Answer 3

Read about the TCP / IP stack (OSI), about the main protocols (HTTP, TCP, UDP, SMTP, IMAP, SSH etc.), delve into the description of the most common web application vulnerabilities - OWASP TOP-10; read about the three foundations that make up information security: integrity, availability, confidentiality; read about hash functions, algorithms and encryption types; familiarize yourself with at least one of the programming languages ​​(preferably PHP, because it is common and often full of holes); read about social engineering.

Good luck with your studies.
