The ability to actually control and interfere with all equipment considered critical on the network and system side is called monitoring. Communication Monitoring is provided via Simple Network Management Protocol (SNMP). Large corporate companies have a wide variety of network and security technologies. These technological structures must be maintained in a quality and appropriate manner. The assets and data stored and controlled can be critical. In addition, when errors occur in the system, there should be a warning mechanism and an informative message should be sent to the responsible persons. After these messages, actions can be taken very quickly depending on the situation and the incident. It can report all data movements such as security vulnerabilities, updates, attacks and threats within the structure. The reporting process can be organized daily, weekly, and monthly, and then improvements can be made as needed.

Seen as a more advanced system, SIEM offers more detail and reporting options than log analysis. One of the most important features of SlEM is software that helps detect possible attacks by making meaningful connections between seemingly independent events with the help of defined policies and rules.
