Check Text ( C-7461r2_chk )
Interview the ISSO and the IDPS administrator. Have the IDPS administrator display update notifications that have been received, the build number or patch level, then search the vendor’s vulnerability database for current release and patch level. If software and signatures are not updated when updates are provided by the vendor, this is a finding.

Fix Text (F-7655r3_fix)
Have the IDPS administrator subscribe to the X-press notification or similar service offered by the vendor. Ensure the IDPS software is updated when software is available either by DISA or the vendor for security related distributions.
