To navigate the large number of controls, organizations need guidance on configuring various security features. A system that is security hardened is in a much better position to repel these and any other innovative threats that bad actors initiate. Binary hardening often involves the non-deterministic modification of control flow and instruction addresses so as to prevent attackers from successfully reusing program code to perform exploits. In conjunction with your change management process, changes reported can be assessed, approved and either remediated or promoted to the configuration baseline.
