Description: The ‘Active Enforcement’ refers to a mode in which SELinux (Security-Enhanced Linux) actively enforces the security policies defined in a Linux-based operating system. This approach focuses on implementing mandatory access controls, meaning that decisions about access to system resources are not solely dependent on user permissions but are governed by predefined security policies. In this mode, SELinux monitors and restricts the actions of processes in real-time, ensuring that only permitted operations are performed. This provides an additional layer of security, protecting the system against vulnerabilities and attacks, even if an attacker manages to gain user privileges. ‘Active Enforcement’ is crucial for maintaining the integrity and confidentiality of data, as it limits the potential damage that malicious software or human error can cause. Additionally, it allows system administrators to have more granular control over the behavior of applications and services, facilitating auditing and compliance with security regulations. In summary, SELinux’s ‘Active Enforcement’ is a powerful tool for managing security in operating systems, providing robust defense against internal and external threats.
