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 contains descriptive and referential information regarding thousands of vulnerabilities reported to the CERT Coordination Center.
- Special Communications Database 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.
