Packet Capture and Analysis

There are a variety of tools, many of them freeware, that have packet capture and analysis components. In years past, the use of encryption on the internal network was infrequent, and access to a packet analyzer had security implications. In older versions of Windows, even passwords being transmitted across the network were sent in clear text, leaving them at high risk to an unauthorized user of a sniffer hanging off the trusted network. As more and more regulations provide incentives for organizations that encrypt data, and with IPSec a native function as part of modern operating systems, the use of packet analyzers has become more complicated. This technology can be very helpful to network administrators who need to troubleshoot problems as well as to information security professionals seeking to understand traffic that travels across the network.
