Networking Step-by-Step 👣

In the arena of cyber security, a robust grounding in networking knowledge is essential. One needs to know how data is transferred, communicated, and secured in digital networks by means of the fundamental concepts and mechanisms.

Network Architecture
Study the different kinds of networking models such as the OSI model and TCP/IP model which determine how data is structured, transmitted, and received in a network.

OSI model
Open systems interconnection model standardizes the function of a telecommunication or computing system into seven distinct layers. The model is popularly used in understanding how different networking protocols and technologies seamlessly work together in enabling transmission or communication of data.

Network Protocols
They should also familiarize themselves with the network protocols that are required to guarantee effective communication among devices. These are just a few common examples: HTTP, HTTPS, and FTP. Through these protocols, localized data are transferred systematically from one point to the next along the layers of abstraction that construct them.

IP Addressing and Subnetting: Gain an understanding of IP addresses (both IPv4 and IPv6), how they are assigned, and how subnetting works to divide networks into smaller segments for better management and security.

Routing and Switching
Understand the roles of routers and switches with regard to a network and various related technologies and protocols such as DHCP, NAT, and other routing protocols like OSPF and BGP.

Wireless Networking
Learn about types of wireless activities, such as Wi-Fi, Bluetooth, and cellular networks. You should be aware of the security issues and best practices involving wireless communications.

Network Security
Various techniques-and tooling would have been explored to defend against:
