Discussions like this I suppose is more discussed by people who are of higher ranks than a newbie like me but with my own little knowledge about internet security, I think learning about cyber security will go a long way in helping anyone who who wants to keep not just his personal Bitcoin data safe but to also safeguard any other internet key.
As far as the internet is concerned many people wake up every trying new measures on how to hack into people's personal security details and thereby stealing from them immediately they gain access to their security keys and that's why we all need to know the basics of Cyber security so as to stop this Intruders from accessing our respective personal Bitcoin data
It seems that although you are a newbie you are concerned about security from the start and that doesn't discourage you, but that's not how it works for most people. I have told some friends about Bitcoin in the last years, and failed in arousing their interest, not to say if I also warned them about cybersecurity threats.
I genuinely think that for small amounts you don't need special knowledge, apart from the basic every computer user should know (don't run unknown .exes, don't click on unknown links, don't send relevant information while connected to public wifis without a good VPN...).
If you want to be your own bank and store a high amount of your savings, then concerns should be higher, but not too much: as many colleagues said before, just a good hardware wallet will do for that (you can create your keys offline if you want to be ultra-safe).
And, of course, you should educate yourself and take cybersecurity courses if your aim is to escrow money from other people, especially high amounts, because you'll be targeted by hackers, but this is very unusual.
So we could say that for 80% of Bitcoiners who "play" with satoshis, there is no need of improved cybersecurity, especially if that will make them think about it twice and abandon the idea of holding any sats; for the remaining 20% it would be advisable, but it can be ignored by simply purchasing a good hardware wallet; and for the 0.0001% of escrowers, then yes, educate yourself not only in cybersecurity but also in laws and economics before managing someone else's money, just in case.
