Understanding Compliance to Risk Management Controls for CMMC 2.0
How Does Risk Management Fit into CMMC 2.0 Compliance?
Risk management is a fundamental aspect of cybersecurity compliance. The DoD requires organizations to proactively identify, assess, and mitigate security risks to protect CUI. The Risk Assessment (RA) family of controls in CMMC 2.0 ensures that companies can:
- Identify potential security threats before they lead to breaches
- Assess the impact and likelihood of risks in their IT environment
- Conduct vulnerability scanning to detect weaknesses in security controls
- Remediate vulnerabilities to maintain a secure infrastructure
To comply with risk management controls under CMMC 2.0, organizations must implement three key security measures:
- Risk Assessments (RA.L2-3.11.1) – Evaluating security threats and vulnerabilities
- Vulnerability Scanning (RA.L2-3.11.2) – Identifying security gaps in systems and networks
- Vulnerability Remediation (RA.L2-3.11.3) – Fixing vulnerabilities and mitigating risks
Failure to comply with these controls could result in data breaches, loss of DoD contracts, and potential legal repercussions. In the following sections, we will explore each of these risk management controls in detail and provide actionable steps for achieving compliance.
RA.L2-3.11.1 – Conducting Risk Assessments for CMMC 2.0 Compliance
A risk assessment is the foundation of a strong cybersecurity strategy. It helps organizations identify potential threats, vulnerabilities, and risks that could compromise the security of their IT infrastructure. Under CMMC 2.0 (RA.L2-3.11.1), organizations must conduct regular risk assessments to evaluate their cybersecurity posture and implement corrective actions.
What Is a Risk Assessment?
A risk assessment is a structured approach to identifying and evaluating cybersecurity risks that could affect an organization's operations, data security, and compliance. The primary goals of a CMMC 2.0 risk assessment are:
- Identifying potential cybersecurity threats (e.g., malware, insider threats, supply chain risks)
- Evaluating vulnerabilities in systems, networks, and applications
- Assessing the impact and likelihood of risks affecting Controlled Unclassified Information (CUI)
- Developing risk mitigation strategies to reduce the likelihood of cyber incidents
- Maintaining compliance with DoD security regulations
A well-executed risk assessment provides visibility into an organization’s security weaknesses, allowing proactive measures to be taken before threats materialize.
How to Conduct a Risk Assessment for CMMC 2.0
To comply with RA.L2-3.11.1, organizations must follow a structured risk assessment process. Below is a step-by-step guide to performing a CMMC-compliant risk assessment:
1. Identify and Classify Assets
- Create an inventory of critical IT assets (servers, workstations, cloud services, databases)
- Identify which systems store or process Controlled Unclassified Information (CUI)
- Classify assets based on risk levels (high, medium, low)
2. Identify Potential Threats
- External threats – Cyberattacks, malware, ransomware, phishing, nation-state actors
- Internal threats – Insider threats, employee negligence, misconfigurations
- Environmental threats – Natural disasters, power outages, hardware failures
3. Assess Vulnerabilities
- Conduct vulnerability scans to detect weaknesses in network security
- Review software patches and outdated systems for security gaps
- Evaluate misconfigurations in cloud environments and access controls
4. Determine Risk Impact and Likelihood
Use a risk matrix to assess the probability and potential damage of threats:
5. Prioritize and Mitigate Risks
- Develop a Risk Treatment Plan to address high-risk vulnerabilities first
- Apply patches and security updates to critical systems
- Implement multi-factor authentication (MFA) and access controls
- Educate employees through security awareness training
6. Document Findings and Maintain Compliance
- Keep detailed records of risk assessments for CMMC 2.0 audits

A well-executed risk assessment is not just a compliance requirement—it is a proactive security measure that helps organizations stay ahead of cyber threats and protect Controlled Unclassified Information (CUI) from potential breaches.
RA.L2-3.11.2 – Vulnerability Scanning in CMMC 2.0
Vulnerability scanning is a critical component of CMMC 2.0 compliance that helps organizations identify security weaknesses in their IT infrastructure before they can be exploited by attackers. Under RA.L2-3.11.2, organizations must implement regular vulnerability scans to detect and mitigate security risks in networks, applications, and systems that handle Controlled Unclassified Information (CUI).
