Security is an important QoS attribute for characterizing intrusion tolerant systems. In order to evaluate security performance of an intrusion tolerant system more effectively and directly, quantifying its security is inevitable. From the view of practical application, this paper provides a novel quantifying method. The security of intrusion tolerant systems is quantified to three explicit attributes...

Access control plays an important role for various SON applications yet most SON proposals do not consider access control or assume that it is a pre-existing service. The lack of a proper access control...
