Misconfiguration
A misconfiguration is an incorrect, unsuitable, or insufficiently restrictive system or application setting that causes unintended behavior, operational problems, or security exposure.
Secure APIs
A misconfiguration is a security-relevant condition in which system or application settings are incorrect, unsafe, or insufficiently restrictive.
- How it is used
- Explains how unsafe API settings expose information, operations, and credentials to attackers.
- How deep it goes
- Defines major failure modes, works through debug leakage, and recommends configuration management and smoke tests.
- Examples
- Demonstrates an invalid order_by request producing a stack trace from a debug-enabled users endpoint.
- What you can do after
- Diagnose configuration leaks with smoke tests and harden deployments by disabling debug mode and automating settings.
Infrastructure as Code, Patterns and Practices: With examples in Python and Terraform
An infrastructure or system configuration whose settings create unintended security exposure or violate required security controls.
- How it is used
- Uses infrastructure-as-code checks and reviews to prevent security exposure before systems reach production.
- How deep it goes
- Explains concrete failure modes, policy checks, module review, and breach response without detailing specific scanning implementations.
- Examples
- Uses public object storage, default database passwords, permissive firewalls, and unapproved database modules as concrete examples.
- What you can do after
- Diagnose exposure by auditing configuration and access control, then assess blast radius and remediate breaches.
