SQL Injection Countermeasures Methods

Many data created very quickly every day and eventually this data is stored on databases. All processes and processors use the database management system because of the privacy of the stored data and the data must be secured in this system and do not fail in front of the potential database attacks, so it is necessary to use security models, although they differ between them. Database injection has become a common desirable attack targeting web applications, the attacker has access to the database to change SQL queries without authorization. In order to avoid losing data and making it vulnerable to the public, SQL injection must be studied and understood. In this paper, I explain SQL injection and its countermeasures.
