Which is NOT a benefit of implementing physical security measures in IT?

Improvement of network performance is not a benefit of implementing physical security measures in IT. While physical security measures, such as access control systems, surveillance cameras, and environmental controls, play a crucial role in safeguarding IT infrastructure from unauthorized access, theft, and physical damage, they do not directly contribute to enhancing the performance of the network itself.

Network performance primarily depends on factors such as bandwidth, latency, system architecture, and network configuration. While a secure environment can indirectly support performance by ensuring that systems are not compromised or affected by security incidents, the implementation of physical security is primarily focused on protecting the physical assets and ensuring the safety of personnel. Other options like protection against unauthorized access, deterrence of theft or damage, and enhanced employee safety are all direct benefits of establishing robust physical security measures in an IT context.
