External Repositories

SecurityCenter supports two types of external repositories: Remote Repositories and Offline Repositories. You can configure external repositories to access repositories on other SecurityCenters running version 5.0.0 or later.

Repository data from an external repository is static and used solely for reporting purposes.

For more information, see Repositories and Add a Repository.

Remote Repositories

Remote repositories allow multiple SecurityCenters to share repository data via a SSH session.

SecurityCenter does not support agent repositories as remote repositories.

Option Description

General

Name

The repository name.

Description

Descriptive text for the repository.

Remote SecurityCenter

Host

Host to synchronize with to obtain the repository data. After entering the IP address of the remote SecurityCenter, click the Request Repositories link to type an administrator's username and password for the SecurityCenter to exchange the SSH keys. Once completed, a list of available repositories is populated.

Repository

Remote repository to collect IP address(es) and vulnerability data from. This is a list of the supported repositories available on the remote SecurityCenter.

Schedule

Sets the schedule for the remote server to be queried for updated information.

Access

Organizations

Specifies which organizations have access to the vulnerability data stored in the repository.

If groups are configured for the organization, SecurityCenter 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.

Offline Repositories

Remote repositories allow multiple SecurityCenters to share repository data via manual data synchronization using a .tar.gz archive file.

Option Description

Access

Organizations

Specifies which organizations have access to the vulnerability data stored in the repository.

If groups are configured for the organization, SecurityCenter 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, SecurityCenter generates trend data by taking periodic snapshots of the cumulative database. Trend data is displayed in some SecurityCenter tools (e.g., trending line charts and trending area charts).

SecurityCenter also produces differential trend data, which improves performance when displaying trend data in SecurityCenter tools.

Note: Disable this option to reduce your disk space usage.

Days Trending

Specifies the number of days of cumulative vulnerability data that you want SecurityCenter to display in dashboard and report vulnerability trending displays.

Enable Full Text Search

When enabled, SecurityCenter 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.

To initiate offline repository synchronization, first click on the Export link from the gear icon drop-down menu to download the repository archive from an existing repository.

Depending on browser choice, the browser presents the option to open or save the Nessus or Compressed Tar file. It is recommended that the file be saved at this time.

Tip: Depending on the size of the repository database, this file can be quite large. It is important to save the file to a location with sufficient free disk space.

Tip: When importing the repository archive, the default maximum file import size is 360MB. This is specified by the post_max_size directive in /opt/sc/support/etc/php.ini. If larger file uploads are required, increase the default value.

To load the repository archive to the offline repository, copy it to a location where the offline repository is accessible via the SecurityCenter GUI, open the Repositories page, highlight the offline repository, and click Upload from the gear icon drop-down menu.

On the Upload page, add a name and description for the repository. Next to Repository Data, click Choose File and select the file to add to the previously exported repository.
