• SIM (Security information management)
• SEM (Security event management) - Security event management. SIEM technology provides real-time analysis of security events (alarms) originating from network devices and applications.

To identify infections that have already occurred, which the company is not yet aware of, there is a class of SIEM (Security information and event management) protection systems. They analyze events in security systems, respond to suspicious operation of network equipment and applications, issue alerts about attacks. The best of them do it in real time. The experience of many SIEM vendors shows that often already pilot implementations identify various malware on customer networks, including spyware that has not been detected by other security tools.

SIEM software products are able to analyze the state of information security in IT systems, in real time, generate alerts, respond to the operation of network equipment and applications. The overall goal of this category of products is to help companies quickly respond to attacks, security incidents, and organize the information that is handled as part of this task.

SIEM is an improved system for detecting malicious activity and various system anomalies. SIEM allows you to see a more complete picture of network activity and security events. When conventional detection tools do not individually see an attack, but it can be detected by careful analysis and correlation of information from various sources.
