SQL Injection

SQL injection is an attack in which malicious code is inserted into strings that are later passed to the Database Engine for parsing and execution. Any procedure that constructs SQL statements should be reviewed for injection vulnerabilities because SQL Server will execute all syntactically valid queries that it receives. All database systems have some risk of SQL Injection, and many of the vulnerabilities are introduced in the application that is querying the Database Engine. You can thwart SQL injection attacks by using stored procedures and parameterized commands, avoiding dynamic SQL, and restricting permissions on all users. For more information, see SQL Injection.
