(ISC)2 Certified in Cybersecurity Practice Exam

What does a security information management (SIM) system do?

1. It manages encryption keys securely

2. It is used to analyze and report on security events and incidents

3. It logs user access attempts

4. It prioritizes software updates

The correct answer is: It is used to analyze and report on security events and incidents

A security information management (SIM) system primarily focuses on the analysis and reporting of security events and incidents within an organization's IT environment. It aggregates log data and security events from various sources, such as firewalls, intrusion detection systems, and other security appliances. By centralizing this information, a SIM system helps security professionals in identifying patterns, monitoring for anomalies, and responding to incidents effectively. Through the analysis capabilities, security teams can generate reports that provide insights into security threats, compliance status, and system vulnerabilities. This information is crucial for maintaining a proactive security posture and ensuring that appropriate measures are taken in response to detected risks. Other choices, while relevant to security practices, do not accurately describe the core functionality of a SIM system. For example, managing encryption keys is typically handled by key management solutions rather than a SIM. Logging user access attempts is more aligned with identity and access management solutions or log management systems. Prioritizing software updates is generally a function of patch management systems that specifically deal with software vulnerabilities rather than a SIM, which is more focused on security event analysis.
