What is security information and event management (SIEM) and what is its purpose in information security?
Security information and event management (SIEM) is a security solution that collects log data from servers, endpoints, network devices, applications, systems and other sources. It is a security control that correlates, aggregates, centralizes, orchestrates and analyzes these log data and produces security incidents when security threats are unfolding. And it collects and analyzes log data from all systems and devices in an organization. In addition, it has the ability to correlate incidents and events from systems and devices to provide further details and insights about the security incidents and threats. Moreover, it is used as a central event log processing security solution that correlates events and incidents among different devices and generates alerts that may represent security incidents.
Security information and event management (SIEM) is a security control that continuously reviews, processes and organizes logs from system and devices of the organization in real time and automatically to determine whether security threat, event or incident warranting attention is occurring in the entire systems and infrastructures. In other words, security information and event management is a security solution that collects logs from the devices and systems of the organization, correlates the log data, and generates alerts that demand attention from the concerned personnel. And it is a tool used to centralize and interpret massive logs or events that security devices and systems continuously generate.
