Where to dig further on information security?

Question

Information Security

Hello.
I've stopped developing and I don't know where to go.
Initially, I came to information security to learn how to develop antiviruses.
So I more or less mastered the unix system, I know the methods of protection and attacks on Wifi networks and Web applications.
Where to dig next? Well, this is not the end, I don’t feel like a super security person who knows all the penetrations and protection against them.
I also recently read the book "Social Engineering. Social Hackers".
Speaking more about web application penetrations, I mean that I know how to use various kinds of XSS, DOS and SQL on websites / sites.
Questions:
Advise books that I should definitely read in order to increase ADDITIONAL knowledge of information security, whether it's web\dextop (C++\C\Python). (Please do not advise on TCP \ IP, I have already worked with sockets and I know how they work)
What should I read to learn how to program microcontrollers, USB killers, Raspberry Pi and all sorts of other jokes?)

Answer 1

I read nonsense.
You are not safe. If you want to be safe, go to a university for a specialized specialty.
Now you are here and there grabbing some foams with absolutely no understanding of what you are doing in general.

Answer 2

What you need to read to learn how to program microcontrollers, USB killers, Raspberry Pi and all sorts of other fun?)

What for?
Do you want to work in IB or is it just a hobby? If it's just a hobby - well, read what you can find in Google.
If you work, then most of the work of a security guard is boring, boring and sometimes looks, let's say, questionable from the moral point of view of an ordinary person.
Well, unless you manage to get a job as a forensic specialist in a large office like LK.
