The Dangers of SQL Injection: Protect Your Website!

💥SQL injection is a common web security vulnerability that allows hackers to manipulate a website's database.

🔒By using SQL injection attacks, attackers can bypass authentication and gain unauthorized access to sensitive data.

🔍The main cause of SQL injection is improper handling of user input in website forms and queries.

⚠️SQL injection can have serious consequences, including data loss, financial damage, and reputational harm.

🔒Prepared statements are a secure way to prevent SQL injection by separating SQL code from user input.

What is SQL injection?

—SQL injection is a web security vulnerability that allows attackers to manipulate a website's database by inserting malicious SQL code through user-inputted data.

What are the consequences of SQL injection?

—SQL injection can lead to unauthorized access to sensitive data, data manipulation or deletion, financial loss, and damage to a website's reputation.

How can SQL injection be prevented?

—SQL injection can be prevented by using prepared statements or parameterized queries, which separate SQL code from user input and sanitize data to prevent malicious code execution.

Is SQL injection still a relevant security concern?

—Yes, SQL injection is still a major security concern as many websites are vulnerable to this attack due to poor coding practices and lack of security measures.

What are some best practices to protect against SQL injection?

—Some best practices to protect against SQL injection include validating and sanitizing user input, using prepared statements or parameterized queries, restricting database privileges, and regularly updating and patching software.

00:00There's a debate over how to pronounce SQL injection.

00:15SQL or sequel is a language used to communicate with databases.

00:54Websites started being connected to databases after the creation of the World Wide Web.

03:59SQL commands can be vulnerable to attacks if user input is not properly handled.

04:48Adding slashes and quotes to user input is a clunky way to prevent SQL injection.
