IAM Permission Boundaries are an advanced AWS security feature used to set the maximum permissions an identity-based policy can grant to an IAM entity (user or role). This allows security teams to safely delegate role creation to developers while strictly enforcing least-privilege principles, preventing unintended privilege escalation.

This guide provides a deep dive into hardening AWS Identity and Access Management (IAM) configurations. It teaches advanced security practices, including enforcing the principle of least privilege, defining granular policy scopes, implementing permission boundaries, and leveraging Access Analyzer to ensure continuous compliance and minimize the blast radius of security breaches.

A comprehensive guide to implementing least-privilege security for AWS Lambda execution roles. It details the process of auditing existing permissions, analyzing actual API usage via CloudTrail and IAM Access Analyzer, creating narrowly scoped IAM policies, and enforcing strict permission boundaries (SCPs) to eliminate over-privileging and minimize the blast radius.

This skill governs the secure ingestion and indexing of enterprise documents from diverse connectors (e.g., Google Drive, Confluence, Jira). Key functions include mandatory PII filtering (stripping emails, phones, SSNs) before indexing, preserving strict permission boundaries, and enforcing data retention policies to ensure compliance with global regulations like GDPR and CCPA.

This guide provides a comprehensive approach to securing AWS Identity and Access Management (IAM) configurations. It walks practitioners through inventorying existing permissions, using Access Analyzer to identify overly permissive policies, implementing specific resource scoping, and attaching permission boundaries. Key strategies include enforcing least privilege access, managing credential rotation, and meeting stringent compliance requirements like SOC 2 and PCI-DSS.
