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

In the trust model described, where trust between two organizations depends on the degree and quality of evidence provided by the first organization, the model in use is 'Validated Trust.' This model relies on the validation of evidence or credentials presented by one party to another to establish trust. The validation process assesses the credibility, reliability, and relevance of the information shared, forming the basis of the trust relationship between the sharing partners. This approach is common in threat intelligence sharing where the accuracy and reliability of shared information are critical.

The exchange of attack techniques, compromised systems, and immediate defensive actions represents Tactical Threat Intelligence sharing.

Tactical Threat Intelligence focuses on adversary Tactics, Techniques, and Procedures (TTPs) and helps defenders understand and counter ongoing attacks in real time.

Why the Other Options Are Incorrect:

B. Operational: Focuses on broader attack campaigns and contextual analysis.

C. Strategic: Provides high-level, long-term insights for executives.

D. Technical: Concerns low-level indicators like IPs and file hashes, not methodologies or immediate actions.

Conclusion:

The collaboration involves Tactical Threat Intelligence, which centers on sharing actionable TTPs and response techniques.

Final Answer: A. Sharing tactical threat intelligence

Explanation Reference (Based on CTIA Study Concepts):

CTIA defines tactical threat intelligence as intelligence describing attacker behaviors and techniques that can be acted upon immediately by defenders.

In the scenario described, where attackers have penetrated the network and are staging data for exfiltration, Jim should focus on monitoring network traffic for signs of malicious file transfers, implement file integrity monitoring, and scrutinize event logs. This approach is crucial for detecting unusual activity that could indicate data staging, such as large volumes of data being moved to uncommon locations, sudden changes in file integrity, or suspicious entries in event logs. Early detection of these indicators can help in identifying the staging activity before the data is exfiltrated from the network.

The phase described involves defining and setting up what intelligence needs to be collected before the actual collection process begins. This aligns with the Intelligence Requirements phase of the threat intelligence lifecycle.

Intelligence Requirements define what information is needed and why it is needed to support decision-making or intelligence production. These requirements guide the collection and analysis processes by specifying the goals and priorities of intelligence gathering.

Kira’s focus should be on determining the exact intelligence needs that will later drive the production of actionable insights.

Why the Other Options Are Incorrect:

A. Production requirements: Concerned with how intelligence reports and outputs will be formatted and disseminated after analysis, not what data should be collected.

C. Business requirements: Focus on organizational goals or project objectives, not specific intelligence needs.

D. Collection requirements: Define how and from where to gather data, but are based on intelligence requirements, which come first.

Conclusion:

Kira should define Intelligence Requirements, which determine what must be collected to fulfill intelligence production needs.

Final Answer: B. Intelligence requirements

Explanation Reference (Based on CTIA Study Concepts):

In the CTIA threat intelligence lifecycle, defining intelligence requirements is the first stage and establishes the foundation for effective intelligence collection and production.

Information Sharing and Analysis Centers (ISACs) are nonprofit organizations established to facilitate secure sharing of threat intelligence among companies within a specific industry sector.

ISACs provide:

A trusted platform for sharing cyber threat indicators.

Secure mechanisms for communication and collaboration.

Analytical services that enhance shared threat data for participating members.

Each ISAC is industry-specific (for example, Financial Services ISAC, Energy ISAC) and provides members with reports, advisories, and data analytics to strengthen collective defense.

Why the Other Options Are Incorrect:

Trading partners: Share intelligence directly between organizations with established business relationships.

Informal contacts: Represent ad hoc, trust-based sharing without a formal structure.

Commercial vendors: Offer paid threat intelligence feeds or services, not nonprofit community-based sharing.

Conclusion:

Tech Knights Inc. should use an Information Sharing and Analysis Center (ISAC) to share intelligence securely and collaboratively.

Final Answer: B. Information Sharing and Analysis Centers (ISACs)

Explanation Reference (Based on CTIA Study Concepts):

According to CTIA’s section on “Information Sharing Models,” ISACs are nonprofit entities that promote collaboration and data exchange for cyber threat intelligence within industry sectors.
