Frequently Asked Questions about security-and-hardening

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I conduct a security audit on a web application?▼

To conduct a web application security audit, you map trust boundaries to identify attack vectors, validate inputs at boundaries, and review code against the OWASP Top 10 prevention patterns and a comprehensive security checklist.

What is threat modeling and how does it secure web applications?▼

Threat modeling secures web applications by mapping trust boundaries and identifying potential attack vectors. This process establishes always-do, ask-first, and never-do security practices to proactively harden systems against external threats.

How do I prevent OWASP Top 10 vulnerabilities during development?▼

Prevent OWASP Top 10 vulnerabilities by adopting security-first development practices, treating all external inputs as hostile, and applying specific prevention patterns alongside strict input validation at system boundaries.

How should I handle secrets and environment variables in a secure application?▼

Handle secrets securely by properly managing environment variables and .env files. Secure secrets management ensures sensitive data is protected across the application architecture and infrastructure.

Can I use these hardening guidelines to secure AI and LLM features?▼

Yes, these hardening guidelines cover AI and LLM security. They provide specific patterns for securing AI features like chatbots and summarizers, alongside general web application hardening and data protection practices.

What is the best way to implement rate limiting on APIs?▼

The best way to implement API rate limiting is by following dedicated security guidelines that restrict request volumes. This hardening practice protects APIs from abuse and mitigates potential attack vectors.
