CIS 145

Module 6 Summary

In Module 6, I learned a lot about internet security, starting with encryption methods. Private key encryption uses the same key, while public key encryption involves two keys—one public and one private. What’s interesting is that only the private key can unlock messages encrypted with the public key, so you never have to share that private key, which adds a strong layer of security. I also learned about key strength and gained a deeper understanding of DOS attacks, which I was already somewhat familiar with. One of the most interesting things was learning about active content blocking. It acts like a security guard for your browser, allowing you to control how specific pieces of code run, giving you an extra layer of protection. Most of the cybersecurity topics, like anti-malware and firewalls, were things we already touched on in Appendix A, but this module gave a deeper dive into how these systems work together to protect us.
