Vulnerability categories

Every vulnerability is mapped to one vulnerability category. This includes vulnerabilities, potential vulnerabilities and information gathered checks. When a vulnerability matches multiple categories, our service determines which category is the best match and assigns the vulnerability to that category.

There are currently 30 vulnerability categories available in the KnowledgeBase and new categories are added frequently. Some vulnerability categories are platform-specific (for example Debian and SUSE) while others are more general (for example Database and Firewall). Learn more

When vulnerability categories were first introduced in the product, most of the vulnerabilities in the KnowledgeBase were remote detections which were initially mapped to general categories like Database, Mail Services and Firewall. When authenticated scanning functionality was introduced, several platform-specific vulnerabilities were added to the KnowledgeBase and platform-specific categories were created to coincide with these new detections.
