7 Steps To Secure Your Data Center

Modern data centers typically hold vast quantities of data (big data). This will generally include personal data and highly sensitive business data. Probably at least some of this data will be required for critical applications. This means that security has to be a top consideration for all modern data centers. With that in mind, here are 7 steps to secure your data center.

Physical security measures

All security starts with physical security. Here are the four key physical security measures all data centers need to implement.

Location selection: Choose a strategic location, considering factors like natural disaster susceptibility and geopolitical stability. Ensure accessibility for authorized personnel and proximity to emergency services.

Access controls: Implement stringent access controls using biometrics, key cards, or PINs. Assign access levels based on roles to limit entry to authorized individuals.

Surveillance and monitoring: Employ advanced surveillance systems with CCTV cameras and motion sensors. Continuously monitor entry points and critical areas for real-time threat detection.

Disaster recovery and redundancy: Develop comprehensive disaster recovery and redundancy plans. Include backup power sources, redundant networking, and failover capabilities to ensure uninterrupted operations during outages or failures.

Network security

The internet means that data centers can be attacked from anywhere in the world. This means that robust network security is as important as robust physical security. Here are the five key network security measures all data centers need to implement.

Firewalls and intrusion detection systems (IDS): Deploy next-generation firewalls to scrutinize incoming and outgoing network traffic, applying rule-based filtering to identify and block potential threats. Pair these with IDS to detect and respond to suspicious activities.

Network segmentation: Implement network segmentation to partition your data center into isolated zones. This limits lateral movement for cybercriminals within your network, enhancing overall security.

Encryption: Encrypt data in transit using protocols like SSL/TLS and secure data at rest using encryption algorithms. This safeguards data from eavesdropping and theft, particularly during data transfers.

Patch management: Maintain a rigorous patch management strategy to promptly update and patch vulnerabilities in network devices, servers, and applications. Regularly scan for vulnerabilities and apply patches to minimize potential exploits.

Security audits and monitoring: Continuously monitor network traffic for anomalies and employ intrusion prevention systems (IPS) to proactively block malicious activities. Regularly conduct security audits and vulnerability assessments to identify and address weaknesses.

Access controls and authentication

Robust access controls and authentication mechanisms are critical for safeguarding data centers. Here are four key measures all data centers must implement.

Multi-factor authentication (MFA): MFA is slightly slower than using a single authentication method but this is a reasonable trade-off for the increased security.

Role-based access control (RBAC): Assign permissions based on job roles, reducing the risk of privilege misuse.

Data segmentation: Segment data and systems to limit access to sensitive information.

Logging and auditing: Maintain access activity logs for anomaly detection and incident response.

Threat detection and prevention

Securing your data center requires effective threat detection and prevention. Here are the four key threat detection and prevention measures all data centers need to implement.

Threat identification: Identify and understand potential threats, including insider threats and external cyberattacks.

Anomaly detection: Deploy anomaly detection mechanisms and machine learning algorithms to spot unusual behavior patterns.

Real-time monitoring: Implement real-time monitoring tools to continuously assess the data center’s security posture.

Incident response: Develop an incident response plan to identify, classify, and mitigate security incidents with minimal delay.

Compliance and regulations

Ensuring that your data center is compliant with all relevant programs is essential to avoid legal penalties. It will also help to establish your credentials as a reputable provider. Here are the four key measures all data centers need to implement.

Regulatory landscape: Familiarize yourself with industry-specific regulations, such as HIPAA for healthcare or GDPR for data privacy. Remember these can change periodically.

Compliance audits: Regularly conduct compliance audits to assess adherence to legal requirements.

Data classification: Properly classify data based on sensitivity to align with regulatory guidelines.

Documentation: Maintain meticulous documentation of compliance efforts, including policies and procedures. Make sure that all documentation is fully self-contained. In other words, make sure that it can be read by anybody regardless of their level of prior knowledge.

Ongoing security maintenance

Security cannot be a “one-and-done” exercise. It needs to be a process of continuous improvement. Here are the three key measures all data centers need to implement.

Regular updates and patching: Keep all software, including operating systems and security tools, up to date to address vulnerabilities.

Monitoring and logging: Implement real-time monitoring to detect anomalies and maintain detailed logs of activities.

Routine audits: Keep testing your security measures and their associated documentation to identify quickly when and how they need to be updated.

Security training and awareness

Last but not least, remember that your staff can be your biggest security asset or your biggest security weakness. The effectiveness of their training will generally decide which.
