. The Cloud is an allegory for the Internet and is an idea for the secured confused foundation; it likewise relies upon drawing network graphs on a computer. In this work, thorough investigations of distributed computing security and protection concerns are given. The work distinguishes both the identified and unidentified attacks, vulnerabilities in the cloud, security attacks and also the solutions to control these threats and attacks. Moreover, the restrictions of the present solutions and offers various perceptions of security viewpoints are distinguished and explored. At long last, a cloud security system is given in which the different lines of protection and the reliance levels among them are identified.

Separation in a network is essential, of course. It would be more annoyed with that much knowledgeability and security features if it were only about security. However, it makes this network much more flexible, and in some ways makes it more secure. It reduces the potential for internal and external attacks on the same network and makes it harder for someone to take over the network. Furthermore, this separation keeps our data away from third parties. Separation of access is essential in a network, for example, to ensure that a user cannot access the whole network. It is common for specific applications and software installations on the personal computer to operate in the background. In this regard, it is possible to customize the software operating mode to make the software operation hidden to not be visible to the user. No one server or group of servers is going to have to withstand many other servers. The first line of defense in any IT environment is resource partitioning to enable critical infrastructure to handle all requests without overloading the primary server (Jaeger et al., 2016).
Separation is basically the process of using multiple processes with some type of separation for Process separation of access to objects and data. Separation (or transient segregation) can occur in both physical and logical network segments. The trick with security is to keep it away from the IT infrastructure. For example, a firewall is still strictly considered a technical security tool because it is not supposed to affect business activities. it is possible to separate administrative control, physical systems, and data between those with different roles within the organization. The behavior within the network is like partitioning an IT environment into discrete services, although some elements of this concept have not been adopted in Active Directory–in particular, policies and modules. A system administrator can move control of the administrative control of physical systems or systems within the network to a different server. However, when implementing security controls on deployments, it becomes essential to understand the scale at which the resources need to be distributed. Simply put, separation makes IT more secure (Liu et al., 2019).

AUTHENTICATION SCHEME FOR DATABASE AS A SERVICE(DBAAS) ijccsa
IT Companies have shifted their resources to the cloud at rapidly increasing rate. As part of this trend companies are migrating business critical and sensitive data stored in database to cloud-hosted and Database as a Service (DBaaS) solutions.Of all that has been written about cloud computing, precious little attention has been paid to authentication in the cloud. In this paper we have designed a new effective authentication scheme for Cloud Database as a Service (DBaaS). A user can change his/her password,
whenever demanded. Furthermore, security analysis realizes the feasibility of the proposed model for DBaaS and achieves efficiency. We also proposed an efficient authentication scheme to solve the authentication problem in cloud. The proposed solution which we have provided is based mainly on improved Needham-Schroeder’s protocol to prove the users’ identity to determine if this user is authorized or not. The results showed that this scheme is very strong and difficult to break it.

Candidate young stellar objects in the S-cluster: Kinematic analysis of a sub...Sérgio Sacani
Context. The observation of several L-band emission sources in the S cluster has led to a rich discussion of their nature. However, a definitive answer to the classification of the dusty objects requires an explanation for the detection of compact Doppler-shifted Brγ emission. The ionized hydrogen in combination with the observation of mid-infrared L-band continuum emission suggests that most of these sources are embedded in a dusty envelope. These embedded sources are part of the S-cluster, and their relationship to the S-stars is still under debate. To date, the question of the origin of these two populations has been vague, although all explanations favor migration processes for the individual cluster members. Aims. This work revisits the S-cluster and its dusty members orbiting the supermassive black hole SgrA* on bound Keplerian orbits from a kinematic perspective. The aim is to explore the Keplerian parameters for patterns that might imply a nonrandom distribution of the sample. Additionally, various analytical aspects are considered to address the nature of the dusty sources. Methods. Based on the photometric analysis, we estimated the individual H−K and K−L colors for the source sample and compared the results to known cluster members. The classification revealed a noticeable contrast between the S-stars and the dusty sources. To fit the flux-density distribution, we utilized the radiative transfer code HYPERION and implemented a young stellar object Class I model. We obtained the position angle from the Keplerian fit results; additionally, we analyzed the distribution of the inclinations and the longitudes of the ascending node. Results. The colors of the dusty sources suggest a stellar nature consistent with the spectral energy distribution in the near and midinfrared domains. Furthermore, the evaporation timescales of dusty and gaseous clumps in the vicinity of SgrA* are much shorter ( 2yr) than the epochs covered by the observations (≈15yr). In addition to the strong evidence for the stellar classification of the D-sources, we also find a clear disk-like pattern following the arrangements of S-stars proposed in the literature. Furthermore, we find a global intrinsic inclination for all dusty sources of 60 ± 20◦, implying a common formation process. Conclusions. The pattern of the dusty sources manifested in the distribution of the position angles, inclinations, and longitudes of the ascending node strongly suggests two different scenarios: the main-sequence stars and the dusty stellar S-cluster sources share a common formation history or migrated with a similar formation channel in the vicinity of SgrA*. Alternatively, the gravitational influence of SgrA* in combination with a massive perturber, such as a putative intermediate mass black hole in the IRS 13 cluster, forces the dusty objects and S-stars to follow a particular orbital arrangement.

