Glossary / IAM Security
IAM Security
IAM (Identity and Access Management) security is the practice of confirming that identities and roles in cloud platforms can access only what they are intended to—no more, no less. Testing focuses on permissions, trust relationships, and escalation paths that could grant unintended access.
In cloud environments like AWS, Azure, and GCP, every action is authorized by IAM policies or role assignments. A solid review maps who or what can act, which resources they can reach, and under what conditions.
Effective IAM testing looks beyond obvious wildcard permissions. It checks multi-step chains (for example, a role that can create or pass another role) and cross-account trust to see whether a low-privilege identity could become high-privilege.
The outcome should be concrete: the identities or roles at risk, the shortest path that creates the access, and specific policy changes to close it. This makes results easier to validate and explain internally.
Common IAM misconfigurations that create real access paths
IAM issues rarely live in a single setting. They become meaningful when permissions, trust relationships, and automation chain together. Testing follows the same path a realistic attacker would take to confirm what is actually reachable and why.
Broad permissions and wildcard grants
Roles or users carry permissions like "*" actions or wide resource scopes that make unintended access possible once any identity is compromised.
Resolution: We compute effective permissions and map them to the minimal actions and resources required for the role.
Role chaining and pass-role misuse
Identities that can pass roles or create services can assume more powerful roles indirectly, especially in AWS, Azure, and GCP service workflows.
Resolution: We validate the shortest chain from a low-privilege identity to elevated access and restrict pass-role and service-creation permissions to specific, approved targets.
Cross-account or tenant trust without constraints
Trust policies allow external accounts or tenants to assume roles without tight conditions, expanding access beyond the intended boundary.
Resolution: We test real assume-role paths and recommend explicit principals, external IDs, and conditional constraints that enforce the trust model.
Over-privileged service principals and CI/CD identities
Automation identities often carry production-wide permissions for convenience, even when their jobs are narrow and routine.
Resolution: We trace what those identities can do in practice and propose least-privilege scopes, environment separation, and short-lived credentials.
Unbounded creation of users and roles
Users with the ability to create roles or policies can grant themselves permissions beyond their intended scope.
Resolution: We identify where permission boundaries or deny policies are missing and define constraints that prevent privilege creation beyond a fixed ceiling.
Testing approach for IAM security
IAM testing should feel controlled and reviewable. We agree on scope and access up front, validate real permission paths safely, and document exactly what was confirmed.
Confirm scope and access
We list the cloud accounts, tenants, roles, and environments in scope and agree on boundaries and timing.
Map identity and trust relationships
We review policies, role assumptions, and federation settings to understand how access is intended to work.
Validate real access paths
We test whether low-privilege identities can reach higher-privilege actions using safe, non-disruptive checks.
Document evidence and retest steps
We provide clear findings, the shortest paths observed, and simple criteria for confirming fixes.

We can review your IAM model, outline a safe scope, and explain the evidence a test would produce. If it is not the right fit, that is fine.
