· RHEL 8 temporary user accounts must be provisioned with an expiration time of 72 hours or less.
Additional details:
● Both analysis and remediation checks are included.
● Some of the checks allow you to use the parameterized setting to enable customization for compliance evaluation. Note that parameterization and remediation actions require the creation of a custom site.
● Improved a few checks by adding the pending restart feature to them. The pending restart feature works in the following ways:
● The action results will show “Pending Restart” instead of “Fixed” for those checks which require OS reboot.
● The check will show relevant for those endpoints until they are rebooted.
● Post reboot of the endpoint the action results will show as “Fixed” and the check will be compliant.
Actions to take:
● To subscribe to the above site, you can use the License Overview Dashboard to enable and gather the site. Note that you must be entitled to the BigFix Compliance product and you must be using BigFix version 10.0 and later.
● If you use custom sites, update your custom sites accordingly to use the latest content. You can synchronize your content by using the Synchronize Custom Checks wizard. For more information, see Using the Synchronize Custom Checks wizard
