What is a key practice for controlling physical access to a datacenter?

Severe limitations on physical access to a datacenter are crucial for ensuring the security and integrity of critical systems and sensitive information housed within. This practice involves implementing strict access controls, such as requiring key cards, biometric scans, or other identification measures for entry.

The rationale behind this approach is to minimize the risk of unauthorized individuals gaining access to physical resources that could compromise the datacenter's security, such as servers, networking equipment, or confidential data. By controlling who can enter the facility, organizations significantly reduce the threat of insider attacks, theft, vandalism, and potential disruptions to operations.

In addition, limiting physical access helps to create a controlled environment where surveillance, monitoring, and security protocols can be effectively enforced, enhancing overall security posture. This practice is a fundamental aspect of a defense-in-depth strategy that protects both the physical and digital assets of an organization.
