A CISA Directive sets out actions all US federal agencies must take to identify and secure cloud tenants in their environments
Analysis Summary
# Regulation/Compliance: CISA Binding Operational Directive 25-01 (Secure Cloud Practices)
## Overview
This directive mandates that US federal agencies and departments implement specific cybersecurity practices to identify and secure all production or operational cloud tenants within their environments, primarily in response to risks stemming from improper security control configuration in cloud services.
## Key Details
- Issuing Authority: Cybersecurity and Infrastructure Security Agency (CISA)
- Effective Date: Directive published December 17, 2024 (Specific compliance dates follow)
- Jurisdiction: US Federal Government agencies and departments
- Status: In Effect (Binding Operational Directive)
## Requirements
### Mandatory Requirements
1. **Identification and Reporting (by Feb 21, 2025):** Agencies must identify and provide CISA with the name of all in-scope cloud tenants and the owning agency/component for each.
2. **Tool Deployment and Reporting (by April 25, 2025):** Agencies must deploy all Secure Cloud Business Applications (SCuBA) assessment tools for in-scope cloud tenants and commence continuous reporting to CISA.
3. **Policy Implementation (by June 20, 2025):** Agencies must implement all mandatory SCuBA policies specified on the CISA-managed Binding Operational Directive 25-01 Required Configurations website.
4. **Ongoing Policy Updates:** Agencies must implement all future updates to mandatory SCuBA policies according to the timelines published on the Required Configurations website.
5. **New Tenant Security:** Agencies must implement all mandatory SCuBA Secure Configuration Baselines and begin continuous monitoring for new cloud tenants *prior* to granting an Authorization to Operate (ATO).
6. **Deviation Explanation:** Agencies must identify and explain any deviations found in the output of the SCuBA assessment tools when reporting to CISA.
### Recommended Practices
1. Maintenance of secure configuration baselines is critical due to dynamic vendor changes, software updates, and evolving security best practices.
## Affected Organizations
- Industries: US Federal Government agencies and departments utilizing cloud services.
- Organization Size: Not explicitly specified, but applies to all scoped government entities.
- Geographic Scope: Applies across the US Federal Executive Branch.
## Compliance Timeline
- **February 21, 2025:** Deadline to identify and report all in-scope cloud tenants and responsible agencies/components.
- **April 25, 2025:** Deadline to deploy SCuBA assessment tools and begin continuous reporting to CISA.
- **June 20, 2025:** Deadline to implement all mandatory SCuBA policies detailed on the CISA Required Configurations website.
- **Ongoing:** Implement future SCuBA policy updates per specified timelines and ensure new tenants meet baselines before receiving an ATO.
## Implementation Guidance
### Assessment Phase
- Identify all production or operational cloud tenants currently in use.
- Determine the ownership structure for reporting purposes.
- Review the CISA SCuBA Recommended Configurations website to understand the required policy set.
### Implementation Phase
- Acquire and deploy the CISA-provided SCuBA assessment tools across all identified cloud tenants.
- Remediate configurations in cloud tenants to align with every mandatory SCuBA policy requirement.
- Establish continuous monitoring processes integrated with the SCuBA tools.
### Validation Phase
- Utilize the SCuBA assessment tools to generate reports demonstrating adherence to the configuration baselines.
- Document and formally justify any identified configuration deviations for reporting to CISA.
- Ensure continuous monitoring confirms adherence before issuing new ATOs.
## Technical Requirements
The directive's technical specifics are enforced through the **SCuBA Secure Configuration Baselines**. These baselines dictate consistent and manageable security configurations for cloud services. Specific technical controls must align with these baselines, managed via the CISA-managed Required Configurations website.
## Penalties & Enforcement
- Fines: Not explicitly detailed in the summary; however, as a Binding Operational Directive, non-compliance carries significant legal and administrative consequences typical of mandatory federal directives.
- Other Consequences: CISA reports status updates on agency progress to the Secretary of Homeland Security, the Director of the OMB, and the National Cyber Director, indicating high-level oversight and accountability.
- Enforcement: Enforcement is driven by CISA's mandate to issue Binding Operational Directives and subsequent reporting to senior executive branch leadership.

- Guidance Documents: CISA SCuBA project documentation and the CISA-managed Binding Operational Directive 25-01 Required Configurations website.
- Tools: SCuBA assessment tools (to be deployed by agencies).
## Practical Recommendations
1. **Immediate Inventory:** Begin the process of discovering and cataloging all cloud tenants immediately to meet the February 21, 2025, identification deadline.
2. **Tool Readiness:** Prepare IT infrastructure to deploy the SCuBA assessment tools before the April 25 deadline to initiate continuous monitoring.
3. **Configuration Drift Management:** Establish repeatable processes now to manage and continuously enforce—not just establish—the mandated secure configuration baselines to satisfy ongoing compliance obligations.
4. **Gap Analysis:** Conduct an internal gap analysis against the published SCuBA policies to forecast remediation efforts required by June 20, 2025.
