For The Love of Network Protocols and The Command Line

If there’s one thing that a Cybersecurity student should learn, it’s network protocols … IP, TCP, HTTP, SMTP, Telnet, DNS, and so on. The ability to understand the key elements of a network connection must be at the core of their education. In many cases, we thus want to be able to detect something coming in or leaving our network, and possibly log or block it. We also need to search for things. For this, we often are trying to find the needle in the haystack, and then determine timelines of activity.
