Design to prevent SQL injection.The first technique to prevent SQL injection is to make sure your application is designed to reduce the surface area through which an attacker can inject code. With good coding practices and code quality tools, you can detect user input and interfaces which expose...
An attacker wishing to execute SQL injection manipulates a standard SQL query to exploit non-validated inputvulnerabilitiesin a database. There are many ways that this attack vector can be executed, several of which will be shown here to provide you with a general idea about how SQLI works. F...
The following suggestions can help prevent an SQL injection attack from succeeding: Don’t use dynamic SQL Avoid placing user-provided input directly into SQL statements. Prefer prepared statements and parameterized queries, which are much safer. Stored procedures are also usually safer than dynamic SQ...
