This lecture was very helpful in understanding information security systems.

When it comes to security solutions, firewalls, SIEM, DLP, and XDR are probably the well-known ones, but I learned that there are actually many more security solutions out there, and I was able to easily understand what role each one plays through analogies. You pointed out what to watch out for when implementing each solution and what the latest trends are, which helped me understand the various solutions.

This is a lecture that gives you the confidence to move on to advanced topics. It was very helpful in understanding overall security. Thank you.
