SQL injection is a common vulnerability where attackers can execute malicious code which is directly executed by the database server.To detect SQL injection use both automated and manual testing and try inserting common SQL Injection payloads in the input fields.Use of prepared statements with parameterized queries are effective defense against SQL injection attacks.Cautiously involve ORM (Object-Relational Mapping) layers to interact with databases.Whitelist expected input, use regular expression for expected pattern and escape input using appropriate escaping functions.Employing web application firewalls can block malicious SQL injection attempts in real time.Ensure that database accounts should have least privileges and do not expose database errors.Conduct regular security testing to identify vulnerabilities.SQL injection remains a risk that can be mitigated by taking preventative measures.It is important to stay aware, conduct regular security testing, and apply the best practices to safeguard your system and secure sensitive data.
