Networking communication protocols make it possible for the Internet to work. Unfortunately, criminals can use those trusted systems to obfuscate malicious data and penetrate your network defenses undetected. An advanced evasion technique (AET) is a method of delivering an exploit or malicious content into a vulnerable target so that the traffic looks normal and security devices will pass it through. By combining attacks using several protocol layers, these advanced evasions bypass most existing security solutions. Forcepoint NGFW (Next-Generation Firewall) applies sophisticated analysis techniques specifically to detect this type of attack.
