“I loved how easily the classes were and how quickly everything was loading which made it easy. The topic was perfectly executed. Liked the examples. The class finished much quickly than anticipated.”
I liked all of it. At first, I thought cybersecurity was just about installing antivirus software and calling it a day, but boy was I wrong. We learned about all these different types of attacks, like phishing and ransomware, and how they can compromise our personal info and even take down entire systems. One of the most surprising things I learned was how easy it is to fall victim to a phishing attack. I mean, I thought I was pretty savvy, but some of the examples we saw in class were so convincing, I could see how easily someone could get tricked. We also learned about the importance of strong passwords and how to create them. I have to admit, I was guilty of using the same password for multiple accounts, but now I know better. The whatsapp attack that i have never heard before were really interesting. I never realized how much work goes into keeping our data safe online. Overall, I'm really glad I took this class. It's made me so much more aware of the potential threats out there and how to protect myself.

“The introduction to cybersecurity is clear and informative, but adding real-world examples could enhance engagement and urgency.”
The introduction to cybersecurity offers a solid overview of the importance of safeguarding digital assets. It effectively outlines key concepts, potential threats, and best practices. However, to enhance engagement and understanding, incorporating real-world examples and current statistics would be beneficial. This would not only illustrate the relevance of cybersecurity but also highlight the urgency of adopting protective measures in today’s digital landscape, making the content more relatable and impactful for the audience.
