Its been a long time since I retired from the fed-gov. I had a TS back in the day and my recollection is as follows.
Every TS document has a document custodian. If you run the SKIF you are the custodian of all the TS documents contained therein because you had to sign for them when they when they were given to you.
If someone with clearance needs a document you sign it out to them but you maintain the record of who you signed it out to because its your butt if it goes missing.
No one, even with clearance, can simply rummage through a SKIF and just take what they want because the custodian is responsible for them. If they go missing he is on the hook for administrate or criminal violations. They do regular audits.
So the document custodian knows to who, when and why the documents were released and has a record. Now I realize that there may be multiple copies of the document at different locations but they all have tracking to ensure they just don’t go missing.
Someone correct me if I am wrong.
I had a TS but on a ship. The whole ship was basically a secured area while at sea. In port the communcations officer kept TS docs etc..
You mean SCIF.
