EMET (Enhanced Mitigation Experience Toolkit) is an application which can be used to further harden a Windows system by adding additional security protections to running processes. These protections include several ROP (Return-Oriented-Programming) checks, shellcode detection mechansims, heap-spray mitigations and many more.
The talk covers techniques to bypass EMET 5.1 (the current version) and shows the audience how hard/easy it is for an attacker to accomplish this.
