<h1>Understanding Acceptance Levels</h1>
|
||
<p>
|
||
CVMAP has established a set of Acceptance Levels that a CNA can achieve based on the
|
||
data they provide through the CVE List. Acceptance Levels are assigned for each
|
||
submission category and each CNA. This means that a CNA who provides submission
|
||
data for both CVSS v3.1 and CWE could have an Acceptance Level of Reference for
|
||
the CVSS v3.1 submission and an Acceptance Level of Contributor for the CWE
|
||
submission. As CNAs provide submission category data and NVD analysts provide
|
||
analysis results, the CNA provided data is compared against the NVD analyst data.
|
||
As the CNA and NVD data align, the Acceptance Level of the CNA for that submission
|
||
category increases.
|
||
</p>
|
||
<p>
|
||
The goal for all CNAs is to reach the Provider Acceptance Level for the submission
|
||
categories in which they participate. Unlike Reference and Contributor; Provider
|
||
level data is considered equal to that of NVD analysis and is immediately
|
||
placed into the NVD upon reception. Additionally, Provider level data is audited
|
||
at a much lower frequency. A level of Non-Acceptance is reserved for if a CNA’s
|
||
content has been deemed unfit for display on the NVD website and inclusion within
|
||
the NVD data feeds (i.e., content contains classified, offensive, derogatory or
|
||
purposefully misleading content).