A well-executed vulnerability scanning program ensures that organizations can proactively address security flaws before they lead to data breaches or compliance violations.
What Is Vulnerability Scanning?
Vulnerability scanning is an automated process that detects security weaknesses in an organization’s IT environment. The goal is to identify misconfigurations, unpatched software, and known vulnerabilities that could be exploited by cybercriminals.
A vulnerability scan does not actively exploit weaknesses but analyzes systems for potential risks based on a database of known vulnerabilities, such as the Common Vulnerabilities and Exposures (CVE) database maintained by MITRE.
Key characteristics of vulnerability scanning include:
- Automated security assessments to detect misconfigurations and missing patches
- Comprehensive network and application scanning for known vulnerabilities
- Risk classification of identified security flaws based on severity
- Actionable remediation guidance for IT and security teams
Unlike penetration testing, which simulates cyberattacks, vulnerability scanning is a non-intrusive method used to identify security gaps efficiently and is a requirement under CMMC 2.0 RA.L2-3.11.2.
How to Perform Vulnerability Scanning for CMMC 2.0 Compliance
To comply with CMMC 2.0 RA.L2-3.11.2, organizations must establish a structured vulnerability scanning program that includes the following steps:
1. Define the Scope of the Scan
- Identify all systems, networks, and applications that store or process CUI
- Determine whether scanning will include internal systems, external-facing assets, or both
- Document the scope and purpose of each scan in security policies
2. Select a Vulnerability Scanning Tool
- Choose a CMMC-compliant scanning tool that meets security requirements
- Consider on-premises vs. cloud-based scanning solutions based on your infrastructure
3. Schedule Regular Scans
- Conduct monthly or quarterly scans for internal and external assets
- Perform ad-hoc scans after significant system updates or security incidents
4. Analyze Scan Results
- Prioritize vulnerabilities based on severity and potential impact
- Identify misconfigurations, outdated software, and unpatched systems
- Validate scan findings to ensure false positives are excluded
5. Remediate Identified Vulnerabilities
- Apply security patches and updates to fix critical vulnerabilities
- Implement compensating controls for risks that cannot be immediately patched
- Document remediation steps for CMMC 2.0 audit compliance
6. Conduct Follow-Up Scans
- Verify that previous vulnerabilities have been fixed
- Monitor for newly discovered vulnerabilities
- Maintain detailed logs of scan results and remediation efforts
By following this structured approach, organizations can maintain CMMC 2.0 compliance while proactively securing their IT environment.
Types of Vulnerability Scans
Different types of vulnerability scans serve various security functions within an organization’s risk management strategy:
Organizations should use a combination of these scans to ensure comprehensive security coverage.
Frequency and Scope of Vulnerability Scans
Organizations must define how often vulnerability scans should be conducted based on their risk exposure and compliance requirements. Below is a recommended frequency schedule:
By following this best practice, organizations can identify security risks early, reducing the likelihood of data breaches and cyberattacks.
Reporting and Documenting Vulnerability Scan Results
To comply with CMMC 2.0 audits, organizations must document their vulnerability scanning processes and results.
Key documentation elements include:
- Scan reports detailing identified vulnerabilities and risk levels
- Mitigation records outlining remediation actions taken
- Evidence of patch implementation and security updates
- Risk acceptance documentation for vulnerabilities that cannot be remediated immediately
These reports should be stored securely and made available for CMMC audits to demonstrate continuous compliance.
Best Practices for Vulnerability Scanning Compliance
To maintain CMMC 2.0 compliance and ensure effective vulnerability management, organizations should:
- Conduct vulnerability scans regularly to detect new security risks
- Prioritize critical vulnerabilities using risk-based methodologies
- Automate scanning to reduce manual errors and increase efficiency
- Integrate scanning results into an incident response plan
- Keep detailed audit logs to demonstrate compliance during CMMC assessments
A robust vulnerability scanning strategy is essential for identifying and addressing security weaknesses, ensuring compliance with RA.L2-3.11.2, and protecting Controlled Unclassified Information (CUI) from cyber threats.
RA.L2-3.11.3 – Vulnerability Remediation and Risk Mitigation
Identifying vulnerabilities through scanning is only the first step in a strong cybersecurity strategy. To achieve compliance with CMMC 2.0, organizations must also take action to remediate those vulnerabilities effectively. The requirement under RA.L2-3.11.3 ensures that organizations fix identified weaknesses in a timely manner to reduce security risks.
