Delta Analysis reports

The Delta Analysis report compares two sets of scan results and shows the difference in URLs and/or security issues that were discovered in them.

About this task

You select Base and Target scans, and AppScan® compares the two sets of results to let you review how the security situation has improved or deteriorated between time of the two scans.

You can compare the currently loaded scan with a saved scan, or you can compare two saved scans.

When comparing scans you will generally use the earlier scan as the Base scan. The Delta Analysis report will then indicate how the Target scan results differ from those of the Base scan.

Delta Analysis reports include the following sections:

Section Title
