| Since the accounts in the IDPS are privileged or system level accounts, account management is vital to the security of the IDPS. Account management by a designated authority ensures access to the IDPS is being controlled in a secured manner by granting access to only authorized personnel with the appropriate and necessary privileges. Auditing account modification along with an automatic notification to appropriate individuals will provide the necessary reconciliation that account management procedures are being followed. If modifications to management accounts are not audited, reconciliation of account management procedures cannot be tracked.
This requirement is applicable for accounts created or maintained using the IDPS application itself rather than the underlying OS or an authentication server. Accounts created and maintained on AAA devices (e.g., RADIUS, LDAP, or Active Directory) are secured using the applicable security guide or STIG.
To support the auditing requirement, the IDPS account and audit management functions must be configured to transmit events to the site's central audit server (e.g., SYSLOG server), as required by CCI-000136. |
