Welcome to the Web Security Guide! This document provides an overview of the best practices and common vulnerabilities in web application security. Whether you are a developer, a tester, or simply interested in learning more about web security, this guide will help you understand the key concepts and recommendations.

Common Web Security Threats

Here are some of the most common web security threats:

  • SQL Injection - An attack that allows an attacker to insert or "inject" SQL code into a query string.
  • Cross-Site Scripting (XSS) - An attack that allows an attacker to inject malicious scripts into web pages viewed by other users.
  • Cross-Site Request Forgery (CSRF) - An attack that tricks the victim into submitting a malicious request.
  • Insecure Deserialization - An attack that allows an attacker to execute arbitrary code on a server.

Best Practices

To protect your web applications from these threats, follow these best practices:

  • Use Prepared Statements - When inserting data into a database, always use prepared statements to prevent SQL injection.
  • Validate Input - Always validate user input to prevent XSS and other attacks.
  • Implement CSRF Tokens - Use CSRF tokens to prevent CSRF attacks.
  • Secure Deserialization - Validate and sanitize all serialized data to prevent insecure deserialization.
