The Department of Defense (DoD) released its 2024 Defense Industrial Base (DIB) Cybersecurity Strategy, emphasizing routine compliance evaluations to bolster the security of contractors handling sensitive data. This aligns with the Cybersecurity Maturity Model Certification (CMMC) 2.0’s goal of ensuring robust cybersecurity through continuous oversight, with assessments starting in Q1 2025. For DoD and Intelligence Community (IC) contractors, managed IT services are essential to maintain compliance, secure Controlled Unclassified Information (CUI), and meet DoD audit requirements. This blog post explores the role of managed IT in strengthening DIB security, highlights the importance of continuous monitoring, and provides practical strategies to support CMMC Level 2 compliance and ongoing audits.
The DoD’s Push for DIB Cybersecurity
The 2024 DIB Cybersecurity Strategy outlines a proactive approach to securing the supply chain, with routine compliance evaluations as a cornerstone. This complements CMMC 2.0, which requires contractors handling CUI to implement 110 NIST SP 800-171 controls, verified through third-party assessments and maintained via annual affirmations. Key aspects include:
- Continuous Monitoring: Contractors must actively monitor systems to detect threats and ensure controls remain effective.
- Routine Audits: DoD evaluations will check compliance with CMMC and DFARS 252.204-7012, focusing on CUI protection.
- Supply Chain Security: Subcontractors and partners must also maintain robust cybersecurity to prevent vulnerabilities.
Managed IT services provide the tools and processes needed to meet these demands, ensuring contractors remain compliant and secure.
Why Managed IT Is Essential
Without consistent IT management, contractors risk non-compliance, vulnerabilities, and audit failures, leading to:
- Loss of contract eligibility due to unmet CMMC 2.0 requirements.
- Data breaches exposing CUI, compromising national security.
- Operational disruptions from unpatched systems or undetected threats.
- Increased audit scrutiny, as DoD prioritizes routine evaluations.
Managed IT enables continuous monitoring, proactive maintenance, and compliance readiness, strengthening DIB security while freeing contractors to focus on mission-critical tasks.
Strategies for Strengthening DIB Security with Managed IT
Contractors can leverage managed IT to achieve CMMC Level 2 compliance, support DoD audits, and secure CUI with the following strategies:
1. Assess Cybersecurity Needs
A thorough assessment identifies the IT management requirements for CMMC 2.0 and DIB security:
- Map CUI Systems: Identify all systems, networks, and applications handling CUI to determine monitoring and maintenance needs.
- Evaluate Threats: Analyze risks like phishing, ransomware, or insider threats to prioritize IT controls, such as logging or endpoint protection.
- Review NIST Controls: Assess current practices against the 110 NIST SP 800-171 controls to pinpoint gaps in monitoring or management.
This assessment guides the development of a tailored managed IT strategy.
2. Develop a Continuous Monitoring Plan
Continuous monitoring is a core CMMC requirement, ensuring systems remain secure and compliant:
- Deploy Security Tools: Use security information and event management (SIEM) systems or log aggregators to track user activity, system events, and potential threats.
- Set Alert Thresholds: Configure alerts for anomalies, such as unauthorized access or unusual data transfers, to enable rapid response.
- Schedule Reviews: Analyze logs and security reports weekly to identify issues, supporting audit and accountability controls.
- Automate Monitoring: Leverage automated tools to reduce manual effort, ensuring consistent oversight without overburdening staff.
A monitoring plan aligns with NIST controls and prepares contractors for DoD evaluations.
3. Maintain Systems with Proactive IT Management
Proactive maintenance keeps systems compliant and secure, addressing key NIST controls:
- Patch Regularly: Apply software and firmware updates promptly to close vulnerabilities, meeting system and information integrity requirements.
- Manage Configurations: Ensure systems adhere to secure baselines, such as disabling unnecessary services or enforcing encryption, to comply with configuration management controls.
- Secure Endpoints: Deploy antivirus, intrusion detection, and device management to protect against malware and exploits.
