AppScan® Source trace
With AppScan® Source trace, you can verify input validation and encoding that meets your software security policies. You can look at the findings that produce input/output traces and mark methods as validation and encoding routines, sources or sinks, callbacks, or taint propagators.
AppScan® Source trace scan results
Scan results may include traces identified by AppScan® Source trace. The icon in the Trace column indicates the existence of a trace of the call graph.

- Scanning source code and managing assessments
  This section explains how to scan your source code and manage assessments.
- Triage and analysis
  Grouping similar findings allows security analysts or IT auditors to segment and triage source code problems. This section explains how to triage AppScan® Source assessments and analyze results.

    - Validation and encoding
    - Searching AppScan® Source traces
      If you want to group trace findings, you can search for sources or sinks. This causes the trace findings to appear in the Search Results view.
  - Input/output tracing
    An input/output trace is generated when AppScan® Source for Analysis can track the data from a known source to a sink or lost sink.
  - Using the Trace view
  - Validation and encoding scope
    From the Trace view, you can specify custom validation and encoding routines that, once stored in the AppScan® Source Security Knowledgebase, marks data as checked instead of tainted. With the Custom Rules Wizard, you define these routines based on their scope.
  - Creating custom rules from an AppScan® Source trace
    You can create custom rules from the Trace view that allow you to filter out findings with traces that are taint propagators, not susceptible to taint, or sinks. You can also mark methods in the trace as validation/encoding routines (or indicate that they are not validation/encoding routines).
  - Code examples for tracing
    This section provides code examples which illustrate tracking tainted data from a source to a sink - and how to create a validation and encoding routine.
- AppScan® Source for Analysis and defect tracking
  AppScan® Source for Analysis integrates with defect tracking systemsIBM® Rational Team Concert™ to deliver confirmed software vulnerabilities directly to the developer desktop. Defect submission to a defect tracking system contains a textual description of the bug and a file that contains only the findings submitted with the defect.
- Findings reports and audit reports
  Security analysts and risk managers can access reports of select findings or a series of audit reports that measure compliance with software security best practices and regulatory requirements. This section explains how to create reports of aggregate finding data.
- Creating custom reports
  In the Report Editor, you create report templates used to generate custom reports.

AppScan® Source trace scan results

Scan results may include traces identified by AppScan® Source trace. The icon in the Trace column indicates the existence of a trace of the call graph.

Scans may generate findings of type Validation.Required and Validation.EncodingRequired. These findings indicate a location in the source code where data is read from an external source or saved to an external sink. The scan flags these cases because the data should be validated or encoded to prevent malicious or erroneous data from doing harm.
