Fundamental IT Skills

The Knowledge Behind Every Cybersecurity Professional

When I started learning cybersecurity, I was naturally drawn to the more visible parts of the field: penetration testing, ethical hacking, vulnerability assessment, network security, and understanding how attackers compromise systems.

These topics are interesting, but the more I explore cybersecurity, the more I realise that there is something underneath all of them that deserves just as much attention: fundamental IT skills.

You cannot properly investigate a suspicious network connection if you do not understand how networks communicate. You cannot investigate unusual system behaviour if you have no idea how an operating system manages processes, users, permissions, and resources. And you cannot confidently work with security tools if you do not understand what those tools are actually doing.

Cybersecurity does not exist separately from IT. It operates on top of it.

Here are some of the fundamental IT skills I believe anyone learning cybersecurity should take seriously.

Understanding Operating Systems Beyond the Desktop

Most people interact with operating systems through graphical interfaces. We open applications, create folders, install software, and change settings. That is enough for everyday computer usage, but it is not enough when you start investigating how systems work.

An operating system manages processes, memory, storage, users, permissions, and communication between hardware and software.

As someone learning cybersecurity, I am particularly interested in understanding Linux and Windows from an administrative and security perspective.

For Linux, this means becoming comfortable with commands such as:

"ls" – Listing files and directories.
"cd" – Navigating between directories.
"pwd" – Identifying the current working directory.
"chmod" – Changing file permissions.
"ps" – Viewing running processes.
"grep" – Searching through text.
"sudo" – Executing commands with elevated privileges.
"ss" – Inspecting network sockets.

These are not just commands to memorise. They provide a way to inspect and understand what is happening inside a system.

For example, knowing how Linux file permissions work helps explain why certain users can access sensitive files while others cannot. Understanding running processes helps when investigating suspicious activity.

I also want to understand Windows beyond its graphical interface, particularly PowerShell, Event Viewer, user accounts, services, and NTFS permissions.

The goal is not to become dependent on commands. It is to understand the system well enough to know which commands are useful and why.

Networking: Understanding How Systems Communicate

Networking is one of the areas I consider essential for anyone pursuing cybersecurity.

Every time a device accesses a website, communicates with a server, or connects to another machine, networking protocols make that communication possible.

Without understanding networking, many cybersecurity concepts become difficult to follow.

Some of the concepts worth learning include:

IP addressing: How devices are identified on a network.
DNS: How domain names are translated into IP addresses.
DHCP: How devices obtain network configuration automatically.
TCP and UDP: Two transport protocols with different communication characteristics.
HTTP and HTTPS: How web applications communicate with clients.
Ports: How services are identified and accessed on a machine.
Subnetting: How IP networks are divided into smaller networks.
Firewalls: How network traffic is filtered according to defined rules.

Consider a practical example.

Suppose you are investigating a server that appears to be communicating with an unfamiliar external IP address.

Before jumping to conclusions, you need to understand what an IP address represents, which protocol is being used, which port is involved, and whether the connection is expected.

Tools such as Wireshark, "ping", "traceroute", "nslookup", and "nmap" become much more useful when you understand the networking principles behind them.

I am learning to treat networking as something to investigate, not just a collection of definitions to memorise.

Command-Line Proficiency

The command line deserves its own place because it changes how you interact with computers.

Graphical interfaces are useful, but they can hide details that become important when troubleshooting, automating tasks, or investigating security incidents.

Linux terminals and Windows PowerShell allow you to interact directly with system functionality.

For cybersecurity, command-line proficiency becomes useful in several situations:

Inspecting system configurations.
Searching logs for unusual activity.
Managing users and permissions.
Testing network connectivity.
Identifying running services.
Automating repetitive tasks.
Working with security tools.

For example, imagine having thousands of log entries and needing to find failed login attempts.

Searching manually through every entry would be inefficient. Learning commands such as "grep", "awk", and "sort" can help narrow down the information.

The important distinction is understanding what a command does before executing it, particularly when working with elevated privileges or commands that modify system configurations.

File Systems, Permissions, and Access Control

One of the most important security concepts is controlling who can access what.

