BSIT400-T301 - Week 4 Blog

This week's presentation, labeled Cloud+ Module 4, provided some extensive information about how cloud networking transforms traditional infrastructure through SDN (Software-Defined Networking) and NFV (Network Functions Virtualization) technologies. The main point that caught my attention was the different methods cloud providers AWS, Azure, and GCP use to segment and route their networks. AWS VPCs maintain strict regional and availability zone boundaries, but GCP VPCs provide worldwide regional coverage, which benefits distributed applications.

The main lesson learned was the transition from hardware-based network management to logical configuration methods. Virtual operations allow users to create subnets and assign IP addresses using CIDR and manage route tables. The cloud benefits from these concepts because they enable scalability, redundancy, and security operations that do not require physical server access. The cloud stack uses OSI/TCP-IP models as its foundation, but modifies each layer to perform cloud-specific functions, which enables data movement understanding in virtual environments.

Thanks for stopping by!

BSIT380-T302 Week 2 Blog

 This week’s readings really emphasized how foundational agreements and proactive analysis are to a strong cybersecurity posture. One key takeaway for me came from the deep dive into Service Level Agreements (SLAs) . SLAs are more than just technical checklists, they are legal and operational frameworks that define accountability, especially when it comes to security. In an environment where companies outsource critical infrastructure to third-party vendors, clearly defined SLAs are what ensure providers deliver not just uptime, but compliance with security protocols like data encryption, vulnerability patching timelines, and incident response commitments. From Chapter 4, I found the section on threat intelligence particularly compelling. The idea that cybersecurity is not just reactive but also predictive stood out. Gathering, analyzing, and applying threat intelligence helps organizations stay ahead of attackers. Whether it’s understanding threat actor motives or identifying in...

BSIT380-T302 Week 1 Blog

Hello and welcome to my first entry in what I hope becomes a valuable space for sharing insights, experiences, and lessons learned in the world of cybersecurity, system hardening, and network risk management. My name is Derek Talbott, and I am currently the Site IT Manager at Michelin in Junction City, Kansas. With over a decade of hands-on experience in IT, ranging from systems administration and Active Directory management to executing cybersecurity compliance rules across global infrastructures, I’ve learned just how critical strong security practices are in maintaining operational stability. Before transitioning into the civilian IT world, I served in the U.S. Army as a 15N Avionics Mechanic, 15F Aircraft Electrician, and 25B Information Technology Specialist. Those years taught me how to stay calm under pressure, lead by example, and treat every piece of technology as mission-critical, skills that continue to guide my approach to IT security today. I’m currently wrapping up my ...

BSIT 220-T301 Week 7 Blog

 Good Evening, Welcome back to my weekly blog where we talk about what is going on in this weeks course work. One thing that stuck out to me this week was SONET and SDH. Lets dig a little deeper on some similarities and differences between the two.  SONET - Synchronous Digital Hierarchy was standardized by the ANSI (American National Standards Institute) defines a hierarchy of interfaces and frame formats for transmitting multiple digital bit steams over optical fiber.  SDH - Synchronous Digital Hierarchy was standardized by the ITU-T (International Telecommunication Union - Telecommunication Standardization Sector). It is largely compatible with SONET but has some technical differences.  SONET uses Optical Carrier (OC) levels to designate different transmission rates. The basic unit is the Synchronous Transport Signal (STS) which is like the European STM-1 (Synchronous Transport Module Level 1) in SDH. SDH uses Synchronous Transport Module (STM) levels to designate ...
