312-85 Exam Dumps : Certified Threat Intelligence Analyst (CTIA)

Passive DNS monitoring involves collecting data about DNS queries and responses without actively querying DNS servers, thereby not altering or interfering with DNS traffic. This technique allows analysts to track changes in DNS records and observe patterns that may indicate malicious activity. In the scenario described, Enrique is employing passive DNS monitoring by using a recursive DNS server to log the responses received from name servers, storing these logs in a central database for analysis. This approach is effective for identifying malicious domains, mapping malware campaigns, and understanding threat actors' infrastructure without alerting them to the fact that they are being monitored. This method is distinct from active techniques such as DNS interrogation or zone transfers, which involve sending queries to DNS servers, and dynamic DNS, which refers to the automatic updating of DNS records.

A model where all threat data is collected, analyzed, and distributed through a single central hub defines a Centralized Exchange Architecture.

In this architecture:

All participants send their data to a central system.

The central hub processes, correlates, and redistributes intelligence.

It ensures uniform analysis, consistency, and efficient management.

Why the Other Options Are Incorrect:

A. Decentralized: Each participant shares data directly with others without a central hub.

B. Federated: Each organization maintains its own data but participates in shared analysis through agreed protocols.

C. Hybrid: Combines elements of centralized and decentralized systems for flexibility.

Conclusion:

The described setup represents a Centralized Exchange Architecture.

Final Answer: D. Centralized exchange architecture

Explanation Reference (Based on CTIA Study Concepts):

CTIA classifies centralized architectures as systems that collect and distribute threat data through a single authoritative node.

FININT (Financial Intelligence) refers to the collection, processing, and analysis of financial transaction data to identify suspicious or illicit activities such as fraud, money laundering, terrorist financing, or financial crimes.

In this scenario, the analyst is investigating unusual financial transaction patterns, which is exactly the purpose of financial intelligence.

Key Features of FININT:

Focuses on financial data sources, including transaction records, wire transfers, and account statements.

Helps detect illicit financial flows or abnormal transaction behaviors.

Used by banks, financial institutions, and government agencies to identify and prevent financial crimes.

Often shared with intelligence agencies and regulatory bodies to support counter-fraud and anti-money laundering operations.

Why the Other Options Are Incorrect:

A. OSINT:Refers to publicly available information such as websites, news, or social media. It is not specific to financial transaction data.

B. CHIS:Refers to human intelligence sources obtained through personal or covert interaction, not financial data analysis.

C. TECHINT:Refers to intelligence gathered from technical sources such as sensors or electronic systems, not financial records.

Conclusion:

The correct intelligence type used to analyze suspicious financial transactions is FININT (Financial Intelligence).

Final Answer: D. FININT

Explanation Reference (Based on CTIA Study Concepts):

As per CTIA threat intelligence classifications, FININT involves collecting and analyzing financial data to detect and mitigate fraudulent or criminal activities.
