With wireless communications occupying an increasingly important portion of general networking, familiarity with wireless protocols and related topics (survey, security, monitoring, and analysis) is likewise moving to center stage for those interested in protocol analysis work. Interestingly, both Wireshark and AirMagnet products use the AirPCap driver to permit protocol traces to be captured from wireless network traffic. NetScout is touting this new program as a replacement for and successor to the Sniffer Certified Professional (SCP) program, offering discounted upgrade paths to holders of Sniffer credentials, as well as entry-level training and certification and its own certification ladder for nGenius users who lack prior Sniffer credentials.įinally, the AirMagnet certifications are likely to be of interest to anyone who uses those products for wireless network survey, analysis, and troubleshooting tasks. Some form of the Windows Promiscuous mode capture (WinPcap) driver is needed to enable Wireshark to do its packet-capture thing. Though the various nGenius successors to the Sniffer program are also great credentials, they require access to and knowledge of the NetScout products, whereas Wireshark will run on any Windows PC for which a suitable network driver is available. (Note: The author, Laura Chappell, is also the founder of Wireshark University and a well-known protocol expert.) Wireshark Network Analysis: The Official Wireshark Certified Network Analyst Study Guide is a lengthy, detailed guide, and Wireshark Certified Network Analyst Official Exam Prep Guide is a shorter, more focused book for exam preparation. In 2010, the Protocol Analysis Institute published two books by Laura Chappell on the Wireshark CNA, as this certification is sometimes called.
