The assurance of network security is dependent not only on the protocols but also on polices that determine the functional behavior of network security devices. Network security devices such as Firewalls, IPSec gateways, IDS/IPS operate based on locally configured access control policies. However, the complexity of managing security polices, particularly in enterprise networks, poses many challenges for deploying effective security. For example, security policies are usually configured in isolation from each other, even though they are not necessarily independent as they interact with each other to form the global security policy.
