    • More Netsim

      You did some Netsim activities in a previous lesson. If you were unable to finish it before, you can try and finish it now. 

      Netsim is a simulator game intended to teach you the basics of how computer networks function, with an emphasis on security.  You will learn how to perform attacks that real hackers use, and see how they work in the simulator!
