When we talk about the network protocol, it is defined as the pre-set rules and conventions that are established for communications within the network and devices. The protocol includes establishing and identifying connections through devices.
Its primary features and functions are formatting specific rules for packaging, receiving, sending messages, message acknowledgement, enabling reliable network communication, and data compression.
Without a protocol, our devices will not be capable of understanding electronic signals when two devices are communicating through the network. Today, these protocols use packet switching methods to transfer messages.
The messages will be processed, divided, gathered, and assembled as it reaches its destination. Computers and devices have a variety of network protocols with specific purposes and environments.
In this article, we will look into the importance of network protocols in computers, devices, and cybersecurity.
Internet Protocols
Internet Protocols or IP is a known term for network protocols. Other well-known and high-tiered protocols such as UDP, HTTP, FTP, and TCP, are integrating with IP for more features and capabilities. Lower tiered protocols such as ARP and ICMP are also integrating with IP.
The difference between high tiered and low is that in high, the program interacts with the system closely through applications like web browsers. The low tiered interacts more with the computer hardware like network adapters. But both tiers exist in the protocol family.
Wireless Network Protocols
One of the most popular networks is the use of a wireless connection. These are connective tools like the wi-fi, LTE, Bluetooth, and others more. These networks can support mobile devices for roaming and electronic signals that do not connect the device directly through a wire.
Routing Network Protocols
A routing protocol is much more specific with its function. It focuses on the router device, source, and management. It shows the details of the network route where the information passes through.
Well-known routing protocols are EIGRP, BGP, and OSPF.
Types of Network Protocols
Here are some of the most common types of Network Protocol.
Internet Protocol (IP)
This type of protocol uses addressing and is used with TCP. It’s one of the most common protocols in connecting networks. It addresses packet communication in order to route different nodes through a network until it reaches its destination.
Transmission Control Protocol (TCP)
It’s one of the most common protocols that exist in network communication. TCP divides messages into smaller packets and sends them. As it reaches the destination, it reassembles itself.
Post Office Protocol (POP)
This type of protocol is uniquely designed to receive emails.
File Transfer Protocol (FTP)
Is a system-to-system transfer protocol. It supports multimedia, text, documents, and program files.
User Datagram Protocol (UDP)
This protocol is used most often as a substitute for TCP in the communication protocol. The protocol creates a low latency and low tolerance linking of two different applications.
Hyper-Text Transfer Protocol Secure (HTTPS)
This is a standard protocol that focuses on the security of communication in two devices. It uses a web browser and a fetching data method from a web server. It functions the same with your HTTP.
Implementing Network Protocol in Cybersecurity
Most of the latest computer operating softwares or IoT device OS already has a built-in service that is capable of default network protocols.
The integration of network protocol in cybersecurity is the use of packets and encrypted binary data systems that are used to transfer and receive data. Now that information has been a crucial element and considered to be an asset of every company, security measures within the network protocol are well established and updated frequently.
Understanding how the network protocol functions allow our experts to create a well-suited security program for a device, web application, or software.
