who do you think have the coolest job where they defend something big and they face real blackhats? maybe the US army ?
Realize that in reality most jobs in IT are not as romantic as the hollywood movies suggest.
There are a lot of boring random tasks.
Nevertheless if where talking about high sec indeed; banks,large websites, controversial website(wikileaks etc), governments, electricity companies, transportation etc.
Anything vital that is.
Pretty sure they get attacked "often".
