SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Hardened configurations and defense-in-depth practices to reduce blast radius, improve resilience, and streamline incident response across cloud-native apps.

Core Features & Use Cases

  • Establish security headers (CSP, HSTS, X-Frame-Options) and CORS controls.
  • Implement rate limiting on authentication endpoints and sensitive routes.
  • Provide secrets management guidance and vulnerability auditing to minimize risk.

Quick Start

Configure headers, rate limits, and secrets handling in your application following the guidance in this Skill.

Frequently Asked Questions about security-hardening

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

FAQPage Schema
How do I configure security headers like CSP and HSTS for my application?

To configure security headers, you establish Content-Security-Policy, HSTS, and X-Frame-Options directives within your application's deployment configuration. This Skill provides guidance to apply these defense-in-depth controls across network perimeters to reduce blast radius and improve resilience.

What is the best way to implement rate limiting on authentication endpoints?

The best way to implement rate limiting is by applying strict throttling controls specifically to authentication endpoints and sensitive routes. This Skill guides you through configuring defense-in-depth rate limits to protect against brute-force attacks and minimize application risk.

How does supply-chain risk assessment work for application dependencies?

Supply-chain risk assessment works by auditing your application dependencies to identify known vulnerabilities and minimize exposure. This Skill performs dependency vulnerability auditing to address real-world scenarios like compromised packages and streamline incident response.

How do I handle incident response for leaked credentials in cloud-native apps?

To handle incident response for leaked credentials, you implement strict environment-secret handling and vulnerability auditing protocols. This Skill helps streamline incident response across cloud-native apps by applying defense-in-depth practices to reduce blast radius.

Can I use defense-in-depth controls to establish CORS policies and protect sensitive routes?

Yes, you can use defense-in-depth controls to establish Cross-Origin Resource Sharing (CORS) policies and protect sensitive routes. This Skill provides explicit guidance for configuring CORS controls alongside security headers and rate limiting to secure application deployments.
