Question

Which of the following sources does a SIEM system typically pull data from?

1) Personnel emails
2) Network intrusion detection alerts
3) System event logs
4) Encrypted personal data

Answer 1

SIEM systems pull data from sources such as network intrusion detection alerts and system event logs, which are vital for security monitoring and incident response. Option 2,3 are correct.

Step-by-step explanation:

A Security Information and Event Management (SIEM) system typically pulls data from various sources within an organization's IT infrastructure to enable security analysts to detect, analyze, and respond to cybersecurity incidents. Among the data sources for a SIEM system are:

Network intrusion detection alerts

System event logs

Network intrusion detection systems (NIDS) are designed to detect suspicious activities or policy violations on a network, and these alerts are critical for SIEM systems in real-time security monitoring. System event logs, which record the activities of system hardware, software, and users, also provide a wealth of actionable intelligence for SIEM systems.

SIEM systems do not typically pull data from sources that contain sensitive personal information, like personnel emails or encrypted personal data, without proper authorization and relevance to security monitoring tasks.
