DevSecOps in Classified Environments: Practical Approaches for Defense Programs

The Department of Defense continues to expand its adoption of DevSecOps practices as the traditional software acquisition lifecycle proves too slow for modern threat environments. For defense organizations managing classified systems and intelligence platforms, implementing DevSecOps requires navigating unique challenges that commercial best practices don’t fully address.

Why DevSecOps Matters for Defense

Traditional defense software development follows lengthy acquisition cycles where systems can take years to move from requirements to deployment. In a threat landscape that evolves daily, this timeline creates a dangerous gap between capability needs and capability delivery. DevSecOps closes this gap by integrating security into every phase of the software development lifecycle and enabling continuous delivery of tested, secured software.

The DoD’s Software Modernization Strategy emphasizes DevSecOps as a cornerstone of transformation, and programs like Platform One provide shared infrastructure for DoD-wide adoption. However, implementing DevSecOps in practice — especially in classified environments — requires solving problems that go beyond installing CI/CD pipelines.

Key Challenges in Classified Environments

Air-Gapped Networks. Many classified systems operate on networks with no internet connectivity. Standard DevSecOps toolchains that depend on cloud-hosted repositories, container registries, and package managers must be adapted to function entirely within air-gapped environments. This means maintaining local mirrors of dependencies, container images, and security vulnerability databases.

Cross-Domain Data Movement. Intelligence systems often operate across multiple classification levels, requiring carefully controlled data movement between domains. DevSecOps pipelines must account for cross-domain transfer requirements, ensuring that artifacts, configurations, and deployment packages move through approved cross-domain solutions.

Accreditation and Compliance. Defense systems require Authority to Operate (ATO) through the Risk Management Framework (RMF). DevSecOps practices must integrate compliance scanning, vulnerability assessment, and documentation generation into automated pipelines so that security posture is continuously maintained rather than assessed as a one-time gate.

Container Security. Containerized deployments on Kubernetes and similar orchestration platforms introduce new attack surfaces. Base images must be hardened, continuously scanned, and sourced from trusted registries. Runtime security monitoring must detect and respond to anomalous container behavior in production.

Practical Implementation Approaches

Organizations succeeding with DevSecOps in defense environments share several common practices:

  • Shift Security Left: Integrate static analysis, dependency scanning, and security unit tests into the developer workflow, catching vulnerabilities before code is committed
  • Automate Compliance: Generate RMF documentation and STIG compliance reports as pipeline artifacts, reducing the manual burden of accreditation
  • Infrastructure as Code: Define all infrastructure configurations in version-controlled code, ensuring environments are reproducible and auditable
  • Continuous Monitoring: Deploy runtime security monitoring to detect threats in production, complementing pre-deployment scanning with operational security awareness

Building the Right Team

DevSecOps transformation requires people with both deep technical skills and an understanding of defense operational requirements. Engineers need to understand not just Kubernetes and CI/CD pipelines, but also RMF, STIGs, NIST 800-171, and the classification handling requirements that govern defense software systems.
