@ireteeh What I'm looking for now isn't just more coursework. It's structure, direction, and an environment that pushes me the way a real job would, working alongside people, on real problems, with real expectations.
@ireteeh Good morning Dr. Iretioluwa.
I studied Criminology and Security Studies, and somewhere in that degree, I realised security isn't just about people and institutions, but also about the systems underneath everything.
@ireteeh With every project, I document everything. Screenshots, links, what broke, how I fixed it, what I'd do differently. Sometimes the documentation takes as long as the project itself, but that's how I actually retain things.
@ireteeh Over the past year I've gone from Google IT Support basics into Cisco's Junior Cybersecurity Analyst path, and along the way I've built things beyond the coursework: an Active Directory lab from scratch, virtual machine environments, a full system rebuild after some real issues.
I also spent this week revamping my CV and trying my hand at job applications. Humbling, but necessary.
Success isn't built in a day. I'm walking towards it. Exploring internships and entry-level opportunities in cybersecurity.

Life Update
These past few weeks have been a lot. Life happened and slowed things down more than I'd like to admit.
But I'm pushing forward.
I've decided to shift toward a more hands-on approach going forward; less blindly following coursework, more practical application.
1/2
Ended with a checkpoint exam covering Modules 1 - 3.
100% on the first attempt.
Solid way to confirm everything from before the break is still locked in.

I'm back; Thank God for life & good health.
Today I wrapped up Module 2 with a lab where I installed Ubuntu Linux on a virtual machine using VirtualBox & explored the GUI.
Hands-on always hits different.
Hexadecimal (base 16) is used for IPv6 addresses & MAC addresses.
16 values: 0โ9 then aโf. Each hex digit = 4-bit digits.
IPv6 = 128 bits, split into 8 hextets of 16 bits each (4 hex digits per group).
Key insight: convert hex โ binary first, then to decimal and vice versa.
I moved on to Module 3: Number Systems.
Binary (base 2) is how computing devices communicate. IPv4 addresses are binary digits written in dotted decimal notation.
Practiced converting btw binary & decimal using positional notation. Then extended that to IPv4 address conversions.
We are hosting a quiz space this evening. Itโs an opportunity to sharpen your Cybersecurity knowledge and win prizes. Be there ๐ช

From there, cloud services: SaaS, PaaS, IaaS.
Then cloud models: Public, private, community, & hybrid clouds.
Virtualization is the foundation all of this is built on. Less hardware, faster provisioning, & better disaster recovery.

In todayโs study session, I wrapped up Module 1 and jumped into Module 2 (Cloud & Virtualization).
Starting with something that clicked hard: hierarchical network design.
Module 2: Cloud & Virtualisation
Dedicated servers had 2 problems: single point of failure, & server sprawl.
Virtualisation solves this by separating the OS from hardware via a hypervisor.
Type 1 (bare metal) installs directly on hardware. Type 2 (hosted) sits on an existing OS
MAC addresses alone donโt scale. They work at the local level but get chaotic globally.
Hierarchical design fixes this by breaking a massive flat network into organised units.
IP addresses make this work because they carry both location and identity, enabling routing.
Then I did a quick refresh on MAC vs IP addressing and a small lab using Windows GUI and CLI (ipconfig)to check network details.
Not a heavy study day, but still showed up and kept things moving.

@segoslavia@chuka_unigwe@ireteeh@jay_hunts
Had a lot going on with work, so I could only squeeze in a bit of study time.
Started Course 3 (Network Devices & Initial Configuration) and focused on the basics of reliable networks.
Covered what makes a network reliable:
โข Fault tolerance (redundancy)
โข Scalability (can grow without issues)
โข QoS (prioritizing important traffic)
โข Security (protecting systems + data)
Also touched on packet switching: data taking different paths when needed.
