Towards a Full Support of Obligations in XACML,tensible Access Control Markup Language) proposes a conceptual architecture and a policy language to reflect this ideal design of policy-based systems.However, while rights are well-captured by authorizations, duties, also called obligations, are not well managed by XACML architecture. The current v

The attempts to create decentralized OSNs (DOSNs) enable each member of an OSN keeps its own data under its control, instead of surrendering it to a central place; providing its own access-control policy.

Two-Level Automated Approach for Defending Against Obfuscated Zero-Day Attacks,bination of anomaly, behavior and signature based techniques for detecting such zero-day attacks. The proposed approach detects obfuscated zero-day attacks with two-level evaluation, generates a new signature automatically and updates other sensors by using push technology via global hotfix feature.

Towards a Full Support of Obligations in XACML,he history of obligations fulfillment/violation. In this work, we propose an extension of XACML reference model that integrates obligation states in the decision making process. We have extended XACML language and architecture for a better obligations support and have shown how obligations are managed in our proposed extended XACML architecture: .

ISER: A Platform for Security Interoperability of Multi-source Systems,order to (1) provide a secure virtualization of guests system, (2) create, model and manage systems secure interoperability, (3) verify the security policies and (4) monitor the system behavior. A case study is presented to illustrate the application of the platform.
