Oostende cheap hotelsEvery Internet-based attack is transported using Internet Protocol (IP), so an in-depth understanding of IP and how it works is paramount in defending your network. Why blindly trust a commercial analyzer when you can learn to "read between the lines" yourself? The focus of this course is to train the student on how IP transports and services work, as well as how to distinguish between normal and malicious traffic patterns. Common network attack techniques and the ways to thwart them are discussed in detail, and free tools such as TCPdump and WINdump are demonstrated in class so that students will be capable of putting their new knowledge to work immediately once they return to the office.
Spane HotelsDue to the technical level and pace of these courses, students should already be familiar with TCP/IP fundamentals such as IP addresses; ports; IP protocols such as TCP, UDP, and ICMP; and TCP basics such as flags, sequence numbers, the three-way handshake, and session establishment/teardown. Students should test their basic knowledge of TCP/IP & Hex before attending class (TCP/IP & Hex Quizzes).