Compositions of iron-meteorite parent bodies constrainthe structure of the pr...Sérgio Sacani
Magmatic iron-meteorite parent bodies are the earliest planetesimals in the Solar System,and they preserve information about conditions and planet-forming processes in thesolar nebula. In this study, we include comprehensive elemental compositions andfractional-crystallization modeling for iron meteorites from the cores of five differenti-ated asteroids from the inner Solar System. Together with previous results of metalliccores from the outer Solar System, we conclude that asteroidal cores from the outerSolar System have smaller sizes, elevated siderophile-element abundances, and simplercrystallization processes than those from the inner Solar System. These differences arerelated to the formation locations of the parent asteroids because the solar protoplane-tary disk varied in redox conditions, elemental distributions, and dynamics at differentheliocentric distances. Using highly siderophile-element data from iron meteorites, wereconstruct the distribution of calcium-aluminum-rich inclusions (CAIs) across theprotoplanetary disk within the first million years of Solar-System history. CAIs, the firstsolids to condense in the Solar System, formed close to the Sun. They were, however,concentrated within the outer disk and depleted within the inner disk. Future modelsof the structure and evolution of the protoplanetary disk should account for this dis-tribution pattern of CAIs.

JAMES WEBB STUDY THE MASSIVE BLACK HOLE SEEDSSérgio Sacani
The pathway(s) to seeding the massive black holes (MBHs) that exist at the heart of galaxies in the present and distant Universe remains an unsolved problem. Here we categorise, describe and quantitatively discuss the formation pathways of both light and heavy seeds. We emphasise that the most recent computational models suggest that rather than a bimodal-like mass spectrum between light and heavy seeds with light at one end and heavy at the other that instead a continuum exists. Light seeds being more ubiquitous and the heavier seeds becoming less and less abundant due the rarer environmental conditions required for their formation. We therefore examine the different mechanisms that give rise to different seed mass spectrums. We show how and why the mechanisms that produce the heaviest seeds are also among the rarest events in the Universe and are hence extremely unlikely to be the seeds for the vast majority of the MBH population. We quantify, within the limits of the current large uncertainties in the seeding processes, the expected number densities of the seed mass spectrum. We argue that light seeds must be at least 103 to 105 times more numerous than heavy seeds to explain the MBH population as a whole. Based on our current understanding of the seed population this makes heavy seeds (Mseed > 103 M⊙) a significantly more likely pathway given that heavy seeds have an abundance pattern than is close to and likely in excess of 10−4 compared to light seeds. Finally, we examine the current state-of-the-art in numerical calculations and recent observations and plot a path forward for near-future advances in both domains.

Embracing Deep Variability For Reproducibility and Replicability
Abstract: Reproducibility (aka determinism in some cases) constitutes a fundamental aspect in various fields of computer science, such as floating-point computations in numerical analysis and simulation, concurrency models in parallelism, reproducible builds for third parties integration and packaging, and containerization for execution environments. These concepts, while pervasive across diverse concerns, often exhibit intricate inter-dependencies, making it challenging to achieve a comprehensive understanding. In this short and vision paper we delve into the application of software engineering techniques, specifically variability management, to systematically identify and explicit points of variability that may give rise to reproducibility issues (eg language, libraries, compiler, virtual machine, OS, environment variables, etc). The primary objectives are: i) gaining insights into the variability layers and their possible interactions, ii) capturing and documenting configurations for the sake of reproducibility, and iii) exploring diverse configurations to replicate, and hence validate and ensure the robustness of results. By adopting these methodologies, we aim to address the complexities associated with reproducibility and replicability in modern software systems and environments, facilitating a more comprehensive and nuanced perspective on these critical aspects.

