A method and system allows for the deployment of security policies into the higher layers of the OSI model. Specifically, it allows for the establishment of security policies at layer 4 and higher, by monitoring authentication flows and using these flows as the basis for establishing security policies which then can be used as a basis for assessing the operation of the network.

Method and system for authentication event security policy generation

Technique for protecting a communications network, such a computer network, from attack such as self-propagating code violations of security policies, in which the network is divided into 'compartments' that are separated by access control devices such as firewalls. The access control devices are then used to stop the spread of self-propagating attack code, the 'zero-day' worms, for example. However, the access control devices are configured such that upon activation legitimate in-use network services will not be jeopardized.
