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

In the Threat Intelligence Sharing Model, the Public Tier is used when information is of low sensitivity and can be shared widely across communities, industry groups, or the public domain.

This tier is ideal for sharing generalized threat data, advisories, or non-sensitive indicators that do not pose risks to the organization if disclosed.

Why the Other Options Are Incorrect:

Private tier: Used for highly sensitive intelligence shared only within a small internal group or trusted partners.

Targeted tier: Shared with specific, predefined organizations or partners with a need-to-know basis.

Multitier: Involves multiple sharing levels but is not a standard individual tier type.

Conclusion:

Henry should use the Public Tier, suitable for broader sharing of low-sensitivity information.

Final Answer: B. Public tier

Explanation Reference (Based on CTIA Study Concepts):

As per CTIA’s “Threat Intelligence Sharing Framework,” the public tier enables dissemination of low-sensitivity threat intelligence to trusted communities for collaborative defense.

Threat Grid is a threat intelligence and analysis platform that offers advanced capabilities for automatic data collection, filtering, and analysis. It is designed to help organizations convert raw threat data into meaningful, actionable intelligence. By employing advanced analytics and machine learning, Threat Grid can reduce noise from large data sets, helping to eliminate misrepresentations and enhance the quality of the threat intelligence. This makes it an ideal choice for Tim, who is looking to address the challenges of converting raw data into contextual information and managing the noise from massive data collections.

In the Threat Hunting Maturity Model (HMM), Level 2: Procedural represents an organization that has developed a structured but partially manual threat-hunting capability.

At this stage, organizations:

Use threat intelligence from open and closed sources to guide hunts.

Search for anomalies or suspicious activity across their network.

Employ open-source tools and basic scripts for analysis.

Depend on analysts following documented procedures rather than automated systems.

Why the Other Options Are Incorrect:

Level 1: Minimal: Organization relies solely on reactive security measures and lacks dedicated hunting capabilities.

Level 3: Innovative: Introduces automation and advanced analytics to support hunts.

Level 4: Leading: Represents full maturity with proactive, automated, intelligence-driven hunting integrated across all defenses.

Conclusion:

The organization described is operating at Level 2: Procedural in the Threat Hunting Maturity Model.

Final Answer: A. Level 2: Procedural

Explanation Reference (Based on CTIA Study Concepts):

According to CTIA’s framework on “Threat Hunting Maturity Levels,” Level 2 involves intelligence-driven, manual hunting using open-source tools and structured procedures.
