Alert Impact Explanation

Follow steps below to disable SSLv3 support in nginx on each node in Web Threat Detection:

1. Open /var/opt/silvertail/etc/nginx-scoutproxy.conf and /var/opt/silvertail/etc/nginx-siteproxy.conf
2. Search for the following text in the file:

      # Restrict ssl_protocols
      ssl_protocols SSLv3 TLSv1;

3. Remove the SSLv3 from the ssl_protocols line. There could be multiple occurrences of the ssl_protocols line, make the below change to each occurrence. It should now look like this:

      ssl_protocols TLSv1;

4. Save the files and restart each nginx instance. Not all hosts will be running SiteProxy. All hosts will be running ScoutProxy.

      sudo /etc/init.d/st-ScoutProxy-<hostname> restart
      sudo /etc/init.d/st-SiteProxy-0 restart
