The description accurately defines a Security Information and Event Management (SIEM) system, which is often referred to as Security Incident and Event Monitoring. A SIEM's core function is to provide a holistic view of an organization's security posture by aggregating log data from diverse sources like servers, network devices, and applications. It then uses correlation engines to analyze these events in real-time, identify potential security threats or incidents based on predefined rules, and generate alerts for security personnel to investigate. This centralized analysis is crucial for detecting complex, multi-stage attacks that might otherwise go unnoticed.

A. network Sniffer: A network sniffer, or packet analyzer, captures and inspects data packets traversing a network. It does not aggregate or correlate event logs from applications or servers.

B. Vulnerability Scanner: A vulnerability scanner is a proactive tool that assesses systems for known weaknesses and misconfigurations. It does not perform real-time monitoring and correlation of event logs.

C. Intrusion prevention Server: An Intrusion Prevention System (IPS) monitors network traffic for malicious activity and can actively block detected threats. It is not primarily a centralized log aggregation and correlation platform.

Section 4.3

Page 4-4: "SIEM software is a centralized application for collecting logs from multiple sources and analyzing them... SIEM software provides features for log analysis

such as event correlation

which is automatically analyzing logs from multiple sources and identifying significant events... SIEM software can also generate alerts to notify administrators of problems." This directly supports the correct answer.

Section 2.1

Page 2-1: Defines an Intrusion Prevention System (IPS) as a system that "can detect and also stop incidents." This highlights its primary role as an active prevention tool

distinct from a SIEM's monitoring and correlation function.

Page 11: Describes the use of SIEMs for "collecting and correlating data from various sources" to detect events

which aligns with the question's description and distinguishes it from other security tools. (Document Number: CMU/SEI-2017-TR-011).
