“Network Security: Content Quality, Course Structure, Practical Application, Instructor Quality, Pacing and Difficulty, Assessments”
The Network Security course was well-organized and covered key concepts like firewalls, encryption, and VPNs in great detail. The hands-on labs with tools like Wireshark and packet sniffers were particularly helpful for applying theoretical knowledge. The instructor was knowledgeable but could improve on pacing, as some sections felt rushed.
