“Re-challenge for CAC PIN every” must be set.


Finding ID Version Rule ID IA Controls Severity
V-24987 WIR-GMMS-004 SV-30727r2_rule ECSC-1 Low
A user’s CAC PIN or software certificate PIN is cached in memory on the device for a short period of time so a user does not have to re-enter his/her PIN every time the user’s digital certificates are required for an S/MIME operation. The cached memory is cleared after a set period of time to limit exposure of the digital certificates to unauthorized use. Otherwise, a hacker may be able to gain access to the device while the PIN is still cached in memory and access the Good application and gain access to sensitive DoD information.
