Abstract
A solution for dynamic packet filtering includes, at a network device, if an n-tuple of a packet matches an n-tuple filter, applying an action of the filter to the packet. If the packet has not been discarded as a result of the filter application, and if the packet is identified, by using payload portion, as a network application associated with a filter policy, an n-tuple filter is generated based on the packet. If the application ID of the packet is not associated with a filter policy, the packet is forwarded to the network application.
