Cross-Tenant Access Policy Review for Technology & Software
How technology & software organizations should implement EXT-05 for Microsoft 365 security and compliance.
Technology & Software organizations face unique security challenges when managing Microsoft 365 environments. The EXT-05 control (Cross-Tenant Access Policy Review) is particularly important for this sector due to soc2 and iso27001 requirements.
Why Technology & Software Organizations Need This Control
Technology & Software organizations face specific regulatory requirements including soc2, iso27001, cis. The EXT-05 control helps address these requirements by:
- Default cross-tenant access policy is not overly permissive
- Partner-specific configurations exist for known collaborators
- Inbound and outbound B2B access is explicitly controlled
Permissive cross-tenant defaults allow any external organization to collaborate with your tenant. Restricting defaults and configuring partner-specific policies ensures only approved organizations can access your resources.
Industry-Specific Considerations
When implementing EXT-05 in a technology & software environment, consider:
- **Regulatory requirements**: soc2, iso27001, cis may mandate specific configurations
- **Risk tolerance**: Technology & Software organizations typically have moderate to low risk tolerance
- **Audit frequency**: Plan for regular compliance reviews
- **Documentation**: Maintain detailed records for regulatory inspections
Implementation Steps
To implement EXT-05 in your Microsoft 365 environment:
- Default cross-tenant access policy is not overly permissive
- Partner-specific configurations exist for known collaborators
- Inbound and outbound B2B access is explicitly controlled
TrueConfig can automatically remediate this control with one click.
Technology Compliance Requirements
Technology organizations must comply with these frameworks, all of which address cross-tenant access policy review:
Why This Control Matters for Technology
Permissive cross-tenant defaults allow any external organization to collaborate with your tenant. Restricting defaults and configuring partner-specific policies ensures only approved organizations can access your resources.
Common threats in technology & software:
- • Source code theft and IP exfiltration
- • Supply chain attacks through dependencies
- • Credential compromise in CI/CD pipelines
For technology & software organizations, EXT-05 is a key component of a compliant Microsoft 365 security posture. TrueConfig helps you implement and maintain this control while meeting industry-specific requirements.