This sounds simple, but access control is deeply connected to how operating systems manage files, directories, users, groups, and permissions.

In Linux, permissions are commonly represented through read, write, and execute privileges.

For example:

ls -l

Might produce an entry such as:

-rwxr-xr-- 1 user developers 2048 example.sh

Understanding this output helps you identify who owns a file, which group it belongs to, and what different users are allowed to do.

This becomes particularly important when learning about:

The principle of least privilege.
Privilege escalation.
File permission misconfigurations.
Sensitive data exposure.
User and group management.

A file that is readable by everyone when it contains sensitive information is not merely an administrative oversight. It can become a security problem.

Learning permissions at the operating-system level makes security concepts much easier to understand in practice.

Basic Scripting and Automation

You do not necessarily need to become a software developer to work in cybersecurity, but knowing how to write scripts is a significant advantage.

Scripting helps reduce repetitive work and makes it possible to investigate information more efficiently.

Python and Bash are particularly useful starting points.

Python can help with:

Processing log files.
Working with APIs.
Analysing structured data.
Automating repetitive tasks.
Performing basic network-related operations.

Bash is useful for interacting with Linux systems, combining commands, and automating administrative tasks.

For example, a simple Python script can count how many times a particular IP address appears in a log file.

That might sound like a small exercise, but it introduces useful skills: reading files, processing strings, using loops, and extracting information.

These are the same programming fundamentals that become useful when working with larger security datasets.

Understanding Virtualisation and How to Build a Lab

Reading about cybersecurity concepts is useful, but eventually you need an environment where you can experiment.

This is where virtualisation becomes important.

Tools such as VirtualBox and VMware allow you to run virtual machines without needing separate physical computers.

You can create a small lab containing:

A Linux virtual machine.
A Windows virtual machine.
A deliberately vulnerable application.
A virtual network connecting the machines.

This gives you an environment to practise system administration, networking, vulnerability assessment, and security monitoring.

For example, you could configure a Linux server, inspect its open ports, review its running services, and investigate its logs.

You could then introduce a configuration weakness in that isolated environment and observe how it affects the system.

The important thing is to practise in systems you own or have explicit permission to test.

A personal lab also makes mistakes less expensive. You can experiment, break configurations, restore snapshots, and repeat exercises without putting your everyday computer at risk.

Troubleshooting and Reading Logs

Troubleshooting is an underrated IT skill, especially when learning cybersecurity.

Not every unusual system event is an attack. Not every failed connection indicates malicious activity. Sometimes the problem is a misconfigured service, incorrect permissions, DNS resolution, or an application that has stopped responding.

The ability to investigate before making assumptions is valuable.

A good troubleshooting process involves:

Identifying the actual problem.
Gathering relevant information.
Checking logs and system configurations.
Testing possible explanations.
Making one change at a time.
Verifying whether the issue has been resolved.

Logs are particularly important because they provide a record of events that occurred within a system or application.

Learning where to find them and how to interpret them is a useful starting point for understanding security monitoring and incident response.

On Linux, you can begin exploring system logs through:

journalctl

On Windows, Event Viewer provides access to application, security, and system events.

Over time, you begin to understand that troubleshooting and security investigation share an important skill: following evidence instead of guessing.

Putting These Skills Into Practice

One thing I am trying to avoid while learning cybersecurity is collecting tools without understanding the technology behind them.

It is easy to install Kali Linux, open Nmap, run a scan, and admire the results. But the more valuable exercise is understanding what the scan actually discovered.

Why is a particular port open? What service is listening? Is that service supposed to be exposed? What does the service do? What would happen if it were misconfigured?

Those questions turn tool usage into actual learning.

A practical learning sequence could look something like this:

Area| Practical exercise
Linux| Create users, manage permissions, and inspect processes.
Networking| Configure IP addresses and investigate DNS resolution.
Command line| Search logs and automate simple tasks.
File systems| Experiment with file ownership and permissions.
Python| Write a script to analyse a sample log file.
Virtualisation| Build an isolated Linux and Windows lab.
Troubleshooting| Investigate and resolve a deliberately introduced configuration problem.

You do not need to master everything before moving into cybersecurity. However, revisiting these fundamentals while learning more advanced topics makes a noticeable difference.

