Communicate to affected personnel
13
Schedule periodic review and updates

Threats & Vulnerabilities (CIS RAM)

Threat Scenarios

Exploitation of Known but Unremediated Vulnerabilities

Confidentiality

Vulnerabilities identified through scanning are documented but never remediated due to lack of a remediation workflow, giving attackers a persistent and growing catalog of known weaknesses to exploit across the environment.

Ransomware Deployment via Long-Standing Unpatched Flaws

Availability

Ransomware groups specifically target organizations with large vulnerability backlogs, exploiting well-known CVEs in VPN appliances, remote desktop services, or web applications that have been detected but left unremediated for months.

Chained Exploit Attacks Using Multiple Unremediated Vulnerabilities

Integrity

Attackers combine multiple lower-severity unremediated vulnerabilities into exploit chains that achieve critical impact, such as combining an information disclosure flaw with a privilege escalation vulnerability to gain administrative access.

Vulnerabilities (When Safeguard Absent)

Growing Vulnerability Backlog with No Remediation Cadence

Detected vulnerabilities accumulate in scan reports without systematic remediation, creating an ever-expanding backlog where even critical vulnerabilities may persist for quarters while teams focus on operational priorities.

No Tooling Integration Between Scanning and Remediation

Vulnerability scan results are not integrated with ticketing or patch management systems, requiring manual transfer of findings that introduces delays, errors, and lost remediation assignments.

Evidence Requirements

Type Evidence Item Collection Frequency
Document Response procedure/playbook documentation Reviewed bi-annually
Record Response action logs showing procedure execution Per incident
Technical Vulnerability scan reports showing scope and findings Per scan cycle
Record Vulnerability remediation tracking with SLA compliance metrics Monthly
Document Governing policy document (current, approved, communicated) Reviewed annually
