Why is it important to have logical security controls on endpoints even though the users are trained to spot security threats and the network devices already help prevent them?

Logical security controls primarily protect data and system integrity, while physical security measures are designed to prevent the theft of endpoints.

Defense-in-depth is a multi-layered security strategy that explicitly extends beyond the network perimeter to encompass endpoints, applications, and data itself.

The purpose of implementing security controls is to reduce exposure to threats, not to increase it.

Even with comprehensive user training and robust network security, human error remains a significant vulnerability, and insider threats can bypass network perimeter defenses. Endpoint logical controls provide a critical last line of defense, mitigating risks that originate from within the network or through user interaction.
