A SIEM is a technology that helps organizations collect, analyze, and manage security event data from various sources to detect and respond to potential security incidents.
They are used by security operations teams, incident response teams, and security analysts to monitor and manage security events and incidents, and to investigate and mitigate potential security breaches. SIEMs collect and correlate log data, security events, and other relevant information from sources such as firewalls, intrusion detection systems (IDS), security appliances, servers, endpoints, and applications.
