Welcome to the section on web security in our Python tutorials. Understanding web security is crucial for any developer working with web applications. This guide will help you grasp the basics and some advanced concepts in web security using Python.
Common Security Threats
Here are some common security threats that you should be aware of:
- Cross-Site Scripting (XSS): This is a type of attack where the attacker injects malicious scripts into web pages viewed by other users.
- SQL Injection: This attack involves inserting malicious SQL code into an input field for execution by the database.
- Cross-Site Request Forgery (CSRF): This is an attack that forces an end user to execute unwanted actions on a web application in which they are currently authenticated.
Preventing Security Threats
To prevent these threats, you can follow these best practices:
- Input Validation: Always validate user inputs to ensure they meet the expected format.
- Use Prepared Statements: When interacting with a database, use prepared statements to prevent SQL injection.
- Implement CSRF Tokens: Use CSRF tokens to prevent CSRF attacks.
