DISA STIG Hardened CentOS Stream 9 for Government & Defense Workloads

STIG-Aligned Security Hardening

The operating system is configured using DISA STIG-aligned security controls designed to reduce system attack surface and enforce strong security posture from the moment the virtual machine is deployed. With focus on FedRAMP authorization, particularly for DoD cloud services which require a minimum of FedRAMP Moderate.

• Hardened authentication, password, and account management policies aligned with DISA STIG security guidance.
• Secure SSH configuration and network service restrictions to minimize exposure of critical services.
• File system protections, permission enforcement, and auditing configurations designed to support traceability and system integrity.
• System logging and auditing controls to support monitoring and incident response activities.
• Reduced attack surface through least-privilege configurations and hardened system defaults.

Designed to Support Faster ATO and Security Reviews

Security authorization processes often require extensive documentation, validation, and configuration evidence. By providing a pre-hardened baseline along with security assessment artifacts, this image helps reduce the effort required to prepare systems for security review and authorization activities.

• Reduces manual operating system hardening required during ATO preparation.
• Provides security evidence that can assist with control validation and security documentation efforts.
• Supports automation-friendly outputs that integrate with compliance scanning and continuous monitoring tools.
• Enables repeatable, standardized system deployments across regulated environments.
• Improves transparency for security reviewers by making system security posture visible immediately after deployment.

Aligned with Modern DevSecOps and Continuous ATO Practices

Modern authorization approaches increasingly emphasize continuous monitoring and automated security validation. The Sedetos hardened image supports these practices by providing machine-readable compliance outputs and a consistent hardened baseline that can integrate into DevSecOps pipelines and continuous authorization workflows.
