egress filtering

Unlike ingress filtering, which scans incoming data packets for suspicious data, egress filtering is concerned with monitoring data packets leaving the network. Data packets that do not meet certain security requirements are blocked in egress filtering.

Egress filtering works like a packet filter that filters out suspicious bit patterns.

Egress filtering is an output filtering. It takes place in the edge components ofnetworks, such as in the edge router or in a firewall. It prevents malware from leaking out of a network and causing security problems. In addition, egress filtering can be used to restrict traffic from specific servers in a company or research institution.
