Art Manion, Principal Engineer at the CERT Coordination Center, joins Jake Kouns, General Manager of Risk Based Security at Flashpoint to talk about vulnerability prioritization, CVSSv4, and how organizations can cope with the increasing number of vulnerability disclosures.

Vulnerabilities are not slowing down. Our VulnDB team aggregated 17,129 vulnerabilities disclosed during the first three quarters of 2020, marking a 4.6% gap when compared to last year. However, earlier in 2020 that gap was instead a sharp decline of 19.2%.

One of the main factors responsible for the rapidly closing gap are the Vulnerability Fujiwhara events and increasing Patch Tuesday releases. With the deluge of vulnerabilities hitting vulnerability management teams, it can be hard to keep up. What can organizations do?
