Protocols

IP (Internet Protocol)

Provides logical addressing and routing of packets across networks

ICMP (Internet Conrol Message Protocol)

Error reporting and diagnostics

ARP (Address Resolution Protocol)

Maps an IP address to a MAC address on a LAN

TCP (Transmission Control Protocol)

A connection-oriented, guaranteed-delivery protocol used to send data packets between computers over a network like the Internet.

UDP (User Datagram Protocol)

A connectionless protocol that allows for the sending of data without establishing a connection, offering no guarantee of delivery

RIP (Routing Information Protocol)

A distance vector routing protocol that uses hop count as its metric

OSPF (Open Shortest Path First)

A link-state routing protocol that uses a shortest path algorithm to determine the best route for data packets within an IP network

EIGRP (Enhanced Interior Gateway Routing Protocol)

A routing protocol that uses a hybrid of distance vector and link-state technologies, allowing for efficient routing within an autonomous system

BGP (Border Gateway Protocol)

A path vector protocol used for routing between autonomous systems on the internet, enabling the exchange of routing information across different networks

DNS (Domain Name System)

A hierarchical naming system for computers, services, or other resources connected to the Internet or a private network. It translates human-friendly domain names into IP addresses

DHCP (Dynamic Host Configuration Protocol)

A network management protocol used to automate the process of assigning IP addresses and other network configuration parameters to devices on a network

NTP (Network Time Protocol)

A networking protocol used to synchronize the clocks of computers over a network, ensuring accurate timekeeping across devices

SNMP (Simple Network Management Protocol)

Application layer protocol used to collect, organise and manage information about network devices on IP networks

SSH (Secure Shell)

Secure remote logins and file transfer

HTTPS (Hypertext transfer protocol secure)

Send data securely between a web browser and a website

RDP (Remote Desktop Protocol)

Give a user remote GUI access to a Windows system

SMTP (Simple Mail Transfer Protocol)

Protocol used by email servers and clients to send and receive emails

POP3 (Post Office Protocol v3)

Allows an email client to download messages from a mail server to a local device

IMAP (Internet Message Access Protocol)

Allows email clients to retrieve messages from a mail server

FTP (File Transfer Protocol)

Standard network protocol for transferring computer files between a client and a server after establishing a connection

SFTP (SSH File Transfer Protocol)

A secure file transfer protocol

TFTP (Trivial FTP)

A lightweight protocol for transferring files, commonly used for booting devices like network routers or IP phones for loading firmware and configuring files

Syslog

A standard protocol and message format used be devices and applications to send and receive log messages, facilitating centralized logging

LDAP (Lightweight Directory Access Protocol)

Industry standard application protocol for accessing and maintaining distributed directory information services over an IP network
