The NSA seal is protected by Public Law 86-36, which states that it is not permitted for “…any person to use the initials ‘NSA,’ the words ‘National Security Agency’ and the NSA seal without first acquiring written permission from the Director of NSA.”     At any time that NSA is made aware that the NSA Seal is being used without our permission, we will take appropriate actions. 

That’s rich!
