Which of the following describes a proactive measure in physical security?

The choice of regularly updating security protocols is a prime example of a proactive measure in physical security. Proactive measures focus on anticipating potential threats and taking steps to mitigate risks before any incidents can occur. By continuously reviewing and enhancing security protocols, organizations can adapt to new vulnerabilities, technological advancements, and evolving threat landscapes. This forward-thinking approach helps create a more robust security environment, reducing the likelihood of incidents occurring in the first place.

In contrast, waiting for incidents to occur or only securing areas when incidents happen represents reactive measures, which involve responding to security breaches after they have happened. Documenting past security breaches, while valuable for learning and improving future security strategies, does not actively prevent incidents and is thus not a proactive measure on its own. These considerations underscore the importance of maintaining an agile and continuously improving security strategy, which is encapsulated by the choice of regularly updating security protocols.
