What are techniques used by security personnel to deter terrorism?

The correct answer focuses on the four essential techniques: Deter, Delay, Deny, and Detect. Each of these techniques plays a critical role in a comprehensive security strategy aimed at preventing acts of terrorism.

1. Deter: This involves measures taken to discourage potential terrorist acts through visible security presence and effective communication of consequences. By making it clear that security personnel are vigilant and prepared, the likelihood of an attack can be significantly reduced.

2. Delay: This technique aims to buy time in the event of an attempted attack. By implementing barriers, checkpoints, and controlled access points, the response forces have time to react and intervene before any harm can be done.

3. Deny: Denial refers to restricting access to target areas or resources that terrorists might seek to exploit. This can be accomplished through physical security measures, such as fences, surveillance systems, and restricted access protocols.

4. Detect: This technique emphasizes the importance of identifying suspicious activities or individuals through surveillance and intelligence gathering. Early detection of potential threats allows security personnel to respond appropriately before a situation escalates.

These elements are fundamental to developing an effective security strategy against terrorism, making this combination the most appropriate answer. The options presented in the other choices
