Unlikely to switch careers as I am an SWE already, but for my own learning, how does one learn the blue team side? Any recommended courses? I see far more penetration testing material out there.
If you don’t want to start in a junior position such as triaging, aim for things like detection engineering by learning OS internals (Windows or Linux), then also aim to learn the Win32 API. There are also lots of SOC and Blue Teams doing automation and orchestration where your existing skills could be handy.
