Resource created as part of Mari Galloway’s TI Essentials article: “How the BrickHaus CTI team prioritized their vulnerability backlog” | Published April 16, 2026 | feedly.com/ti-essentials/


Here's a checklist with relevant tools/resources that you can use and customize to ensure your CTI team provides effective support for exposure management process.

Step 1: Establish your intelligence foundation

☐ Identify key CTI sources Relevant tools/resources: CISA KEV, EPSS, MITRE ATT&CK, ISACs, MISP, OpenCTI, AlienVault OTX

☐ Subscribe to threat feeds relevant to your industry

☐ Understand what scanners and tools feed your VM team's backlog Relevant tools/resources: TenableVM, Rapid7, Qualys, OpenVAS, OWASP ZAP, Snyk

☐ Establish a recurring sync cadence with VM, SOC, and remediation teams

Step 2: Re-prioritize exposures with threat intel

☐ Cross-reference backlog CVEs against the CISA KEV database Relevant tools/resources: CISA KEV

☐ Pull EPSS scores to gauge exploitation likelihood Relevant tools/resources: EPSS

☐ Check NVD for CVSS scores and additional context Relevant tools/resources: NVD

☐ Identify which threat actors are exploiting the CVE and their TTPs Relevant tools/resources: MITRE ATT&CK Groups, Malpedia

☐ Escalate items the scanner rated MEDIUM if they appear in KEV or carry a high EPSS score Relevant tools/resources: CISA KEV, EPSS

☐ For non-CVE findings (misconfigurations), map flaws to attacker techniques or use STRIDE Relevant tools/resources: MITRE ATT&CK, STRIDE, ScoutSuite

Step 3: Validate risk

☐ Confirm business context for each exposure (asset type, data sensitivity, compliance scope, network location)

☐ Check for related incidents or exploitation reports, internal logs, and external threat reports

☐ Run targeted scans to identify all affected systems, software versions, and exposure duration Relevant tools/resources: TenableVM, Rapid7, Qualys

☐ Assess whether the asset is internet-facing (faster action required regardless of base CVSS) Relevant tools/resources: Shodan (community tier), Censys Search (free tier), GreyNoise (community tier)
