Description
Without the use of automated mechanisms to scan for security flaws on a continuous and/or periodic basis, the operating system or other system components may remain vulnerable to the exploits presented by undetected software flaws. The operating system may have an integrated solution incorporating continuous scanning using HBSS and periodic scanning using other tools.

Check Text ( C-5993r355102_chk )
Verify DoD approved HBSS software is installed, configured, and properly operating. Ask the operator to document the HBSS software installation and configuration. If the operator is not able to provide a documented configuration for an installed HBSS or if the HBSS software is not properly configured, maintained, or used, this is a finding.

Fix Text (F-5993r355103_fix)
Install a DoD approved HBSS software and ensure it is operating continuously.
