The evaluation procedure for physical security typically involves assessing the effectiveness of measures such as access controls, surveillance systems, security personnel, and perimeter defenses. This often includes conducting security audits, vulnerability assessments, and penetration testing to identify weaknesses and areas for improvement. The results are then used to develop a security plan that addresses identified vulnerabilities and enhances overall protection.
