Cross-Tenant Integration Pivot

An integration or delegated trust relationship creates access beyond the tenant, environment or organizational boundary the security team expects.

RedMaw

Definition

Integrations connect systems that were separately reasoned about. Where an integration identity holds access in more than one tenant, environment or organization, the effective trust boundary is the union of those grants rather than any single one.

How the path forms

  1. 01An integration is configured to serve more than one tenant or environment
  2. 02It is granted the privileges needed for the broadest case
  3. 03Each tenant reviews only its own side of the relationship
  4. 04A compromise of one side inherits the integration's full reach

Why it is hard to see

Each tenant's access review looks correct in isolation. The exposure exists between the reviews, in a relationship neither party owns entirely. Production-to-staging and parent-to-subsidiary relationships fail this way particularly often, because the weaker side is assumed not to matter.

Where it leads
  1. Compromised Identity
  2. Integration
  3. Connected Tenant / System
  4. Sensitive Data

Each hop validated by successful exploitation

Validation

How RedMaw validates this attack

Validation runs only inside authorized scope, with agreed exploitation limits.

  1. 01Map integration identities and the tenants they hold access in
  2. 02Establish effective privilege across each connected environment
  3. 03Determine what a compromise of the weakest side would reach
  4. 04Test only within tenants explicitly authorized for testing
