How does HTTPS protect against man-in-the-middle attacks during data transmission?
ABy using port 80 for communication
BBy encrypting data and verifying server identity with certificates
CBy blocking all incoming connections
DBy sending data in plain text for faster delivery
Step-by-Step Solution
Solution:
  1. Step 1: Understand man-in-the-middle attacks

    Attackers intercept data between user and server to steal or alter it.
  2. Step 2: HTTPS protection mechanisms

    HTTPS encrypts data and uses certificates to verify server identity, preventing interception.
  3. Final Answer:

    By encrypting data and verifying server identity with certificates -> Option B
  4. Quick Check:

    HTTPS = encryption + identity verification [OK]
Quick Trick: Encryption + certificates stop man-in-the-middle attacks [OK]
Common Mistakes:
MISTAKES
  • Thinking data is sent unencrypted
  • Believing blocking connections is HTTPS role
  • Confusing port 80 with HTTPS port
