Preventive controls are specifically designed to stop security issues from occurring in the first place. They focus on mitigating risks before they lead to an incident or breach. Examples of preventive controls include firewalls, access controls, and application security measures, which are implemented to prevent unauthorized access or to stop harmful actions before they can affect the system.

Understanding the purpose of preventive controls is crucial for building a strong cybersecurity strategy, as these controls create barriers against potential threats and vulnerabilities from the outset. This proactive approach is essential for maintaining the integrity, confidentiality, and availability of information systems.

In contrast, detective controls are designed to identify and detect security breaches as they occur, while corrective controls aim to remedy issues after they have happened. Deterrent controls serve to discourage potential attackers through measures such as warnings or visible security features, but they do not actively stop an issue from happening. In summary, preventive controls are the first line of defense in preventing security incidents proactively.
