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

The described activity involves pretending to be a legitimate or authorized person in order to gather sensitive information. This social engineering technique is known as Impersonation.

Impersonation is a form of deception in which the attacker pretends to be someone else — such as an employee, contractor, or service technician — to gain access to restricted information or areas. In this method, the attacker often relies on trust, authority, or familiarity to manipulate others into revealing confidential data.

In the scenario, the analyst obtained information by observing terminals, searching desks, and examining bins while pretending to be a trusted individual. This fits the definition of impersonation rather than other social engineering methods.

Why the Other Options Are Incorrect:

Shoulder surfing: Involves directly observing someone’s screen or keyboard to capture credentials or data, not pretending to be someone else.

Piggybacking: Refers to physically following an authorized person into a restricted area without proper authentication.

Dumpster diving: Involves searching discarded items, such as trash or recycle bins, to find confidential information, without human interaction or pretense.

Conclusion:

The analyst used Impersonation to pose as an authorized person and collect sensitive data.

Final Answer: A. Impersonation

Explanation Reference (Based on CTIA Study Concepts):

From the CTIA study materials under “Social Engineering and Threat Collection Techniques,” impersonation is identified as a key human-based technique for gathering information during reconnaissance.

Centralized storage architecture refers to a system where data is stored in a localized system, server, or storage hardware. This type of storage is capable of holding a limited amount of data in its database and is locally available for data usage. Centralized storage is commonly used in smaller organizations or specific departments within larger organizations where the volume of data is manageable and does not require the scalability offered by distributed or cloud storage solutions. Centralized storage systems simplify data management and access but might present challenges in terms of scalability and data recovery.

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.
