Welcome to the Web Security Guide for Python Tutorials! This guide will help you understand the basics of web security and how to implement it in your Python applications.

Common Security Threats

Here are some common security threats that you should be aware of:

  • Cross-Site Scripting (XSS): This is an injection attack where the attacker injects malicious scripts into web pages viewed by other users.
  • SQL Injection: This is an attack that allows attackers to execute arbitrary SQL commands on a database.
  • Cross-Site Request Forgery (CSRF): This is an attack that tricks the user into submitting a malicious request without their knowledge.
  • Insecure Deserialization: This is an attack where an attacker can exploit a vulnerability in the way data is deserialized.

Preventing Security Threats

To prevent these security threats, you can follow these best practices:

  • Use Secure Headers: Implement security headers like Content Security Policy (CSP) and X-Frame-Options to protect your application.
  • Validate Input: Always validate user input to prevent SQL injection and XSS attacks.
  • Use HTTPS: Encrypt your data in transit to prevent man-in-the-middle attacks.
  • Keep Dependencies Updated: Regularly update your dependencies to patch known vulnerabilities.
