Microsoft Windows Server 2019 STIG Version Comparison
Microsoft Windows Server 2019 Security Technical Implementation Guide
There are 2 differences between versions v2 r1 (Nov. 13, 2020) (the "left" version) and v2 r2 (May 4, 2021) (the "right" version).
Check WN19-00-000290 was changed between these two versions. Green, underlined text was added, red, struck-out text was removed.
Windows Server 2019 must employ automated mechanisms to determine the state of system components with regard to flaw remediation using the following frequency: continuously, where Host Based Security System (HBSS) is used; 30 days, for any additional internal network scans not covered by HBSS; and annually, for external scans by Computer Network Defense Service Provider (CNDSP).
Verify DoD approved DoD-approved HBSS ESS software is installed, installed configured, and properly operating. Ask the operator to site ISSM for document documentation of the HBSS ESS software installation and configuration. If the operator ISSM is not able to provide a documented configuration for an installed HBSS ESS or if the HBSS ESS software is not properly configured, maintained, maintained or used, this is a finding. finding. Note: Example of documentation can be a copy of the site's CCB approved Software Baseline with version of software noted or a memo from the ISSM stating current ESS software and version.
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.
Install a DoD approved DoD-approved HBSS ESS software and ensure it is operating continuously.
