Consider a system designed without input validation. What is the likely outcome?
AThe system may be vulnerable to attacks like SQL injection.
BUsers will have a better experience with fewer errors.
CThe system will automatically block all attacks.
DThe system will run faster and use less memory.
Step-by-Step Solution
Solution:

  1. Step 1: Understand input validation role

    Input validation checks user data to prevent harmful inputs that cause security issues.

  2. Step 2: Predict consequences of no validation

    Without validation, attackers can send malicious data, causing vulnerabilities like SQL injection.

  3. Final Answer:

    The system may be vulnerable to attacks like SQL injection. -> Option A

  4. Quick Check:

    No input validation = Vulnerable system [OK]
Quick Trick: No input checks invite attacks [OK]
Common Mistakes:
MISTAKES
  • Assuming no validation improves speed
  • Believing attacks are automatically blocked
  • Thinking user experience improves without validation
