VerifiedUnderstanding Cyber Threats, IoCs, and Attack Methodology

Which technique protects against flooding attacks that originate from valid prefixes (IP addresses), so that the attacks can be traced to their actual source?

Explanation

Egress filtering validates source IP addresses on outbound traffic against the prefixes legitimately assigned to the network. It prevents attackers from sending spoofed-source flooding traffic, preserving source-address accountability and enabling traceback to the true originating network.