Final Thoughts

I am beginning to see fundamental IT knowledge differently as I continue learning cybersecurity.

It is not simply a list of prerequisites to complete before getting into the interesting stuff. It is the knowledge that allows you to understand what security tools are measuring, what vulnerabilities actually affect, and why certain configurations create risks.

An individual can learn to run a vulnerability scanner without understanding the underlying network. They can execute Linux commands without knowing how permissions work. They can follow a penetration-testing tutorial without understanding why a particular vulnerability exists.

But there is a difference between following instructions and understanding the technology you are working with.

For me, the focus is on building that understanding one concept at a time.

Before learning how to secure a system, I want to understand how that system works, how it communicates, how it stores information, and how it can fail.

That is the foundation I want to build as I continue my cybersecurity journey.

What fundamental IT skill are you currently working on?

I'd be interested to hear what other people learning cybersecurity are prioritising, especially those who are building their knowledge from the ground up.

Active Directory, User Account Management & Group Policies

Mishy Techie — Mon, 11 May 2026 14:42:27 +0000

What Is Active Directory?

Active Directory (AD) is a directory service created by Microsoft for Windows domain networks. It holds information about network resources like users, computers, printers, and shared folders. This allows administrators to manage these resources from a central location.

Launched with Windows 2000 Server, Active Directory has become a common solution for managing identities and access in enterprises.

Key Components of Active Directory

Domain

A domain is a logical group of network objects, such as users and computers, that share the same Active Directory database.

Example:
company.local
school.edu

Domains provide centralized authentication and authorization.

Domain Controller (DC)

A Domain Controller is a server that runs Active Directory services. It verifies user identities and enforces security policies.

Functions of a DC include:

User authentication
Policy enforcement
Directory searches
Replication of directory data

Organizational Unit (OU)

An Organizational Unit is a container used to arrange users, groups, and computers within a domain.

Administrators use OUs to:

Delegate administrative tasks
Apply Group Policies
Organize departments or locations

Example:
HR Department
Finance Department
Nairobi Branch

Forest and Tree

A forest is the top-level structure in Active Directory that contains multiple domains. A tree is a collection of connected domains that share a common namespace.

Features of Active Directory

Centralized Management

Administrators can manage all users and devices from a single location.

Authentication and Authorization

AD verifies user identities and defines access permissions.

Scalability

It supports both small businesses and large enterprises with thousands of users.

Security. Active Directory improves security through:

Password policies
Multi-factor authentication
Access controls
Audit logs
Single Sign-On (SSO): Users log in once and access multiple resources without needing to log in again.

User Account Management

What Is User Account Management?

User account management means creating, changing, monitoring, and deleting user accounts in a network. It ensures users have the right permissions and access to organizational resources.

In Active Directory environments, administrators usually manage accounts using:

Active Directory Users and Computers (ADUC)
PowerShell
Microsoft Entra tools
Administrative consoles

Types of User Accounts

Administrator Accounts: These accounts have higher privileges to manage systems and users.
Standard User Accounts: Regular employee accounts with limited permissions.
Service Accounts: These are used by applications and services to communicate securely.
Guest Accounts: Temporary accounts with limited access.

Common User Account Management Tasks

Creating User Accounts

Administrators create new accounts for employees with details like:

Username
Password
Department
Email address
Modifying User Accounts

Changes may include:

Password resets
Department transfers
Role updates
Disabling Accounts
Accounts are disabled when:
Employees leave
Accounts are compromised
Temporary suspensions occur
Deleting Accounts

Unused accounts should be removed to lower security risks.

Best Practices for User Account Management

Principle of Least Privilege: Users should get only the permissions they need for their job functions.
Strong Password Policies. Organizations should enforce:
Minimum password length
Complexity requirements
Regular password updates
Multi-Factor Authentication (MFA): MFA adds an extra security layer beyond passwords.
Regular Auditing: Administrators should check: Inactive accounts Failed login attempts Privileged accounts Account Lifecycle Management

Proper onboarding and offboarding procedures improve security and compliance.

Group Policies

What Is Group Policy?

