Upon completing a penetration test, you identified that while extensive surveillance covered the perimeter of the server room, the individual server cabinets were not independently monitored. Additionally, entry to the server room was secured using a keyless entry pad. Which of the following recommendations in your report would best improve the physical security of the server infrastructure?
Recommend the implementation of biometric verification for both the server room entry and individual cabinet locks.
Suggest the installation of additional internal surveillance devices focused on each cabinet.
Propose coupling the entry mechanism with an alert system that notifies security personnel when access is granted.
Advise extending the complexity of the access code required on the entry pad.
