Which of the following actions represents the most effective immediate response to mitigate the potential impact and preserve evidence?

Accepted Answer

Isolate the critical database server from the network and block the newly registered domain at the perimeter firewall.

Question 28

Anya, a seasoned SOC analyst, is investigating a critical security incident involving a sophisticated ransomware strain that has bypassed initial perimeter defenses. The malware demonstrates highly adaptive characteristics, including polymorphic code that constantly changes its file signature and robust anti-analysis mechanisms designed to detect and thwart standard forensic tools and sandboxing environments. Anya\'s initial containment efforts are complicated by the malware\'s ability to spread laterally through the network via zero-day exploits. Her team\'s incident response playbooks are proving insufficient due to the novel nature of the threat, requiring a significant adjustment in their analytical approach.

Which of the following strategic pivots would best enable Anya to effectively analyze and contain this evasive ransomware variant, given the limitations of signature-based detection and traditional static analysis?

Accepted Answer

Prioritize memory forensics and dynamic behavioral analysis in a hardened, isolated environment to observe the malware's execution flow and identify emergent patterns of malicious activity.

Question 29

Anya, a cybersecurity analyst, is tasked with responding to a sophisticated zero-day exploit that has just been discovered targeting her company\'s primary e-commerce platform.
