Enhancing Data Center Security: Leveraging Key Management Systems

In today’s digital landscape, organizations across all industries face a growing threat of cybercriminal activities. Further exacerbating these challenges comes the threat from within – employee theft and industrial espionage. Consequently, organizations are taking serious measures to bolster their network and data center protection strategies.

One of the most efficient and versatile ways to improve data center security is through the implementation of key management and access control systems. These systems offer a multi-faceted approach towards enhancing security by layering physical protective measures such as video surveillance, mantraps, and access policies and procedures that restrict physical access.

Key management systems are designed to securely hold and automatically monitor key usage. For an authorized user to access a stored key, they simply need to enter their personal identification code on the system keypad. On verification of the user, the system’s door opens and reveals the specific location of the requested key. For an additional layer of security, these systems can also configure with card readers or biometric readers and can network together for centralized control.

Beyond the security provisions, these automated key management systems offer a host of control and usage options that are ideal for data center environments. There are a few scenarios that perfectly illustrate the effectiveness of these systems.

The first scenario involves specialized enrollment, where individuals are given specific access based on their functions. Operations center engineers might have authorized key access round the clock. In contrast, a technician might be restricted to access certain keys for specific durations at particular times. Such access restrictions are also easily programmable for personnel like cleaning staff or security guards. Moreover, the system administrators have the ability to quickly revise or terminate an individual’s access if they leave the job, or their shift changes.

In high-risk environments such as data centers, having an additional layer of protection through access control can be vital. This is where a Remote Box comes in. The key control cabinet is installed in a secure room to protect it against potential vandalism or tampering. The Remote Box is typically installed outside the secure room, and it requires a two-tier authentication process where it validates the inputs from both an authorized employee using the Remote Box and a second employee on the inside.

These key control systems offer an impressive level of versatility, accommodating more complex applications for larger data center environments. For instance, multiple forms of identification may be needed to access different areas of the data center. In this case, a general access badge allows the employee to enter the building, while a second badge helps them access internal areas of the facility. To uphold stringent security, this internal access badge is secured in a key cabinet when not in use by the authorized employee.

Finally, sophisticated key management systems offer customized configurations. This allows for control and restriction of access to various items found in a data center, such as radios, cell phones, handheld computers, and specialized test equipment, among others. Additional modules for the system, such as lockers, can hold and control access to these devices, accompanied by an audit trail that tracks their removal and return.

As we continue to edge closer to a fully virtual world, with more data being stored on the cloud, ensuring robust security for this sensitive information is crucial. The implementation of an effective key management system provides a testament to its integral role in impairing security threats efficiently.
