Identity propagation review traces how identity proof, credential handling, and authorization decisions flow across users, services, and sessions to detect trust boundary failures. It requires evidence-backed analysis of code, configuration, and tests to find impersonation risks.

Account takeover prevention checks assess weak challenge flows, unsafe fallback paths, and client-controlled claims in recovery and session-adjacent flows. The review confirms rate limiting, step-up enforcement, and logging are present to block privilege escalation.

Trust boundary analysis for service-to-service flows traces identity context and privilege decisions across components. It identifies broken trust propagation and client-controlled headers that could allow an attacker to gain unintended privileges across services.

An OWASP security review can find step-up authentication bypasses by analyzing evidence of credential handling, authorization, and step-up enforcement across code and operational controls. It flags unsafe fallback paths where attackers might impersonate users.

Detecting broken trust propagation requires tracing identity proof and authorization decisions across trust boundaries in code, configuration, and documentation. An evidence-backed review prioritizes attack paths like account takeover and client-controlled claims.

Reviewing identity propagation without runtime evidence limits analysis to code, configuration, tests, and documentation. The review cannot dynamically verify rate limiting or step-up enforcement, relying on static proof of credential handling and authorization controls.
