Final answer:
At a minimum, a security system should include a set of comprehensive elements such as guard orders, access controls, barriers, lighting, locks, and Intrusion Detection Systems (IDS), with an emphasis on advanced monitoring like drone technology for enhanced protection.
Step-by-step explanation:
At a minimum, a well-structured security system should include special and general guard orders, access and material control, protective barriers, lighting systems, locks, and Intrusion Detection Systems (IDS). These elements form the core of a security infrastructure designed to protect facilities, like airports, from unauthorized access or damage. For instance, security gates at airports are technological marvels that not only detect metals but can also pinpoint their approximate height above the floor, as depicted in Figures 14.9 and 23.43. In response to increasing security challenges, there is a growing emphasis on 24-hour monitoring efforts potentially enhanced by drone technology, according to discussions by Isla and other experts in the field.
This comprehensive monitoring is crucial for sites of importance to prevent unwarranted human incursions and ensure overall safety. Additionally, the consideration of control elements such as a shield and containment system can further bolster a site's defenses. By integrating these components effectively, organizations can establish a formidable security posture to deter, detect, and respond to various threats.
