Which practice minimizes SQL injection risk in address CRUD operations?

• A. Parameterized queries or prepared statements
• B. Only use static SQL strings
• C. Disable input validation to speed processing
• D. Use high-privilege accounts for faster access

Answer: (A)

Parameterized queries or prepared statements minimize SQL injection risk by separating the SQL code from the data you supply. When you use placeholders in your query and bind actual address values (like street, city, zip) as parameters, the database treats those inputs strictly as data, not as part of the SQL command. This means any stray characters or SQL syntax in the input won’t change the structure of the query, so an attacker can’t inject additional commands. That approach is especially important in create, read, update, and delete operations for addresses, where user-supplied fields are incorporated into queries. For example, binding a user-provided city name as a parameter ensures it’s stored and compared as data, not executed as SQL. Static SQL strings without parameter binding are risky because they often involve concatenating user input into the query, which can be crafted to alter the query’s logic. Disabling input validation is dangerous because it removes a line of defense and can let harmful input slip through. Using high-privilege accounts doesn’t prevent injection and can magnify damage if an injection does occur; it’s better to follow least-privilege principles and use parameterized queries in combination with proper access controls. So, the best practice is to use parameterized queries or prepared statements.
