Which of the following controls can help deter unauthorized access to a facility?

Surveillance cameras are an effective control measure for deterring unauthorized access to a facility. By installing cameras, organizations create a visible deterrent that can discourage potential intruders from attempting to gain unauthorized entry. The presence of surveillance not only helps to monitor activity but also provides valuable evidence that can be used in investigations or to address security breaches if they occur.

In addition to acting as a deterrent, surveillance cameras can enhance overall security by allowing security personnel to observe activities in real-time or review recorded footage after an incident. This ability to monitor and document behaviors aids in maintaining a secure environment and ensuring compliance with security protocols.

Employee training programs are essential for raising awareness about security practices but do not have a direct physical deterrent effect. Updated software protocols mainly focus on data security rather than physical access control, while regular audits are vital for assessing security practices but do not actively prevent unauthorized access.
