Introduction: Why CSRMC?
The Department of War (DoW) — the rebranded Defense Department under the current administration — recently unveiled its new Cybersecurity Risk Management Construct (CSRMC), a major doctrinal shift in how cyber risk is conceived, managed, and operationalized within military and defense systems. (HSToday)
At its core, CSRMC is intended to replace the venerable Risk Management Framework (RMF) with a paradigm that is more dynamic, continuous, and aligned with the speed and demands of modern warfare. (Breaking Defense)

Limitations of RMF and the Need for Change
Before diving into CSRMC, it’s useful to review why the DoW leadership felt compelled to abandon (or drastically overhaul) the RMF.
Static, point-in-time assessments
The RMF process relies heavily on discrete compliance snapshots: you assess, you authorize, then you monitor. But in modern operational environments, threats evolve faster than periodic reviews can catch up. (Breaking Defense)
Excessive bureaucratic burden
Numerous documents, manual coordination, checklists, and handoffs create friction for programs and acquisitions. This can slow delivery of capabilities to the field. (Breaking Defense)
Weak linkage to mission operations
RMF often treats security in abstraction, rather than tying risk posture to warfighting objectives, mission assurance, or cyber survivability in contested battlespaces. (SecureStrux –)
Inadequate responsiveness
If a system becomes compromised or a new threat emerges between reviews, RMF offers limited built-in mechanisms for rapid corrective response.
Given these vulnerabilities and critiques, the DoW sought a more agile, responsive, and operationally integrated risk model. That model is CSRMC.
Overview of CSRMC
CSRMC is described as a lifecycle construct composed of five phases, supported by ten strategic tenets. (U.S. Department of War)
The goal is to integrate security seamlessly into development, deployment, and operation, and to shift from an audit/assessment mindset toward a continuous, resilient risk-aware posture. (U.S. Department of War)
The public release of the CSRMC document frames it as a cultural, process, and tool shift:
“This construct is intended to produce a culture, mindset and process that reimagines cyber risk management to be faster in keeping with the rate of change; more effectively assesses and conveys risk; and is less burdensome to cyber and acquisition professionals while ultimately providing operational combatant commanders with an accurate understanding of cyber risk to mission.” (U.S. Department of War)
Below, I dissect the phases and tenets and then contextualize their implications.
The Five Phases of CSRMC
Each phase corresponds roughly to system lifecycle stages, with an emphasis on embedding security and enabling continuity. The CSRMC document even maps RMF steps onto its phases:
- Design ≈ Prepare / Categorize / Select
- Build ≈ Implement
- Test ≈ Assess
- Onboard ≈ Authorize
- Operations ≈ Monitor (U.S. Department of War)
Phase 1: Design
- Identify capability needs (especially those that must operate under degraded or contested conditions)
- Select functional security and cyber survivability requirements
- Form the cross-stakeholder team (mission owner, system engineers, program manager, CSSP)
- Embed resilience and threat-informed design considerations from day zero (SecureStrux –)
The idea is to shift left in security: think of worst-case fault paths, contested communications, denial-of-service, jamming, spoofing, or supply chain compromises before coding begins.
Phase 2: Build
- Implement selected security and survivability requirements
- Feed system data into the Information System Continuous Monitoring (ISCM) alignment architecture
- Author efforts such that as components reach IOC (Initial Operating Capability), security instrumentation is present (U.S. Department of War)
In effect, build models and systems that “speak cyber” from the start and generate evidence and telemetry continuously.
Phase 3: Test
- Rigorous validation, stress testing, and mission-tailored evaluation
- Penetration testing (for systems deemed high risk)
- Automated dashboards and reports for test results
- Vulnerability remediation & assessment teams with close coordination to testing cycles (SecureStrux –)
This phase is intended to ensure that by the time systems reach operational deployment, unknowns and vulnerabilities have been surfaced and addressed.
Phase 4: Onboard
- Activate continuous monitoring at deployment
- NextGen CSSP (Cybersecurity Service Provider) validates critical controls and key artifacts
- Systems may be partially onboarded, isolated, or undergo further risk review before full integration
- Validation of risk posture toward a continuous ATO (Authority to Operate) concept (U.S. Department of War)
This is the transitional stage between development and sustained operations, and is where automation and AI tools may start doing heavy lifting.
