Appendix 5: Offline SecurityCenter Plugin Updates
Nessus
1. If not already in place, install a Nessus scanner on the same host as SecurityCenter. It does not need to be
started or used though.
2. Run this command and save the challenge string:
# /opt/nessus/bin/nessus-fetch --challenge
3. Go to https://plugins-customers.nessus.org/offline.php.
4. Take the challenge string from Step 2 and your Activation Code, and place those values in the appropriate fields
on the web page. Click the “Submit” button.
5. On the next page, copy the link that starts with http://plugins.nessus.org/get.php... and save it as a favorite. Within
the saved link change “all-2.0.tar.gz” to “sc-plugins-diff.tar.gz”. This link may be needed for future use. Do not
click the link for nessus-fetch.rc as it is not needed.
6. Go to the favorite you created, this will prompt you to download a file. Download the file; it will be called sc-
plugins-diff.tar.gz.
7. Take the sc-plugins-diff.tar.gz and save this on the PC where you access your SecurityCenter GUI.
8. Log into the SecurityCenter GUI as admin.
9. Go to Plugins -> Plugins.
10. Click “Upload Plugins” and browse to the saved sc-plugins-diff.tar.gz file, and then click “Submit”.
11. The plugin update will take a few to several minutes, depending how many Nessus scanners you have attached.
A message with the current date for the updated active plugins will appear when the update is finished.

1. Go to http://downloads.nessus.org/sc-passive.tar.gz and download the archive to a location browseable from
SecurityCenter.
2. Log into SecurityCenter and go to “Plugins” and then “Upload”. Choose the sc-passive.tar.gz file. For type, select
“Passive” and then complete the PVS plugin upload.
