Which of the following are the three metrics used to determine a cvss score?
Organizations need to identify, prioritize, and remediate these vulnerabilities as soon as possible.
Show CVSS is a free and open industry standard for assessing the severity of computer system security vulnerabilities. It produces a numerical score to rank vulnerabilities based on their severity. Organizations can prioritize their vulnerabilities based on whether the CVSS score risk is low, medium, or high The non-profit Forum of Incident Response and Security Teams (FIRST) owns and manages CVSS. Many organizations have adopted CVSS, including the United States Department of Homeland Security, the United States Computer Emergency Response Team, Amazon, Cisco, HP, Huawei, IBM, McAfee, Oracle, Qualys, and SAP. CVSS v2 vs. CVSS v3: What Is the Difference?The National Infrastructure Assurance Council (NIAC) first introduced CVSS in 2005, and In 2007, released CVSS v2 to better reflect the wide range of vulnerabilities. CVSS v3 was introduced in June 2015, introducing scoring changes to reflect how to discover real-world vulnerabilities more accurately. CVSS v3.1 was released in 2019, clarifying that CVSS v3.1 measures a vulnerability's severity, not its risk. Organizations calculate CVSS scores based on metrics categorized into three groups from which different scores are derived. These metric groups include: Base Metrics The Base Metric Group represents a vulnerability's inherent characteristics, i.e., those that don't change over time or across different user environments. Organizations use the corresponding CVSS Base Score as a key metric of vulnerabilities' severity. It allows them to gauge the vulnerabilities' impacts on their systems and prioritize which to patch first. The Base Metric Group contains several metrics that together create a CVSS Base Score. These metrics are:
The base metrics produce a score between zero (the lowest amount of risk) and ten (the highest amount of risk). Organizations can modify the base metrics by scoring the temporal and environmental metrics. Temporal Metrics Temporal metrics change over time, measuring a vulnerability's current state and the availability of patches. The three metrics in this group are: exploit code maturity, remediation level, and report confidence.
Environmental Metrics Environmental metrics allow organizations to modify the base CVSS metrics based on specific business factors that might increase or decrease a vulnerability's severity. Environmental metrics consist of modified base CVSS metrics and security requirements:
CVSS vs CVECVSS and CVE are complementary standards but not directly related.
Limitations of CVSSIt is important to realize that publicly available CVSS scores do not include the full CVSS metric. They only reflect the Base Score. This is a generic metric that measures how dangerous a vulnerability is, but does not quantify the specific risk it poses to your company. If you run a vulnerability scan, chances are you will find a large number of vulnerabilities, many of them with high CVSS Base Score. The question is - which of these can really result in a damaging security breach in your specific context? Understanding the impact within your environment requires the other elements of the CVSS metric - Temporal and Environmental Factors. Adding these factors requires in-depth knowledge of your organization, its technology stack, and the specific risks it is facing. So it is important to complement raw CVSS scores with additional insights derived from threat modeling and a risk-based analysis of your IT environment.
