IP Version
Determines if the repository will store IPv4 or IPv6 results. SecurityCenter repositories
cannot store a mix of IPv4 and IPv6 addresses.
Trending
If trending is not selected, any query that uses comparisons between
repository snapshots (e.g., trending line charts) will not be available.
This option allows for a periodic snapshot of the .nessus data for vulnerability trending
purposes. This option is particularly useful in cases where trending is important. In
situations where repository datasets do not change frequently – negating the need for
trending – disable this option to minimize disk space usage.
Generate Nessus File
Use this option to schedule how frequently the Nessus file snapshot will be taken.
Available options include: Never, Daily, Weekly, Monthly (Day), and Monthly (Date).
The .nessus files generated by this process can be imported into Nessus scanners or
any third-party tool that accepts the .nessus format as required.
Download Format
Allows for selecting between the Nessus v1 and v2 formats for the generated Nessus
file. When IPv6 data is used, the v2 format must be selected.
IP Ranges
Allowed ranges for importing vulnerability data. Addresses may be a single IP address,
IP range, CIDR block or any comma-delimited combination (20 K character limit).
Organizations
Organizations that have access to the vulnerability data within the repository. Within
the “Organizations” section, click the green key icon for access control options. Access
is available for the “Organization Head” user or for “All Users” within the Organization
(affects existing users only). For existing repository edits, an additional option labeled
“Existing Users” is available. This option leaves the current user access intact. Click
“Submit” to apply the changes.
To initiate offline repository synchronization, first download the repository archive from an existing repository by clicking
on the “Download” link. You may download the archive as a Nessus or Compressed Tar (.tar.gz) formatted file.
Depending on browser choice, the option to open or save the Nessus or Compressed Tar file is presented. It is
recommended that the file be saved at this time.
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 plenty of free disk space.
