I find it to not be of concern. I would never have it happen, because it's a bizarre and problematic way to handle internal DNS. But anyone who can exploit private IP mapping can figure it out without DNS in the first place. So I see no reason to want to hide it.
Someone told me that his friend's kid got USD 130K job out of college as Cyber Security. Is that true?
Sure. $130K is good, but not crazy. And right now, a lot of security jobs are nonsensical. It's reasonable.
But someone dedicated might make even more, without going to school, sooner. So think of it in the broad scope.
Even in states like NY and CT I was seeing salaries around $150k for security engineer level positions. Down in FL, I was seeing mostly $110-130k, but again these are engineer level. I really only looked at the east coast during my search. Not sure about the rest of US.
What do the weekly hours look like for those kinds of salaries? I don't know anyone in that type of situation.
Normal. Standard professional days. Security positions are the same as engineering positions - just standard office hours.
Unless it's a SOC position then it becomes a 24x7 filled position. You may handle it in house or outsource for SOC.
Then there is GRC which is kind of mix between security and compliance. That is also standard working hours
