Control statement and discussion

NIST control statement

Upon termination of individual employment: a. Disable system access within [Assignment: time period]; b. Terminate or revoke any authenticators and credentials associated with the individual; c. Conduct exit interviews that include a discussion of [Assignment: information security topics]; d. Retrieve all security-related organizational system-related property; and e. Retain access to organizational information and systems formerly controlled by terminated individual.

Discussion

System property includes hardware authentication tokens, system administration technical manuals, keys, identification cards, and building passes. Exit interviews ensure that terminated individuals understand the security constraints imposed by being former employees and that proper accountability is achieved for system-related property. Security topics at exit interviews include reminding individuals of nondisclosure agreements and potential limitations on future employment. Exit interviews may not always be possible for some individuals, including in cases related to the unavailability of supervisors, illnesses, or job abandonment. Exit interviews are important for individuals with security clearances. The timely execution of termination actions is essential for individuals who have been terminated for cause. In certain situations, organizations consider disabling the system accounts of individuals who are being terminated prior to the individuals being notified.

Control statement and discussion

NIST control statement

Use [Assignment: automated mechanisms] to [Selection (one-or-more): notify [Assignment: personnel or roles] of individual termination actions; disable access to system resources].

Discussion

In organizations with many employees, not all personnel who need to know about termination actions receive the appropriate notifications, or if such notifications are received, they may not occur in a timely manner. Automated mechanisms can be used to send automatic alerts or notifications to organizational personnel or roles when individuals are terminated. Such automatic alerts or notifications can be conveyed in a variety of ways, including via telephone, electronic mail, text message, or websites. Automated mechanisms can also be employed to quickly and thoroughly disable access to system resources after an employee is terminated.
