Distributed security policy conformance

Distributed Security Policy Conformance

Security policy conformance is a crucial issue in large-scale critical cyber-infrastructure. The complexity of these systems, insider attacks, and the possible speed of an attack on a system necessitate an automated approach to assure a basic level of protection. This paper presents Odessa, a resilient system for monitoring and validating compliance of networked systems to complex policies. To ...

Distributed Monitoring in Ad Hoc Networks: Conformance and Security Checking

Ad hoc networks are exposed more than traditional networks to security threats due to their mobility and open architecture aspects. In addition, any dysfunction due to badly con gured nodes can severely a ect the network as all nodes participate in the routing task. For these reasons, it is important to check the validity of ad hoc protocols, to verify whether the running implementation is conf...

Distributed Contingency Logic and Security

In information security, ignorance is not bliss. It is always stated that hiding the protocols (let the other be ignorant about it) does not increase the security of organizations. However, there are cases that ignorance creates protocols. In this paper, we propose distributed contingency logic, a proper extension of contingency (ignorance) logic. Intuitively, a formula is distributed contingen...

Multilevel Policy Based Security in Distributed Database

Addressing security demands under fixed budgets and deadline constraints are becoming extremely challenging, time consuming and resource intensive. Moreover, securing the distributed database in compliance with several security guidelines makes the system more complex. Mission critical systems, military, government and financial institutions have been under tremendous pressure to secure their d...
