Memory integrity, a security feature in operating systems, is designed to protect the integrity of memory from malicious actors and software. It helps prevent unauthorized changes or modifications to critical system memory, which could potentially lead to system instability, crashes, or unauthorized access to sensitive data.
Memory integrity typically works by utilizing hardware-enforced mechanisms such as hardware-based memory protections, like Intel's Control-Flow Enforcement Technology (CET) or Windows Defender Application Guard (WDAG). These mechanisms help to prevent attackers from exploiting vulnerabilities in the system to manipulate or corrupt memory.
By enforcing memory integrity, the operating system can ensure that only legitimate, trusted processes are allowed to access and manipulate system memory. This helps to protect critical system components and sensitive data from unauthorized access or tampering.
Overall, memory integrity is an important security feature that helps to enhance the overall security posture of a system by preventing memory-based attacks and ensuring the integrity of system memory.
