Section 6.8 SIEM
The diagram depicts a central rectangular component labeled "[S]ecurity and [I]nformation [E]vent [M]anagement," with the initial letters S, I, E, M bracketed to emphasize the acronym SIEM. This box represents the SIEM system.
Arrows point from various external sources towards this central SIEM box, symbolizing the collection of log and event data. These sources, labeled around the SIEM, are: From the top: "Firewalls" and "Servers." From the left: "Workstations" and "Routers." From the right: "Switches" and "Proxies." From the bottom: "IPS" (Intrusion Prevention System) and "DMARC" (Domain-based Message Authentication, Reporting, and Conformance).
This visualization highlights the function of a SIEM in centralizing and processing security-related information from diverse components within an IT infrastructure.
Security and Information Event management is a system for real-time monitoring of security information. Typically a SIEM system presents a dashboard showing events and has the ability to generate reports or create tickets. It may be separate device, software on an internal device, or even a third party service. Some examples of popular SIEMs are QRadar, Splunk, and Azure Sentinel.
