The video tutorial covers various network protocols, including email protocols like SMTP and IMAP, DNS functionality and security, SNMP for network management, and the implications of the SolarWinds hack. It also discusses HTTP and HTTPS for web security, and the roles of Bootp and DHCP in IP address assignment. The tutorial emphasizes the importance of security measures like DNSSEC and zero trust principles.
