The chief executive officer (CEO) of an organization asked you to audit the physical security of their building. You noticed that individuals could move freely about the building. An individual who does not work at the building was able to take a document off the CEO’s desk and walk out the door. In your report, what physical security measure could prevent this from happening again?

In order to prevent unauthorized individuals from freely moving about the building and accessing sensitive documents, the following physical security measures could be recommended in the report:

1. Access Control Systems: Implementing access control systems can restrict entry into the building and specific areas. This could include electronic key card systems, biometric scanners, or PIN-based entry systems. Only authorized employees with valid credentials should be granted access.

2. Security Guards/Reception Desk: Assigning security guards or utilizing a staffed reception desk can provide a first line of defense against unauthorized entry. They can monitor visitors, verify identities, and keep track of individuals entering and leaving the building.

3. Visitor Management System: Implementing a visitor management system can ensure all visitors are properly identified and supervised during their stay. This could involve issuing visitor badges or passes that need to be returned upon exit, and having visitors accompanied by authorized staff at all times.

4. Secure Document Storage: Implementing secure storage solutions such as locked cabinets, safes, or file rooms can protect sensitive documents. These should only be accessible to authorized personnel, preferably through individual locked compartments or cabinets.

5. Surveillance Cameras: Installing a comprehensive network of surveillance cameras in key areas of the building can act as both a deterrent and a means of capturing evidence. Positioning cameras at entrance/exit points, hallways, and sensitive areas, including the CEO's office, can aid in monitoring and recording any suspicious activity.

6. Alarms and Intrusion Detection Systems: Install burglar alarms and intrusion detection systems to promptly alert security personnel in case of unauthorized access or break-ins. These systems can include motion sensors, glass break detectors, or door and window sensors, triggering immediate notifications.

7. Regular Security Training and Awareness: Conduct frequent security training sessions to educate employees on the importance of physical security measures and the role they play in protecting sensitive information. This can include protocols for securing documents, identifying suspicious individuals, and reporting any security-related concerns.

Including these recommendations in the report will help improve the physical security of the building and mitigate the risk of unauthorized access and document theft in the future.
