Abstract
Methods and apparatus, including computer program products, implementing and using techniques for processing a data packet in a packet forwarding device. A data packet is received. A virtual local area network destination is determined for the received data packet, and a set of rules associated with the virtual local area network destination is identified. The rules are applied to the data packet. If a virtual local area network destination has been determined for the received data packet, the data packet is output to the destination, using the result from the application of the rules. If no destination has been determined, the data packet is dropped. A security system for partitioning security system resources into a plurality of separate security domains that are configurable to enforce one or more policies and to allocate security system resources to the one or more security domains, is also described.