Anti-Universe And Emergent Gravity and the Dark UniverseSérgio Sacani
Recent theoretical progress indicates that spacetime and gravity emerge together from the entanglement structure of an underlying microscopic theory. These ideas are best understood in Anti-de Sitter space, where they rely on the area law for entanglement entropy. The extension to de Sitter space requires taking into account the entropy and temperature associated with the cosmological horizon. Using insights from string theory, black hole physics and quantum information theory we argue that the positive dark energy leads to a thermal volume law contribution to the entropy that overtakes the area law precisely at the cosmological horizon. Due to the competition between area and volume law entanglement the microscopic de Sitter states do not thermalise at sub-Hubble scales: they exhibit memory effects in the form of an entropy displacement caused by matter. The emergent laws of gravity contain an additional ‘dark’ gravitational force describing the ‘elastic’ response due to the entropy displacement. We derive an estimate of the strength of this extra force in terms of the baryonic mass, Newton’s constant and the Hubble acceleration scale a0 = cH0, and provide evidence for the fact that this additional ‘dark gravity force’ explains the observed phenomena in galaxies and clusters currently attributed to dark matter.
SDSS1335+0728: The awakening of a ∼ 106M⊙ black hole⋆Sérgio Sacani
Context. The early-type galaxy SDSS J133519.91+072807.4 (hereafter SDSS1335+0728), which had exhibited no prior optical variations during the preceding two decades, began showing significant nuclear variability in the Zwicky Transient Facility (ZTF) alert stream from December 2019 (as ZTF19acnskyy). This variability behaviour, coupled with the host-galaxy properties, suggests that SDSS1335+0728 hosts a ∼ 106M⊙ black hole (BH) that is currently in the process of ‘turning on’. Aims. We present a multi-wavelength photometric analysis and spectroscopic follow-up performed with the aim of better understanding the origin of the nuclear variations detected in SDSS1335+0728. Methods. We used archival photometry (from WISE, 2MASS, SDSS, GALEX, eROSITA) and spectroscopic data (from SDSS and LAMOST) to study the state of SDSS1335+0728 prior to December 2019, and new observations from Swift, SOAR/Goodman, VLT/X-shooter, and Keck/LRIS taken after its turn-on to characterise its current state. We analysed the variability of SDSS1335+0728 in the X-ray/UV/optical/mid-infrared range, modelled its spectral energy distribution prior to and after December 2019, and studied the evolution of its UV/optical spectra. Results. From our multi-wavelength photometric analysis, we find that: (a) since 2021, the UV flux (from Swift/UVOT observations) is four times brighter than the flux reported by GALEX in 2004; (b) since June 2022, the mid-infrared flux has risen more than two times, and the W1−W2 WISE colour has become redder; and (c) since February 2024, the source has begun showing X-ray emission. From our spectroscopic follow-up, we see that (i) the narrow emission line ratios are now consistent with a more energetic ionising continuum; (ii) broad emission lines are not detected; and (iii) the [OIII] line increased its flux ∼ 3.6 years after the first ZTF alert, which implies a relatively compact narrow-line-emitting region. Conclusions. We conclude that the variations observed in SDSS1335+0728 could be either explained by a ∼ 106M⊙ AGN that is just turning on or by an exotic tidal disruption event (TDE). If the former is true, SDSS1335+0728 is one of the strongest cases of an AGNobserved in the process of activating. If the latter were found to be the case, it would correspond to the longest and faintest TDE ever observed (or another class of still unknown nuclear transient). Future observations of SDSS1335+0728 are crucial to further understand its behaviour. Key words. galaxies: active– accretion, accretion discs– galaxies: individual: SDSS J133519.91+072807.4

Signatures of wave erosion in Titan’s coastsSérgio Sacani
The shorelines of Titan’s hydrocarbon seas trace flooded erosional landforms such as river valleys; however, it isunclear whether coastal erosion has subsequently altered these shorelines. Spacecraft observations and theo-retical models suggest that wind may cause waves to form on Titan’s seas, potentially driving coastal erosion,but the observational evidence of waves is indirect, and the processes affecting shoreline evolution on Titanremain unknown. No widely accepted framework exists for using shoreline morphology to quantitatively dis-cern coastal erosion mechanisms, even on Earth, where the dominant mechanisms are known. We combinelandscape evolution models with measurements of shoreline shape on Earth to characterize how differentcoastal erosion mechanisms affect shoreline morphology. Applying this framework to Titan, we find that theshorelines of Titan’s seas are most consistent with flooded landscapes that subsequently have been eroded bywaves, rather than a uniform erosional process or no coastal erosion, particularly if wave growth saturates atfetch lengths of tens of kilometers.

