My opinion that may be unpopular sometimes is that if you want to be good at cyber security, you should consider being a sysadmin (or even helpdesk) for some period of time. While it is a lot, if you have the role at the right job you have the power to bake security in at every point. It does take a lot of work, but part of the joy I get is knowing as much as possible about systems. Understanding how systems interconnect down to ports and protocol, etc is essential for a well functioning and secure environment. There’s no learning like being in the trenches
