Establishing a Standard: Physical Access Control Safeguards the Data Center Boom

Beyond cybersecurity, intelligent key cabinets and asset lockers are becoming critical infrastructure for managing high-stakes physical security at scale.

Cities and towns across the country are rapidly transforming as data centers continue to expand to support an increasingly digital world. The growth of cloud computing, artificial intelligence, and high-speed connectivity has accelerated demand for facilities capable of housing thousands of servers and processors.

But in the race to build this infrastructure, one critical consideration is often overlooked: the operational systems that control access to the facility itself.

For data center operators, security is not limited to cybersecurity. Physical access to keys, equipment and restricted areas must be carefully managed to protect sensitive infrastructure and ensure safe, efficient operations. As facilities grow, complexity, and geographic distribution, establishing standardized access management practices becomes essential.

Optimal security is rooted in the comprehensive management and insight into who has access to which area and which assets within a facility. Although digital credentials on cell phones and electronic badges are becoming commonplace, physical keys are still an integral part of data center operations, both as a primary access asset and as a redundant measure in the event of a system compromise.

As such, key management is vital to ensure efficient operations within facilities and needs to be at the forefront of establishing workflows, particularly in new buildings. Failing to do so leaves data centers vulnerable to unauthorized access, which can be especially risky in the construction phase when a variety of vendors have access to various parts of the facility. In fact, that building period should serve as a default training exercise for operators in the effective management of who has access to which area.

An essential tool in ensuring effective key management within data centers is leveraging intelligent key cabinets throughout a facility. These solutions secure a variety of keys and badges in a central location, and administrators can remotely designate who has access to which key and see when each key was removed and returned.

Access to these cabinets can be granted through several credentials, including an employee’s main access badge, when the cabinet is integrated into the central security software platform. If a key or badge that is stored in the cabinet is not returned by a certain time, a manager is notified, which helps reduce the time it takes to find a misplaced asset. This helps instill accountability within a data center, as employees or vendors know they’re being held responsible for how they use that key.

All usage is recorded and compiled in an audit report, which helps maintain operational transparency and can assist in any regulatory compliance that operators may have to adhere to.

One of the biggest advantages of integrating modern intelligent key cabinets within data centers is the ability to remotely check all key usage. Some data center facilities are massive buildings or campuses with a variety of areas that require various levels of access management. By leveraging multiple key cabinets in strategic areas, operators can not only streamline access campus-wide, but also monitor that usage from a central location, instead of having to be on-site to oversee it directly.

That allows operators to potentially reduce on-site staffing while maintaining an elevated level of security and visibility. This is especially applicable to modular facilities that are being constructed quickly for edge and micro data center needs. If intelligent key cabinets are already integrated into an operator’s access control platform, simply adding another one for a smaller facility is a quick and easy way to ensure that facility has the right security infrastructure in place, regardless of how remote it is or how few employees or vendors are using it.

The same concept of managing physical access through intelligent key cabinets can be applied to shared asset management as well. Modern asset management lockers safely store critical assets like tablets, laptops and radios that many data center operators use every day. Similar to keys and key cabinets, their usage can be tracked remotely, and an administrator can assign access to certain assets to make sure the right employees are using the right technology.

If there is a fault with any of the shared assets, the employee notes that in the locker’s interface, which then removes that asset from circulation until it has been corrected.

Additionally, intelligent lockers charge the assets and prioritize the most charged device, so that when an employee goes to remove one, they’re getting a device with the most battery life possible. This reduces the likelihood of an employee removing a dead device, which can hinder downtime spent finding one that works.

While the need for data management is increasing and many operators are subsequently rushing to get these facilities built, there must be a consideration of how to do it safely and effectively. There is too much risk of doing so haphazardly, and not supporting a suitable system of access management to these critical facilities is setting operators up for failure.

By integrating foundational technology like intelligent key cabinets and asset management lockers, data center operators are not only setting up a comprehensive network of effective management at the onset but also solidifying a base for scalability, as these solutions can be integrated seamlessly into additional facilities and sites.

Such will be the signature of effective data center operations, which can be traced back to a simple concept: effective management of keys and assets.
