Week 12

 Week 12


Networking has evolved significantly over the past decade, with advancements in technology bringing both new challenges and solutions. Here’s how the landscape has shifted:

1. Increased Cybersecurity Threats

  • Then: Cybersecurity threats were primarily focused on malware and traditional hacking attempts targeting enterprise networks.
  • Now: The rise of ransomware, phishing attacks, and zero-day vulnerabilities has made network security more complex. Attackers now exploit IoT devices, cloud services, and remote work environments.
  • Improvements: AI-driven threat detection, Zero Trust security models, and stronger encryption protocols have enhanced network security.

2. Rise of Cloud Networking

  • Then: On-premises data centers dominated networking infrastructures. Cloud adoption was in its early stages, and hybrid environments were uncommon.
  • Now: Businesses now rely heavily on cloud services, requiring scalable and flexible networking solutions to manage hybrid and multi-cloud environments.
  • Improvements: Software-Defined Networking (SDN) and Secure Access Service Edge (SASE) have improved cloud networking efficiency, security, and scalability.

3. Expansion of Remote Work

  • Then: Remote work was less common, and Virtual Private Networks (VPNs) were the primary method for secure remote access.
  • Now: The COVID-19 pandemic accelerated remote and hybrid work models, increasing the demand for seamless, secure access to corporate networks.
  • Improvements: Zero Trust Network Access have enhanced security and performance for remote workers.

4. Growth of IoT and Edge Computing

  • Then: IoT adoption was minimal, and most network traffic was centralized. 
  • Now: Billions of IoT devices now connect to networks, generating vast amounts of decentralized data. Managing these devices presents new security and bandwidth challenges.
  • Improvements: Network segmentation, 5G connectivity, and AI-powered network management tools help improve performance and security.

5. Bandwidth and Latency Demands

  • Then: Gigabit Ethernet was considered fast, and high-speed internet access was limited in many areas.
  • Now: The demand for high-speed, low-latency connections has skyrocketed with the rise of video conferencing, cloud applications, and real-time data processing.
  • Improvements: The deployment of 5G, fiber-optic networks, and Wi-Fi 6 has significantly enhanced network speeds and reduced latency.

Networking challenges have evolved from basic security concerns and limited bandwidth to complex cloud, IoT, and cybersecurity threats. Fortunately, advancements in AI, SDN, Zero Trust security, and high-speed connectivity have helped address these challenges, making modern networks more efficient, scalable, and secure.

Week 2 Blog Post

I knew that cables and connectors existed, but I had no idea there were so many different types. Twisted pair cables are commonly used because they’re easy to handle and provide reliable speeds over short distances. Then there are fiber optic cables, which I’m familiar with since I use them for my internet and the speed is impressive. This week, the chapter also covered network architecture and the devices that enable data transmission. Ethernet is a widely used method for devices to connect and share information. Devices like hubs, switches, and routers play a crucial role in directing the data traffic. Hubs send data to all devices, while switches are more efficient, routing data only to the intended recipient. Routers connect networks such as  home networks or office networks to the internet. Understanding how these devices work together is key to effective network management and troubleshooting.
