One provider offering packet sniffing and web analytics solutions is AthTek NetWalk. Some sites, such as the SiteSpect use a interesting way to take advantage of packet sniffers, use the technology for multiple testing, eliminating dependence on the markup of a web page for testing.
One has to follow five steps to collect data through packet sniffing:
1. Client types your URL in a browser.
2. The request goes through a packet sniffer software or hardware which includes attributes of the application which can send back more data about the visitor packet sniffer.
3. Since then the request is routed to the web server by the packet sniffer.
5. The packet sniffer sends the page in the visitor’s browser.
The benefits of using packet sniffer and their mechanism of data collection are:
4. The nature of the solutions is such that it will be able to use only first part of “cookies.”
Packet sniffing has certain limitations, the data collectors should be aware of.
1. Most companies find it difficult to make a case and convince the IT department to add an additional layer of software on Web servers or the physical installation of hardware in their data centers, high-profile route all web traffic through these solutions. Sniffers also create a layer between the client and the website, which can pose problems and create obstacles.
2. Packet sniffing packet includes collecting raw traffic internet web server, which can pose two problems: (1) non-trivial amounts of work package configuration solutions detectors to filter only the data needed for all raw data. (2) The second challenge is about privacy. The raw data captures all data, including personally identifiable information such as passwords, names, addresses and credit card numbers. Privacy minutes required stress testing and legal review.
4. If someone has a lot of web servers or clients, he may be felt in many networks, packet sniffing can be expensive because the packet sniffing solution would have to be installed in the software or hardware on all networks.
