Shecurrently performs leading-edge security consulting and works inresearch and development to advance the state of the art in infor-mation systems security. Angela has over a decade ofexperience in information technology, with a focus on perimeterdefense, secure network design, vulnerability discovery, penetrationtesting, and intrusion detection systems.

She has a Masters inComputer Science, and is currently pursuing her Ph. Angela has a wealth of knowledge from industry,academia, and government from her consulting experience withprominent Fortune companies, the Department of Defense,dot-com startups, and universities. She is a frequently invited speakerat a variety of conferences and security events. He has contributed protocol dissectors as well as core logic toEthereal. He is a Technical Leader at Cisco Systems, where he works ontools and builds systems.

Gilbert is a family man, a linguist, a want-to-bechef, and a student of tae kwon do. He has held positions in networking, systems, andsecurity over the past seven years in the technology, financial, and mediasectors. A graduate of the business school at the University of Washington,Josh concentrates on balancing technical and business needs for companiesin the many areas of information security. He also promotes an inclusive,positive security philosophy for companies, which encourages communi-cating the merits and reasons for security policies, rather than educatingonly on what the policies forbid.

Josh is an expert in open-source security applications such as Snort,Ethereal, and Nessus. He also enjoys reading about the mathematics andhistory of cryptography, but afterward often knows less about the subjectthan when he started. More of Larrys writing, guides, and rants can be foundon his blog at www. Originally from Oklahoma, Greg has spent over 25 years in the computerindustry. Although Greg has a degree in management, his passion is to becreative.

This is what the software development process provides. His vastexperience includes hardware and software troubleshooting on mainframe,midrange, and PC computers. Gregs early roots in software developmentwas in database technologies, dabbling in C and assembly, but mostlyworking with a language called Clipper by Nantucket. Gregs work onEthereal began in November of Since that time he has made a sig-nificant number of contributions to the Ethereal now Wireshark project.

Greg has actively developed cus-tomer and internal training programs for a number of different Novellproducts. One of his most unique programs was developed to teachinternal users the skills necessary to analyze packet traces. Greg startedworking with packet traces many years ago with Novells LANalyzerproduct. From there Greg migrated to Network Associates Sniffer product. The author of sev-eral papers on wireless security and intrusion analysis, Joshua has alsowritten open-source tools designed to highlight weaknesses in wirelessnetworks.

When not breaking wire-less networks, Josh enjoys working on his house, where he usually ends upbreaking things of another sort. Jay Beale is an information security specialist, well known for his workon mitigation technology, specifically in the form of operating system andapplication hardening. Hes written two of the most popular tools in thisspace: Bastille Linux, a lockdown tool that introduced a vital security-training component, and the Center for Internet Securitys Unix ScoringTool.

This pane provides all of the details for each of the layers contained inside the captured packet in a tree-like structure. Clicking on various parts of the protocol tree will highlight corresponding hexadecimal and ASCII output in the bottom pane. Clicking on various parts of this data will also highlight the corresponding fields in the protocol tree in the middle pane.

Notice that highlighting the source MAC address in the middle, protocol view pane, automatically highlights that portion of the hexadecimal dump in the bottom data pane. This data can then be saved or printed. A good use for this can be to reconstruct a web page. Just follow the stream of the HTTP session and save the output to a file. You should then be able to view the reconstructed HTML offline, without graphics of course, in a web browser. Notice how easy it is to read the username and password in cleartext.

This is a good example of why you would never want to Telnet as root! Ethereal has the ability to use both capture filters and display filters. The capture filter syntax follows the same syntax that Tcpdump uses from the libpcap library. This is used on the command line or in the Capture Filter dialog box to capture certain types of traffic.

Display filters provide a powerful syntax to sort on traffic that is already captured. As the number of protocols grows, the number of protocol fields for display filters grow as well. However, not all protocols that Ethereal currently supports have display filters. Also, some protocols provide display filter field names for some of their fields, but not all of their fields.