Phase 5: Operations
- Real-time dashboards, alerts, and detection-driven oversight
- Continuous monitoring becomes active (cATO)
- High-risk systems may be disconnected by CSSP watch officers as necessary
- Routine operational risk playbooks for escalation, isolation, re-sensoring, or remediation (U.S. Department of War)
The vision is that once systems are live, cyber risk posture is constantly visible, assessed, and responsive — rather than waiting until a quarterly review.
The Ten Strategic Tenets
These ten principles underpin how CSRMC is meant to be designed, implemented, and sustained. They often cross-cut phases and enforce cultural or architectural disciplines. Here they are with commentary:
- Automation
Leverage automation to streamline evidence collection, control checks, telemetry ingestion, and compliance activity. Reduces human error and increases speed. (SecureStrux –) - Critical Controls
Focus effort and visibility on controls that have the highest impact on mission assurance, rather than trying to treat all controls equally. (SecureStrux –) - Continuous Monitoring (CONMON), Control & ATO
Replace snapshot-based ATOs with continuous posture evaluation and dynamic authorization. (U.S. Department of War) - DevSecOps
Integrate security into development pipelines, with “security as code,” CI/CD checks, and iterative validation. (U.S. Department of War) - Cyber Survivability
Ensure that systems can continue functioning (at some level) even under attack or partial degradation. This is especially important for warfighting systems. (Breaking Defense) - Training
Upskill personnel — operators, engineers, program managers — to think in operational cyber risk rather than mere compliance. (SecureStrux –) - Enterprise Services & Inheritance
Share controls, assessments, and baseline services across programs to reduce duplication. Use common services or architectures where possible. (U.S. Department of War) - Operationalization
Make cybersecurity risk visible and actionable at all levels of command, in near real time. Dashboards, analytics, risk scoring—all oriented to operations. (SecureStrux –) - Reciprocity
Allow reuse of assessments, shared artifacts, and mutual trust among systems and programs (where appropriate) to reduce redundant evaluation. (Meritalk) - Cybersecurity Assessments
Integrate threat-informed testing (red teaming, adversary emulation) aligned with operations, rather than generic checklist audits. (SecureStrux –)
These tenets are intended not as optional add-ons but as binding design constraints for the CSRMC era.
Implications & Challenges for the Defense Industrial Base
The shift to CSRMC is not just a doctrinal rebrand—it has profound practical implications, particularly for defense contractors, acquisition programs, and system integrators.
Contracting and Acquisition Change
- New programs will almost certainly require CSRMC conformity from the start
- Legacy systems may be grandfathered, but phased transitions will be mandated
- Contracts may need to embed automation, telemetry reporting, and cyber survivability requirements
Tooling and Automation Investments
- Manual processes and spreadsheets will no longer suffice
- Real-time monitoring platforms, telemetry ingestion, SIEM/XDR integration, and compliance as code tools become mandatory
- Defense firms will have to assess whether their existing GRC tools, RMF tools, or monitoring infrastructure are CSRMC-compatible
Workforce Transformation
- Engineers, system architects, cyber leads, and program managers need retraining
- Shifting mindsets from “audit compliance” to “risk-resilient operations” across development, deployment, and sustainment
Integration and Inheritance
- Programs will need to modularize control baselines, reuse assessment artifacts, and implement “inheritance” strategies
- Legacy silos or stove-piped programs may struggle to share control baselines or monitoring data
Supply Chain & Interoperability
- CSRMC doesn’t directly solve supply chain risk, but expectations will likely become stricter
- Contractors with deep subcontractor tiers must ensure telemetry, security, and survivability flows across the chain
- Integration of tool stacks across DoW, DoDIN, and defense industry partners will become essential
Accountability and Authority
- Who approves continuous ATOs or disconnection decisions? CSSP watch officers? Command-level authorities?
- The new model places operational authorities closer to cyber risk decisions, which may raise mission risk or governance debate
Certification Tension
- How will CSRMC align with existing mandates like CMMC, NIST 800-53, STIGs, or other compliance regimes?
- Some critics observe that CSRMC, so far, looks like a rearrangement of RMF under a new name rather than a fully novel model. (Breaking Defense)
Georgianna Shea, a technologist with FDD’s Center on Cyber and Technology, cautions that the phases and tenets seem to overlay rather than replace deep process gaps — particularly concerning supply chain and measurable survivability metrics. (Breaking Defense)
Still, the mandate is clear: adaptation, not resistance.
