EPSS Intelligence Repository (DarCache EPSS) FAQ
-
An EPSS Intelligence Repository, like ThreatNG's DarCache EPSS, contains data from the Exploit Prediction Scoring System (EPSS). EPSS provides a probability score between 0 and 1 (inclusive) representing the likelihood of a vulnerability being exploited in the wild within a given time frame.
Its general importance stems from its ability to:
Move Beyond Static Severity: Traditional vulnerability scoring systems (like CVSS, part of NVD ) primarily focus on a vulnerability's inherent severity and technical characteristics. While crucial, severity alone doesn't tell you how likely a vulnerability will be actively exploited. EPSS bridges this gap by providing a probability of real-world exploitation.
Enable Predictive Prioritization: Instead of patching everything, which is often impossible due to resource constraints, EPSS allows organizations to prioritize the most likely weaponized vulnerabilities. This shifts the focus from "what's bad" to "what's bad and likely to be used against us."
Optimize Resource Allocation: By highlighting the vulnerabilities with the highest probability of exploitation, EPSS helps security teams allocate their limited resources more effectively. This ensures that efforts are concentrated on the threats that pose the most significant immediate risk.
Serve as an Early Warning System: High EPSS scores can signal an emerging threat, even before a vulnerability is widely known to be actively exploited. This provides an opportunity for proactive defense.
