A great network protocol analyzer to start with is WireShark.Watch Now This tutorial has a related video course created by the Real Python team. Therefore, if it's going to be used in a switched network environment, then it's only going to detect the traffic that’s local to the switch. After all, NPA will only be capable of capturing and decoding data it can actually understand.

It's essential that the Network Protocal also supports flexible filtering that’s capable of allowing triggered notifications. On top of that, the NPA should also be capable of capturing and decoding all protocols from every type of media, including 802.11, WAN, Ethernet, etc) on which the corporate data flows. When used as a corporate security tool, it's important to keep in mind that a NPA needs to be distributed since this is going to make it possible for it to cover all of the network's areas.

Choosing and implementing a network analyzer However, when a packet sniffer is used for the right purpose it proves itself to be a perfect resource for your network. Software wifi packet sniffers are most commonly used for either the invasion of privacy or others for monitoring server traffic, where as hardware wifi packet sniffers are most commonly used for diagnostics and monitoring for performance and security related purposes. Hardware is used for packet sniffing typically works just like a router, where as software based wifi network analyzers run on the devices being monitored. Wifi network analyzers come in hardware, as well as software versions. What types of Wifi Network Analyzers are there? A network protocol analyzer is a combination of programming and hardware and in certain cases, a separate hardware device that can be installed in a network or computer in order to improve its security level against viruses and other types of malicious activities.
