This report provides a detailed analysis of the group membership across many platforms. The supported platforms are Windows, OS X, and LDAP. The report is structured to provide a summary list of systems, and then enumerate the group membership. The report provides details on group membership though SMB enumeration, LDAP search queries, ADSI, and parsing of system configuration files.
The report is available in the SecurityCenter Feed, a comprehensive collection of dashboards, reports, assurance report cards and assets. The report can be easily located in the SecurityCenter Feed under the category Monitoring. The report requirements are:
- SecurityCenter 4.7.1
- Nessus 5.2.5
- LCE 4.2.2
- Tenable LCE Client
The report can be time consuming when ran without additional filters. Therefore, to better use the report, it should run against individual assets or address filters.
To easily modify the report from app feed, choose “Configure Now” and apply the appropriate asset or address filter.
Additionally, if the report is already installed from the feed, you can use the “Find/Update” option above the chapter list.
Next, apply the filter for an address or asset. In the screen shot below, we have made a update to the address filter.
