(ISC)2 Certified in Cybersecurity Practice Exam

What type of security solution collects information from diverse sources for analysis?

1. Antivirus Software

2. Firewall

3. Security Incident and Event Management (SIEM)

4. Intrusion Detection System

The correct answer is: Security Incident and Event Management (SIEM)

The correct choice is Security Incident and Event Management (SIEM). SIEM systems are designed to aggregate and analyze data from diverse sources, such as servers, network devices, domain controllers, and applications. By collecting logs and security-related documentation from these various sources, SIEM solutions provide a comprehensive view of the security posture of an organization. The primary purpose of a SIEM is to facilitate real-time monitoring and alerting of potential security incidents, helping organizations quickly respond to threats. They utilize correlation rules to look for patterns or anomalies across the collected data, enabling security teams to identify and mitigate threats more effectively. In contrast, antivirus software primarily focuses on detecting and removing malicious software from individual endpoints, making it limited in scope compared to a SIEM. Firewalls are essential for controlling incoming and outgoing network traffic based on predetermined security rules but do not aggregate and analyze data across multiple sources. An Intrusion Detection System (IDS) monitors network traffic for suspicious activity and potential intrusions but lacks the comprehensive analysis and logging capabilities that SIEM systems provide. Thus, SIEM stands out as the most relevant solution for collecting and analyzing data from a variety of sources for a holistic view of security events.
