What is Mandatory Integrity Control designed to enhance in Windows systems?

Mandatory Integrity Control (MIC) in Windows systems is a security mechanism that enhances data integrity through access control. It operates by assigning integrity levels to processes and objects, which dictate the type of access they have relative to one another. The fundamental aim of MIC is to prevent lower-integrity processes from affecting the data or operations of higher-integrity processes, thereby preserving the overall integrity of the system.

For instance, if a process with a lower integrity level attempts to tamper with data belonging to a process with a higher integrity level, the operating system will restrict this action based on the predefined integrity levels. This layered approach ensures that sensitive data and critical system functions remain secure from potential malicious actions initiated by lesser processes, enhancing the stability and integrity of the system.

This focus on access control through integrity levels is what fundamentally distinguishes MIC, making it a key component in the defense-in-depth strategy and improving the overall security posture of Windows environments.
