If they used a stateful inspection firewall this firewall would know if there has been a SYN-ACK before the ACK.

I agree, stateful firewalls should be a standard by now!

Wait, are we sure they're all responding like that? Seems odd.

I think it's more about the lack of IDS, honestly.

Definitely a Windows thing, they tend to be more open.

Sounds like a classic case of no stateful firewall.

I feel like this could relate to the operating system, but I can't recall if Windows or Unix is more likely to respond this way.

I think we practiced a question about stateful vs. stateless firewalls. If they're not using a stateful firewall, that might explain the ACK responses on port 80.

I remember reading that ACK scans can sometimes indicate a lack of proper firewall configurations, but I'm not sure which option that points to.

I’m leaning towards the idea that the company might not have an IDS in place, but I’m not completely confident about how that connects to the ACK scan.

I'm feeling pretty confident about this one. I just need to match up the data sources with the specific requirements outlined in the question.

I'm a little confused by the wording of this question. Are they asking about the specific purpose of each budget type, or just the general characteristics? I'll have to read through the options again to make sure I understand what they're looking for.

Consulting key stakeholders is definitely the most important consideration here. The CIO needs to get buy-in from the business leaders to make any significant changes to the IT strategy.
