How does a network monitoring system work?

The collection scope of the TOOM public opinion monitoring system includes but is not limited to newspapers and periodicals, forums, blogs, Weibo, WeChat public and other information, and automatically filters invalid data, and the collection frequency needs to reach the minute level at the earliest, which can achieve 24/7 uninterrupted automatic collection. The number of daily collection and updates reaches millions, and the system supports cloud computing storage and retrieval of big data.

With the automatic discovery of collection tasks and dynamic tracking mechanism, it can achieve the whole network crawling within a limited range, and can crawl keyword information through general search engines such as automatic call of keyword setting, Google, 360, etc., to further expand the scope of monitoring.

It also collects data from the whole network; A large number of acquisition servers are used to ensure the efficient operation of the system and rapid response. The collected data is stored on the enterprise's data server. The final dataset is displayed through a series of work cycles such as data capture, data cleaning, data similarity and merging through various data mechanisms.

The collected data is analyzed and statistically related to the indicators, and the deep and hidden useful information of the data is rediscovered for the second or even multiple times. Provide users with convenient data and social services, such as push, early warning, etc.

In the network, when the information is disseminated, the network can be connected by using tools to set the network interface in the mode of monitoring.

The information that is being transmitted is intercepted or captured, so as to carry out the attack. Network snooping can be implemented in any location mode in the network.

Implementation. Hackers generally use network snooping to intercept user passwords. For example, when someone occupies a host, then he wants.

If they want to expand the results of the battle to the entire LAN where this host is located, listening is often the shortcut they choose. A lot of the time I'm in all kinds of An.

I saw some beginner enthusiasts on the whole forum, and they thought that if they occupied a host, they should want to enter its intranet.

Simple. In fact, it is not easy to enter a host and then transfer to other machines in its internal network. Cause.

In addition to getting their passwords, there is also an absolute path that they share, and of course, there must be a write at the end of this path.

permissions. At this point, running a listener on a host that is already being controlled can be very effective. But it's a lot of work.

It also requires the parties to have enough patience and adaptability.

Taking imonitor eam as an example, the whole monitoring system is divided into three parts, the monitoring side, the server side and the client.

The monitoring program and the server program should be installed on the server or administrator's computer, the server program is used to store the logs collected from the employee's computer, and the monitoring program is used to view the log records stored in the server and monitor all client computers in real time.

The client program should be installed on the employee's computer that you want to monitor to collect records of the employee's computer operation.

The services that are monitored are generally services that need to run stably for a long time on the network, the most common ones are ** (users get relevant information by visiting their pages), mail services (users send and receive emails through clients or pages), FTP services (users save data files on the server through FTP client software or FTP standard protocol, and can be used from other locations) and so on.

Monitoring, in general, is to draw conclusions by technically simulating a user's visit and by analyzing the response to the request and comparing it with the normal response.

The monitoring (source) can be a monotoring tools program installed on the administrator's (webmaster's work computer), which acts as **; It can also be to purchase services from monitoring service providers, which are specified by the service provider according to the customer's information, simulating the geographical distribution of real users from the Internet, physical routing and other specific conditions;

Network monitoring 1 (also known as network monitoring) is a service that monitors specific targets on a network.
