Surprised to learn it's not a chroot environment!

Wait, isn't a jail just a filter definition?

I thought it was more about monitoring services, not just blocking.

A jail is basically a netfilter rules chain for blocking IPs.

I thought a jail was the environment where fail2ban operates, but now I'm second-guessing if it's more about the rules and actions.

I feel like a jail might be more about the actions taken when a filter is matched, but I can't recall the exact details.

I remember practicing a question about fail2ban, and I think it mentioned something about monitoring services for attack patterns. Maybe that's what a jail is?

I think a 'jail' is related to how fail2ban applies rules to block IPs, but I'm not sure if it's just for one service or multiple.

Okay, I think I've got a strategy here. The earlier stages like planning and pre-design are where a lot of the key decisions are made, so that's where I'd focus my attention.

I'm pretty sure the answer is the From header, since that contains the originating location of the call.

Hmm, this is a tricky one. There are a lot of options to choose from, and I'm not entirely sure which ones would be the most appropriate for HGY. I'll need to think carefully about the key principles of the COSO framework and how they align with the company's needs.

I'm not entirely sure, but I think Benford's Law is best suited for datasets that have a natural range of values. Could it be vendor invoice amounts?
