What Is SIEM and Why Organizations Depend on It

A SIEM (Security Information and Event Management) is the primary visibility and analytics solution used in the SOC (Security Operations Center) operations. The SOC, although primarily relying on human judgment, is supported by the SIEM in terms of the techno-logical capabilities to collect logs, standardize data, and link relevant events while also spotting and marking unusual activities that might signal threats. Today’s SIEMs collect log data from every kind of infrastructure, standardize the data, find connections based on patterns, issue alerts, display live dashboards, create investigation timelines, prepare compliance reports, and keep records for several years.

A SIEM is a security information and event management system that gets data from multiple sources such as firewalls, servers, endpoints, identity systems, cloud services, applications, APIs, and network devices. It monitors and analyzes all these sources to find out and categorize strange activities such as the misuse of privileges, abnormal logins, lateral movement, or data transfer. It is common for organizations to use the SIEM for the detection of weird identity behavior, mojibake coming from the whole user account, finding rare cases of hardware or software problems, making the audit easier, and giving the incident responders the needed timeline of events.
