The Department of Defense (DoD) Cloud Security Playbook, Volume 1 (February 2025) redefines how cloud security should be operationalized within the U.S. defense ecosystem. It moves beyond abstract policy to offer mission-focused, implementation-ready guidance for securing cloud-based software systems. Under the shared responsibility model, Cloud Service Providers (CSPs) ensure the integrity of the underlying infrastructure, while Mission Owners (MOs) are accountable for the secure configuration, deployment, and operation of the software they manage in the cloud.
The playbook distills core cybersecurity priorities into 18 actionable “plays” designed to strengthen security across the cloud lifecycle.
Key areas of focus include:
- Infrastructure as Code (IaC): Automating secure deployment practices
- Identity, Credential, and Access Management (ICAM): Enforcing least-privilege access
- Cloud-Native Application Protection Platforms (CNAPPs): Enhancing visibility and threat protection
- Secure secrets management: Safeguarding credentials and sensitive configuration data
- Network segmentation and cyber resiliency: Limiting blast radius and sustaining operations during disruptions
Designed for software developers, program managers, acquisition leaders, and cybersecurity teams, this document serves as both a strategic roadmap and a tactical guide, enabling teams to reduce risk, accelerate Authorization to Operate (ATO), and strengthen mission assurance in hybrid and multi-cloud environments.
