Abstract
A method and system is disclosed for managing and implementing a plurality of network policies in a network device. Each of the plurality of policies are defined by one or more filters. The filters are installed in a policy engine. A layer identifies the network policy to be applied to a packet by sending a request to the policy engine. The policy engine then returns the policy to the requesting layer. The method and system may be used to implement a programmable, host-based, distributed, authenticating firewall that enables security and other policies to be applied at several protocol layers.
