SQL injection is a sort of security issue in which an attacker can modify an application's SQL query by inserting malicious SQL code in user$-$supplied data fields. The aforementioned kind of attack exploits the manner in which many web applications process user input without sufficient validation and sanitization.$$

To safeguard their website applications from SQL injection attacks, businesses can use a range of tactics and safety measures. These are a few key methods for protecting web applications:

Employ strong validation of input and sanitization to guarantee the safety of user$-$provided data. SQL queries should only use anticipated and sanitized input.

Install a Web Application Firewall capable of detecting and blocking SQL injection attacks through tracking incoming traffic and implementing rules to filter out dangerous requests.

Maintain the most recent security patches for your website's application framework, web server, and database management system. If vulnerabilities in newer versions are not patched, attackers may exploit them.

Encrypt any confidential information in the database. This guarantees the data is safeguarded regardless of whether an attacker acquires access to the database.

Backup your database and application data on a regular basis. Backups can help reduce the disruption of data during recovery in the event of an effective SQL injection attack.
