Provide a copy, or directions to its location, of where your documentation describes the specific details of how your customers can use CWE identifiers to find the individual security elements within your capability’s repository (required):

The mapping between CWE identifier and individual security elements can be accessed in two distinct locations:
1 – as part of the documentation, which can be found on the location described on §6
2 – from the Rule Configuration Dialog in the Project Properties:

CR_5.2: Mapping of CWE-121 against OAC 9.1.0 checks
Figure 1- Mapping of CWE-121 against QAC 9.1.0 checks

The CWE ID(s) referring to the weakness associated with a specific violation is automatically indicated in the diagnostic provided by the tool. In the GUI, this happens in the Analysis/Results Diagnostics Pane, where for each occurrence of a check there is the corresponding ID (or IDs in case of multiple violations) of the CWE violated:

CR_5.3: Message qac-9.1.0-0184 mapped to multiple CWE IDs

Type-Specific Capability Questions

Tool Questions

FINDING TASKS USING CWE IDENTIFIERS <CR_A.2.1>

Give detailed examples and explanations of how a user can locate tasks in the tool by looking for their associated CWE identifier (required):

The GUI allows to filter the analysis results by rule or rule group; since the CWE C compliance module considers CWE Weaknesses as "rules" from the organizational point of view, this allows to isolate all the occurrences of the diagnostics which are referring to the violation of the specific CWE instance:

CR_A.2.1: Filtering on CWE-134 CR_A.2.1: Filtering on CWE-134 CR_A.2.1: Filtering on CWE-134
Figure 3 Filtering on CWE-134

FINDING CWE IDENTIFIERS USING ELEMENTS IN REPORTS <CR_A.2.2>

Give detailed examples and explanations of how, for reports that identify individual security elements, the tool allows the user to determine the associated CWE identifier for the individual security elements in the report (required):

As part of the report production process, the tool generates a results data file in portable format (XML) from which it's possible to extract single occurrences of the analysis checks grouped by CWE element.

GETTING A LIST OF CLAIMED CWE IDENTIFIER COVERAGE <CR_A.2.3>

Give detailed examples and explanations of how a user can obtain a listing of all of the CWE identifiers that the owner claims the tool is effective at locating in software (required):

The list of CWE identifiers and individual security elements mapped to them can be accessed in two distinct locations:
1 – as part of the documentation, which can be found on the location described on §6
2 – from the Rule Configuration Dialog in the Project Properties:

CR_A.2.3: Mapping of CWE-121 against QAC 9.1.0 checks
Figure 4- Mapping of CWE-121 against QAC 9.1.0 checks

The table of CWE Coverage information is also available on the PRQA website
http://www.prqa.com/wp-content/uploads/2016/09/CWE_mapping_2QAC.pdf

GETTING A LIST OF CWE IDENTIFIERS ASSOCIATED WITH TASKS <CR_A.2.6>

Give detailed examples and explanations of how a user can obtain a listing of all of the CWE identifiers that are associated with the tool’s tasks (recommended):

A complete list of the CWE IDs covered by the tool's capabilities are available on the documentation provided with the CWE compliance module, more specifically on sections "5 – Rule Cross Reference" and "6 – Rule Enforcement" of the component manual.

SELECTING TASKS WITH A LIST OF CWE IDENTIFIERS <CR_A.2.7>

Describe the steps and format that a user would use to select a set of tasks by providing a file with a list of CWE identifiers (recommended):

The correspondence between security check and CWE ID impacted is provided by means of configuration files (in the specific case Rule Configuration Files – RCF). Consequently, there's no operation of mapping required to the user to be performed.

SELECTING TASKS USING INDIVIDUAL CWE IDENTIFIERS <CR_A.2.8>

Describe the steps that a user would follow to browse, select, and deselect a set of tasks for the tool by using individual CWE identifiers (recommended):

As described before, there's a predefined set of checks assigned to each CWE IDs covered by the tool. For each CWE IDs there's the possibility to browse, select and deselect checks from the "Project Properties" dialog (accessible from GUI and CLI):

1 – In the "Rule Configuration" tab, select the CWE ID to be modified (e..g CWE-14). The corresponding current mapping will be shown:

CR_A.2.8

2 – Right click and click on "Messages". A "Rule Enforcement Messages" dialog will pop up:

CR_A.2.8

3 – Expanding the "Messages" menu for the the chosen component it's possible to select/unselect single messages. Optional customized messages are available under the "User Messages" menu:
