The increasing popularity of peer to peer groups and the decentralized nature evolve the groups towards dynamism and self-organization. Dynamic groups like Wikipedia, F/OSS and other business communities motivate the need for dynamic multilevel access control. These self-organizing groups have special security requirements out of which Access Control mechanism is one of the essential security factors. Policy based access control mechanism is helpful in providing dynamism to the overall access control. The dynamic nature of peers joining and leaving and changing environment, increases the possibility of presence of malicious peers. To enable a group to survive one needs to tackle impact of malicious peers on the group performance. Paper includes a brief work on dynamic policy based access control and dynamic control on malicious peers. Simulation of the work is done in Peersim integrated with Prolog to test the framework in presence of static and dynamic access control.
