Agent Repositories

Agent repositories can store data from Nessus Agents (identified by agent ID) or Tenable.ot (identified by Tenable.ot UUID).

An agent ID uniquely identifies agent-detected assets that may share a common IP address.

Tenable.ot assigns UUIDs to assets in order to uniquely identify them, since not all operational technology assets have IP addresses. Then, Tenable.sc uses the UUIDs to uniquely identify Tenable.ot data in Tenable.sc. For more information about viewing Tenable.ot data in Tenable.sc, see Tenable.ot Instances.

For more information, see Add a Repository.

Option Description
General
Name

The repository name.

Description

(Optional) A description for the repository.

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.
