The Significance of Physical Security within the Data Center

While most discussions of IT security focus on logical controls, protection of the physical data center infrastructure is becoming increasingly important. The European Union (EU) General Data Protection Regulation (GDPR), which goes into effect next May, illustrates this point.
The GDPR is a strict new law governing the security and privacy of the personal data of anyone living in the EU. Although it is designed to standardize data privacy legislation across Europe, it has significant implications for companies around the world. It applies to any organization — regardless of its size or location — that collects and stores the data of EU residents.

The regulation mandates that all organizations know exactly where every instance of someone’s personal information is located and “implement appropriate technical and organizational measures” to ensure the protection of that data. Among the minimal organizational measures is ensuring the physical security of the premises where data is stored.

The GDPR isn’t the only regulation mandating physical data center security. For example, the Payment Card Industry Data Security Standard (PCI DSS) requires that organizations restrict and monitor access to any facility that houses systems used for storing, processing, or transmitting cardholder data. HIPAA prescribes “physical measures, policies, and procedures to protect a covered entity’s electronic information systems and related buildings and equipment, from natural and environmental hazards and unauthorized intrusion.”

Most data centers have implemented physical security measures such as electromechanical door locks, smartcard or biometric access controls, and video surveillance systems. As with all IT security issues, however, humans are the weakest link. Data thieves can gain entry by “tailgating” behind employees or posing as building maintenance personnel. Malicious insiders who have the freedom to roam through all parts of the facility can gain almost unfettered access to IT systems.

Implementing Physical Security in the Data Center

  • Controlled access: Implementing strict access control measures such as biometric authentication, ID card systems, and video surveillance to ensure only authorized personnel can enter the data center.
  • Perimeter protection:Utilizing fencing, gates, and security barriers to establish a secure boundary around the data center premises.
  • Surveillance systems: Deploying advanced CCTV cameras and monitoring systems to continuously monitor the data center facility and detect any unauthorized activities or breaches.
  • Security personnel: Employing trained security personnel who can provide on-site monitoring, respond to incidents, and enforce security protocols within the data center.
  • Alarms and alerts: Installing intrusion detection systems and alarms that immediately notify security personnel in case of any security breaches or unauthorized access attempts.
  • Environmental controls: Implementing measures such as fire detection and suppression systems, temperature and humidity monitoring, and water leak detection systems to protect the data center from physical threats.
  • Equipment protection: Utilizing secure racks, cabinets, and cages to protect critical equipment from theft or damage.
  • Visitor management: Implementing visitor registration processes, escort policies, and visitor access restrictions to ensure that only authorized individuals can access specific areas within the data center.
  • Redundancy and backup systems: Implementing backup power systems, redundant network connections, and disaster recovery plans to ensure uninterrupted data center operations even during emergencies or power outages.
  • Regular audits and testing: Conducting routine security audits, vulnerability assessments, and penetration testing to identify and address any potential security weaknesses or vulnerabilities in the data center’s physical infrastructure.

When it comes to security and regulatory compliance, organizations are rightfully concerned about firewalls, intrusion prevention systems, and other logical controls. However, the most sophisticated security tools are useless if cybercriminals can enter the data center facility and access or tamper with the equipment. As organizations prepare for GDPR compliance, they should take a hard look at their physical security strategies and infrastructure, and implement policies and procedures for keeping intruders away from sensitive data.
