Which practice enhances physical security capabilities?

Improving lighting in facilities directly enhances physical security capabilities by increasing visibility in and around the premises. Well-lit areas can deter potential intruders and heighten the safety of employees and visitors. Proper lighting makes it easier to monitor activities and environments and can help identify unauthorized access or suspicious behavior. This proactive measure not only boosts safety but also contributes to the overall security posture by creating a less favorable environment for nefarious activities.

In contrast, while increased employee training can foster awareness and compliance with security protocols, it does not physically alter the security infrastructure. Frequent travel assessments may evaluate risks associated with travel but do not directly improve the physical environment. Regular personnel turnover could introduce security risks rather than enhance physical security, as it may lead to lapses in security awareness or knowledge about security policies among new employees.
