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.

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 (F-25129r944314_fix)
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.
