Edge types

Physical/logical attachment. Semantic edges (ExecutesAs, HasPolicy) carry the security meaning.

Credential/identity authenticates to a service/endpoint (incl. SaaS/DB).

Full control (admin/owner) over a resource - implies most other capabilities on it.

Source can attach/replace the identity a compute resource runs as, including updating a workflow/orchestration service's execution identity. Also applies to data resources (caches, databases) where an identity is used for encryption or service-to-service auth. Produced both by explicit normalization (attach/assign permissions on target resources) and by derived rules (e.g., CanPassIdentity + CanModifyConfiguration on target).

Derived summary: source effectively controls target (admin OR sufficient sub-capabilities).

Source can create new resources of a type within a scope.

Destructive; persistence/impact not escalation. Excluded from default paths. Produced by explicit normalization (delete-permission IAM actions) and by derived rules (evasion/cover-tracks primitives like disabling detective services).

General modify capability (specialized by CanModifyCode/Configuration/Policy where meaningful). Produced by explicit normalization (modify permissions) and derived rules (config-modification attack paths like CloudTrail tampering, logging-service disablement).

Source can change config (env vars, layers, startup command, identity binding) to gain execution or escalate. Produced by explicit normalization (control-plane config-update permissions) and by derived rules (trigger hijacking, notification redirection).

Source can alter an identity/resource policy to grant itself/others more access. Produced both by explicit normalization (IAM/RBAC setPolicy grants) and by derived rules (deny-policy/org-policy modify capabilities that unlock gated edges).

Source can reach target over the network (post SG/firewall/route evaluation). Messaging source/target covers publicly- or privately-reachable messaging endpoints (a queue/topic/event-bus with a public resource policy is an internet-reachable target; a private messaging endpoint is a private-link source/target) - consistent with ExposedToInternet and PrivateReachability, which already admit the Messaging class.

Read configuration/metadata of a resource (recon; low base value). Produced by explicit normalization (configuration-read IAM permissions) and by derived rules (recon primitives like reading Macie findings to identify sensitive-data targets).

Delete+recreate to inherit name/identity/trust (config-drift escalation).

Source can become owner (Azure SP/app owner, resource owner) and thereby self-grant control.

Modify a resource's configuration. Produced by explicit normalization (write permissions) and derived rules (config-write attack paths).

Terminal control edge: source can administer the target boundary/resource (objective attainment).

EFFECTIVE permission (post evaluation) of an action on a target. Produced by the permission engine / effective-permission evaluator.

Placement metadata (region/subnet). Useful for filtering, not traversal.
