The Top Cyber Threats CISOs Must Address in DoD Contracting

MAD SEC FT IMAGE - Insider Threats and CMMC - How DoD Contractors Can Protect CUI and Stay Compliant (1)As a CISO in the DIB, your security strategy must extend beyond protecting your organization, it must also ensure the integrity of the entire supply chain. Adversaries are targeting DoD contractors to steal sensitive defense information and to exploit vulnerabilities in third-party vendors and subcontractors. 

 

MAD SEC - Website Images-1Advanced Persistent Threats (APTs) and Nation-State Cyber Espionage

Foreign adversaries, particularly China, Russia, Iran, and North Korea, actively conduct long-term cyber espionage campaigns against DoD contractors. These Advanced Persistent Threats (APTs) infiltrate DIB networks to: 

  • Steal Controlled Unclassified Information (CUI) and defense intellectual property 
  • Compromise supply chains to gain indirect access to the DoD 
  • Deploy stealthy malware and backdoors for long-term reconnaissance 

CISO Response Strategy: 

  • Implement Continuous Threat Monitoring – Deploy Security Information and Event Management (SIEM) tools with 24/7 Security Operations Center (SOC) coverage 
  • Adopt a Zero Trust Security Model – Require strict identity verification, least privilege access, and micro-segmentation 
  • Utilize Behavioral Analytics and AI Threat Detection – Leverage User and Entity Behavior Analytics (UEBA) to detect anomalous insider behavior linked to APT activity 
  • Key Compliance Tie-In NIST 800-171 and CMMC 2.0 Level 2 require contractors to enforce continuous monitoring and access controls to defend against APTs 

MAD SEC - Website Images (1)Ransomware and Double-Extortion Attacks

Ransomware has become a top cyber threat in the DIB, with attackers targeting DoD contractors to encrypt critical data and demand payment. However, modern ransomware attacks go beyond encryption; attackers now exfiltrate data before encrypting it, threatening to leak sensitive DoD-related files if the ransom is not paid (double extortion). 

CISO Mitigation Strategy: 

  • Implement Air-Gapped Backups and Immutable Storage – Ensure data integrity and quick recovery in the event of an attack 
  • Deploy Endpoint Detection and Response (EDR/XDR) – Use AI-driven threat hunting to detect pre-encryption ransomware activity 
  • Enhance Email and Phishing Security Measures – Use DMARC, DKIM, and SPF authentication to reduce ransomware entry points via phishing emails 
  • Key Compliance Tie-In DFARS 252.204-7012 mandates incident response and cyber resilience strategies to counter ransomware threats 

MAD SEC - Website Images (2)Insider Threats in DoD Contracting

One of the most overlooked threats in cybersecurity is insider risk, whether intentional or accidental. In DoD contracting, employees, third-party contractors, or compromised accounts can leak or misuse sensitive data, sometimes without malicious intent. 

CISO Defense Strategy: 

  • Implement Behavioral Analytics for Insider Threat Detection – Use AI-driven tools to detect unusual access patterns, excessive data downloads, or unauthorized credential use 
  • Enforce Zero Trust Access Controls – Restrict access to CUI and mission-critical systems based on job roles 
  • Deploy Continuous User Activity Monitoring – Integrate session recording and access tracking to prevent data exfiltration 
  • Key Compliance Tie-In – CMMC 2.0 Levels 2 and 3 require multi-factor authentication (MFA), role-based access control (RBAC), and continuous monitoring to prevent insider threats 

MAD SEC - Website Images (3)Supply Chain Attacks and Third-Party Risk

Your organization’s cybersecurity is only as strong as its weakest link, and for many DoD contractors, that weakest link is often a third-party vendor with inadequate security controls. Cybercriminals specifically target subcontractors who may have access to DoD systems but lack robust security postures.

CISO Action Plan for Supply Chain Security:

  • Implement a Vendor Risk Management (VRM) Program – Require third-party risk assessments, security questionnaires, and continuous monitoring of vendor security practices 
  • Require CMMC 2.0 Compliance for Subcontractors – Ensure all vendors handling CUI or Federal Contract Information (FCI) meet CMMC 2.0 security requirements 
  • Mandate Secure Data Sharing Practices – Enforce end-to-end encryption, privileged access management (PAM), and supply chain segmentation 
  • Key Compliance Tie-In – CMMC 2.0 mandates third-party security assessments for all subcontractors handling CUI or FCI 

As a CISO, your cybersecurity strategy must go beyond compliance. It must be proactive, threat-driven, and adaptive to evolving risks. The threats facing DoD contractors from APTs to ransomware to insider threats require a multi-layered security approach that integrates: 

  • Zero Trust architecture 
  • Continuous monitoring and threat detection
  • Robust vendor risk management 
  • Automated compliance tracking 

Understanding these top threats and implementing effective mitigation strategies is essential for safeguarding sensitive defense data and maintaining compliance with DoD regulations. 

Regulatory Compliance: What CISOs Need to Know to Stay Audit-Ready

For CISOs in the Defense Industrial Base, maintaining regulatory compliance is not just about avoiding penalties, it is about protecting national security assets and ensuring contract eligibility. The Department of Defense has set strict cybersecurity compliance requirements to safeguard Controlled Unclassified Information (CUI) and Federal Contract Information (FCI) from cyber threats. 

With the rollout of CMMC 2.0, DFARS 252.204-7012, and NIST 800-171, CISOs must take a proactive approach to compliance or risk losing DoD contracts. Here’s what you need to know to ensure your organization stays audit-ready and meets DoD cybersecurity expectations.
