312-85 Dumps With Exact Questions and Answers

Karry ' s method of collecting data, which involves no active engagement with participants and is purely based on analysis and observation of activities within the organization, is known as passive data collection. This method is characterized by the non-intrusive monitoring of data and events, allowing analysts to gather intelligence without alerting potential adversaries or disrupting ongoing processes. Passive data collection is essential for maintaining operational security and obtaining an unaltered view of system and network activities.

Fast-Flux DNS is a technique used by attackers to hide phishing and malware distribution sites behind an ever-changing network of compromised hosts acting as proxies. It involves rapidly changing the association of domain names with multiple IP addresses, making the detection and shutdown of malicious sites more difficult. This technique contrasts with DNS zone transfers, which involve the replication of DNS data across DNS servers, or Dynamic DNS, which typically involves the automatic updating of DNS records for dynamic IP addresses, but not necessarily for malicious purposes. DNS interrogation involves querying DNS servers to retrieve information about domain names, but it does not involve hiding malicious content. Fast-Flux DNS specifically refers to the rapid changes in DNS records to obfuscate the source of the malicious activity, aligning with the scenario described.

The method described involves analyzing activities, timeframes, dependencies, and milestones to understand project flow and relationships. This is known as Critical Path Analysis (CPA) .

Critical Path Analysis helps identify the sequence of crucial tasks that determine the overall project duration. In the context of threat intelligence, it assists analysts in mapping adversary activities or operational timelines to determine key steps and dependencies in attack campaigns.

Why the Other Options Are Incorrect:

B. Timeline analysis: Focuses on chronological sequencing of events, not dependency or duration analysis.

C. Cone of plausibility: Used for scenario modeling and forecasting possible outcomes.

D. Analogy analysis: Compares new situations to historical cases, not time-dependent task mapping.

Conclusion:

Steve applied Critical Path Analysis to determine activity dependencies and durations.

Final Answer: A. Critical path analysis

Explanation Reference (Based on CTIA Study Concepts):

CTIA defines CPA as a structured approach for mapping and analyzing sequences of dependent activities or events.
