With the Wireshark network analyzer, networking pros can address a wide range of monitoring for functions that range from bandwidth optimization and application analysis to troubleshooting and network security. Wireshark is an open source network monitoring tool, so networking pros can tailor the tool to their exact needs. And those needs can range from basic traffic transmission testing to intrusion prevention, analysis of bandwidth usage, application security testing and identification of faulty configurations.
In "Wireshark Network Analysis: The Official Wireshark Certified Network Analyst Guide," Wireshark expert Laura Chappell explores capturing and analyzing various types of traffic, application-specific monitoring, WLAN and VoIP monitoring, and more.