Implementation Roadmap: From Legacy to CSRMC
Below is a high-level strategic plan for organizations (within DoW, defense programs, or in the defense industrial base) to transition to and align with CSRMC:
| Stage | Objective | Key Activities | Timeline Estimate |
|---|---|---|---|
| 1. Awareness & Gap Assessment | Understand CSRMC expectations and current posture | Map existing RMF processes & toolchains; perform a gap analysis against CSRMC phases & tenets | 1–2 months |
| 2. Tool & Platform Evaluation | Select or adapt automation, telemetry, and monitoring platforms | Assess SIEM/XDR, compliance-as-code, dashboarding, telemetry pipelines, API integrations | 1–3 months |
| 3. Pilot Implementation | Pick candidate systems for initial CSRMC alignment | Use “low risk” or new-development systems to iterate CSRMC phases and automation | 2–4 months |
| 4. Training & Shift Culture | Upskill teams in CSRMC mindset | Workshops, role-based training, tabletop war games for cyber risk in operations | Running in parallel |
| 5. Full Adoption for New Systems | Mandate CSRMC for T0, new acquisitions | Enforce CSRMC contract language, design rules, development standards | Ongoing |
| 6. Legacy Transition & Backfill | Bring existing systems into CSRMC posture | Rebaseline critical controls, install telemetry, retrofit monitoring | Multi-year, phased by priority |
| 7. Feedback Loop & Evolution | Monitor performance, lessons learned, evolutionary adjustment | Adjust tenets, controls, attribution, operations playbooks | Continuous |
Key success factors include executive buy-in, funding for refactoring, and close coordination among program offices, cybersecurity leads, and warfighting stakeholders.
Risks, Critiques, and Open Questions
Although CSRMC is bold, it’s not without challenges or skeptics. Here are some of the biggest concerns and open issues:
- Mission Friction vs Security
The ability of CSSP watch officers (or system controllers) to “disconnect” a system in real time introduces a risk: disabling critical capabilities at the moment they’re needed. (Breaking Defense) - Overpromise of Automation & AI
The CSRMC vision leans heavily on AI, automation, and tooling to validate controls and detect anomalies. But those tools are still maturing, and overreliance may mask adversarial stealth or false positives. - Surface-level Reform vs Deep Change
Critics argue that CSRMC might be mostly repackaging RMF with new naming conventions, but without truly addressing structural challenges. (Breaking Defense) - Supply Chain & Vendor Risk Gaps
While CSRMC addresses system-level posture, supply chain vulnerabilities remain an Achilles’ heel. How telemetry, trust, and survivability propagate through subcontractor tiers is not yet fully specified. - Legacy Systems & Backward Compatibility
Some systems may not be feasible to retrofit for full CSRMC compliance (especially older platforms, air-gapped systems, or hardened legacy hardware). Strategies for “partial onboarding” will need careful definition. - Governance & Authority Clarity
Which entities approve or override CSSP disconnection, conditional authorizations, or partial system isolation? The doctrine must avoid confusion in high-stakes environments. - Standardization and Interoperability
Ensuring consistency across the DoW, DoDIN, other services, allied agencies, and contractor ecosystems is a massive coordination challenge. - Resource Demands
Automation, monitoring, telemetry ingestion, dashboards, and anomaly detection all demand infrastructure, skilled workforce, and budget — especially for smaller contractors or programs.
Despite these risks, the direction is clear: static, checklist-based cybersecurity will no longer suffice for the pace of warfare.
Conclusion: A New Era of Cyber Risk Posture
The announcement of the Cybersecurity Risk Management Construct (CSRMC) marks one of the most consequential shifts in defense cybersecurity policy in years. It signals an insistence that cyber risk posture be operational, continuous, and mission-integrated rather than static and compliance-bound.
CSRMC’s five phases and ten tenets lift the bar for automation, real-time monitoring, survivability, and stakeholder accountability. But its success will depend on the fidelity of execution, tool maturity, clear governance, and the willingness of every stakeholder — from acquisition offices to system engineers to warfighters — to rethink how cybersecurity is woven into the fabric of defense operations.
For those in the defense industrial base, the time to prepare is now. Whether you’re designing software, delivering systems, or overseeing mission operations, CSRMC is unlikely to be optional. Aligning early, investing in automation, and adopting a resilient mindset will be your competitive (and mission) advantage.
