How to Secure Server Racks?

A server is a specialized computer designed to work with resource-intensive utilities. It is a mega-brain that supplies functioning systems with commands. The server is used in the local network of the company; with its help employees store and exchange files, get access to shared printers and scanners, work with 1C-Enterprise and databases. Servers also provide hosting – website operation (for example, they answer requests from users, store content, process the execution of scripts.

Usually, the server is located in a data center or server room; it is connected to electricity and the Internet all the time. If the server goes down suddenly, the company will suffer financial losses.

In the article, you’ll learn how to implement server rack security measures to protect and secure your data center infrastructure

Reasons to Secure Server Cabinet

The below-mentioned cases are the main reason to keep the security of the servers. There are other situations that may influence its uninterruptible functioning, such as:

• accidental damage

Server racks are characterized by an open-frame design, which means that the installed hardware is not protected from unauthorized access. Typically, such furniture pieces are stored in data centers, access to which is limited. However, no one is protected from accidents and unintentional damages.

• intentional damage

In some cases, offended employees or malefactors who got into the server room can disable the USB port or infect equipment with ransomware, which will lead to equipment malfunction or breakage.

• personal harm

Data centers have limited access for a reason. Cable routing occupies a lot of places, and it is no wonder that someone can trip over them. Thus, only professional employees, which are authorized to conduct maintenance, have access to them. However, even they are not protected from facing such a problem.

• climate control

As for climate control, optimal temperature conditions must be maintained in data rooms. However, programs or mechanisms may fail to provide the required climate control in the premises, which will inevitably cause server functioning. Also, if someone leaves the door open, this leads to changes in climatic conditions. As a result, a climate control system starts working differently to optimize humidity and temperature.

• data theft

Someone can simply pluck out a hard drive from the server rack and take it away.

To avoid these cases, one should arrange proper data center protection.

Server Rack Security Measures

Keeping your data center secure starts with safeguarding its heart: the server racks. Here are some critical security measures to ensure the highest level of protection and integrity for your equipment and data:

Access Control:

• Key Card Locks: Limited-distribution key cards grant access to authorized personnel while remaining unknown to individuals lacking cards. This prevents unauthorized access even if an employee leaves the company.
• Biometric Locks: Fingerprint or retina scanners offer an affordable alternative to key cards, providing personalized access without the risk of shared keys.
• Dual-Factor Authentication: Combining key cards with biometric verification adds an extra layer of security, ensuring only authorized individuals gain access.
• Smart Locks: Integrated with access control systems, smart locks offer remote management and granular control over access privileges for different users.

Physical Security:

• Lock-and-Key (Legacy): While simple and outdated, basic locks can still offer a deterring factor. Consider them as a supplemental measure rather than a primary solution.
• Logging Server Room Access: Detailed logs track who accessed the server room and when, ensuring accountability and aiding in potential investigations.
• Auto-Closing Doors: Eliminate the risk of accidentally open doors with hydraulic or spring-loaded doors. Adding alarm systems further strengthens security by notifying IT personnel of prolonged door openings.
• Locked Rack Cages: Enclosing server racks in secure cages offers an additional layer of physical protection against tampering and unauthorized access. Consider cable locks and tamper seals for even greater security.

Advanced Security:

• Environmental Monitoring: Real-time monitoring of temperature, humidity, and power fluctuations helps prevent hardware damage and data loss.
• CCTV Surveillance: Strategically placed cameras deter unauthorized access and allow for visual confirmation of activity within the server room.
• Alarm Systems: Motion sensors, door/window alarms, and other intrusion detection systems provide immediate alerts for potential security breaches.
• Redundancy and Disaster Recovery: Ensure critical data is backed up and replicated to ensure business continuity in case of hardware failure or cyberattacks.

Remember:

• Choose your security measures based on your specific requirements and budget.
• Security is a layered approach; combine different measures for optimal protection.
• Regularly review and update your security protocols to adapt to evolving threats.

By implementing these server rack security measures, you can create a robust and secure environment for your data center, safeguarding your most valuable assets.
