Advanced Evasion Technique (AET) is a term from information security in which attacks
on the security systems are not detected. It is an obfuscation technique consisting of various evasion methods combined together. An AET code is not necessarily malicious. The danger of AET attacks is that
theattacker can gain access to a network
without being detected byIDS or IPS systems
. AET evasion techniques use word creations composed of individual words, each of which does not provide system access on its own.
For example, if the words "money" and "move" are not allowed by an intrusion detection system (IDS), the word creation "scheliebldveren" could be used to provide access.
