and it ensures system protection by safeguarding critical system files and settings from unauthorized changes.
The class equally allowed me to learn. I also learned about Windows key features such as Windows folders, Linux directories, file permissions (owner, Group & others),
Authentication of a user through login passwords and biometrics gives permissions by controlling exactly what each user and App is allowed to "read," "write," or "execute"; it keeps each process isolated in its own protected box,
Linux is free and open source, while Windows is notβit requires paid licenses.
I also learned at a basic level what operating systems handle in terms of security relevance, such as
They are different operating systems: Windows OS, Linux OS, and Mac OS.
Windows is the most popular type, as more than 75% of desktops use it. Whereas Linux OS is mostly used for servers, security purposes, and by developers.
An operating system (OS) acts as an interface between the user and the computer system by managing communication between the user, applications, and hardware, thus keeping the entire system running as one unified system.
In this class, I learned about the operating system (OS) as the core software that coordinates everything happening on a computer. An operating system is situated between the user, applications, and the computer system's physical hardware.
aimed at dousing tension and putting learners in a relaxed and joyful mood as she did a βrecap of the previous classβ and later introduced the new topic in the Cybersecurity Curriculum Module 1:
"Linux and Windows Fundamentals."

Linux and Windows Fundamentals: Operating System
On the 27th of June, 2026, tutor Ms Favour Onoko, in her signature jovial and amiable disposition, who knows how to make something serious look rather not serious,
Therefore, in One Sentence:
An exploit is the action or code that leverages a vulnerability to achieve unauthorized access, disruption, or other malicious objectives.

Cross-Site Scripting (XSS) is one of the most common and dangerous web application vulnerabilities, allowing attackers to inject malicious scripts (code) into trusted websites. These scripts can steal sensitive data, hijack sessions, or manipulate site content.
There is a simple relationship among these parameters:
Threat = The potential attacker or danger.
Vulnerability = The weakness.
Exploit = The means used to attack the weakness.
Risk = The potential damage resulting from the attack.

Exploit in Cybersecurity
An exploit is a method, tool, technique, or piece of code used to exploit a vulnerability in a system, application, or network.
and phishing training for all employees is sacrosanct.
All told,a strong security culture requires continuous progress, leadership dedication, and collective responsibility across the entire ADT company.

. Undertake a thorough root cause analysis after every incident and implement corrective actions.
. Vishing swept an entire company off its feet, and data was breached,therefore, the provision of regular cybersecurity awareness
It obviously points to weaknesses in employee awareness, vulnerability management, and other technical lapses.
To improve, ADT should:
l Build security-first culture;prioritizing security culture
It showed that security is not given the utmost priority that it deserves. That means post-incident activities from previous incidents were not fully analyzed or used to strengthen defenses.
Strong encryption of data etc
4.ADT Inc , experienced three breaches within 12 months. These repeated occurrences speak volumes. It strongly implied that ADT Incβs internal security culture is not sufficiently effective.
Use of strong passwords and Multi-factor authentication(MFA).
.The provision of regular cybersecurity employeesβ training.
. Bringing in regularly the Red Team(offensive security team) to perform regular vulnerability assessment by legally hacking the system.
they should go back to their drawing board, aimed at fortifying and protecting their back end by:
.Finding out the root cause and addressing the underlying vulnerabilities(weaknesses).
.Frequent patching of the software to check for any vulnerabilities that could be exploited.
