SQL Injection


'SQL Injection' is a method of code injection that can cause significant damage to a database. It's a widely known technique in web hacking, involving the insertion of harmful code into SQL statements through web page inputs.

SQL injection attacks happen when attackers manipulate standard SQL queries by exploiting unprotected input vulnerabilities within a database. These attacks can enable the attacker to access, alter, and delete database information, often leading to severe consequences. SQL injections pose a significant security risk, particularly for websites utilizing SQL databases.

To guard against SQL injections, developers need to employ input validation and parameterized queries. This protection can be achieved through the use of prepared statements with SQL parameters, implementing stored procedures, and using ORM (Object-Relational Mapping) tools that help abstract SQL code. Regular security assessments and code reviews are also crucial in detecting and mitigating vulnerabilities.

Addressing the risks of SQL injection is vital for the protection and integrity of databases. It stands as a fundamental part of secure coding in web development, demanding constant attention to safeguard against emerging threats.

In summary, while SQL Injection poses a serious risk to web applications, it is preventable. Adhering to secure coding best practices and proper database interaction techniques can greatly minimize the likelihood of such attacks.
