Advanced evasion techniques can bypass network security

After "APT", we now have "AET"

A new hacking technique creates a mechanism for hackers to smuggle attacks past security defences, such as firewalls and intrusion prevention systems.

So-called advanced evasion techniques (AET) are capable of bypassing network security defences, according to net appliance security firm Stonesoft, which was the first to document the approach. Researchers at the Finnish firm came across the attack while testing its security appliance against the latest hacker exploits.

Various evasion techniques including splicing and fragmentation have existed for years. Security devices have to normalise traffic using these approaches before they can inspect payloads and block attacks.
