(The data that ntop can monitor include: network traffic, usage protocol, system load, port condition, data packet sending time, etc. Basically, all incoming and outgoing data are invisible through it. Whether it is used for routine network monitoring or reporting, it is a very excellent tool to make your network traffic transparent. It works like a passive sonar, silently receiving all kinds of information from the network. Through the analysis of these data, the network administrator can deeply understand the current operation of the network. However, since ntop is essentially a sniffer, it is a double-edged sword. How to ensure that such information can only be obtained by authorized persons will become particularly important.)
