Cross-Tenant Access Policy Review for Retail & E-Commerce
How retail & e-commerce organizations should implement EXT-05 for Microsoft 365 security and compliance.
For retail & e-commerce companies using Microsoft 365, cross-tenant access policy review is a security priority. This guide explains how EXT-05 helps retail & e-commerce organizations protect their identity infrastructure while meeting industry-specific compliance mandates.
Why Retail & E-Commerce Organizations Need This Control
Retail & E-Commerce organizations face specific regulatory requirements including pci-dss, soc2, 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 retail & e-commerce environment, consider:
- **Regulatory requirements**: pci-dss, soc2, cis may mandate specific configurations
- **Risk tolerance**: Retail & E-Commerce 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
EXT-05 requires the following configuration:
- Default cross-tenant access policy is not overly permissive
- Partner-specific configurations exist for known collaborators
- Inbound and outbound B2B access is explicitly controlled
