This malicious code 101 workshop will focus network attack investigations and analysis. Investigating network attacks requires skills beyond interpreting log files and analyzing alarms generated by cyber security products. Come join us in an interactive and collaborative session focused on investigating and analyzing network based attacks. This session is designed to introduce participants into the world of network forensic analysis and discerning attack techniques and sequences using nothing but network captures or traces. There is nothing super fancy required for this session other than bringing your laptop, your favorite network analysis tools such as Wireshark, and a ready to have some fun while learning and collaborating attitude.
