Self-education in "Information Security" and in the IT field in general (for a beginner)?

Question

Books

Good afternoon! I dropped out of the university in the 3rd year, from the direction of nuclear physics. I myself subconsciously always wanted to develop in IT, but lacked confidence, while interest in hard science was slowly fading away. Now I have the opportunity and I'm starting to study in the field of information security (1 course).
I have accumulated questions : what knowledge / practical skills should be obtained first? What courses, books and programming languages ​​would be appropriate, effective and relevant to get an idea about IT in general and information security? What can you already do without training in this direction? In general, it is interesting to hear recommendations and opinions on the subject.

• Mathematics, English at a good level
  
• Progat studied in C (half a year to a year), started in Python, Pascal; tried on C++ on forums, but it was very problematic
  
• I think to start from scratch, I forgot a lot, I don’t know even more
  

Thanks in advance :)

Answer 1

And why did you decide that your interest in information security will not fade away slowly?
Honestly, I don't really understand people who announce that they want to learn something. The less you talk about what you want to learn, the less you will have obligations and excuses to others. Do you think that IB arose first, and then the knowledge that is now included in it pulled itself under it? Not talking about information security will make you an information security engineer, but your actions will fit or not fit the actions of an information security engineer. This is what I will teach, because. this fits the proud title of an information security engineer, but I won’t do this, because. it doesn't fit with the position. Gygygy.

Answer 3

It’s probably too late to recommend this, but if I were you, I wouldn’t drop from the 3rd year, but finish my studies and read and watch what you are interested in IS or SC in general. Hard science, as you put it, can give a lot in the future, it seems to me.
Becoming an information security specialist right away is a myth, as for me. in information security, it is more logical to grow from related specialties, for example, a system administrator or a network administrator, etc.
I graduated from the direction of security with a background in Computer Science, from personal experience I can say that in this order it will give the maximum profit ...
All this is a personal opinion (but also experience) and does not claim to be the ultimate truth.
