Instead of beginning with an IDS console, the course spends its first two days teaching what instructors call Packets as a Second Language . Students first learn how and why TCP/IP protocols function at the byte level. Only after mastering these fundamentals do they progress to industry-standard tools like Snort, Zeek (formerly Bro), Wireshark, tcpdump, and SiLK.
