"Revolutionizing Vulnerability Management: Introducing CVSS 4.0 π"
The cybersecurity realm takes a significant leap with the release of CVSS 4.0 by FIRST. This new framework enhances precision in vulnerability assessments, especially for OT/ICS/IoT environments, and introduces new metrics like Automatable and Recovery. A game-changer for security professionals! π‘οΈπ‘
Common Vulnerability Scoring System Version 4.0 (CVSS v4.0) is an updated standard for assessing the severity of security vulnerabilities. Unlike its predecessor, CVSS v4.0 emphasizes that it comprises not only the Base score but also incorporates additional factors.
CVSS v4.0 introduces new terminology, such as CVSS-B, CVSS-BT, CVSS-BE, and CVSS-BTE, to represent various combinations of scores. It provides more precise details with the introduction of new Base metrics like Attack Requirements (AT) and User Interaction (UI) values (Passive and Active).
The impact assessment is refined, separating the impact on Vulnerable Systems and Subsequent Systems. Temporal metrics are now part of the Threat metric group, simplifying the assessment. Remediation Level (RL) and Report Confidence (RC) have been retired, replaced by clearer values in Exploit Maturity (E).
A new Supplemental Metric Group adds extrinsic attributes like Safety, Automatability, Recovery, Value Density, Vulnerability Response Effort, and Provider Urgency. CVSS v4.0 also places more emphasis on Operational Technology (OT), Industrial Control Systems (ICS), and Safety, with assessments for Consumer-assessed Safety and Provider-assessed Safety.
CVSS v4.0 enhances the precision and comprehensiveness of vulnerability assessments, making it a valuable tool for evaluating and prioritizing security risks.
