  3. information visualization is the use of interactive, sensory representations, typically visual, of abstract data to reinforce cognition. http://en.wikipedia.org/wiki/Information_visualization

  4. An Art Survey… A B C http://www.clifford.at/cfun/progex/ http://www.muppetlabs.com/~breadbox/bf/ http://www.geocities.com/h2lee/ascii/monalisa.html http://www.artinvest2000.com/leonardo_gioconda.htm

  5. Why InfoVis? Views • Patterns • Anomalies • Comparisons • Outliers/Extremes • Big Picture & Details • Interaction • Large Datasets Replies

  6. TCP Dump Packet Capture Visualizations EtherApe Ethereal Tcpdump image: http://www.bgnett.no/~giva/pcap/tcpdump.png TCPDump can be found at http://www.tcpdump.org/ Ethereal image: http://www.linux-france.org/prj/edu/archinet/AMSI/index/images/ethereal.gif Ethereal by Gerald Combs can be found at http://www.ethereal.com/ EtherApe image: http://www.solaris4you.dk/sniffersSS.html Etherape by Juan Toledo can be found at http://etherape.sourceforge.net/

  7. So What? • Go Beyond the Algorithm • Complement current systems • Make CTF a Spectator Sport • Enhance forensic analysis • Mine large datasets • Logs • Monitor in real time • Allow big picture, but details on demand • Fingerprint attacks/tools (people?) • Alerts (2-3 Million /day) • Observe attacker behavior (example) What tasks do you need help with?

  26. TCP/IP SequenceNumber Generation Michal Zalewski Linux 2.2 TCP/IP sequence numbers are not as good as they might be, but are certainly adequate, and attack feasibility is very low. Linux 2.2 TCP/IP sequence numbers are not as good as they might be, but are certainly adequate, and attack feasibility is very low. x[n] = s[n-2] - s[n-3] y[n] = s[n-1] - s[n-2] z[n] = s[n] - s [n-1] x[n] = s[n-2] - s[n-3] y[n] = s[n-1] - s[n-2] z[n] = s[n] - s [n-1] Follow-up paper - http://lcamtuf.coredump.cx/newtcp/ Initial paper - http://razor.bindview.com/publish/papers/tcpseq/print.html
