The podcast delivers practical cloud security guidance for professionals who have to ship real systems on real timelines. Episodes focus on the moves that prevent costly incidents: reducing accidental exposure, tightening identity and permissions, hardening serverless triggers, securing managed platforms, and building durable defaults that survive updates and team changes. The approach is technical and operational, with clear explanations that translate directly into repeatable patterns.

Each topic is designed to help you think like both a defender and an architect: what attackers exploit first, where misconfigurations hide, and how to constrain blast radius without slowing delivery. If you want deeper reference material, a companion book expands the same concepts in a structured format, and a flash cards book supports fast review and retention for day-to-day work, interviews, and certification prep.

This episode explains why event triggers are a primary trust boundary in serverless architectures, because whoever controls the trigger often controls when and how your function executes, and the GPCS exam expects you to reason about trusted inputs and integrity. You’ll define triggers broadly—HTTP endpoints, message queues, storage events, schedules, and integration events—and then map how trigger misconfiguration can allow unauthorized invocation, replay, or substitution of “trusted” events with attacker-controlled payloads. We’ll walk through a scenario where a function is designed to run only on internal events, but a trigger configuration change or permissive access policy allows external actors to invoke it, leading to data access through the function’s permissions. You’ll learn best practices such as authenticating and authorizing invocation, restricting who can modify trigger configuration, validating event source identity, and logging both the trigger source and downstream actions so investigations can prove cause and effect. The goal is to ensure the function’s execution path remains trustworthy even as teams evolve event routing over time.

This episode focuses on least privilege for serverless workloads, because functions often start small but accumulate permissions as teams add features, and the GPCS exam regularly tests whether you can spot privilege overreach hidden behind “it’s just a function.” You’ll define function identity, permission scope, and resource boundaries, then learn how to map each function’s actions to the smallest set of allowed operations on the smallest set of resources. We’ll cover common overreach patterns such as granting broad access to storage, messaging, or key services “for convenience,” permissions that allow role assumption into stronger identities, and policies that include wildcard actions or resources that expand over time. A scenario follows a function that only needs to read from one queue and write to one database, but is given sweeping permissions that enable lateral movement and data access across environments; you’ll tighten identity scope and validate the function still performs its job while escalation paths fail. This prepares you for exam questions that ask for the best permission design and for real engineering reviews where security must not break reliability.
