Universal Repositories

Universal repositories can store data from Nessus and Nessus Agent scans, as well as IPv4 and IPv6 data from NNM, and LCE scans.

Tenable.sc assigns UUIDs to assets to uniquely identify vulnerability data in universal repositories, since not all operational technology assets have IP addresses or Tenable UUIDs.

For more information, see Add a Repository.

Universal Repository Options

Option	Description
General
Name	The repository name.
Description	(Optional) A description for the repository.
Data
IP Ranges	Specifies the IP address range of vulnerability data you want to store in the repository. Type the range as a comma-delimited list of IP addresses, IP address ranges, and/or CIDR blocks. Note: Agent scans into universal repositories are not restricted by IP range.
Access
Organizations	Specifies which organizations have access to the vulnerability data stored in the repository. If groups are configured for the organization, Tenable.sc prompts you to grant or deny access to all of the groups in the organization. For more granular control, grant access within the settings for that group.
Advanced Settings
Generate Trend Data	When enabled, Tenable.sc generates trend data by taking periodic snapshots of the cumulative database. Trend data is displayed in some Tenable.sc tools (e.g., trending line charts and trending area charts). Tenable.sc also produces differential data (snapshot comparison data), which improves performance when displaying trend data in Tenable.sc tools. Tip: Disable this option to reduce your disk space usage.
Days Trending	Specifies the number of days of cumulative vulnerability data that you want Tenable.sc to display in dashboard and report vulnerability trending displays.
Enable Full Text Search	When enabled, Tenable.sc includes vulnerability text in periodic snapshots of .nessus data for vulnerability trending purposes. For more information about the Vulnerability Text filter component, see Vulnerability Analysis Filter Components.
Vulnerability Data Lifetime (Data Expiration Settings)
Active	The number of days you want Tenable.sc to retain active scan vulnerability data stored in universal repositories. The default value of this option is 365 days.
Passive	The number of days you want Tenable.sc to retain passive scan vulnerability data stored in universal repositories. The default value of this option is 7 days.
Event	The number of days you want Tenable.sc to retain event data stored in universal repositories. The default value of this option is 365 days.
Compliance	The number of days you want Tenable.sc to retain audit compliance data stored in universal repositories. The default value of this option is 365 days.
Mitigated	The number of days you want Tenable.sc to retain mitigated vulnerability data stored in universal repositories. The default value of this option is 365 days.
