Cybersecurity Shorts: Day 15 - Essential Protocol Types Explained 🔐

Transmission Control Protocol (TCP): A reliable, connection-oriented protocol that ensures data is delivered in the correct order and without errors.

Internet Protocol (IP): A connectionless protocol that defines how data is packaged and addressed for transmission across a network.

User Datagram Protocol (UDP): A connectionless protocol that prioritizes speed over reliability, often used for applications like streaming media.

File Transfer Protocol (FTP): A protocol for transferring files between a client and a server on a computer network.

Simple Mail Transfer Protocol (SMTP): A protocol for sending email messages between servers.

Hypertext Transfer Protocol (HTTP): The foundation of data communication for the World Wide Web.

Hypertext Transfer Protocol Secure (HTTPS): An encrypted version of HTTP that provides secure communication.

Domain Name System (DNS): A hierarchical decentralized naming system for computers, services, or any resource connected to the Internet or a private network.  

Dynamic Host Configuration Protocol (DHCP): A network management protocol used on the Internet and other packet-switched networks.

Post Office Protocol 3 (POP3): A protocol used by email clients to retrieve email messages from a mail server.

Internet Message Access Protocol (IMAP): A protocol used to access email on a mail server from multiple devices.

Simple Network Management Protocol (SNMP): A protocol used to monitor and manage network devices.

Telnet: A legacy protocol used to access remote computers.

Secure Shell (SSH): A cryptographic network protocol for secure data communication, remote command-line login, and other secure network services.  

Network Time Protocol (NTP): A networking protocol for synchronizing computer system clocks over packet-switched, variable-latency data networks.

Internet Control Message Protocol (ICMP): Used for sending error messages and other diagnostic data within an IP network.

Address Resolution Protocol (ARP): Used to map an Internet Protocol address (IP address) to a physical machine address known as a Media Access Control (MAC) address.

Border Gateway Protocol (BGP): A standardized exterior gateway protocol designed to exchange routing and reachability information among autonomous systems (AS) on the Internet.  

Internet Group Management Protocol (IGMP): A communication protocol used by hosts and routers on IP networks to manage multicast group memberships.

Session Initiation Protocol (SIP): Used for initiating, modifying, and terminating sessions with one or more participants.
