A service-centric approach to access control and monitoring based on distributed trust
A service-oriented approach to dynamic refinement
of security enforcement is described in this
paper. This is based on a closed loop feedback
system where live distributed trust measures are
used to adapt access control settings in a changing
threat environment. A general trust overlay architecture
and model are presented. Some specific
application scenarios are discussed, in particular
spam filtering and distributed intrusion detection
in mobile ad hoc networks. It is shown using
simulations of some specific scenarios that this
dynamic system is robust and has the potential to
enhance security and access control efficiency
