Which of the following is a possible effective strategy to address physical access to company facilities?

• A. Require visitors to sign in and out
• B. Post warning signs
• C. Hire security guards
• D. Install CCTV at entrances

Answer: (A)

Controlling who can enter a building is a basic step in preventing workplace violence, and requiring visitors to sign in and out is a foundational, effective method. It creates a verifiable record of every person on site, including who invited them and when they arrive and leave. This log supports authorization verification, can trigger escorts for unfamiliar or high-risk visitors, and enables rapid, accurate responses during incidents or emergencies. While other measures add layers of security, they don’t alone establish active entry control: warning signs raise awareness but don’t restrict entry, a security presence can be costly and still relies on a process to verify approval, and CCTV monitors activity but does not prevent unauthorized access by itself. So, a clear sign-in/sign-out process provides practical, auditable control over physical access.
