Discussion

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.
