In view of physical security, which is a measure necessary to protect facilities against theft?

Implementing security protocols is essential for protecting facilities against theft because it establishes a systematic approach to safeguard assets and ensure a secure environment. These protocols can include measures such as access control systems, surveillance cameras, alarm systems, and regular security audits. By creating clearly defined procedures for monitoring and controlling access to a facility, the risk of theft can be significantly reduced.

Security protocols also provide guidelines for employees on how to respond in case of suspicious activity or security breaches. By effectively training staff and setting up clear rules for securing sensitive areas, businesses can deter theft and enhance overall security.

The other options, while beneficial in their own contexts, do not directly address the immediate needs for theft prevention in a physical security framework. Conducting surveys might help assess security needs but does not itself constitute a protective measure. Hiring additional sales staff or increasing customer engagement can improve business operations but does not effectively address security challenges. Therefore, the implementation of security protocols serves as the most direct and effective measure for safeguarding facilities against theft.
