100-160 Question 232
Select 3During routine network monitoring, a security analyst observes unusual activity in the system logs and decides to use the organization's SIEM platform to further investigate. Which actions can the analyst take using the SIEM to identify potential security incidents?
- A
Correlate log entries from multiple sources to identify patterns of suspicious behavior.
- B
Automatically block malicious IP addresses based on predefined rules.
- C
Search and analyze historical log data to identify trends or anomalies.
- D
Generate alerts in real-time when suspicious activity is detected.
- E
Encrypt traffic to protect data in transit.
Show answer and explanation
Correct answers: A, C, D
Explanation
SIEM platforms play a critical role in cybersecurity by collecting, normalizing, and analyzing log data from multiple sources. This allows analysts to correlate events, search historical data, and generate alerts in real-time to identify potential security incidents. However, SIEMs do not perform active response actions (such as blocking IPs) or handle encryption tasks, which fall under other tools or systems in the security infrastructure.
- A. Correct.
SIEM platforms are designed to correlate log entries from multiple sources, helping analysts identify patterns of suspicious behavior. This is a key function of a SIEM.
- B. Incorrect.
While actions like blocking malicious IP addresses are typically handled by firewalls or SOAR platforms, SIEM platforms are primarily used for monitoring and analysis, not for active response.
- C. Correct.
SIEM platforms allow analysts to search and analyze historical log data to uncover trends or anomalies, which is essential for incident investigation.
- D. Correct.
SIEM solutions are capable of generating real-time alerts by analyzing logs and detecting suspicious activity, enabling rapid response.
- E. Incorrect.
Encrypting traffic is not a function of a SIEM platform. It is typically handled by security protocols or devices like VPNs.
