Known as Control Flow Enforcement Technology, or CET, the protections are designed to prevent miscreants from exploiting certain programming bugs to execute malicious code that infects systems with malware, steals data, spies on victims, and so on.

There are various mitigations in place on modern systems, such as Data Execution Prevention, that stop hackers from injecting and executing malicious code into a program when a victim opens a specially crafted document or connects to a remote service.

DEP in particular prevents areas of memory marked as data areas, which can be hijacked by hackers, from being used to run smuggled-in code.

Thus if exploit code hijacks the flow of code in an application or server, and makes it jump to someplace the developers didn't intend, this is caught and stopped.

"What ends up happening is, as the processor is jumping through the code, it checks to make sure it is landing on an end branch," said Garrison, describing Intel's anti-COP-JOP protection.
