EPSS
Exploit Prediction Scoring System
Geek Speak:
A data-driven model that estimates the likelihood of a software vulnerability being exploited. It provides a score representing the probability of an exploitation activity being observed within the next 30 days. EPSS is used to complement CVSS, which primarily focuses on vulnerability severity, by providing a threat-based perspective.
Plain English:
What Is the Exploit Prediction Scoring System (EPSS)?
The Exploit Prediction Scoring System, or EPSS, is a tool that helps predict how likely a security vulnerability is to be actively exploited by hackers.
Think of it as a weather forecast, but for cyber threats — EPSS scores vulnerabilities based on factors such as how easy they are to attack and how attractive they are to hackers. A higher score means there’s a greater chance someone will try to exploit that weakness.
This helps businesses and security teams prioritize which vulnerabilities to fix first, focusing their efforts on the most dangerous threats.
In simple terms, EPSS helps companies stay one step ahead by predicting where cyber attackers might strike next.
