DoD Cloud Computing Security Requirements Guide (SRG)

Why it Matters

The DoD Cloud Computing SRG establishes robust security and compliance benchmarks, ensuring government data in cloud environments is consistently protected and well-governed.

Key benefits include:

• Strengthen cybersecurity governance

Fosters strong oversight by requiring consistent security controls and management practices across cloud-hosted government data and workloads.

• Enhance regulatory alignment

Aligns organizational practices with Department of Defense and federal mandates, simplifying compliance reporting and external audit interactions.

• Increase audit readiness

Requires documented processes and evidence, enabling organizations to efficiently demonstrate compliance and maintain a state of audit preparedness.

• Promote operational resilience

Mandates comprehensive incident response and risk management, reducing service disruption and safeguarding mission-critical operations against cyber threats.

• Protect sensitive government data

Implements strict access controls and encryption measures to prevent unauthorized access and ensure confidentiality of classified or sensitive DoD information.

How it Works

The DoD Cloud Computing Security Requirements Guide (SRG) structures security practices through a tiered control framework, integrating control baselines mapped to risk levels—Impact Levels (IL2, IL4, IL5, and IL6)—that correspond to data sensitivity and mission criticality. The SRG outlines mandatory security controls, requirements, and governance activities, drawing on NIST SP 800-53 control families and federal regulatory standards, to address cloud-specific threats in aerospace and defense environments.

In practice, organizations implement the SRG by categorizing their cloud workloads, mapping them to the appropriate Impact Level, and applying the prescribed security controls such as access management, encryption, incident response, and continuous monitoring. Operational teams conduct regular risk assessments, document compliance activities, and interface with government authorizing officials to ensure governance and regulatory alignment for ongoing cloud system operation.

SmartSuite enables organizations to operationalize the DoD Cloud Computing SRG by providing a control library aligned to SRG requirements, centralizing risk registers, automating evidence collection, and supporting compliance tracking against assigned Impact Levels. Audit readiness is maintained through integrated reporting dashboards, remediation workflows, and policy governance capabilities, facilitating consistent monitoring and streamlined response to regulatory changes.

Key Elements

• Impact Level Stratification

Defines distinct information sensitivity tiers and corresponding security requirements for DoD cloud workloads.

• Baseline Security Control Families

Organizes required technical and administrative safeguards into structured categories aligned with federal standards.

• Assessment and Authorization Process

Describes procedures for evaluating, auditing, and granting provisional authorization to cloud service providers.

• Data Residency and Sovereignty

Specifies requirements for geographic location, jurisdiction, and handling of DoD data within cloud environments.

• Continuous Monitoring Protocols

Establishes ongoing oversight mechanisms to maintain compliance and assess emerging security risks.

• Incident Response Coordination

Outlines structured processes for managing security events and supporting operational resilience.

Framework Scope

The DoD Cloud Computing Security Requirements Guide (SRG) is used by cloud service providers and contractors managing Department of Defense data. The framework governs commercial and government cloud environments with DoD information, and is typically implemented for achieving provisional authorization, managing sensitive data risks, and supporting assurance programs within the DoD supply chain.

Framework Objectives

The DoD Cloud Computing Security Requirements Guide (SRG) establishes mandatory security controls and governance standards for safeguarding DoD data in cloud environments.

Protect the confidentiality and integrity of sensitive government data in the cloud

Strengthen cybersecurity risk management for DoD cloud services and providers

Enhance compliance with Defense Department regulations and cloud security requirements

Improve governance and oversight of cloud-based operations and data access

Enable ongoing audit readiness and contractor due diligence within DoD ecosystems

Support robust data protection aligned with information sensitivity impact levels

Framework in Context

The DoD Cloud Computing Security Requirements Guide (SRG) aligns DoD-specific cloud security controls with broader federal standards such as FedRAMP and NIST SP 800-171, and is often cross-referenced with CMMC; organizations use it when pursuing DoD authorization, regulatory compliance, certification, or to strengthen security governance and operational controls.

Common Framework Mappings

Organizations map DoD SRG controls to other mature frameworks to streamline authorization, demonstrate continuous compliance, and leverage established controls across cloud, federal, and industry security programs.
