First, you've gotta know how networks work. A network is basically a bunch of devices (computers, servers, phones, etc.) connected so they can share resources. Understanding network protocols (like TCP/IP, HTTP, and DNS) is key. These protocols are the rules that govern how data is transmitted across the network. For example, TCP/IP is the foundation of the internet, ensuring reliable communication between devices. HTTP is used for transferring data on the web, while DNS translates domain names (like google.com) into IP addresses (like 172.217.160.142). Knowing how these protocols function helps you identify potential vulnerabilities and how to exploit them. Another critical aspect of networks is understanding network architecture. This includes understanding how networks are structured, such as client-server models, peer-to-peer networks, and cloud-based architectures. Each architecture has its own set of security considerations. Firewalls are essential components of network security, acting as barriers between trusted and untrusted networks. Understanding how firewalls work, including their rules and configurations, is crucial for bypassing or exploiting them. Intrusion detection systems (IDS) and intrusion prevention systems (IPS) monitor network traffic for malicious activity. Knowing how these systems operate and how to evade them is an important skill for ethical hacking. Familiarizing yourself with network tools like Wireshark, Nmap, and tcpdump is also essential. These tools allow you to analyze network traffic, scan for open ports, and identify potential vulnerabilities. Also, don't forget about VPNs and proxies. Understanding how they work and how they can be used to anonymize traffic or bypass network restrictions is a valuable skill. Finally, learning about subnetting, routing, and VLANs will give you a deeper understanding of network segmentation and how to navigate complex network environments. Having a solid grasp of these networking fundamentals will set you up for more advanced hacking techniques and concepts.

Operating Systems are Key

You need to be comfortable with operating systems, especially Linux. Linux is a favorite among hackers because it's open-source, customizable, and has a ton of security tools.
