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.

By assessing the Threat Intelligence (TI) program through a comparison of project results with the original objectives, and by ensuring that all expected deliverables have been produced to an acceptable quality level, Joe is conducting a gap analysis. Gap analysis involves identifying the difference between the current state and the desired state or objectives, in this case, the outcomes of the TI program versus its intended goals as outlined in the project charter. This process allows for the assessment of what was successful, what fell short, and where improvements can be made, thereby evaluating the program's overall effectiveness and identifying areas for future enhancement.

When attackers or analysts search job postings on online job portals, they often uncover technical details inadvertently shared by organizations.

Job listings frequently mention:

Hardware and software used (e.g., “experience with Cisco firewalls, Windows Server 2019”).

Network details and tools (e.g., “knowledge of LAN/WAN, AWS, Azure”).

Security technologies (e.g., “SIEM tools like Splunk or QRadar”).

This information can help analysts identify the technological footprint of the company, which is valuable during threat profiling or reconnaissance.

Why the Other Options Are Incorrect:

B. Top-level domains and subdomains: Obtained through DNS enumeration tools, not job sites.

C. Open ports and services: Found through active scanning tools like Nmap, not via job postings.

Conclusion:

Flora can obtain hardware, software, and network-related information from online job listings.

Final Answer: A. Hardware and software information, network-related information, and technologies used by the company

Explanation Reference (Based on CTIA Study Concepts):

CTIA recognizes online job sites as OSINT sources that can reveal technical environment details about organizations.
