SQL injection

Unmoderated user data inputs could place organizational networks at risk of SQL injection attacks. Under the network attack method, external parties manipulate forms by submitting malicious codes in place of expected data values. They compromise the network and access sensitive data such as user passwords.

There are various SQL injection types, such as examining databases to retrieve details on their version and structure and subverting logic on the application layer, disrupting its logic sequences and function.

Network users can reduce the risks of SQL injection attacks by implementing parameterized queries/prepared statements, which helps verify untrusted data inputs.
