Security and Access Control Troubleshooting Questions

Diagnosing failures caused by authentication and authorization mechanisms and security controls. Areas covered include investigating authentication failures across local and centralized identity systems, inspecting permission and role assignments, validating access control lists and firewall rules that may block legitimate traffic, troubleshooting secure transport certificate problems and trust chains, debugging application programming interface authentication tokens and session issues, and verifying remote secure access configuration. Also includes guidance on performing security aware troubleshooting that preserves auditability and does not expose secrets, using logs and audit trails, and understanding common misconfigurations and remediation steps for identity and access related incidents.