Group Policy is a feature in Windows that lets administrators set and enforce rules for users and computers in an Active Directory environment.

Group Policies simplify large-scale administration by automatically applying rules and settings across systems.

Group Policy Objects (GPOs)

A Group Policy Object (GPO) is a set of settings that control:

Security options
Desktop configurations
Software installations
Windows updates
Login scripts

GPOs can link to:

Sites
Domains
Organizational Units

Types of Group Policies

Computer Configuration Policies

These apply to computers no matter who logs in.

Examples:

Firewall settings
Software deployment
Windows updates

User Configuration Policies

These apply to user accounts.
Examples:

Desktop wallpaper restrictions
Start menu settings
Folder redirection

Benefits of Group Policies

Centralized Administration: Administrators manage settings from one console.
Improved Security
Policies enforce:

Password rules
Account lockout settings
Device restrictions Consistency: All users and devices receive the same settings. Reduced Administrative Work: Automation lowers the need for manual configuration tasks.

Common Group Policy Examples

Password Policies

Organizations can enforce:

Password complexity
Expiration periods
Account lockout thresholds
USB Device Restrictions: Administrators can block unauthorized USB devices.
Software Deployment: Applications can be automatically installed on company computers.
Desktop Restrictions: Users can be prevented from changing system settings.

Relationship Between Active Directory and Group Policies

Group Policies rely on Active Directory structures. Administrators apply policies to domains or OUs, allowing precise control over users and computers.

For instance:

Finance users may have stricter security policies.
IT staff may have administrative privileges.
Branch offices may have location-specific settings.

This integration makes managing enterprises more efficient and scalable.

Security Challenges and Considerations

Even though Active Directory is powerful, poor management can create security risks.

Common Threats

Weak passwords
Privilege escalation
Unpatched systems
Phishing attacks
Misconfigured permissions
Security Recommendations
Use MFA
Regularly update systems
Monitor administrator accounts
Apply Zero Trust principles
Conduct security audits

Modern Developments

Nowadays, organizations increasingly connect Active Directory with cloud services such as:

Microsoft Entra ID
Hybrid cloud environments
Identity federation systems

This provides secure remote access, cloud authentication, and modern identity management strategies.

Conclusion

Active Directory remains one of the key technologies for managing enterprise networks. By using effective user account management and suitable Group Policy settings, organizations can maintain strong security, boost operational efficiency, and simplify IT administration.

As businesses continue to adopt cloud and hybrid infrastructures, understanding these technologies becomes more important for IT professionals, system administrators, and cybersecurity specialists.

Basic Networking Explained

Mishy Techie — Mon, 04 May 2026 11:53:27 +0000

In today’s world knowing the basics of networking is super helpful. When you browse the internet stream videos or work from home several key technologies work behind the scenes to keep everything running smoothly. This guide explains four networking concepts. TCP/IP DNS, DHCP and VPNs.

What is TCP/IP?

TCP/IP stands for Transmission Control Protocol/Internet Protocol. It is the foundation of the internet and most modern networks. TCP/IP is like a team that helps your device talk to devices on the internet.

IP (Internet Protocol) gives devices an IP address, like a home address that tells data where to go.
TCP (Transmission Control Protocol) makes sure data is delivered correctly and in the order.

When you send or receive data online like loading a website TCP/IP works together to break the data into packets send them across networks and reassemble them correctly at the destination. TCP/IP is crucial for communication.

What is DNS?

DNS stands for Domain Name System. It acts like the internet’s phonebook. DNS helps you access websites using to-remember domain names instead of complicated IP addresses.

Here’s how DNS works:

Your device sends a request to a DNS server.
The DNS server translates the domain name into an IP address.
Your browser uses that IP address to connect to the website.

DNS makes browsing the web much easier.

What is DHCP?

DHCP stands for Dynamic Host Configuration Protocol. It automatically gives IP addresses to devices on a network. When you connect your phone or laptop to Wi-Fi, DHCP:

Assigns your device an IP address
Provides subnet mask and gateway information
Ensures there are no conflicts with devices

This makes it easy to connect to the internet without configuring network settings.

What is a VPN?

