An industry standard for grading the threat of potential security attacks aims to help users judge more easily the vulnerability of their systems.
The Common Vulnerability Scoring System (CVSS) is designed to replace the different security threat rating systems currently used by individual suppliers.
The US-based Forum of Incident Response and Security Teams is promoting adoption of CVSS, which has been developed over the last year by various firms, including Cisco.
Along with Cisco, the likes of Symantec, Internet Security Systems and Qualys back the adoption of CVSS for supplier security rating systems.
The system is set to include a set of criteria to allow firms to decide more accurately which patches are the most urgent to install, over and above the established “important” and “critical” ratings popular with large suppliers like Microsoft.
Microsoft has not so far backed CVSS, so general adoption in main operating systems could be stilted.
