CIS Microsoft Windows 10 Enterprise Release 1909 Benchmark

Remediation:

To establish the recommended configuration via GP, set the following UI path to Enabled: 90% or less :

Computer Configuration\Policies\Administrative Templates\MSS (Legacy)\MSS: (WarningLevel) Percentage threshold for the security event log at which the system will generate a warning

Note: This Group Policy path does not exist by default. An additional Group Policy template ( MSS-legacy.admx/adml ) isrequired - it is available from this TechNet blog post: The MSS settings – Microsoft Security Guidance blog

Impact:

An audit event will be generated when the Security log reaches the 90% percent full threshold (or whatever lower value may be set) unless the log is configured to overwrite events as needed.

Default Value:

0%. (No warning event is generated.)
