Why Networking?
Networking is an important area of knowledge for those who want to pursue a career in cybersecurity. Here are some necessary information about networking that you should know:
TCP/IP Protocols: TCP/IP is the protocol suite that governs communication on the internet. You should have a solid understanding of its core protocols including IP, TCP, UDP, ICMP, HTTP, FTP, SSH, DNS, and SMTP.
Network Topologies: You should be familiar with different types of network topologies, such as star, bus, ring, and mesh, and how data flows through them.
Network Devices: Understand the basic functions and configuration of networking devices such as switches, routers, firewalls, and load balancers.
Network Security: Learn the principles of network security such as access control, authentication, encryption, and firewalls.
Network Addressing: You should understand IP addressing and subnetting, as well as how to configure and troubleshoot IP addresses, DHCP, and DNS.
Wireless Networking: Be familiar with the concepts of wireless networking such as 802.11 standards, WPA2, and wireless security protocols.
Network Troubleshooting: Learn how to diagnose and troubleshoot network connectivity issues using tools such as ping, tracert, and nslookup.
Network Monitoring: Understand how to monitor network traffic using tools such as Wireshark and NetFlow, and how to identify and analyze network anomalies.
Virtualization: Familiarize yourself with virtualization technologies such as VMWare, Hyper-V, and VirtualBox, and understand how to create and configure virtual networks.
Cloud Computing: Learn the basics of cloud computing, including the different types of cloud models (IaaS, PaaS, and SaaS), and the security challenges associated with cloud computing.
These are some of the basic concepts and topics that are important to know in the field of networking for cybersecurity. It's important to continue learning and staying up to date with the latest technologies and trends in the field.
