CIS 370 - Network Forensics and Investigations

5 Credits
Students must be admitted to the appropriate BAS program to take this course. It is assumed that they have completed CIS 155 or its equivalent. This course focuses on tracking down network intruders or at least ascertaining how they got in and what they did. Intruders can be internal or external attackers. When, what, where, and how they were able to gain access gives a network administrator clues to design flaws in the network architecture and shortcomings in policies or procedures. An introduction to investigations in the cloud is included along with the legal aspects of network investigations. This is a hands-on class in which students test network forensics tools and how to use them in internal or external investigations.
