Abstract: Improved approaches for providing secure access to resources maintained on private networks are disclosed. The secure access can be provided through a public network using a standard network browser. Multiple remote users are able to gain restricted and controlled access to at least portions of a private network through a common access point. The solution provided by the invention is not only easily set up and managed, but also able to support many remote users in a cost-effective manner.

Abstract: A device may receive a data unit at a line interface of a network device, convey the data unit to a first component in the line interface, update a flow table in the first component based on the data unit, send a message to a second component in the network device, the message describing the update to the flow table, and forward the data unit from the first component to another line interface in the network device.

Abstract: A system and method for intrusion detection and prevention processing are described. One or more states of a finite state automaton (FSA) stored in a memory may be compressed to form compressed state information. The FSA may include a set of states and defined state transitions for input characters. The compressed state information may include individual entries for the characters having a corresponding state transition to a next state, and a single entry for the values having a corresponding state transition to a common state. Context data may be searched using the compressed state information.
