📦 Go REST API - Task Manager

A simple RESTful API built with Go, designed to manage tasks efficiently. This API allows you to create, read, update, and delete (CRUD) tasks with persistent storage using a JSON file.

🚀 Features

• ✅ RESTful architecture using net/http
• ✅ CRUD operations for tasks
• ✅ JSON file-based persistence
• ✅ Modular and easy to extend
• ✅ Security best practices in place

🔐 Security Implementations

This API is built with several security measures in place to protect data and ensure safe usage:

1. Input Validation and Sanitization

All incoming request data is validated and sanitized to prevent:

• SQL Injection (N/A in this project, but good habits apply)
• Cross-Site Scripting (XSS)
• Command Injection via untrusted input

2. Secure HTTP Headers

Several HTTP headers are added to protect against common web vulnerabilities:

• X-Content-Type-Options: nosniff
• X-Frame-Options: DENY
• Content-Security-Policy (to be added in future updates)
• Strict-Transport-Security (when behind HTTPS)

3. CORS Configuration

CORS policies are configured to restrict access to trusted domains:

w.Header().Set("Access-Control-Allow-Origin", "https://yourdomain.com")

4. HTTPS Enforcement

While HTTPS is not handled directly in Go, the API is expected to run behind a secure proxy (e.g., NGINX or Caddy) that enforces HTTPS on all endpoints.

5. Rate Limiting (Planned)

Rate limiting will be added to prevent abuse and denial-of-service (DoS) attacks.
