What to read on the basics of information security?

Question

Information Security

Interested in this field of computer science. It’s not so much even a desire to delve into the practical part (but if someone indicates the direction of movement in the form of textbooks, I’ll be grateful), but it’s interesting to learn about the ideas of information security themselves, the principles of information protection. After all, the machine only encrypts data, hides the code among the code, using its "machine" nature, and how exactly to protect information is determined by a person.

Not so much even while hunting to delve into the practical part (but if someone indicates the direction of movement in the form of textbooks, I will be grateful)

If the textbook - then apparently not practical, but theoretical.
Precisely theoretical and you need to delve into the textbook or if you need superficial data, that is, YouTube, there are a lot of scientific priests on the topic:
