Personnel Security Access

Purpose: This MARADMIN reinforces current policy and guidance for 
personnel who require access to classified information.  
2. Background: To receive access to classified information, 
personnel must demonstrate a clear need-to-know based on their 
current billet assignment.  Commanders make need-to-know 
determinations for every person requiring access within their 
command.
3. Execution:
3.a. Per the references, only personnel who have demonstrated a 
valid need-to-know in direct support of their current billet 
assignment shall be granted access to collaterally classified 
material or indoctrinated into Sensitive Compartmented Information 
(SCI). After review and approval from their Command Security Manager 
and/or Special Security Officer, an entry will be made in the Defense 
Information Systems for Security (DISS) upon indoctrination.  
3.b. Per the references, personnel without a current demonstrated 
need-to-know shall be immediately debriefed from their access to 
classified information. Upon debrief, the Command Security Manager 
and/or the Special Security Officer will make an entry for removal 
of accesses in DISS. No member shall have access to classified 
information while on administrative leave, after retirement or EAS, 
or after resignation from their position, to include voluntary 
separation under the Deferred Retirement/Resignation Program or 
involuntarily separated.  Active-duty personnel on terminal leave 
may retain access based on a need-to-know for turnover purposes 
only, pending approval of the Commanding Officer.  All personnel 
must be debriefed and disowned on their last day in the Service, 
with an entry made in DISS.  Personnel who do not sign their 
security debriefings shall be administratively debriefed by the 
Command Security Manager and/or the Special Security Officer.
3.c. Command Security Managers and/or Special Security Officers 
shall contact the command S/G-6 for removal of information 
technology accounts for personnel who no longer have a 
need-to-know. Units will follow local procedures for deletion of SCI 
Net accounts.   
4. Reporting Requirements:  
4.a. Command Security Managers and/or Special Security Officers 
shall report any personnel debriefed for cause to Headquarters 
Marine Corps Personnel Security Program Manager, who will evaluate 
the circumstances of the debrief and determine whether the case 
should be referred to the USMC Counter Insider Threat Program.
