Linux Security Modules (LSM)
Linux Security Modules (LSM) are a framework within the Linux operating system that enables the integration of various security policies and mechanisms. They allow developers to implement different security modules—like SELinux or AppArmor—that control and restrict how programs and users access system resources. Think of LSM as a customizable security gatekeeper, providing flexible and granular control over system security without altering the core Linux kernel, ensuring that the system remains secure while allowing tailored protection based on specific requirements.
