Sara is the network manager of an investment firm. She has decided to improve the physical security of the storage devices attached to her network. Which strategy would achieve her objective? a. Install video cameras in network server rooms.
b. Update virus protection software daily.
c. Complete incremental backups every night during the week to one designated drive.
d. Implement a password strength policy.

The correct answer is A. Install video cameras in network server rooms.

Explanation:

Physical security focuses on preventing any physical action or activity that can have a negative impact on a firm. This includes theft, physical destruction of goods, espionage, among others. This implies in the case presented Sara is concern about people physically entering the area where the storage devices are physically attacking the devices or extracting information. According to this, the best strategy is "Install video cameras in network server rooms" because this will prevent any physical attack by making sure only authorized people enter the area. Also, others such as "update virus protection" or "strength passwords" are useful for cybersecurity, not physical security.
