Must-Know Network Protocol Dependencies
Understanding network protocol dependencies is essential for cybersecurity and networking. Here’s a quick understanding of the same:
- IPv4 and IPv6 are the foundation of all networking. ICMP and ICMPv6 handle diagnostics, while IPsec ensures secure communication.
- TCP and UDP support various protocols. SCTP and DCCP serve specific cases.
- Some TCP-based protocols are HTTP, SSH, BGP, RDP, IMAP, SMTP, POP, etc.
- UDP-based protocols are DNS, DHCP, SIP, RTP, NTP, etc.
- SSL/TLS encrypts HTTPS, IMAPS, and SMTPS.
- LDAP and LDAPs are used for directory services over TCP and secured with SSL/TLS.
- QUIC is a UDP-based replacement for TCP+TLS for faster, encrypted connections.
- MCP or Model Context Protocol is an emerging standard for communicating with LLMs.
