This is how I would do it, and the ways I have heard others have done it:
* The web interface you show to your user needs to know almost
nothing about w3af
* When the user clicks on "start scan" a new w3af scan script [0] is
created. Your SaaS will most likely have 3 or 4 different scan script
templates, for different use-cases your customers might have. The
template is filled with the target URL, credentials, etc. all provided
by the user, and then sent to a scan queue.
* The scans just sit in the queue until one of the scan workers gets to them
* Scan workers are EC2 instances that read scan scripts from the
queue and execute them. If you want to get fancy, you can measure the
scan queue size and do +1 or -1 on the number of scan workers
depending on load
* The scan script should be configured to use output.xml_file output.
This plugin writes data to disk every ~30 seconds or so.
* The scan worker server will run w3af_console -s script AND another
process that monitors the XML file. This process will extract
vulnerabilities from the file and save them to a vulnerabilities
queue. The process that monitors the XML file should only report new
vulnerabilities, no duplicated vulns should be sent to the
vulnerabilities queue.
* Another process will read vulnerabilities from the queue and store
them to the DB. The front-end web application reads vulnerabilities
from the DB. Stuff like marking them as a false positive are handled
in the DB, w3af knows nothing about that.
* Just like there is a queue for vulnerabilities, you could add a
queue for scan progress. The XML file also contains that information.
Makes sense?
