Which statement is true about the physical security of a forensics lab?

• A. There should be multiple entrances to a forensics lab
• B. There should be no entrances to a forensics lab
• C. Physical security is not important for a forensics lab
• D. There should be only one entrance to a forensics lab

Answer: (D)

Controlling who can enter a forensics lab is essential to protect evidence, preserve its integrity, and maintain a reliable chain of custody. Having a single, controlled entrance makes it feasible to enforce strict access controls, log every entry, and monitor who and what goes in and out. With one main entry, security measures such as badge access, screening, and video surveillance can be concentrated at one point, making breaches easier to detect and respond to and reducing opportunities for unauthorized access or tampering. Multiple entrances increase the attack surface and can create blind spots where individuals or materials could bypass controls. While entrances must be practical, no entrances isn’t feasible, so a single, well-secured entry is the best practice to balance security with operational needs.
