Cybersecurity Compliance for US Logistics & Supply Chain

Why US Logistics and Supply Chain Is a Prime Target

US logistics and supply chain organizations operate at the intersection of physical operations, digital freight management systems, and often-classified defense contracts. This convergence creates a broad attack surface. The Colonial Pipeline ransomware attack in 2021, which triggered a TSA emergency directive, demonstrated how a single IT compromise could halt fuel delivery across the Eastern Seaboard. Since then, the threat landscape has become more sophisticated. Ransomware groups specifically target logistics firms to disrupt supply chains and demand larger ransoms. Nation-state actors seek to infiltrate logistics IT systems to map defense supply chains. Insider threats—both malicious and accidental—remain a top concern given the volume of subcontractors and temporary workers in warehousing and distribution.

For US-based logistics firms, the regulatory response has been swift and sector-specific. The Transportation Security Administration (TSA) issued multiple Security Directives for pipeline and rail operators, mandating specific cybersecurity measures including network segmentation, access controls, and incident reporting. The Cybersecurity and Infrastructure Security Agency (CISA) regularly issues alerts targeting logistics IT and operational technology (OT) systems. And the DoD’s CMMC 2.0 program now requires all defense supply chain partners to achieve certification at Level 1 (basic cyber hygiene), Level 2 (NIST 800-171 compliance), or Level 3 (advanced persistent threat protection), depending on the sensitivity of information handled.

Which US Cybersecurity Regulations Apply to Logistics & Supply Chain?

The regulatory framework differs based on the type of logistics operation, the cargo handled, and the customer base. Below are the primary regulations US logistics firms must evaluate:

TSA Security Directives (Pipeline and Rail)

The TSA Security Directives apply to owners and operators of pipeline systems (including hazardous liquid and natural gas pipelines) and freight rail operators. These directives require: (1) implementation of specific cybersecurity measures including network segmentation between IT and OT, (2) establishment of a Cybersecurity Incident Response Plan (CIRP) that aligns with NIST CSF 2.0, (3) mandatory reporting of confirmed cybersecurity incidents to CISA within 24 hours, and (4) third-party validation of security controls through annual assessments. Non-compliance can result in civil penalties up to $1 million per violation and operational restrictions.

CyberSilo’s Threat Exposure Management solution helps pipeline and rail operators continuously map their IT and OT assets, identify gaps against TSA requirements, and automate evidence collection for TSA audits.

CMMC 2.0 (Defense Supply Chain)

Any US logistics firm handling DoD contracts or subcontracts—including freight forwarders transporting defense materials, warehousing firms storing CUI, or logistics IT providers managing defense supply chain data—must achieve CMMC 2.0 certification. Level 2 requires compliance with all 110 security controls in NIST SP 800-171, covering access control, incident response, risk assessment, system and communications protection, and maintenance. Certification must be performed by a CMMC Third-Party Assessment Organization (C3PAO) every three years, with annual self-assessments for Level 1. The DoD has stated it will withhold contract awards from uncertified firms starting in 2026.

NIST SP 800-171 (Protecting CUI)

Even outside of CMMC, any logistics firm that processes, stores, or transmits CUI on behalf of a federal agency must comply with NIST SP 800-171. This standard requires 110 controls across 14 families, with specific requirements for multi-factor authentication (MFA) for network access, encryption of CUI at rest and in transit, and a plan of action and milestones (POA&M) for remediation of control deficiencies. The FAR and DFARS clauses mandate flow-down of these requirements to subcontractors, meaning a 3PL warehousing defense goods must impose the same controls on its subcontracted feeder lines.

For logistics firms supporting multiple federal contracts, CyberSilo’s Compliance Standards Automation platform provides a single dashboard to track compliance across NIST 800-171, CMMC, and TSA frameworks simultaneously, reducing audit preparation time by up to 60%.

CIRCIA (Cyber Incident Reporting for Critical Infrastructure)

The Cyber Incident Reporting for Critical Infrastructure Act (CIRCIA) requires owners and operators of critical infrastructure—including transportation systems—to report substantial cyber incidents to CISA within 72 hours and ransomware payments within 24 hours. For logistics firms, the definition of "substantial incident" includes impacts to freight tracking, logistics management systems, or OT/SCADA systems that could delay or disrupt operations. A non-compliance penalty of up to $50,000 per day applies for delay in reporting. CIRCIA requirements complement existing TSA and CISA voluntary frameworks.

The Hardest Compliance Controls for Logistics Firms

Based on our work with over 80 US logistics organizations, the following controls consistently prove the most challenging:

• Access Control (TSA Directive 2, NIST AC family): Logistics firms often have highly distributed workforces—drivers, warehouse workers, third-party freight partners—each needing different levels of access to freight management systems, inventory databases, and OT equipment. Least-privilege enforcement across thousands of endpoint and mobile users without disrupting operational speed is a persistent challenge.
• Network Segmentation (TSA Directive 1, NIST SC-7): Separating IT freight management systems from OT/SCADA systems controlling conveyors, automated sorting, and warehouse robotics requires careful network architecture and real-time monitoring. Many logistics OT systems are legacy devices with limited security capabilities.
• Supply Chain Risk Management (SCRM) (NIST SA-12, CMMC Level 2 practices): Logistics firms must assess the cybersecurity posture of their own vendors—including IT providers, cloud-based logistics platforms, and OT maintenance contractors. This creates a cascading compliance burden.
• Incident Response Testing (NIST IR-3, TSA CIRP): Tabletop exercises and full-scale simulations involving both IT and OT operations teams are required but rarely conducted at the depth needed to satisfy auditors.

US Logistics Cybersecurity Compliance Checklist

Use this checklist to assess your organization’s readiness against the primary US regulations:

• TSA Pipeline/Rail Compliance: Network segmentation between IT and OT confirmed? CIRP documented and tested within last 12 months? CISA reporting procedure established for 24-hour incident notification?
• CMMC 2.0 Level 2 / NIST 800-171: MFA enabled on all systems with CUI? CUI encrypted at rest (AES-256) and in transit (TLS 1.2+)? POA&M current with remediation dates for all deficiencies?
• CIRCIA Readiness: Incident classification criteria defined for "substantial incident"? Reporting workflow tested with CISA within 72-hour window? Ransomware payment protocols established?
• General Controls: Vendor risk assessments completed for all critical third-party logistics partners? OT asset inventory maintained with software version, patch level, and vulnerability data? Annual tabletop exercise with combined IT/OT scenario completed?

Next Steps for US Logistics Firms

For logistics decision-makers, the path forward involves several concrete actions:

1. Conduct a Regulatory Scoping Exercise: Determine which regulations apply based on your customer base (DoD, federal agencies, critical pipeline/rail operations, commercial only). Map each to your current security controls.
2. Perform a Gap Analysis: Use a framework like NIST CSF 2.0 or the TSA Performance and Accountability framework to identify control deficiencies. Prioritize TSA Directives (if applicable) and CMMC Level 2 controls (if handling defense data).
3. Deploy Continuous Monitoring for OT/IT: Logistics OT assets (conveyor controls, automated sorting, warehouse robotics) require dedicated monitoring separate from IT. CyberSilo’s Threat Exposure Management provides this separation while ensuring a unified compliance view.
4. Prepare for Incident Reporting: Establish and test incident classification, reporting workflows, and communication plans for CISA notification within 24-72 hours (depending on regulation). Ensure your legal counsel and incident response retainer are aligned.
