How is SQL injection prevented?

AAddress space layout randomization

BValidate and sanitize user input

C...in the web server as a nonprivileged user

D...cost profiling

Show Suggested Answer

Suggested Answer: B

SQL injection is a type of injection attack where malicious SQL statements are inserted into an entry field for execution.

The primary way to prevent SQL injection is by validating and sanitizing user input. This involves checking the input for malicious content and ensuring it adheres to expected patterns.

Prepared statements (parameterized queries) are also highly effective, as they treat user input as data rather than executable code.

Implementing these practices ensures that any input received from users does not manipulate SQL queries in a harmful way.

C is interesting, but I don't think it relates to SQL injection prevention.

Wait, can you really prevent SQL injection just by sanitizing input? Seems too simple.

I'm a little confused by this question. Is it asking about specific techniques to prevent SQL injection, or just general ways to secure web applications? I want to make sure I understand the scope before I start answering.

Hmm, I'm not totally sure about this one. I know SQL injection is a big security issue, but I can't remember all the different ways to prevent it. I'll have to think this through carefully.

Okay, let's see. I think the key here is to make sure you're properly validating and sanitizing any user input that gets passed to the database. That way you can avoid accidentally including malicious SQL commands. I'm pretty confident that's the right approach.
