A small business is looking to implement a basic Security Information and Event Management (SIEM) solution. They have limited resources but need to centralize logs for compliance and basic threat detection. Which of the following is a primary benefit of using a SIEM for this scenario?
- ADeep packet inspection of all network traffic.
- BAutomated patching of vulnerabilities on endpoints.
- CReal-time correlation of security events from disparate sources.
- DEndpoint Detection and Response (EDR) capabilities.
Show answer & explanationAnswer & explanation
Correct answer: C. Real-time correlation of security events from disparate sources.
A primary benefit of SIEM is its ability to centralize and correlate security events from various sources (firewalls, servers, applications) to provide a unified view and detect complex threats that individual logs might miss. This directly addresses the need for centralized logs and basic threat detection.
Why the other options are wrong
- A. Deep packet inspection is typically a function of firewalls or intrusion prevention systems (IPS), not a primary SIEM feature.
- B. Automated patching is a function of patch management systems, not SIEM.
- D. EDR focuses on endpoint visibility and response, while SIEM has a broader scope across the IT environment.
SIEM Core Function
A Security Information and Event Management (SIEM) system's core function is to collect, aggregate, and analyze log data and security events from various sources across an organization's IT infrastructure.
- Centralizes security data.
- Enables real-time monitoring and correlation.
- Aids in compliance reporting and incident detection.
