The Patch Gap: Why Defenders Need to Think in Chains, Not Checklists

The article highlights a significant gap between the speed at which attackers discover and exploit vulnerabilities and the speed at which defenders can patch them. Traditional CVSS-based prioritization is inadequate because attackers are exploiting vulnerabilities before patches are available, and vulnerabilities are often exploited in chains. The recommended approach is to shift from a checklist-based patching strategy to a ‘choke-point patching’ model, which involves modeling attack paths and prioritizing remediation of vulnerabilities that disrupt the most critical attack routes to an organization’s assets. This requires a shift in thinking from individual vulnerability analysis to a broader understanding of how vulnerabilities connect and contribute to a successful attack.
