Security
CVSS
Abbreviation for Common Vulnerability Scoring System
In short and in plain language
CVSS is a system that rates security flaws.
It rates how serious a flaw is from a technical point of view. The result is a value on a fixed scale.
This value is a guide for planning updates. But it does not replace your own view of your shop.
Definition
CVSS is a system that rates security flaws by their technical severity. The result is a numerical value on a fixed scale. For planning updates it is a point of reference, but it does not replace the assessment for your own shop.
