Block Access from High-Risk Countries for Government & Public Sector
How government & public sector organizations should implement CA-08 for Microsoft 365 security and compliance.
For government & public sector companies using Microsoft 365, block access from high-risk countries is a security priority. This guide explains how CA-08 helps government & public sector organizations protect their identity infrastructure while meeting industry-specific compliance mandates.
Why Government & Public Sector Organizations Need This Control
Government & Public Sector organizations face specific regulatory requirements including fedramp, nist-800-53, cis. The CA-08 control helps address these requirements by:
- Conditional Access policy blocks access from high-risk countries
- Country-based named location configured with sanctioned/high-risk nations
- Level 1: North Korea, Iran, Syria
- Level 2: + Russia, Cuba
- Level 3: + China, Belarus, Venezuela
Blocking access from high-risk countries reduces geopolitical risk and helps comply with export control regulations (ITAR, EAR). While VPNs can bypass this control, it stops opportunistic attacks and reduces your attack surface from nation-state threat actors.
Industry-Specific Considerations
When implementing CA-08 in a government & public sector environment, consider:
- **Regulatory requirements**: fedramp, nist-800-53, cis may mandate specific configurations
- **Risk tolerance**: Government & Public Sector organizations typically have moderate to low risk tolerance
- **Audit frequency**: Plan for regular compliance reviews
- **Documentation**: Maintain detailed records for regulatory inspections
How to Configure
CA-08 requires the following configuration:
- Conditional Access policy blocks access from high-risk countries
- Country-based named location configured with sanctioned/high-risk nations
- Level 1: North Korea, Iran, Syria
- Level 2: + Russia, Cuba
- Level 3: + China, Belarus, Venezuela
Creates country-based named location and blocking CA policy. Emergency accounts are excluded.

Why This Control Matters for Government
Blocking access from high-risk countries reduces geopolitical risk and helps comply with export control regulations (ITAR, EAR). While VPNs can bypass this control, it stops opportunistic attacks and reduces your attack surface from nation-state threat actors.
Common threats in government & public sector:
- • Nation-state espionage campaigns
- • Ransomware targeting critical services
- • Insider threats from privileged users
For government & public sector organizations, CA-08 is a key component of a compliant Microsoft 365 security posture. TrueConfig helps you implement and maintain this control while meeting industry-specific requirements.
