3. Fetch Top N installed software (optional, default: 0) - Specify the number of the top most common installed software fetched from Tenable.sc.
   • If supplied, all connections for this adapter will fetch the top N most common installed software fetched from Tenable.sc.
   • If not supplied (or '0') - all connections for this adapter will not fetch any installed software from Tenable.sc.
4. Fetch installed software per device - Choose whether to fetch all installed software from Tenable.sc.
   • If enabled, all connections for this adapter will fetch installed software fetched from Tenable.sc.
     • If you select this option, set Fetch top N installed software as 0.
   • If disabled, all connections for this adapter will not fetch any installed software from Tenable.sc.
5. Fetch vulnerabilities - Select to fetch devices' unmitigated vulnerabilities data from Tenable.sc.
   Note: If you want to also fetch mitigated vulnerabilities appearing in the Mitigated table of Tenable.sc, select Fetch vulnerabilities and Fetch mitigated vulnerabilities.
   When a vulnerability is fetched from the Mitigated table it is marked 'Mitigated - Not Vulnerable'. When a vulnerability is fetched from the cumulative table and was vulnerable before, it is marked 'Previously Mitigated (Currently Vulnerable)'
6. Fetch SCAP scans - Select whether to fetch data from SCAP scans.
   • If enabled, all connections for this adapter will fetch data from SCAP scans.
   • If disabled, all connections for this adapter will not fetch data from SCAP scans.
7. Do not fetch devices with unauthenticated scans only - Choose whether to fetch devices with unauthenticated scans only Tenable.sc.
   • If enabled, all connections for this adapter will fetch devices with authenticated scans only from Tenable.sc.
   • If disabled, all connections for this adapter will fetch devices with authenticated and unauthenticated scans from Tenable.sc.
8. Fetch info level vulnerabilities only for listed plugin IDs (optional) - Specify a comma-separated list of Tenable.sc plugin IDs.
   • If supplied, all connections for this adapter will only collect info level vulnerabilities from Tenable.sc for the plugin IDs provided in this list.
   • If not supplied, all connections for this adapter will not collect any info level vulnerabilities from Tenable.sc.
9. Repository name exclude list (optional) - specify a comma-separated list of Tenable.sc repositories. Repositories are databases within Tenable.sc that contain vulnerability data. For more details, see Tenable.sc - Repositories.
   • If supplied, all connections for this adapter will not fetch vulnerabilities from repositories which are any of the comma-separated list of Tenable.sc repositories that have been defined in this field.
   • If not supplied, all connections for this adapter will fetch any vulnerability regardless of their Tenable.sc repository.
10. Repository name exclude list - use 'contains' logic instead of exact match - Select whether to consider the values supplied in Repository name exclude list field as the exact repository names.
