  1. From the title of your article and your executive summary, the premise of your paper is that CVSS is flawed, and CITE is your solution.
  2. From the title of your article, and choice of name, “QHE CVSS Alternative; CITE”. CVSS is a VULNERABILITY Scoring System. CITE, as your propose, is a THREAT evaluation tool. You can see how one could have the impression that they were incorrectly being used interchangeably.

As you yourself stated, CVSS does exactly what it says on the box. It provides a singular rating for a software vulnerability, in a vacuum. It does not prescribe to do anything more, and it does a good job doing what it sets out to do (including specifically as an input to other quantitative risk calculations).

Compare what with attack?

Your methodology heavily relies on “the analysis of cybersecurity experts”, and in particular, frequently references “exploit chains”, mappings which are not clearly defined, and appears to rely on the knowledge of the individual practitioner, rather than existing open frameworks. MITRE ATT&CK and CAPEC already provide such a mapping, as well as a list of threat actor groups leveraging tactics, techniques, and procedures (e.g., exploitation of a given CVE). Here’s a good articlewhich maps similarly to how we operate our cybersecurity program.

I think there is a lot on the mark in your article about the issues with cybersecurity today, but again, I believe that your premise that CVSS needs replacing is flawed, and I don’t think you provided a compelling case to demonstrate how/why it is flawed. If anything, I think you would agree that if organizations are exclusively using CVSS scores to prioritize remediation, they’re doing it wrong, and fighting an impossible battle. But this means the organization’s approach is wrong, not CVSS itself.

Your article stands better alone as a proposal for a methodology for quantifying risk and threat to an organization (or society?), rather than as a takedown of CVSS.

Ah, much better. MITRE CWSS + CWARF is comprehensive, yet insular and as is MITRE, Military/NATSEC Focused. I do not see any flaws in my reasoning, but words as communication. I do concede that maybe my saying an alternative to CVSS is not really the best wording as I see such things in very broad terms, but I get the perspective now. As in, the common singular, Gov/Corp system does not fit, I need an alternative model that does. In contrast to I need another exactly scoped system that does it differently alternative.

To evidence this I can point to that fact that I even advocated that CVSS-BTE v4.0 should be NVD baseline, but I didn't make this very clear that I'm expanding the CVSS as an alternative use, different in applicability, essential in nature, and somewhat built upon CVSS and OWASP with a different, very important objective.

Not replacment which I never intended.. I'll change the article to reflect those views, well done.
