| Inactive user accounts pose a risk to systems and applications. Owners of inactive accounts will not notice if unauthorized access to their user account has been obtained. Attackers able to exploit an inactive account can potentially obtain and maintain undetected access to the operating system. Operating systems need to track periods of user inactivity and disable accounts after an organization-defined period of inactivity. Such a process greatly reduces the risk that accounts will be misused, hijacked, or data compromised. Applicable, but permanent not-a-finding - root is the only local user account, and should never be considered inactive. All other accounts (excepting vpxuser, which is password-updated every 30 days or less) are required to be Active Directory accounts. |
