Which of these is not a good practice for physical security?

Permitting visitors access to all areas of a facility undermines security protocols and poses risks to sensitive information and assets. In a secure environment, it's vital to restrict access to only those individuals who have a legitimate need to enter specific areas. This practice helps to prevent unauthorized access and protect both physical assets and confidential information from potential threats. Effective physical security measures focus on controlling who can enter sensitive areas and maintaining strict access protocols. By ensuring that only authorized personnel are allowed in restricted areas, an organization significantly enhances its security posture and reduces vulnerabilities.
