Discussion

System package management tools can obtain a list of updates and patches from a package repository and make this information available to the SA for review and action. Using a package repository outside of the organization's control presents a risk of malicious packages being introduced.

Check Content

Check for the existence of a cron job called opensuse.org-online_update
# find /etc/cron* -name opensuse*
If a symlink or executable script is found, this is a finding.

Fix Text

Disable the Automatic Online Update option using YaST.
# /sbin/yast2 online_update_configuration
Uncheck the “Automatic Online Update” selection.
Select “Finish” to exit  
If /etc/<cron directory>/opensuse.org-online_update still exists, remove it manually
rm /etc/<cron directory>/opensuse.org-online_update