Without proper remediation, vulnerability scans provide little security value. Attackers constantly look for known weaknesses to exploit, and unpatched vulnerabilities are among the leading causes of cyberattacks. By implementing a structured approach to remediation, organizations can protect sensitive information and maintain compliance.
What Is Vulnerability Remediation?
Vulnerability remediation is the process of identifying, prioritizing, and resolving security weaknesses found in an organization’s IT environment. The goal is to eliminate or mitigate risks before they can be exploited.
There are three main approaches to handling vulnerabilities:
- Remediation – Fixing the vulnerability entirely, such as by applying a security patch.
- Mitigation – Reducing the impact of a vulnerability if it cannot be fully fixed, such as by restricting access.
- Acceptance – Acknowledging a low-risk vulnerability and choosing not to fix it, typically documented as an informed business decision.
CMMC 2.0 emphasizes remediation as the preferred approach, but in some cases, mitigation or risk acceptance may be necessary when a full fix is not immediately available.
Steps to Remediate Vulnerabilities Effectively
Organizations should establish a structured remediation process to ensure that security weaknesses are addressed efficiently. Below is a step-by-step approach to meeting the RA.L2-3.11.3 requirement.
1. Identify and Analyze Vulnerabilities
- Review vulnerability scan reports to understand security weaknesses.
- Determine the root cause of each vulnerability (outdated software, misconfiguration, weak authentication, etc.).
- Verify findings to rule out false positives.
2. Prioritize Based on Risk
- Use a risk-based approach to address critical vulnerabilities first.
- Consider factors such as:
- The severity score (Common Vulnerability Scoring System – CVSS).
- The exploitability of the vulnerability (how easy it is to attack).
- The potential impact on systems handling Controlled Unclassified Information (CUI).
- High-risk vulnerabilities should be patched immediately, while low-risk ones can be scheduled for later updates.
3. Apply Security Fixes and Updates
- Install software patches from vendors as soon as they are available.
- For vulnerabilities caused by misconfigurations, update system settings to secure them.
- If a patch is not available, implement temporary workarounds such as disabling vulnerable features.
4. Conduct Post-Remediation Testing
- After remediation, perform validation scans to confirm that vulnerabilities have been successfully fixed.
- Conduct penetration testing if necessary to ensure security improvements are effective.
- Document test results for compliance audits.
5. Maintain Continuous Monitoring and Improvement
- Regularly update security policies to reflect lessons learned from past vulnerabilities.
- Conduct ongoing vulnerability scanning to detect new risks.
- Train IT staff on best practices for vulnerability management to prevent recurring security issues.
Prioritizing Vulnerabilities for Remediation
Since not all vulnerabilities pose the same level of risk, organizations should follow a structured approach to determine which ones need immediate attention. The table below provides a general guideline for prioritization.
A well-structured remediation plan ensures that limited resources are allocated effectively to the most pressing security risks.
Challenges in Vulnerability Remediation
Many organizations struggle with timely remediation due to various challenges. Some common roadblocks include:
- Delayed patches from software vendors – Some vulnerabilities remain unpatched for long periods, requiring mitigation strategies.
- Lack of IT resources – Smaller teams may struggle to patch all identified vulnerabilities promptly.
- Operational concerns – Applying patches may cause system downtime, requiring careful scheduling.
- False positives – Some vulnerability scanners produce inaccurate results, leading to wasted efforts on non-existent risks.
To overcome these challenges, organizations should automate as much of the process as possible, use reliable security tools, and ensure that remediation efforts align with business needs.
Best Practices for Vulnerability Remediation and Risk Mitigation
To meet the requirements of RA.L2-3.11.3 and strengthen cybersecurity posture, organizations should follow these best practices:
- Automate patch management to reduce human error and improve efficiency.
- Regularly test security controls to ensure vulnerabilities are being effectively addressed.
- Document all remediation efforts to provide evidence for compliance audits.
- Integrate vulnerability management into an incident response plan to prepare for future threats.
- Ensure accountability by assigning clear roles and responsibilities for remediation tasks.
By embedding vulnerability remediation into ongoing cybersecurity efforts, organizations can maintain compliance with CMMC 2.0 and reduce their exposure to security threats.
