IssueSecurity Advisories Severity Rating
ResolutionSeverity Rating
A security vulnerability is classified by its severity rating, which is determined by many factors, including the level of effort required to exploit a vulnerability as well as the potential impact to data or business activities from a successful exploit. RSA currently uses the Common Vulnerability Scoring System version 3.0 (CVSS v3.0) to identify the severity level of identified vulnerabilities. The full standard, which is maintained by the Forum of Incident Response and Security Teams (FIRST), can be found at: https://www.first.org/cvss.
When and where applicable, RSA Security Advisories will provide the CVSS v3.0 Base Score, corresponding CVSS v3.0 Vector and the CVSS v3.0 Severity Rating Scale for identified vulnerabilities. RSA recommends that all customers take into account both the Base Score and any Temporal and/or Environmental Scores that may be relevant to their environment to assess their overall risk.
