• Listening to the network interface
• Connecting through an existing circuit break
• Tapering outgoing and incoming traffic and then redirecting the data to the sniffer, etc.

Sniffers are mainly used for spying purposes. By accessing the traffic, they give attackers access to passwords, correspondence and other information that is not encrypted. Among programmers, such programs are used for good purposes as well; they allow detecting various problems in network security on Windows, Linux and other operating systems.

Traffic analyzers are used to:

• Comprehensive network security audit;
• Malware detection such as worms, Trojans and other malware
• Detect and fix problems with looped traffic.

It is worth remembering that looped traffic has a negative impact on the performance of network equipment due to excessive load.

The best WiFi sniffers

All network traffic analyzers can be divided into two categories. The first type of software is used as the network core in the operating system, which collects data about network traffic. The other type of software is designed directly to analyze the received data. It is important to remember that even a small amount of incoming and outgoing Internet traffic generates thousands of packets, which without special software is difficult to navigate. Programs for data collection are virtually no different from each other because they work on a similar principle. Programs for analysis differ in the method used to verify the collected information.

On our site you will find proven free programs for traffic analysis, which can be used at home, as well as to detect problems with network security in enterprises, offices, etc. To download sniffers, all you need to do is to choose the type of software you want to use.
