That makes sense too. It could be either B) portsweep or A) port scan then.

I think the answer is A) port scan because it is a general term for scanning one or more ports on a target host.

Well, a decoy port scan involves using multiple decoy IP addresses to hide the attacker's true identity, not just scanning multiple target hosts.

I would go with D) ACK scan, as it involves sending ACK packets to test for open ports.

I'm not sure, but I think C) decoy port scan could also be a possibility.

Haha, Melodie, I feel you on that one! These port scan questions can be a real headache. But I think you all are on the right track with C. The 'one-to-many' phrasing is definitely the key here. Although, if I were the exam writer, I totally would have snuck in a trick answer like 'port sweep' just to mess with you all.

Alright, let's think this through. A one-to-many scan targeting a single port? Gotta be portsweep, right? Unless... wait, is this a trick question? What if it's a decoy port scan to throw us off? Hmm, decisions, decisions.

Ugh, port scans, the bane of my existence. But yeah, I'd have to go with portsweep on this one. Seems pretty straightforward. Though I bet the exam writer is laughing maniacally, waiting to see who falls for the decoy port scan trap.

Ugh, these port scan types always trip me up. I was going to say D, 'ACK scan', but I think you guys have convinced me that C is the way to go. Although, now I'm second-guessing myself again... Someone please just tell me the answer so I can move on and worry about the next question!

I agree, the portsweep option seems the most fitting description here. It's the classic 'scan a port on many targets' kind of deal, right? Though I gotta say, the decoy port scan option is kinda intriguing. Maybe the question is trying to trick us?

You know, I was leaning towards A at first, but the more I think about it, the more I agree with Shaunna and Eleonore. A port scan is usually just a single host scanning multiple ports, whereas this sounds like a scan targeting multiple hosts on a single port. Definitely going with C, 'decoy port scan'.

Hmm, this question seems a bit tricky. A one-to-many scan targeting a single port on multiple hosts sounds like a portsweep to me. It's kinda like sweeping the port across different machines, you know?

I agree with Shaunna, I think C is the way to go here. A decoy port scan is when you use multiple source IPs to hide the real source of the scan, which sounds like what's being described in the question. Plus, I heard the exam writer likes to throw in some tricky wording to trip people up, so I'm not sure I trust the 'one-to-many' phrasing.

Hmm, I'm not convinced that B is the right answer here. Don't port sweeps usually involve scanning multiple ports on a single target host? This seems more like a single-port scan across multiple hosts, which makes me think it might be a 'decoy port scan'. What do you all think?

Therefore, decoy port scan seems like the best option in this case. Let's go with C) decoy port scan.

Agreed, a decoy port scan involves sending scan traffic to multiple hosts without actually intending to reach them all.

So, it seems like the most accurate answer would be C) decoy port scan, since it fits the description of the scenario.

That's true, but an ACK scan doesn't specifically focus on scanning a single port on multiple target hosts like a decoy port scan does.

But isn't an ACK scan also a one-to-many type of scan, where the attacker sends ACK packets to multiple target hosts?

Oof, this question looks tricky. I'm not entirely sure what a 'one-to-many' type of scan is, but it sounds like it's trying to get at the concept of a port sweep. I'm leaning towards B, 'portsweep', since that seems to fit the description best.
