We scanned an application on AWS after 24hrs it got aborted though we enabled progressive scan. can anyone tell me the cause for this and how to re scan.
24hrs is the maximum time that a scan will run for. You mentioned that you have progressive scanning enabled so what will happen is the next scheduled scan for the application will carry on for where the first finished.
There is also a max number of links. You will need to tune the scan such as turning on the smart scan option and/or skiping binary files etc..
For more information about progressive scanning, see the following articles.
