What is the minimum number of co-located TAs required at a duty station?

The minimum number of co-located Trusted Agents (TAs) required at a duty station is two. This requirement is in place to ensure operational efficiency and continuity of service, especially in critical functions related to the Public Key Infrastructure (PKI).

Having two TAs at a location allows for better coverage and support, as they can serve as backups for each other. In the event that one TA is unavailable due to illness, leave, or other commitments, the other TA can continue assisting personnel with PKI-related tasks, such as issuing certificates, handling inquiries, or supporting security operations. This redundancy helps maintain service availability and ensures that crucial PKI processes are not disrupted.

Additionally, having multiple TAs at a location promotes collaboration and knowledge sharing, which can enhance the overall effectiveness of PKI operations. It allows for the sharing of best practices and experiences, minimizing the risk of critical knowledge being siloed with just one individual. Overall, this structure reflects the Army's commitment to maintaining robust security protocols and support systems within its PKI framework.
