What provides the best security and accountability for a Data Center?

Card keys provide the best security and accountability for a data center because they offer both controlled access and tracking capabilities. Unlike traditional locks, card key systems can be programmed to only allow authorized personnel to enter specific areas, thus enhancing security. Additionally, these systems typically record data such as who accessed the area and when, which is essential for accountability and auditing purposes.

In contrast, entry logging may track entries but lacks physical security measures. Combination locks require users to memorize and input codes, which can be shared or forgotten, reducing security. Dead bolts provide a basic level of physical security but do not offer the same tracking and access control benefits as card key systems. Therefore, the combination of access control and accountability offered by card keys makes them the superior choice for securing sensitive areas like data centers.
