The project work explores in detail, the security issues in a SOA environment and also describes the various approaches to these issues. The different approaches to SOA security (i.e. message level security, security as a service and policy driven security) are not standalone solutions, but can be deployed as mix and match solutions. A SOA security solution can make use of all the approaches to address specific security concerns. Finally the project work describes a generic SOA security model which acts as a reference model to identify security vulnerabilities in enterprise application integration (EAI). These vulnerabilities can then be addressed by the different approaches to security.

SOA Security
This document discusses security considerations for service-oriented architectures (SOAs). It begins by defining SOA and some common SOA technologies like SOAP, WSDL, and UDDI. It then covers important security concepts like confidentiality, integrity, non-repudiation, authentication, authorization, and availability. Specific security standards and approaches are discussed for each concept, such as encryption for confidentiality and digital signatures for integrity and non-repudiation. Authentication methods like digital certificates and SAML are also described. The document advocates for defining clear security policies and separating policy enforcement from decision making. It concludes by discussing threats to XML and debates between using REST vs SOAP/WS-Security approaches.
Web Services Security Tutorial
This document provides an overview of web services security. It discusses the main concerns of authentication, authorization, confidentiality and integrity. It presents a framework for web services security and describes how security can be implemented at the transport, message and application levels. Various usage scenarios for web services are explored, and the security implications of scenarios like enterprise application integration, reusing existing business logic, and business partner collaboration are examined. Emerging standards for web services security are also overviewed.
Web Services Security - Presentation
This document discusses web service security and the EASI framework. It introduces key concepts like web services, SOAP, WSDL, and UDDI. It explains the need for web service security to protect sensitive data exchanged between businesses. The EASI framework provides a common security approach across application tiers to integrate different security solutions while allowing new technologies to be added. EASI specifies interactions between security services and applications to enforce security in a way that is transparent to unaware applications.
Soa Testing An Approach For Testing Security Aspects Of Soa Based Application
The document describes an approach for testing security aspects of service-oriented architecture (SOA) based applications. It focuses on testing specifications such as WS-Security, SAML, WS-Trust, WS-SecureConversation, and WS-Security Policy. The approach involves writing customized test assertion documents based on specifications, capturing SOAP messages at interfaces, and comparing messages to test assertions to generate test results.
Soa Security Testing
This document proposes a solution for testing the security aspects of SOA-based applications. The solution involves three phases: 1) Creating a test assertion document (TAD) that identifies the security specifications implemented, 2) Using a SOAP monitor tool to capture request and response messages, and 3) Developing code to compare the SOAP messages to the TAD and generate a test result report. The proposed approach streamlines testing, increases agility, and reduces IT investment while maximizing return on investment. Reusable artifacts are created to provide better system understanding throughout the testing lifecycle.

Security Model for Hierarchical Clustered Wireless Sensor Networks
The proposed security system for the Wireless Sensor Network (WSN) is based on the WSN security design goal that ‘to design a completely secure WSN, security must be integrated into every node of the system’. This paper discusses on two main components of the security framework viz. the secure key management module and the secure routing scheme. The incorporation of security mechanism during the routing protocol design phase is the main focus of this paper. The proposed security framework viz. ‘Secure and Hierarchical, a Routing Protocol’ (SHARP) is designed for the wireless sensor network applications which is deployed particularly for data collection purpose in a battlefield where the security aspect of the network cannot be compromised at any cost. SHARP consists of three basic integrated modules and each module performs a well defined task to make the whole security framework a complete system on its own.
A Proposed Security Model for Web Enabled Business Process Management System
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.
Security Models in Cellular Wireless Networks
- Wireless networks and cellular networks are increasingly used for sensitive data transfer, raising security concerns.

