Why use cwe

It also might make it easier to introduce vulnerabilities. Technical Impact: Reduce Maintainability. CWE is sponsored by the U. CWE Glossary Definition. Weakness ID: Status: Incomplete. Presentation Filter:. The product relies on third-party components that are not actively supported or maintained by the original developer or a trusted proxy for the original developer.

Extended Description. This table shows the weaknesses and high level categories that are related to this weakness. They can all be fit into the normal PLC programming and operating workflow. More than security expertise, good knowledge of the PLCs to be protected, their logic, and the underlying process is needed for implementing these practices.

By aligning CVE Records to the most applicable CWE Entries, the community will be in a better position to mitigate or eliminate their associated operational risk most effectively. Guidance The new guidance provides an overview of CWE , a section of helpful resources with a refresher on CWE Entry structure , and offers five different mapping methodologies that can be used on the CWE website to help identify appropriate weakness mappings for CVE Records:.

A mapping cheat sheet and mapping examples are also included. Feedback Welcome. Please contact us with any comments or concerns about this guidance. March 19, Share this article.

Participants in this free virtual event will have the opportunity to provide feedback on how CWE and the CWE Compatibility program are working for them and their customers. Also, one goal of the Top 25 was to be at a level that is directly actionable to programmers, so it contains more detailed issues than the categories being used in the Top Ten.

There is some overlap however, since web applications are so prevalent, and some issues in the Top Ten have general applications to all classes of software. National Vulnerability Database NVD and developed a scoring formula to calculate a rank order of weaknesses that combines the frequency of a CWE with the projected severity of its exploitation. While this method introduces a bias through analyzing only reported vulnerabilities and could potentially exclude some software and a breadth of other data, the CWE Team believes it will result in a more repeatable and accurate Top 25 list each year.

For detailed information about this new approach, including methodology, rankings, scoring, and refined mappings, visit the CWE Top 25 page.

What types of software and weaknesses are included on the CWE List? What information is included in a CWE weakness entry? Refer to the Schema and Schema Documentation for more information. Is there a glossary or key available to help me understand CWE terminology? See the Schema Documentation for additional information.

Why is there a printable version of the CWE List? What information is included in it? The printable version includes a complete list of all CWE entries from the most current release in numerical order along with a table of contents, an index, and the CWE-ID in the facing margins for easy searching through a printed copy.

Many organizations use printed copies of CWE for design review meetings and training. What do the numerals in parenthesis signify in the various views of the CWE List? How is it used? Development Concepts — This view organizes weaknesses around concepts that are frequently used or encountered in software development. Accordingly, this view can align closely with the perspectives of developers, educators, and assessment vendors.

It provides a variety of categories that are intended to simplify navigation, browsing, and mapping. Research Concepts — This view is intended to facilitate research into weaknesses, including their inter-dependencies, and can be leveraged to systematically identify theoretical gaps within CWE. It classifies weaknesses in a way that largely ignores how they can be detected, where they appear in code, and when they are introduced in the software development life cycle.

Instead, it is mainly organized according to abstractions of software behaviors. This view can be useful to any researcher, educator, software developer, or other organization interested in locating specific weakness types. It can be used to quickly see the structure implied by the parent relationships in those views. Also, some files provide "coverage graphs" in which the members of a smaller view are highlighted within the context of a larger view, illustrating how the entries of the smaller view are organized by the larger view.

What is the difference between an Explicit Slice and an Implicit Slice? How can the various slices under each category help me? An "Explicit Slice" is a view whose membership is determined by some external criterion that is represented using HasMember relationships between the view and those entries, but not between entries themselves. The Composite are those instances in which two or more distinct weaknesses must be present at the same time in order for a potential vulnerability to arise, and where removing any of the weaknesses eliminates or sharply reduces the risk.

By eliminating any single component, a developer can prevent the composite from becoming exploitable. Often the various components of a composite are found in different aspects of a software system, either in the architecture, design, code, or implementation, which means that multiple assessment methods may be needed to find them or that one type of assessment method — like a static analysis tool can find issues in code but not in design, architecture, or implementation.

A "Chain" is a sequence of two or more separate weaknesses that can be closely linked together within software, where one weakness can directly create the conditions that are necessary to cause another weakness. By understanding how one weakness can chain to another weakness and result in another type of weakness, assessment results that show the presence of one of the weaknesses in a chain can now be viewed in light of the possibility that the one weakness discovered could be indicating the presence of the entire chain.

Is there a key to the small icons used in the Type column in the Relationship section of the definition pages? CWSS scores CWEs using 18 different factors across three metric groups: 1 the Base Finding group, which captures the inherent risk of the weakness, confidence in the accuracy of the finding, and strength of controls; 2 the Attack Surface group, which captures the barriers that an attacker must cross in order to exploit the weakness; and 3 the Environmental group, which includes factors that may be specific to a particular operational context, such as business impact, likelihood of exploit, and existence of external controls.

By knowing the severity of weaknesses software developers and organizations that use that software will know which CWEs should have priority in being addressed. In addition, educators teaching software code writing will know which weaknesses should be addressed directly in their curriculum.

CWRAF also enables better informed decision-making for the development and acquisition of more secure and resilient software products and services. In CWRAF, a Business Domains is a major function or service that includes the operations and interactions of a broad range of networked capabilities or organizations from the public and private sector, government and military, commercial and nonprofit organizations, academia, etc.

In CWRAF, an Archetype is general type of technical capability, component, system, system-of-systems, or architecture that is commonly used to support the mission of a particular organization. An archetype may also be used within multiple business domains.
