SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) and assets (resource) components.

What problem does it solve?

This Skill enhances code security by promoting best practices for input validation, authentication, data handling, and more, mitigating risks in web application development.

Core Features & Use Cases

  • Proactive Security Practices: Validates all external input, parameterizes database queries, and encodes output to prevent XSS.
  • Security Best Practices: Implements HTTPS, hashes passwords securely, sets security headers, and manages session cookies safely.
  • Dependency Security: Encourages running npm audit before releases to manage and fix security vulnerabilities.
  • Input Validation: Ensures user input is validated and parameterized queries are used to prevent SQL injection.
  • Use Case: Before deploying a new feature that accepts user input, the Skill guides through a checklist to harden the code against vulnerabilities.

Quick Start

Apply security best practices to your codebase using the security-and-hardening skill.

Frequently Asked Questions about security-and-hardening

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

FAQPage Schema
How do I prevent SQL injection and XSS in web application development?▼

To prevent SQL injection and XSS, validate all external input, parameterize database queries, and encode output. This security hardening approach ensures malicious data is neutralized before execution or rendering.

What is the best way to implement secure password storage and authentication?▼

Secure password storage and authentication require hashing passwords securely using established algorithms. This practice protects user credentials even if the underlying data store is compromised.

How do I automate security hardening for a new web feature before deployment?▼

Automate security hardening before deployment by applying a checklist that enforces HTTPS, sets security headers, manages session cookies safely, and scans dependencies for vulnerabilities.

Does running npm audit help manage security vulnerabilities in web development?▼

Running npm audit helps manage security vulnerabilities by identifying known issues in project dependencies before release. It is a proactive practice to fix risks early in the development lifecycle.

What security headers and session cookie settings are needed for hardening web applications?▼

Hardening web applications requires setting appropriate security headers and managing session cookies safely to prevent interception. Implementing HTTPS ensures encrypted data transit across all application stages.
