Despite its potential to tackle many security challenges of large-scale systems such as pervasive networks, self-managed protection has been little explored. This paper addresses the problem from a policy management perspective by presenting a policy-driven framework for self-protection of pervasive systems called ASPF (Autonomic Security Policy Framework). Enforced authorization policies in a device are adapted according to the security context, both at the network and device levels. ASPF describes how an autonomic security manager may control OS-level authorization mechanisms supporting multiple classes of policies. Evaluation of an ASPF implementation shows that the framework enables effective self-protection of pervasive systems.