What is Context?
“Any information that can be
used to characterize the
situation of an entity. An entity is
a person, place, or object that is
considered relevant to the
interaction between a user and
an application, including the
user and applications
themselves” (Abowd, et al.,
1999; Dey, 2001)

What is Context-Aware Security?
“Context-aware security is the use of supplemental information to
improve security decisions at the time they are made, resulting in
more accurate security decisions capable of supporting dynamic
business and IT environments” (Gartner)

The Adoption of Cloud Computing
Many users have started relying on cloud services without realizing it
Many companies have remained cautious due to security concerns
Applications and storage volumes often reside next to potentially hostile
virtual environments, leaving sensitive information at risk to theft,
unauthorized exposure or malicious manipulation
Governmental regulation presents an additional concern of significant
legal and financial consequences if data confidentiality is breached
Focused interest Experimentation Near ubiquitous use

Security Challenges in the Cloud
Top four threats identified (CSA, 2013) are:
data leakage
data loss
account hijacking
insecure APIs
The OWASP foundation has categorized the database-related
attacks as the most critical ones
These attacks were responsible for 83% of the total records stolen
The most critical part of a
modern cloud application is the
data persistency layer and the
database itself

Commonly used access control models (Ferrari 2010) are:
Mandatory Access Control (MAC)
Discretionary Access Control (DAC)
Role-Based Access Control (RBAC)
The Attribute Based Access Control (ABAC)
9. Information Management Unit / ICCS of NTUA www.imu.iccs.gr
MAC and DAC Related Approaches
Solutions that are based on MAC access control they
involve rigid and static methods (Jürjens, 2001)
DAC models rely on access control matrices
rows and columns correspond to subjects and objects
respectively
their intersection points correspond to a set of allowed access
operations
Access control lists (ACL)
the controls are discretionary
10. Information Management Unit / ICCS of NTUA www.imu.iccs.gr
Role-Based Access Control (RBAC)
Role
a grouping mechanism for categorizing individual users (called subjects) based
on various properties (e.g. job title, user functions, responsibilities etc.).
Each subject has a role set, which consists of all the roles
that the subject has been authorized to use.
It lacks support for expressing access control conditions that refer to
the state of a system
e.g. the state of a protected resource, parameter values, date or time

Role-Based Access Control (RBAC)
Extensions included
Organization Role Base Access Control (ORBAC)
authorization is given to users depending on their role in an organization in a
given context
(Boustia & Mokhtari, 2008)
Generalized RBAC (GRBAC)
incorporates the concept of environment roles (Convington et al., 2001)
Shortcomings
proposes a domain specific environment role hierarchy, not easily extensible and manageable
in heterogeneous domains
it doesn’t support the fine-grained modelling of different data objects
Context-aware access control (CAAC)
Shortcomings
incorporate only specific types of contexts (Chandran & Joshi, 2005)
lack of fine-grained data access control (Zhang & Parashar, 2004)
inefficient inferring of context (Kayes et al., 2013)
12. Information Management Unit / ICCS of NTUA www.imu.iccs.gr
ABAC Related Approaches
Authorization to perform operations is determined by
evaluating attributes associated with the subject, object,
requested operations, and environment conditions
Key difference
It can express a complex Boolean rule set that can evaluate
many different attributes
e.g. OASIS eXtensible Access Control Markup Language (XACML)
declarative access control policies encouraging the separation of the access
decision from the point of use
Location-aware access control (LAAC)

Policy Modeling
Provide a set of unambiguous rules
which are interpreted by enforcement mechanisms and which
constrain the behaviour of the entities.
There is lack of proper separation of concerns (Kourtesis
and Paraskakis, 2012)
The policy definition and policy enforcement are entangled in the
implementation of a single software component, leading to the
lack of
portability
explicit representation of policy relationships
15. Information Management Unit / ICCS of NTUA www.imu.iccs.gr
Policy Modeling
Syntactic Policy Description
promotes a declarative approach to policy expression,
where access rules are encoded imperatively, as part of the same
software that checks for their compliance.
RuleML, XACML, WS-Trust
fail to capture the knowledge lurking behind policies
any interoperability relies on the use of vocabularies that are shared
among all parties involved in an interaction.
leads to ad-hoc reasoning about policy compliance
limits the reusability and portability of policies
precludes the identification of inter-policy relations
limits the ability to perform policy governance
16. Information Management Unit / ICCS of NTUA www.imu.iccs.gr
Policy Modeling
Semantically-rich Policy Description
employs ontologies in order to assign meaning to actors, actions
and resources
ability to reason about policy compliance generically
identification of inter-policy relations such as inconsistent policies, and
overlapping policies
portability, visibility, and reusability of policies
facilitates policy governance
