Physical security is a natural and necessary extension of that, and it can be broken down into four main layers:<\/span><\/p>\n<ul>\n<li aria-level=\"1\"><b>The Perimeter<\/b><span style=\"font-weight: 400;\">\u00a0 Property-line physical and psychological deterrents like fencing, lights, and visible security cameras.<\/span><\/li>\n<\/ul>\n<ul>\n<li aria-level=\"1\"><b>Facility Entry<\/b><span style=\"font-weight: 400;\">\u00a0 The primary choke point where individual entries must be monitored with CCTV and electronic access controls.<\/span><\/li>\n<\/ul>\n<ul>\n<li aria-level=\"1\"><b>The Data Hall<\/b><span style=\"font-weight: 400;\">\u00a0 Increasingly, facilities are using multi-factor authentication (MFA) for access to the data hall, requiring \u201csomething you have\u201d (badge, fob) and \u201csomething you are\u201d (biometrics).<\/span><\/li>\n<\/ul>\n<ul>\n<li aria-level=\"1\"><b>The Racks<\/b><span style=\"font-weight: 400;\">\u00a0 Security at the level of the cage and cabinet, especially in colocation facilities. Credentialing and other electronic access control features can ensure a technician only has access to specific servers.<\/span><\/li>\n<\/ul>\n<h3><span style=\"font-weight: 400;\">2. Adopt a Zero Trust Physical Access Model<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">\u201cZero Trust\u201d can sound impersonal, but from a security point of view, it\u2019s a way of treating everyone in a company equally regardless of position. Security at every entry point depends on need for access and the principle of <\/span><b>least privilege<\/b><span style=\"font-weight: 400;\"> rather than your acronym.<\/span><\/p>\n<p><b>Anti-passback <\/b><span style=\"font-weight: 400;\">technology and the <\/span><b>Two-Person Rule<\/b><span style=\"font-weight: 400;\"> are great examples of this. Anti-passback tech requires an exit scan before a badge can be used again. The Two-Person Rule ensures people do not enter restricted areas alone.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">3. Deploy Biometric Access Controls<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">To meet modern data center security standards (like <\/span><a href=\"https:\/\/csrc.nist.gov\/pubs\/sp\/800\/53\/a\/r5\/final\"><span style=\"font-weight: 400;\">NIST SP 800-53A<\/span><\/a><span style=\"font-weight: 400;\">), many data centers are turning to biometric inherence access controls such as fingerprint readers, facial recognition, and iris scanners, either as the primary access credential or as part of an MFA protocol.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">4. Maintain Granular, Real-Time Audit Logs<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Detailed or granular audit logs not only help you investigate breaches, they can be critical for meeting regulatory standards such as SOC 2. Today\u2019s most advanced electronic access controls keep real-time data on:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The identity of the individual<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The specific door or rack accessed<img loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-113963 alignright\" src=\"https:\/\/www.andersonlock.com\/wp-content\/uploads\/2026\/05\/hid_40ktks_00_000000_signo_40_wall_mount_1727695211_1849913-300x300.jpg\" alt=\"\" width=\"300\" height=\"300\" srcset=\"https:\/\/www.andersonlock.com\/wp-content\/uploads\/2026\/05\/hid_40ktks_00_000000_signo_40_wall_mount_1727695211_1849913-300x300.jpg 300w, https:\/\/www.andersonlock.com\/wp-content\/uploads\/2026\/05\/hid_40ktks_00_000000_signo_40_wall_mount_1727695211_1849913-150x150.jpg 150w, https:\/\/www.andersonlock.com\/wp-content\/uploads\/2026\/05\/hid_40ktks_00_000000_signo_40_wall_mount_1727695211_1849913-400x400.jpg 400w, https:\/\/www.andersonlock.com\/wp-content\/uploads\/2026\/05\/hid_40ktks_00_000000_signo_40_wall_mount_1727695211_1849913-100x100.jpg 100w, https:\/\/www.andersonlock.com\/wp-content\/uploads\/2026\/05\/hid_40ktks_00_000000_signo_40_wall_mount_1727695211_1849913.jpg 500w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The precise timestamps of entry and exit<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Any unsuccessful attempts to gain entry<\/span><\/li>\n<\/ul>\n<h3><span style=\"font-weight: 400;\">5. Install Electronic Access to Racks and Cages<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Rather than deal with the administrative and logistical hassle of physical keys, use networked access controls on your cabinets and cages. This allows you to control and monitor who gains access and when as well as offering remote lockdown capabilities.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Networked access controls integrate with your data center infrastructure management (DCIM) software, which lets you manage access across thousands of racks from a central dashboard.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">6. Align with Global Compliance Standards\u00a0<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Compliance certificates and badges signal trustworthiness to your clients.
