Which of the following is considered the most effective primary defense against SQL Injection?

a: Client-side input validation. Explanation

Explanation

b: Database-level row encryption. Explanation

Explanation

c: Parameterized Queries (Prepared Statements). Explanation

Explanation

d: Frequent database backups. Explanation

Explanation

In the experiment's 'Secure Mode', how does the database handle the payload ' OR '1'='1'?

a: It executes it as a logic bypass. Explanation

Explanation

b: It treats it as a single literal string for matching, not as part of the SQL command. Explanation

Explanation

c: It automatically deletes the user input. Explanation

Explanation

d: It crashes the application to prevent access. Explanation

Explanation

What is the key advantage of a Prepared Statement over dynamic SQL?

a: It makes the query run significantly slower. Explanation

Explanation

b: It allows the database to compile the query structure before the actual data is provided. Explanation

Explanation

c: It permits the use of more complex JOIN statements. Explanation

Explanation

d: It allows the programmer to skip writing WHERE clauses. Explanation

Explanation

Why should input validation be used if parameterized queries are already in place?

a: Because parameterized queries are easily bypassed. Explanation

Explanation

b: To provide a 'defense-in-depth' approach and reduce the overall attack surface. Explanation

Explanation

c: Input validation is the only way to prevent tautology attacks. Explanation

Explanation

d: It is not necessary at all if you use prepared statements. Explanation
