On Security Policy Migrations [PDF]

Proceedings of the 25th ACM Symposium on Access Control Models and Technologies, 2020
There has been over the past decade a rapid change towards computational environments that are comprised of large and diverse sets of devices, many of them mobile, which can connect in flexible and context-dependent ways. Examples range from networks where we can have communications between powerful cloud centers, to the myriad of simple sensor devices

On Quantitative Security Policies [PDF]

, 2011
We introduce a formal framework to specify and enforce quantitative security policies. The framework consists of: (i) a stochastic process calculus to express the measurable space of computations in terms of Continuous Time Markov Chains; (ii) a stochastic modal logic (a variant of CSL) to represent the bound constraints on execution speed; (iii) two ...

Adaptive Security Policies [PDF]

, 2020
We develop an approach to security of adaptive agents that is based on respecting the local security policies of agents rather than imposing a global security policy on all agents. In short, an agent can be assured, that it will not be able to observe any violation of its own security policy due to the changing presence of other agents in its ...

Distributed security policy conformance [PDF]

Computers & Security, 2011
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 ...

, 2007
The articulation of international and transnational terrorism as a key issue in US security policy, as a result of the 9/11 attacks, has not only led to a policy rethink, it has also included a bureaucratic shift within the US, showing a re-thinking of ...
