SQL Injection is a type of attack where an attacker inserts malicious SQL code into a database query. The goal of this attack is to gain unauthorized access to sensitive data or to modify data in the database. SQL Injection attacks are a common form of attack against web applications.

Here are some ways to prevent SQL Injection attacks:

1. Use parameterized queries: Parameterized queries are used to pass input values to a query as parameters. This helps to prevent SQL injection attacks by ensuring that the input values are properly sanitized and escaped.

2. Use prepared statements: Prepared statements are precompiled SQL statements that can be reused with different input values. They can help prevent SQL injection attacks by separating the SQL code from the input values.

3. Use input validation: Input validation is the process of checking user input for errors, such as incorrect data types or invalid characters. This can help prevent SQL injection attacks by ensuring that only valid input is used in database queries.

4. Limit access privileges: Limiting access privileges to the database can help prevent SQL injection attacks. Users should only be granted the minimum level of access necessary to perform their tasks.

5. Keep software up to date: Keeping software up to date can help prevent SQL injection attacks by patching any vulnerabilities that may exist in the software.

6. Use a web application firewall: A web application firewall can help prevent SQL injection attacks by filtering out malicious SQL code from incoming requests.
