Given this AWS setup: IAM roles restrict access, data is encrypted with KMS, and VPC security groups limit traffic. What happens if an attacker bypasses the security group?
AThe attacker is blocked by IAM roles and encrypted data remains protected.
BThe attacker can access data without any other barriers.
CThe attacker can change encryption keys easily.
DThe attacker can disable KMS encryption remotely.
Step-by-Step Solution
Solution:
  1. Step 1: Analyze the layered security setup

    Security groups limit traffic, IAM controls access, KMS encrypts data.
  2. Step 2: Consider bypassing security group

    If security group is bypassed, IAM roles still restrict access and encryption protects data.
  3. Final Answer:

    The attacker is blocked by IAM roles and encrypted data remains protected. -> Option A
  4. Quick Check:

    Multiple layers block attacker even if one fails [OK]
Quick Trick: Bypass one layer, others still protect [OK]
Common Mistakes:
  • Assuming bypassing one layer means full access
  • Thinking encryption keys can be changed easily
  • Believing KMS can be disabled remotely
