Data center security relies on a layered defense strategy designed to protect critical infrastructure from unauthorized access or disruption. The outermost layer typically includes perimeter fencing, vehicle barriers, and controlled entry points that prevent unauthorized vehicles or individuals from entering the site.

Within the facility, security systems include electronic access control, biometric authentication, and mantrap entry systems that require multiple forms of identity verification. Video surveillance systems monitor both interior and exterior areas of the facility, often supported by a security operations center that monitors activity continuously.

These systems work together to ensure that only authorized personnel can access sensitive infrastructure areas, protecting both physical equipment and the digital services that rely on it.
