Wait, can scanlogd really catch stealth scans? Not sure about that.

Nmap? Really? That's more for scanning than detection.

Scanlogd sounds familiar for detecting scans. I practiced some questions on this, and I think it’s a valid choice.

Nmap is more of a scanning tool itself, right? I don't think it detects stealth scans, but I could be wrong.

I'm not entirely sure about libnids. I feel like it’s more about network intrusion detection, but it might help with scans too?

I think portsentry is definitely one of the tools for detecting stealth scans. I remember it being mentioned in class.

Hmm, I'm a bit unsure about this one. I know the quantifiers have something to do with matching patterns, but I can't quite remember the specific symbols off the top of my head. I'll have to think this through carefully.

Hmm, I'm a bit unsure about this one. I know DDoS protection is important, but I'm not sure which of these options would be the best approach. I'll have to think it through carefully.
