- Introduction to Networking (TryHackMe Room) The Intro to Networking room on TryHackMe was the perfect starting point. This room provided a solid introduction to networking basics, focusing on topics such as IP addresses, subnets, and how devices communicate within a network. The tasks guided me through common networking tools, such as ping, traceroute, and ipconfig, which are crucial for troubleshooting and understanding network behavior.
Key Takeaways:
The fundamentals of TCP/IP networking.
How to configure IP addresses and subnet masks.
The process of routing packets and how they traverse different networks.
- Diving Deeper: Networking Concepts (TryHackMe Room) After grasping the basics, I moved on to the Networking Concepts room. This room took my knowledge to the next level, diving deeper into more complex networking concepts like VLANs, NAT (Network Address Translation), and routing protocols such as RIP and OSPF.
Key Takeaways:
An in-depth understanding of how networking is segmented with VLANs.
The importance of NAT and how it helps in conserving IP addresses.
A strong grasp on how routing protocols dynamically determine the best path for data to travel across a network.
- Understanding HTTP in Detail (TryHackMe Room) The HTTP in Detail room focused on the Hypertext Transfer Protocol (HTTP), the protocol that powers the web. Learning about HTTP methods, request-response cycles, headers, and status codes was crucial to understanding how websites interact with users. This room also explained the underlying concepts of HTTPS, cookies, and sessions, giving me a comprehensive understanding of web-based communication.
Key Takeaways:
The different types of HTTP requests (GET, POST, PUT, DELETE, etc.).
How web servers process requests and respond with appropriate status codes (200, 404, etc.).
The role of cookies and how they maintain stateful sessions between clients and servers.
- Deep Dive into DNS (TryHackMe Room) DNS (Domain Name System) is the backbone of the internet, converting human-readable domain names into IP addresses. In the DNS in Detail room, I learned how DNS works, how to query DNS servers, and how attacks like DNS spoofing and cache poisoning can compromise systems. Understanding DNS is critical for penetration testers, as it plays a major role in many cyberattacks.
Key Takeaways:
How DNS resolves domain names to IP addresses.
The concept of authoritative DNS servers and how they are used in domain resolution.
How DNS security mechanisms, like DNSSEC, help prevent attacks.
- How Websites Work (TryHackMe Room) The How Websites Work room was a great follow-up, providing insights into the architecture and components of modern websites. From web servers to databases, front-end interactions to server-side processes, this room gave me a deeper appreciation of the technical side of websites.
Key Takeaways:
The relationship between web servers, databases, and the application layer.
The role of HTML, CSS, JavaScript in delivering dynamic web pages.
How web hosting works and the importance of understanding web application security.
- Hack The Box Academy: Network Foundations In addition to TryHackMe, I also completed the Network Foundations module from Hack The Box Academy. This module was particularly helpful in providing hands-on experience with networking concepts. From packet analysis to working with network tools like Wireshark and Nmap, this module bridged the gap between theoretical knowledge and real-world application.
Key Takeaways:
Hands-on experience with common network protocols like ARP, ICMP, and TCP.
Understanding packet structures and how to analyze network traffic using tools like Wireshark.
The role of firewalls, routers, and switches in network security and monitoring.
Conclusion: Where Do I Go from Here?
Completing these rooms and modules was a fantastic learning experience. Each resource provided a different piece of the networking puzzle, and together, they’ve given me a comprehensive understanding of how networks operate, how data is transferred, and how security vulnerabilities can be exploited. This knowledge will certainly help me as I continue my journey in cybersecurity.
Moving forward, I plan to deepen my understanding of advanced networking concepts, like VPNs, IDS/IPS systems, and network automation. I’m also excited to explore how these skills translate into penetration testing and ethical hacking.
I highly recommend these resources to anyone looking to strengthen their networking skills. Whether you’re new to the field or an experienced professional, there’s always something new to learn.
