Definition
Enforcement refers to the implementation of rules, policies, or controls to ensure compliance and maintain desired system states. It involves mechanisms that actively monitor and react to deviations from established standards, thereby preventing unauthorized actions or configurations. This process is critical for maintaining security, integrity, and operational efficiency within an IT environment. For instance, a firewall enforces network access policies by blocking traffic that does not meet predefined criteria. Enforcement differs from mere policy definition by actively enforcing those rules rather than just stating them. This concept is frequently tested in security domains such as CompTIA Security+ and CISSP.
