According to regulations, which option is most accurate in regard to Security control measures?

Integrated systems are necessary to ensure complete security because they provide a comprehensive approach to safeguarding sensitive information and facilities. Such systems combine various security measures, including physical barriers, electronic surveillance, access control technologies, and monitoring procedures. This multi-layered approach enhances the overall effectiveness of a security program, allowing for better detection of unauthorized access attempts and facilitating quicker responses to potential security breaches.

Relying solely on locking doors would not account for potential vulnerabilities, such as unauthorized access through windows or other entry points. Manual observation of entrances, while it has its uses, may not always be feasible or comprehensive enough to cover all potential threats, especially in larger facilities. Lastly, periodic checks alone do not provide the continuous monitoring necessary to detect and respond to security incidents in real-time, which integrated systems are designed to do effectively.
