A method of security administration known as security information and event management (SIEM) is a system that integrates SIM (security information management) and SEM (security event management) tasks into a single security management system.
The acronym SIEM is pronounced "sim" rather than "sim," despite the fact that it is written with a final e. SIEM (security information and event management) is the process of detecting, aggregating, monitoring, and reporting security-related events in a computer system or network environment.
It can be applied to software, systems, or IT environments. It enables security or system administrators to record and evaluate occurrences, as well as analyze, adapt, and manage the information security architecture, rules, and procedures, as well as the rules and procedures that govern information security.
A SIEM system can be rule-based, or it can use a statistical correlation engine to create relationships between event log items at the most fundamental level of the event log hierarchy. Users and entity behavior analytics (UEBA) are now included in modern SIEM systems, which allows for the orchestration, automation, and response (SOAR) of security incidents (SOAR).
End-user devices, servers, and network equipment, as well as specialized security equipment such as firewalls, antivirus software, and intrusion prevention systems, are all monitored by SIEM systems, which work by deploying multiple collection agents in a hierarchical fashion to gather security-related events. SIEM systems, also known as security information and event management systems, are used to monitor and handle security events (IP Ses).
Event collection points forward events to a central administration dashboard, where security analysts sort through the muddle, connecting the dots, and ranking the importance of security occurrences.
