Comprehensive and Detailed Explanation:
* Understanding the Security Event:
* HOST002 is the only device authorized for internet traffic. However, theSIEM logs show that VM002 is making network connections to web.corp.local.
* This indicatesunauthorized access, which could bea sign of lateral movement or network infection.
* This is ared flagfor potential malware, unauthorized software, or a compromised host.
* Why Option D is Correct:
* Unusual network traffic patternsare often an indicator of acompromised system.
* VM002 should not be communicating externally, but it is.
* This suggests a possiblebreach or malware infectionattempting to communicate with a command-and-control (C2) server.
* Why Other Options Are Incorrect:
* A (Misconfiguration):While a misconfiguration could explain the unauthorized connections, the pattern of activity suggests something more malicious.
* B (Security incident on HOST002):The issue is not with HOST002. The suspicious activity is from VM002.
* C (False positives):The repeated pattern of unauthorized connections makes false positives unlikely.
