The CERT Knowledgebase is a collection of internet security information related to incidents and vulnerabilities. The CERT Knowledgebase houses the public Vulnerability Notes Database as well as two restricted-access components:
- Vulnerability Card Catalog [special access required*] contains descriptive and referential information regarding thousands of vulnerabilities reported to the CERT Coordination Center.
Special Communications Database
[special access required*]contains briefs that provide advance warning and important information about vulnerabilities, intruder activity, or other critical security threats.
* With rare exceptions, CERT Knowledgebase access is granted only to employees of the United States Government. Visit the Knowledgebase FAQ for more information about these two websites.
