Description of technology

The monitoring project consists of a network hierarchy (a tree-like device group hierarchy) manually created by the user and/or by means of scanning tools, and of monitors representing the basic element of network monitoring.

Network monitoring involves a variety of checks for each device in the network and an appropriate response according to results of these checks. Each device includes monitors manually created by the user.

Моnitor is a combination of a specific sensor with its parameters, a list of actions that are executed according to the results of the sensor check, and authorization credentials for some types of sensors.

Network monitoring includes management of all project monitors and logging of their operations. Monitor operations consist of the execution of sensor checks at certain time intervals and of the execution of actions according to the conditions and check results. Logging is carried out according to executed sensor checks and actions.

Potential risks

There are some rare problems in operation of TCP sensors. For the moment they are under examination and debugging process. The problems are related to large numbers of monitors deploying TCP sensor checks.

Encrypted passwords (for authorization in computers or services) are stored in the monitoring project file. Symmetrical proprietary block cipher is deployed in the program.
