Cybersecurity & Cloud Security | Building in Public

[Marvel @TheCyber_Chic]

@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.

[Marvel @TheCyber_Chic]

@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.

[Marvel @TheCyber_Chic]

@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.

[Marvel @TheCyber_Chic]

@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.

[Marvel @TheCyber_Chic]

May wasn't easy. Sometimes things don't go the way you expect, and I fell off my learning journey for a bit.
But I'm back. More motivated, and ready to keep going.
No pressure, just consistent progress.

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.

@ireteeh Hello ma @ireteeh
Following along and learning a lot from your posts 👋
Would love the follow! 🙌

[Marvel @TheCyber_Chic]

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.

Day 140 of #LearningInPublic
@segoslavia @chuka_unigwe @ireteeh @jay_hunts
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.

[Marvel @TheCyber_Chic]

Hexadecimal (base 16) is used for IPv6 addresses & MAC addresses.
16 values: 0–9 then a–f. 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 → binary first, then to decimal and vice versa.

[Marvel @TheCyber_Chic]

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. It’s an opportunity to sharpen your Cybersecurity knowledge and win prizes. Be there 💪

Cybersecurity Study Update
@segoslavia @chuka_unigwe @ireteeh @jay_hunts

I had today all planned out, but my body had other ideas.

Not feeling well at all, so no study session today. I’ll pick things back up as soon as I’m up to it.

#Cybersecurity #CloudSecurity

[Marvel @TheCyber_Chic]

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.

Day 138-139 of #LearningInPublic
@segoslavia @chuka_unigwe @ireteeh @jay_hunts

In today’s study session, I wrapped up Module 1 and jumped into Module 2 (Cloud & Virtualization).
Starting with something that clicked hard: hierarchical network design.

[Marvel @TheCyber_Chic]

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

[Marvel @TheCyber_Chic]

MAC addresses alone don’t 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.

[Marvel @TheCyber_Chic]

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.

Day 136–137
@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.

[Marvel @TheCyber_Chic]

Covered what makes a network reliable:

• Fault tolerance (redundancy)
• Scalability (can grow without issues)
• QoS (prioritizing important traffic)
• Security (protecting systems + data)

Also touched on packet switching: data taking different paths when needed.