A VPN or Virtual Private Network, is a tool that keeps you private online. When you use a VPN:

Your internet traffic is encrypted
Your IP address is. Replaced
Your connection is routed through a secure server

VPNs are especially useful when using Wi-Fi as they help protect your data from hackers and surveillance. People also use VPNs to access restricted content or stay online. VPNs are a tool for online security.

Why These Concepts Matter

TCP/IP DNS, DHCP and VPNs are the building blocks of networking.

TCP/IP ensures communication between devices.
DNS makes the internet user-friendly by using domain names.
DHCP simplifies device connectivity by assigning IP addresses.
VPNs protect your privacy and data when you’re online.

Understanding these basics can help you fix network issues improve your security and build a foundation for IT knowledge. Knowing TCP/IP DNS, DHCP and VPNs can make a difference, in how you use the internet.

From Basic CRUD Ticketing Systems to AI-Powered Support

Mishy Techie — Mon, 27 Apr 2026 13:19:51 +0000

Ticketing systems have been the backbone of IT support, customer service and internal operations for a time. At their core they help track, manage and resolve issues in a way. But modern ticketing systems are not about logging requests. They are evolving into smart platforms that make things more efficient, automate tasks and improve user experience.

Fuctions of a Ticketing System

Creating tickets (issues, requests, incidents)
Tracking status. Progress
Assigning tickets to agents or teams
Keeping a record of communication
Closing and resolving issues

A simple frontend application can show these basics through CRUD (Create, Read, Update, Delete) functionality.. Real-world systems go much further.

Moving Beyond CRUD

Ticketing platforms focus on workflow efficiency. Key enhancements include:

Status pipelines (Open → In Progress → Resolved → Closed)
Priority and SLA management to handle issues first
Tagging for better organization
Search and filtering for access to relevant tickets

These features turn a basic list into a functional operational tool.

Modern Technologies Shaping Ticketing Systems

1. Frontend Frameworks

Frameworks like Vue.js, React and Angular make dashboards interactive. Real-time updates, component-based architecture and responsive UI design make it easier for support teams to use.

2. Backend and APIs

Modern systems use API-driven architectures with tools like Node.js or backend-as-a-service platforms like Firebase and Supabase. These provide authentication, databases and scalable infrastructure with setup.

3. Real-Time Capabilities

With technologies like WebSockets and real-time databases ticket updates are reflected instantly across users. This is critical for environments where multiple agents handle tickets at the same time.

4. Cloud and Microservices

Cloud platforms make ticketing systems scalable. Integrate with other services. Microservice architectures make it easier to extend functionality without affecting the system.

5. AI and Automation in Ticketing Systems

Artificial intelligence is transforming ticketing systems in ways making ticket management smarter:

Automated ticket classification using AI
Suggested responses for agents using AI
Chatbots for handling queries with AI
Predictive analytics for workload management with AI

AI reduces effort and speeds up resolution times especially in high-volume environments where ticketing systems handle many requests.

6. Security and Access Control

Modern systems implement authentication, role-based access control. Secure APIs. These ensure that sensitive data is protected and only accessible to authorized users.

Simple Systems are Useful for:

Learning and prototyping ticketing systems
Demonstrating CRUD operations in ticketing systems
Designing UI/UX workflows for ticketing systems

The Future of Ticketing Systems

The direction is clear: ticketing systems are becoming smarter, more automated and deeply integrated into operational ecosystems. The focus is shifting from managing tickets to optimizing the entire support process in ticketing systems.

Developers building ticketing systems today should think beyond functionality and consider scalability, automation and user experience from the start when creating ticketing systems.

Conclusion

Ticketing systems are evolving from issue trackers into intelligent support platforms. By combining frontend frameworks, scalable backend services and AI-driven automation in ticketing systems developers can build systems that not only manage issues but actively improve how organizations respond to them with efficient ticketing systems.

AI Agents impact on jobs in Africa

Mishy Techie — Thu, 23 Apr 2026 09:58:35 +0000

This is a submission for the Google Cloud NEXT Writing Challenge

Across Africa millions of people are building careers from their phones—freelancing, coding, creating content and running online businesses. From Nairobi to Lagos the hustle is digital, fast and constantly evolving.

