Configuring the operating system to implement organization-wide security implementation guides and security checklists ensures compliance with federal standards and establishes a common security baseline across DoD that reflects the most restrictive security posture consistent with operational requirements.
Check Content
From the ACF Command screen enter: SET LID LIST IF(REFRESH) If procedures exist to utilize the logonid with the REFRESH attribute to refresh ACF2 global options, this is not a finding. Example of a suggested procedure follows: When the ISSO determines it necessary to refresh the ACF2 global options, the ISSO will do the following: -Activate the REFRESH ID with the following setting(s): NOSUSPEND NOPSWD EXP PASSWORD(new password) -Instruct Operations to perform the REFRESH. -Deactivate the REFRESH ID with the following setting: SUSPEND If no procedures exist in accordance with the STIG requirements to utilize the logonid with the REFRESH attribute to refresh ACF2 global options, this is a finding.
Fix Text
Review security procedures for defining LOGONIDs and develop documentation of requirements for the LOGONID associated with the REFRESH attribute. Example of a suggested procedure follows: When the ISSO determines it necessary to refresh the ACF2 global options, the ISSO will do the following: -Activate the required REFRESH ID with the following setting(s): NOSUSPEND NOPSWD EXP PASSWORD(new password) -Instruct Operations to perform the REFRESH using the newly activated REFRESH ID. -After refresh is completed. -Deactivate the REFRESH ID with the following setting: SUSPEND This procedure should be documented in the Site Security Plan.
