Is it necessary for a subscriber to keep their SIPRNet token after retirement?

A subscriber must return their SIPRNet token upon retirement because these tokens are considered government property, essential for maintaining the security and integrity of the network. The management of these tokens is strictly regulated within the U.S. Army's Public Key Infrastructure (PKI) system, as they are linked to the individual’s access to classified information and systems.

Keeping a SIPRNet token after retirement could pose security risks since the individual would no longer be authorized to access SIPRNet resources. Returning the token ensures that access to sensitive information is tightly controlled and that only authorized personnel have the means to engage with the SIPRNet environment. This practice also supports the Army's commitment to safeguarding national security and adhering to established protocols regarding the turnover of equipment upon a personnel change.
