The arrival of the new version of CVSS (Common Vulnerability Scoring System) covers some deficiencies related to the assessment of vulnerabilities in the industrial world. The introduction of changes in the way of scoring different vulnerabilities, the incorporation of new metrics for elements of the industrial world such as "Safety" or the service recovery of a device, are some of the new features introduced in version 4 of the CVSS.
This article will analyze the new features brought by version 4.0 and its increased accuracy when assessing vulnerabilities in industrial environments for a better adequacy of the scores given.
When talking about an endpoint device, we are talking about an end asset present at the network level. Among these devices we can find engineering stations (workstations), HMI, SCADA or PLC, among others.
The evolution of industrial environments towards models in which these equipment are connected, both with corporate networks and remotely with suppliers, for maintenance purposes, exposes them to new threats. That is why industrial endpoints must be properly and individually protected and at multiple levels so that they cannot be compromised. These end systems are key security hotspots because their vulnerabilities could affect other assets within the network.
