- **April 25, 2025:** Deadline for deploying all SCuBA assessment tools for in-scope tenants.
- **June 20, 2025:** Deadline for implementing all mandatory SCuBA policies.
- **Prior to ATO:** Mandatory implementation of baselines and initiation of continuous monitoring for all new cloud tenants.
## Implementation Guidance
### Assessment Phase
- Inventory and document all existing cloud tenants, noting ownership and system components.
- Deploy CISA-developed automated configuration assessment tools to baseline current configurations against SCuBA requirements for in-scope services.
### Implementation Phase
- Remediate identified misconfigurations and implement the mandatory SCuBA policies by the specified June 20, 2025 deadline.
- Integrate assessment data feeds into CISA's central monitoring infrastructure.
### Validation Phase
- Ensure continuous monitoring is established for all cloud tenants (new and existing).
- Verify that new tenants do not receive an ATO until they meet all mandatory SCuBA Secure Configuration Baselines.
## Technical Requirements
The SCuBA baselines are initially focused on securing **Microsoft 365** environments, specifically:
* Azure Active Directory / Entra ID
* Microsoft Defender
* Exchange Online
* Power Platform
* SharePoint Online
* OneDrive
* Microsoft Teams
CISA may expand the SCuBA scope to cover other cloud products in the future.
## Penalties & Enforcement
- Fines: Specific monetary fines are not detailed in this summary, but violations of a CISA Binding Operational Directive are taken seriously by the federal government.
- Other Consequences: Non-compliance risks unauthorized access, data exfiltration, service disruption, and potential adverse findings during federal auditing processes.
- Enforcement: Enforced through CISA's continuous monitoring infrastructure and required reporting mechanisms directed at federal agencies.
## Related Standards
- SCuBA Secure Configuration Baselines: CISA-developed standards referenced by the BOD for configuration guidance.
## Resources
- Official Documentation: CISA BOD 25-01 documentation (Link references available in the original article).
- Guidance Documents: CISA Secure Cloud Business Applications (SCuBA) guidance documents provide the specific configuration requirements.
## Practical Recommendations
1. **Prioritize Inventory:** Immediately begin creating a comprehensive, verified inventory of all cloud tenants as the first critical deadline is imminent (February 2025).
2. **Tool Adoption:** Acquire and deploy the recommended CISA assessment tools without delay to gauge compliance gaps for Microsoft 365 services.
3. **Configuration Hardening:** Treat the implementation of mandatory SCuBA policies as a top priority to meet the June 2025 deadline, focusing specifically on the identified M365 components.
4. **Process Shift:** Integrate SCuBA baseline checks into the official ATO process for all future cloud service deployments, ensuring pre-ATO compliance.

# Regulation/Compliance: CISA Mobile Communications Best Practices (Mobile Security Guidance)
## Overview
Following cyber espionage targeting U.S. telecommunications companies (attributed to actors like Salt Typhoon), CISA released guidance advising senior government and political individuals on best practices to secure sensitive mobile communications against interception or manipulation.
## Key Details
- Issuing Authority: Cybersecurity and Infrastructure Security Agency (CISA)
- Effective Date: Immediately (Guidance document release).
- Jurisdiction: Individuals in senior government or political positions utilizing mobile devices for sensitive communications within the U.S. context.
- Status: Guidance (Recommended practices).
## Requirements
### Mandatory Requirements
None explicitly stated as mandatory for all users, but certain controls are strongly necessary for targeted senior individuals:
1. Use only End-to-End Encrypted (E2EE) messaging applications (e.g., Signal).
2. Replace SMS as a second factor with Phishing-Resistant Multi-Factor Authentication (MFA).
3. Stop using personal VPNs due to "questionable security and privacy policies."
### Recommended Practices
1. Use a dedicated password manager for all credentials.
2. Set a PIN for mobile phone accounts to prevent SIM-swapping attacks.
3. Regularly update all software.
4. Switch to devices with the latest hardware security features.
5. **For iPhone Users:** Enable Lockdown Mode, disable iMessage for SMS fallback, secure DNS queries, activate iCloud Private Relay, and restrict app permissions.
6. **For Android Users:** Prioritize devices from manufacturers with strong security commitments, use RCS only if E2EE is active, configure DNS to a trusted resolver, enable Enhanced Protection for Safe Browsing in Chrome, and ensure Google Play Protect is enabled.
## Affected Organizations
- Industries: Government, Political Organizations, and related staff.
- Organization Size: Not size-dependent, but focused on *individuals* holding senior government or political positions who are potentially targeted by sophisticated state actors.
- Geographic Scope: U.S. entities and personnel operating internationally if dealing with sensitive data.
