OS Guard

Intel OS Guard is a security feature that is included in some newer Intel processors. It is designed to help protect the operating system (OS) against certain types of attacks that attempt to exploit vulnerabilities in the OS kernel or other critical system components.

Specifically, Intel OS Guard provides hardware-based protection against certain types of privilege escalation attacks, such as return-oriented programming (ROP) and jump-oriented programming (JOP) attacks. These types of attacks are often used by malware and other malicious software to gain elevated privileges and bypass security measures.

Intel OS Guard works by preventing certain types of instructions from being executed in user mode. This helps to prevent attackers from using ROP and JOP techniques to gain control of the OS kernel or other critical system components.

Overall, Intel OS Guard is an important security feature that can help to enhance the security and reliability of computer systems, particularly in business and enterprise environments where security threats are a significant concern. It provides an additional layer of protection against certain types of attacks that attempt to exploit vulnerabilities in the operating system, helping to ensure that sensitive data is properly protected.
