Week 9 - Your Network’s Digital Security Guard

-
Imagine a firewall as the bouncer outside your network’s club. No one gets past them except for the ones on the guest list. In cybersecurity, a firewall is a tool that monitors and filters incoming and outgoing traffic between your device and the internet. Its job? Keep the sketchy, dangerous stuff out. Firewalls protect your network from all kinds of digital threats like viruses, hackers, phishing attempts, and malware looking for a way in. You've got two options: A software firewall that lives on your device monitoring your apps/device activity and a hardware firewall that mans the gates, keeping unwanted travels from entering your domain. In short, firewalls create a secure boundary. Without them, your network’s wide open to the chaos of the internet.

Week 1 - Decoding Networks

-
  Hello everyone,     My name is Bilal, and I am pursuing a BS in Information Technology. I have an IT background from my days in the United States Air Force; however, I have always been interested in technology and how things worked under the hood. I spent a little over 9 years as a Satellite Communications Technician, working on the ground terminals used to connect to military satellites in space. It was hard work but rewarding, which led me to choose this major.      This blog will be where I share my knowledge, experiences, and maybe even a few lessons learned along the way. I'll be attempting to break down concepts and dissect the inner workings of network devices and protocols to help build a deeper understanding of the field. If you're also an aspiring network professional or someone curious about how computers communicate over the internet, I hope you enjoy following along as I attempt to decode networks.

Week 10 & Wrap Up - Vulnerable Networks and My Blogging Goodbye

-
You’d think connecting computers and devices together would be simple, but networking is full of hidden vulnerabilities that can make even seasoned pros sweat. From misconfigured firewalls to weak passwords left unchanged for years, like passwords literally being "password", the doors to trouble are everywhere. Once you're online, you're not just talking to your team, you’re basically yelling into a hallway where anyone might be listening. Phishing attacks, man-in-the-middle interceptions, outdated protocols… it’s an endless buffet of risk if you’re not careful. The good news? With strong encryption, regular updates, and a dash of paranoia, most threats can be dodged.  Well, we've finally made it to this point. The end of the course and the end of this blog journey. If you’ve been following along, first off, thank you. It means a lot that you took the time to read.  Honestly, the whole blogging-for-a-grade experience felt a bit forced. I get the intention, b...
