Access Control

Access control policies describe the rights that different users have on the resources available and are used to protect systems against attacks by unauthorised users. Many authorisation and access control models have been proposed so far; we focus mainly on category-based access control. Amongst the most important issues that have to be addressed in this area are the development of techniques and tools for the analysis and verification of access control policies, and the design of transparent and efficient mechanisms to enforce access control policies.