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

A man driving in one direction shouts "donkey" to a woman driving in the opposite direction. She quickly responds "monkey." They continue on their ways, with the woman feeling satisfied by her response, until she reaches a curve in the road. The story's moral suggests that women do not understand what men are trying to communicate.
Representing chemicals using OWL, Description Graphs and Rules
Objects can be said to be structured when their representation also contains their parts. While OWL in general can describe structured objects, description graphs are a recent, decidable extension to OWL which support the description of classes of structured objects whose parts are related in complex ways. Classes of chemical entities
such as molecules, ions and groups (parts of molecules) are often characterized by the way in which the constituent atoms of their instances are connected via chemical bonds. For chemoinformatics tools and applications, this internal structure is represented using chemical graphs. We here present a chemical knowledge base based on the standard chemical graph model using description graphs, OWL and rules. We include in our ontology chemical classes, groups, and molecules, together with their
structures encoded as description graphs. We show how role-safe rules can be used to determine parthood between groups and molecules based on the graph structures and to determine basic chemical properties. Finally, we investigate the scalability of the technology used through the development of an automatic utility to convert standard chemical graphs into description graphs, and converting a large number of diverse graphs obtained from a publicly available chemical database
Mining 012 riskope is it true that pi_gs
Tailings systems in mines are often the object of Risk Assessments. Unfortunately common practices in Risk Assessment, using PIGs (Probability Impact Graphs) are arbitrary, lead to confusing and fuzzy results, offer very little decision making support and misrepresent reality. After demonstrating these pitfalls, the presentation shows how to do better by using ORE (Optimum Risk Estimates), a methodology developed by Riskope.
Riskope has developed a proprietary application that allows to package ORE results into cockpits addressing top and mid-management concerns, allowing strategic integration of risks in corporate policies.

It also discusses the Network Management System (NMS) hardware and software that monitors and administers networks, providing performance, inventory and traffic information. Finally, it mentions the Management Information Base (MIB) which contains information about managed network devices that is accessible to SNMP programs.
More Edisons Needed, not Einsteins: By Nastas
The presentation discusses the need for more entrepreneurs and innovative jobs. The World Bank asked the speaker to present on scaling up entrepreneurship as countries want help increasing the number of start-ups and small-to-medium enterprises. The presentation argues that building experience with risk, failure, and uncertainty is needed to increase entrepreneurship. It provides solutions like selling the opportunity not just the risk, generating more business ideas, and establishing mentoring organizations. The overall message is that developing more "Edison-like" entrepreneurs focused on doing more, faster and cheaper can help economies participate in an increasingly knowledge-based world.

MODEL-DRIVEN SECURITY ASSESSMENT AND VERIFICATION FOR BUSINESS SERVICES
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.

F017353539
The document proposes an algorithm to secure SOAP-based web services from WSDL scanning attacks. The algorithm uses existing security standards like PKI, digital signatures, and XML encryption/decryption. It encrypts critical portions of the WSDL using symmetric encryption before publishing it to the UDDI registry. The encrypted WSDL contains a digital signature and hash to validate integrity. Clients must decrypt the WSDL using the service provider's public key before binding to prevent attacks from interpreting the WSDL contents. The algorithm was implemented and tested using Java with real banking data, with minimal performance overhead.

Web Service is a reusable component which has set of related functionalities that service requesters can
programmatically access from the service provider and manipulate through the Web. One of the main
security issue is to secure web services from the malicious requesters. Since trust plays an important role in
many kinds of human communication, it allows people to work under insecurity and with the risk of
negative cost, many researchers have proposed different trust based web services access control model to
prevent malicious requesters. In this literature review, various existing trust based web services access
control model have been studied also investigated how the concept of a trust level is used in the access
control policy of a service provider to allow service requester to access the web services

Web Services Security - Short Report
This document discusses security considerations for web services. It begins by defining key terms like web services, SOAP, WSDL, UDDI, and ebXML. It then discusses the goals of security like confidentiality, integrity, accountability and availability. Next, it covers requirements for web services security like authentication, authorization, cryptography, and accountability. It introduces the concept of Enterprise Application Security Integration (EASI) to provide a common security framework across different tiers. EASI requires perimeter security between clients and web servers, mid-tier security between application components, and back-office security for databases. The document concludes that web services should be designed according to enterprise application security architecture principles.