- Back Up CUI: Store encrypted backups in CMMC-compliant environments to support recovery and media protection controls.
These practices prevent disruptions and provide evidence for audits.
4. Leverage Microsoft 365 GCC High for Managed IT
Microsoft 365 GCC High is a DoD-compliant cloud platform that enhances managed IT for CMMC 2.0:
- Monitor Security: Use GCC High’s admin center to track user activity, access attempts, and DLP policy violations, supporting continuous monitoring requirements.
- Automate Compliance: Enable automated patching, logging, and configuration checks to maintain NIST controls like audit logging and system integrity.
- Secure CUI Workflows: Restrict sharing in Teams and OneDrive to authorized users, ensuring CUI protection during collaboration.
- Review Logs: Analyze GCC High’s audit logs regularly to detect threats or non-compliance, preparing for DoD evaluations.
GCC High streamlines IT management while aligning with multiple CMMC controls.
5. Refine Compliance Documentation
Managed IT supports the documentation needed for CMMC assessments and DoD audits:
- Update the System Security Plan (SSP): Document how managed IT practices, like monitoring or patching, meet NIST SP 800-171 controls.
- Maintain a Plan of Action and Milestones (POA&M): Track and resolve any control gaps, such as incomplete logging, with clear timelines and responsibilities.
- Collect Evidence: Store logs, patch records, and configuration reports in a centralized system for easy access during audits.
- Review Annually: Ensure documentation reflects current IT practices and monitoring activities to support annual affirmations.
Accurate documentation demonstrates compliance readiness and simplifies evaluations.
6. Prepare for CMMC Assessments and DoD Audits
Managed IT practices ensure systems are audit-ready for CMMC Level 2 and DoD evaluations:
- Conduct Internal Audits: Use managed IT tools to test controls against NIST SP 800-171, identifying gaps in monitoring or maintenance.
- Organize Evidence: Compile logs, SSPs, POA&Ms, and configuration records in a secure, accessible format for C3PAOs or DoD auditors.
- Simulate Evaluations: Practice responding to auditor inquiries about monitoring, patching, or incident response to build confidence.
- Remediate Issues: Address findings from internal audits promptly to avoid delays during official assessments.
Proactive preparation ensures success in both CMMC and DoD audits.
7. Build a Culture of Continuous Compliance
Managed IT fosters ongoing compliance to meet CMMC 2.0 and DIB Cybersecurity Strategy goals:
- Train Staff: Educate employees on secure practices, such as recognizing phishing or reporting incidents, to meet awareness and training controls.
- Test Incident Response: Regularly simulate cyber incidents to refine response plans, ensuring compliance with incident reporting requirements.
- Monitor DoD Updates: Stay informed on CMMC and DFARS changes via DoD resources or industry forums to adapt IT practices.
- Engage Subcontractors: Verify that supply chain partners use managed IT to maintain CMMC compliance, reducing DIB vulnerabilities.
Continuous compliance ensures long-term security and audit readiness.
Looking Ahead: Managed IT and DIB Security in 2025
As CMMC 2.0 assessments and DoD evaluations ramp up, contractors should anticipate:
- Mandatory Compliance: Contracts will require CMMC Level 2 certification, with routine audits verifying continuous monitoring.
- Evolving Threats: State-sponsored cyberattacks will demand robust managed IT to detect and respond to sophisticated threats.
- Supply Chain Focus: DoD will scrutinize subcontractor cybersecurity, requiring coordinated IT management across the DIB.
Proactive managed IT practices position contractors to meet these challenges effectively.
Conclusion
The DoD’s 2024 DIB Cybersecurity Strategy and CMMC 2.0 underscore the critical role of managed IT in strengthening DIB security. By assessing cybersecurity needs, developing monitoring plans, leveraging Microsoft 365 GCC High, and preparing for assessments, contractors can achieve CMMC Level 2 compliance and support routine DoD audits. These strategies not only ensure compliance but also protect CUI, enhance supply chain resilience, and safeguard national security in an increasingly complex threat landscape.
