You can schedule the scans to repeat them. Personally I wasn’t happy with the built in scheduler and automated one myself using python talking to the gvm-tools API. (https://github.com/Thijssss/openvas_scheduler which might help you automate things yourself, gvm-tools also has example scripts: https://bitbucket.org/greenbone/gvm-tools)
I am not going for differences really; any finding with a CVSS score of > 4 will trigger an alert which sends an email to our ticketing system. Once a month I start my scheduler which will start any job that hasn’t run for 3 weeks or so. (I could leave it running in a screen forever but I still supervise and time it all, when it is not running I got time to update scan systems) If you go to tasks and click on the Reports > Total number you can see an overview of all the reports and quickly see if things improved or not. There is a compare button (underneath Actions, next to ‘delete’ so be careful), click on two and you’ll get a comparison overview. Still, why care about past results; it’s the latest scan result that counts in my book. Thijs Stuurman Security Operations Center | KPN Internedservices B.V.

Our next move is basically to identify differences between consecutive scans on hosts (was a vulnerability patched? was a new vulnerability introduced on the system?) Based on my understanding, the system does not support this natively but I can be wrong. How do others solve this issue? Do you build automation around it ? Best regards Joris
