What category of NIST Handbook refers to special log-in accounts that are preconfigured?

The category of NIST Handbook that refers to special log-in accounts that are preconfigured is specifically related to Maintenance. This category emphasizes the importance of managing and maintaining systems, which includes the process of setting up and maintaining user accounts, especially those that are not regularly used but are necessary for system administration, maintenance, or emergency access.

By having preconfigured log-in accounts, organizations can ensure that specific maintenance tasks can be performed without delay in situations that require immediate attention. This practice also supports the principle of least privilege by allowing limited access necessary for maintenance while controlling and monitoring those special accounts to prevent unauthorized use.

The focus on maintenance highlights the need for diligent processes around managing these types of accounts, ensuring that they are secure, used appropriately, and monitored effectively to mitigate risks.
