How to become an information security specialist? Give advice!

I completely agree with you…. You need to study to be such a specialist. I see that such specialists are now in great demand ... Indeed, hacker attacks are often made at enterprises in order to steal valuable information. A businessman I know studied the incident response cycle (https://underdefense.com/incident-response-life-cycle-underdefense/) of hacker attacks. And he began to cooperate with one well-known company. And I want to say that these specialists have good earnings.
