Discuss the difference between physical security and personnel security.
What will be an ideal response?
Physical security is synonymous with "controlling physical access" and should be carefully monitored for any equipment that is important to your computer or network security, or that could compromise that security. This means locking up such gear in equipment rooms or wiring closets (and being sure that ventilation and power supplies are adequate) to prevent the unauthorized from gaining access. It might also mean checking visitors, using ID badges, or even using special card-key locks to permit only certain authorized users to access equipment.
The best passwords and access controls in the world are worthless unless you also train staff how to maintain personnel security. When passwords are too hard to remember and there is no security policy to forbid such behavior, it's typical for people to tack notes on their terminals with their passwords for all to see (and use). It's important to formulate a security policy for your organization, make sure employees follow that policy, and avoid forms of laziness and "cheating" that can undo the best physical and software security measures.
