MACsec provides protection against which two types of threats? (Choose two.)

Show Suggested Answer Hide Answer
Suggested Answer: B, D

MACsec (Media Access Control Security) provides data confidentiality, integrity, and origin authenticity at Layer 2, protecting against several types of threats.

Step-by-Step Breakdown:

Man-in-the-Middle Attack Protection:

MACsec encrypts traffic at Layer 2, preventing man-in-the-middle attacks where an attacker intercepts and manipulates traffic between two communicating devices. Since the data is encrypted, any intercepted packets are unreadable.

Protection Against Playback Attacks:

MACsec also protects against playback attacks by using sequence numbers and timestamps to ensure that old, replayed packets are not accepted by the receiver.

Juniper Reference:

MACsec Configuration: Juniper devices support MACsec for securing Layer 2 communications, ensuring protection against replay and man-in-the-middle attacks in sensitive environments.

I agree with Fletcher. Those are the two main threats that MACsec helps to prevent.

Ah, the old MACsec question. I bet the exam writers are having a field day coming up with creative threats to trip us up. B and D for the win!

Wait, data decryption is a threat? Isn't that what MACsec is supposed to prevent in the first place? Hmm, better go with B and D to be safe.

Hashing attacks? That's a new one. I'm going with B and D - can't let those pesky playback and man-in-the-middle guys ruin my day.

Hashing attacks are actually not one of the threats protected by MACsec, so B and D are the correct choices.

Hashing attacks are not as common, but it's always good to be aware of all potential threats.
