312-39 (312-39) - EC-Council Exam Questions

You are working as a SOC analyst in a multinational company with multiple data centers and remote offices. Security logs are stored locally at each site, making it difficult to correlate incidents across different locations. Recently, an advanced persistent threat (APT) compromised multiple servers, but due to multiple sources of logs and inconsistent monitoring, the attack was detected only after significant data exfiltration. To improve visibility, streamline log analysis, and enable faster incident response, you need to implement a solution that aggregates logs from all sources into a unified system. Which solution will you implement?

A large financial institution has identified a sophisticated phishing campaign targeting employees, resulting in unauthorized access to sensitive customer data. The organization already uses a SIEM for log aggregation and alerting, alongside an EDR solution for endpoint visibility. Additionally, they have access to XDR for broader threat detection and XSOAR for security orchestration and automation. As a SOC analyst, you’ve been asked to recommend an integration strategy to improve real-time threat correlation, streamline incident response workflows, and maximize the use of existing tools. Which integration would meet these goals?

The SOC analyst at a national cybersecurity agency detected unusual system behavior on critical infrastructure servers. Initial scans flagged potential malware activity. Due to the sophisticated nature of the suspected attack, including registry modifications, process injection, and unauthorized tasks, the case was escalated to the forensic team. The forensic team suspects the malware is designed for stealthy data exfiltration. To assess the compromise, they captured system snapshots before and after suspected infection to identify unauthorized changes and anomalies. Which process are they following by capturing and comparing system snapshots to detect unauthorized changes?

Chloe, a SOC analyst with Jake Tech, is checking Linux systems logs. She is investigating files at /var/log/ wtmp.

What Chloe is looking at?

David Reynolds, a SOC analyst at a healthcare organization, is investigating suspicious login attempts flagged by the SIEM. To mitigate brute-force risk on targeted endpoints, he collaborates with IT to implement an automatic account lockout policy that temporarily disables accounts after multiple failed login attempts. Within the SOC’s eradication strategy, which category of measures does this action align with?