Malta soa infrastructure
The document discusses how service-oriented architecture (SOA) impacts IT infrastructure and introduces new considerations for performance, security, availability, service management, and virtualization. Key points include:
- SOA introduces new infrastructure components like XML gateways and introduces challenges for monitoring distributed applications and isolating performance bottlenecks.
- Security must be implemented across multiple layers to secure messages in SOA environments while propagating identities among partners.
- High availability, disaster recovery, and scalability require techniques like clustering, workload management, and data replication across SOA components.
- Service management requires monitoring all components and closing the loop between infrastructure events and business services.
- Virtualization can help decouple applications from infrastructure
HTTPI BASED WEB SERVICE SECURITY OVER SOAP
Now a days, a new family of web applications 'open applications’, are emerging (e.g., Social Networking, News and Blogging). Generally, these open applications are non-confidential. The security needs of these applications are only client/server authentication and data integrity. For securing these open applications, effectively and efficiently, HTTPI, a new transport protocol is proposed, which ensures the entire security requirements of open applications. Benefit of using the HTTPI is that it is economical in use, well-suited for cache proxies, like HTTP is, and provides security against many Internet attacks (Server Impersonation and Message Modification) like HTTPS does. In terms of performance HTTPI is very close to the HTTP, but much better than HTTPS. A Web service is a method of communication between two ends over the Internet. These web services are developed over XML and HTTP. Today, most of the open applications use web services for most of their operations. For securing these web services, security design based on HTTPI is proposed. Our work involves securing the web services over SOAP, based on the HTTPI. This secure web service might be applicable for open applications, where authentication and integrity is needed, but no confidentiality required.
In our paper, we introduce a web service security model based on HTTPI protocol over SOAP and develop a preliminary implementation of this model. We also analyze the performance of our approach through an experiment and show that our proposed approach provides higher throughput, lower average response time and lower response size than HTTPS based web service security approach.
Soa
The document discusses service oriented architecture (SOA). It defines SOA as an approach where applications use services available over a network to perform business functions. Key components of SOA include services, service types, layers, and governance patterns. SOA uses XML-based standards like SOAP, WSDL, and UDDI to allow services to communicate over different platforms. The presentation covers the basics of SOA, its benefits, and technical concepts like web services.
Security again: Web services with mule
MuleSoft provides solutions for securing web services. It allows consuming and exposing existing web services in a secured way using standards like WS-Security. The CXF module in Mule supports web service security standards and provides different solutions to secure web services above transport level, such as authentication and authorization. It implements WS-Security which defines a SOAP header to carry security tokens to identify callers and their privileges.

This document provides an overview of web services and the web services stack. It discusses key web service standards and protocols including SOAP, WSDL, UDDI, WS-Addressing, WS-Policy, WS-ReliableMessaging, and WS-Security. It also summarizes several research papers related to policy-based authorization, dynamic service composition, best practices, delegation of authority, and non-repudiation in B2B interactions using web services.
An interoperability framework for
Cloud computing is a major trend and a fast growing phenomena in the IT world. Organizations working in different sectors such as education or business are becoming more interested in moving their applications to the cloud to boost their infrastructure resources; increase their applications’ scalability and reduce costs. This boost in demand for cloud services led to the need for clouds to federate, in order to flawlessly deliver the required computation power and other services. In addition, there is major trend in delegating identity management tasks to identity providers in order to reduce cost. Managing identity and access control across different domains is a challenge. This paper proposes a framework for managing identity in federated clouds based on the use of a Security Assertion Markup Language (SAML) Agent. The agent acts as an interface for a cloud identity manager where it sends and receives identity assertion requests from and to other clouds in the federation. In addition, the agent assigns roles to users using identity attributes received in assertions and cloud’s internal role mapping rules. For testing the agent’s capability to scale and sustain load, a prototype implementation was developed. Performance evaluation results demonstrate the viability of the proposed framework.
