SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Insecure-defaults detects fail-open insecure defaults such as hardcoded secrets, weak authentication, and permissive security settings, which can cause production systems to run insecurely.

Core Features & Use Cases

  • Detects hardcoded credentials and weak defaults in config management, deployment templates, and environment handling.
  • Scans for patterns that yield insecure behavior when env vars are missing or defaults are used, enabling proactive remediation.
  • Use cases include security audits, IaC reviews, and configuration governance across applications.

Quick Start

Analyze a project's configuration and environment handling to surface insecure defaults and generate actionable remediation guidance.

FAQPage Schema
How do I scan for hardcoded secrets and insecure defaults in my codebase?

Security audits for insecure defaults detect fail-open configurations by analyzing code patterns that mishandle environment variables. They uncover hardcoded credentials and weak settings that cause production systems to run insecurely when defaults are used.

Can I use this for IaC validation and configuration reviews?

Insecure defaults detection is suitable for security audits, configuration governance, and IaC reviews across applications. It analyzes configuration management and deployment templates to identify hardcoded credentials and permissive security settings.

How do I detect fail-open behavior when environment variables are missing?

You can detect fail-open behavior by scanning for code patterns that mishandle configuration and environment variables. This identifies when applications yield insecure behavior due to missing environment variables or reliance on weak default settings.

What kind of output can I expect from an insecure defaults security audit?

The output is a structured report containing actionable mitigations for detected insecure defaults. It highlights hardcoded credentials, weak authentication, and permissive permissions discovered during the code and configuration pattern analysis.

Are there limitations to detecting insecure defaults in production environments?

The primary limitation is that it relies on analyzing code patterns and static configuration management. It may not detect complex runtime security vulnerabilities or dynamic secrets injected into production environments outside the codebase.
