Which type of control is implemented to prevent security breaches?

Preventive controls are specifically designed to thwart potential security breaches before they occur. These controls aim to reduce the likelihood of a security event by addressing vulnerabilities and establishing safeguards. Examples of preventive controls include firewalls, access control lists, encryption protocols, and security awareness training for employees. By implementing these measures, organizations can significantly diminish the risk of unauthorized access and other security threats.

In this context, preventive controls are distinct from other types, such as corrective controls, which address issues after a breach has occurred, and detective controls that identify security events after they happen. Compensative controls, while also serving a purpose in mitigating risks, are typically used as substitutes when primary controls cannot be implemented. Preventive controls take proactive measures to secure systems and data, making them essential for effective security management.
