Migrating to the current version of AppScan® Source

HCL licensing

As part of the transition from IBM to HCL, HCL introduced HCL-centric license packages for the AppScan family of products. AppScan products continued to support existing IBM licenses through version 10.0.1. As of version 10.0.2, an HCL license is required.

New licenses are available only through HCL.

To acquire and apply a new AppScan Source license, first obtain the appropriate license through the HCL FlexNet portal, then apply the license using the AppScan Source License Manager.

For additional information, see How to obtain and apply licenses for AppScan Source products.

AppScan® Source interoperability

New rule attributes may result in findings classification changes in existing scans

After Version 9.0.2, Attribute.Likelihood.High and Attribute.Likelihood.Low rule attributes were introduced. When these attributes are used, AppScan® Source can more accurately determine if findings are definitive and/or suspect. As a result, if you scan source code in AppScan® Source Version 9.0.2 or earlier, you may find that some findings classifications will change when the same source code is scanned in product versions after 9.0.2. This will be most noticeable for findings related to highly exploitable web sources - or for property or environment sources that are less exploitable.

These rule attributes are used by default. You can disable them, as follows:

1. Open <data_dir>\config\ipva.ozsettings in a text editor (where <data_dir> is the location of your AppScan® Source program data, as described in Installation and user data file locations). Locate the allow_likelihood setting in the file. This setting will look similar to:

   <Setting
     name="allow_likelihood"
     value="true"
     default_value="true"
     description="Allow the processing of the Likelihood 
       attributes to help determine trace confidence based 
       on the source API"
     display_name="Allow Likelihood"
     type="bool"
   />

   In this setting, modify the value attribute. If the attribute is set to true, this setting will be on. If it is set to false, AppScan® Source will not use these rule attributes during scans.
2. Save the file after you have modified this setting and start or restart AppScan® Source.

Automatic lost sink generation

After Version 9.0.2, automatic lost sink resolution was introduced for traces that end in getters/setters and methods that return boolean values. This is done by automatically inferring markup for these application programming interfaces (API). As a result, if you scan source code in AppScan® Source Version 9.0.2 or earlier, you may notice changes in findings results that contained unresolved lost sinks when the same source code is scanned in product versions after 9.0.2.

Automatic markup generation is on by default. You can disable it if you want to use other means of lost sink resolution such as custom rules, as follows:

1. Open <data_dir>\config\ipva.ozsettings in a text editor (where <data_dir> is the location of your AppScan® Source program data, as described in Installation and user data file locations). Locate the automatic_lost_sink_resolution setting in the file. This setting will look similar to:

   <name="automatic_lost_sink_resolution"
     value="true"
     default_value="true"
     description="This setting tries to perform automatic 
       lost sink resolution by assuming taint propagation 
       for getters, setters and APIs which return boolean 
       with no arguments."
     display_name="Auto Lost Sink Resolution"
     type="bool"
   />

   In this setting, modify the value attribute. If the attribute is set to true, this setting will be on. If it is set to false, AppScan® Source will not automatically generate markup for these methods.
2. Save the file after you have modified this setting and start or restart AppScan® Source.

AppScan® Enterprise Server authentication: Migration considerations for replacement of the IBM® Rational® Jazz™ user authentication component with IBM® WebSphere® Liberty

• Migrating from an Enterprise Server that only has local Jazz™ users: In this upgrade scenario, the former Jazz™ users will appear in the AppScan® Source Database as AppScan® Enterprise Server users, however, they will not be valid. These users can be removed from the Database - or they can be converted to AppScan® Source users. Contact HCL Support for information on enabling former Jazz users in AppScan® Source.
• Migrating from an Enterprise Server that was configured with LDAP: During the Enterprise Server upgrade, you have the option of configuring the Enterprise Server with LDAP again. If you do this, existing users will still work in AppScan® Source.
• Migrating from an Enterprise Server that was configured with Windows™ authentication: If your Enterprise Server was configured with Windows™ authentication, existing users will work in AppScan® Source, provided the new Enterprise Server Liberty is configured to use Windows™ authentication.

Changes to findings classifications

After Version 8.7, findings classifications changed. This table lists the old classifications mapped to the new classifications:

An example of these changes can be seen in the Vulnerability Matrix view.

As of Version 8.8, the view looks like this:

Default settings changes that will improve scan coverage

As of AppScan® Source Version 8.8:

• The default value of show_informational_findings in scan.ozsettings has changed from true to false.
• The default value of wafl_globals_tracking in ipva.ozsettings has changed from false to true. This setting enables AppScan® Source to find dataflow between different components of a framework-based application (for example, dataflow from a controller to a view).

The change to show_informational_findings will result in assessments not including findings with a severity level of Info by default.

Restoring AppScan® Source predefined filters from previous versions

In AppScan® Source Version 8.8, predefined filters were improved to provide better scan results. If you need to continue using the predefined filters from older versions of AppScan® Source (archived filters are listed in AppScan Source predefined filters (Version 8.7.x and earlier)), follow the instructions in Restoring archived predefined filters.
