Enhancing Mediation Security by Aspect-Oriented Approach
نویسندگان
چکیده
Research on mediation techniques to integrate data from heterogeneous data sources has made comprehensive progress. However, mediation poses extensive security problems. Protecting proprietary data from unauthorized access is recognized as one of the most significant barriers to the mediation systems. Neither traditional access control methods are adequate to model the flexible access control requirements, nor are they amenable to manage the evolvable security features of mediation systems. This paper addresses to enhancing mediation security by aspect-oriented approach. The basic functionality components and security concerns are separated, independently specified, and then systematically integrated into a unified model. Our approach benefits in both decreasing design complexity of mediation systems and increasing flexibility and dependability of security enforcement.

Dwarf Frankenstein is still in your memory: tiny code reuse attacks
Code reuse attacks such as return oriented programming and jump oriented programming are the most popular exploitation methods among attackers. A large number of practical and non-practical defenses are proposed that differ in their overhead, the source code requirement, detection rate and implementation dependencies. However, a usual aspect among these methods is consideration of the common be...
متن کاملApplying Aspect-Orientation in Designing Security Systems: A Case Study
As a security policy model evolves, the design of security systems using that model could become increasingly complicated. It is necessary to come up with an approach to guide the development, reuse and evolution of the design. In this paper, we propose an aspect-oriented design approach to designing flexible and extensible security systems. A case study demonstrates that such an approach has m...
متن کاملArchitecting Secure Software Systems Using an Aspect-Oriented Approach: : A Survey of Current Research
The importance of security in the development of complex software systems has increasingly become more critical as software becomes increasingly more pervasive in our everyday lives. Aspect-orientation has been proposed as a means to handle the crosscutting nature of security requirements when developing, designing and implementing security-critical applications. This paper surveys some of the ...

An Aspect-Oriented Framework for Systematic Security Hardening of Software Azzam Mourad, Ph.D. Concordia University, 2008 In this thesis, we address the problems related to the security hardening of open source software. Accordingly, we first propose an aspect-oriented and pattern-based approach for systematic security hardening. It is based on the full separation between the roles and duties o...

Affecting multiple parts in software systems, security requirements often tangle with functional requirements. In order to separate crosscutting concerns and increase modularity, we propose to represent security requirements as aspects that can be woven into functional requirements. Using problem frames to model the functional requirements, weaving is achieved by composing the modules represent...