A new shift is coming.

With the rise of AI agents powered by tools like Google Gemini work is no longer about what you can do—it’s about how well you can direct intelligence to work for you.

Automation: The Real Game Changer

The biggest shift isn’t assistance, it’s automation.

AI agents can handle time-consuming tasks independently:

Managing customer inquiries
Organizing schedules
Running business workflows

For small business owners and freelancers in Africa this is huge.

It allows individuals to scale their work without hiring teams reducing costs while increasing productivity.

Why This Matters for Africa

Africa has always been quick to adapt to first technology. Many people skipped infrastructure and went straight to smartphones, mobile banking and online work.

AI agents fit perfectly into this ecosystem.

They:

Require setup
Work well on devices
Enable global competitiveness

A freelancer in Nairobi, Lagos or Accra can now compete with professionals—not by working harder but by working smarter with AI.

This could redefine opportunity across the continent.

Challenges to Consider

Despite the opportunities there are challenges:

Internet access and affordability
Limited awareness and AI literacy
Risk of over-reliance on automation

Addressing these will be key to ensuring that AI benefits as many people as possible.

EcoMark - Discover your environmental footprint

Mishy Techie — Sat, 18 Apr 2026 08:26:15 +0000

This is a submission for Weekend Challenge: Earth Day Edition

EcoMark – A Simple Way to Reflect on Our Carbon Footprint

What I Built

For this challenge, I built EcoMark, a lightweight web app that helps people quickly understand their everyday environmental impact.

The idea was simple:

Most of us care about the planet, but we don’t always know how our daily habits translate into real impact.

EcoMark bridges that gap by turning a few lifestyle choices into a clear, understandable carbon score, along with practical suggestions for improvement.

Users answer a few short questions about:

How they get around
What they eat
Their energy usage
Their shopping habits

Based on this, the app calculates a score and places them into a category:

Green Hero
Improving
High Impact

To make it more useful (and less judgmental), the app also generates personalized tips to help users reduce their footprint in realistic ways.

Demo

👉 Try it here:

EcoMark

Video

Code

The project was built and deployed using:

JavaScript
HTML/CSS
Google Gemini API
Replit (development + hosting)

View Source Code

How I Built It

I approached this project with a focus on simplicity, clarity, and usability, especially since many users might access it on mobile devices.

1. Carbon Scoring Logic

Instead of trying to build a scientifically perfect calculator, I designed a simple scoring system that reflects relative impact:

Higher-emission activities (e.g., frequent car use, meat-heavy diets) increase the score
Lower-impact choices (walking, plant-based diets) reduce it

This keeps the experience intuitive while still meaningful.

2. Backend with JavaScript

I used JavaScript to:

Handle form input
Process user responses
Calculate the carbon score
Render results dynamically

3. AI-Powered Suggestions with Google Gemini

One of the most interesting parts of this project was integrating the Google Gemini API.

Instead of hardcoding advice, I generate tips dynamically based on the user’s score.

Higher scores → stronger, more impactful suggestions
Lower scores → reinforcement of good habits

This made the app feel more:

Personalized
Engaging
Practical

4. Building with Replit

Since I didn’t have access to a full development setup, I built everything directly in Replit.

This influenced my approach:

Keeping the architecture simple
Avoiding unnecessary dependencies
Prioritizing fast iteration

It turned out to be a great way to go from idea → working product quickly.

5. Design Choices

I intentionally kept the UI:

Clean
Minimal
Mobile-friendly

The goal was to make the experience feel approachable rather than overwhelming.

What I Learned

This project reminded me that:

You don’t need complex systems to communicate important ideas
AI works best when it enhances—not replaces—core logic
Constraints can lead to better, more focused solutions

Future Improvements

If I had more time, I’d love to:

Add location-based recommendations
Improve scoring accuracy
Include visual progress tracking
Let users compare lifestyle scenarios

Final Thoughts

EcoMark isn’t meant to be a perfect measurement tool.

It’s a conversation starter—a small way to help people reflect on their habits and take simple steps toward a more sustainable lifestyle.

Small changes, multiplied by many people, can make a real difference.

Thanks for reading!
