As the new security administrator, you have identified the absence of deterrent controls in your company. Which of the following options would you implement to meet your requirements?

Deterrent controls are intended to discourage potential attackers from carrying out attacks. Examples of deterrent controls include perimeter lighting and warning signs like "no trespassing." On the other hand, the remaining options are instances of detective controls. Detective controls are meant to identify violations, although some detective controls may also serve as deterrents, such as visible cameras, even though they are not primarily intended for that purpose.
