Common Weakness Enumeration

CWE Glossary Definition

Name of Your Organization:

U.S. National Institute of Standards and Technology (NIST)

Web Site:

www.nist.gov

Compatible Capability:

Software Assurance Reference Dataset (SARD)

Capability home page:

http://samate.nist.gov/SARD/

Product Accessibility <CR_2.4>

Provide a short description of how and where your capability is made available to your customers and the public (required):

NIST's Software Assurance Reference Dataset (SARD) provides a public repository of more than 61,000 test cases for software assurance tool assessment via Internet.

Map Currency Indication <CR_6.1>

Describe how and where your capability indicates the most recent CWE content used to create or update its mappings (required):

The section in the SARD designer's notes that discusses the weakness naming convention and CWE Compatibility states the version of CWE that the software's set of mappings is based on.

Map Currency Update Approach <CR_6.2>

Indicate how often you plan on updating the mappings to reflect the current CWE content and describe your approach to keeping reasonably current with the CWE content when mapping them to your repository (recommended):

When a test case is submitted to the SARD repository, its weakness(es) will be stored, according to the CWE mapping, as part of test case record. If the weakness(es) does not exist in the SARD CWE weaknesses table, the table will be updated accordingly.

When there is a new release of CWE, the CWE mapping will be reviewed and a relevant change will be made if it applies.

CWE AND COMPATIBILITY DOCUMENTATION <CR_5.1>

Provide a copy, or directions to its location, of where your documentation describes CWE and CWE compatibility for your customers (required):

CWE and CWE compatibility are described in a section of the SARD Designer's Notes, titled "Naming Convention of Weakness – CWE Compatibility". It is accessible via http://samate.nist.gov/SARD/.

DOCUMENTATION OF FINDING ELEMENTS USING CWE IDENTIFIERS <CR_5.2>

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):

On the screen of searching test cases, click on the tab of Extended Search. Then, there are two ways presented to search test cases using CWE Identifiers:

• On the right portion of the screen, expand the CWE weaknesses under "Weakness". A hierarchical tree of software weaknesses in CWE Identifiers that SARD supports will display. Selecting one of the CWE Identifier will add that weakness as one of searching criteria. It will show at searching field "Weakness" on the left portion of the screen. Fill in other searching fields on this screen, if applicable. Clicking on "Search Test Cases" will return a list of test cases that meet the searching criteria.

  

  Figure 1: Search Screen using JavaScript tree

• If your browser does not support JavaScript tree, click on "Weakness" will not expand the hierarchical tree of CWE Identifiers. Move the mouse onto "Click here if experiencing some trouble with the JavaScript trees" at the right-upper corner of the screen and click. Then, use the drop down menu of "Weakness" field on the left portion of the screen. The menu has the complete list of CWE Identifiers that SARD supports. Select the desired software weakness from that menu.

DOCUMENTATION OF FINDING CWE IDENTIFIERS USING ELEMENTS <CR_5.3>

Provide a copy, or directions to its location, of where your documentation describes the process a user would follow to find the CWE identifiers associated with individual security elements within your capability's repository (required):

In SARD, the CWE-ID appears in every place where weakness needs to be posted, e.g., the screen display of a test case, in the list of test cases, the output zipped file of test cases, etc. The complete list of CWE weakness used in SARD is provided on line.
