300-215 Question 227
Select 2A cybersecurity analyst is reviewing threat intelligence data received from a trusted source. The data contains details about a newly identified malware campaign, structured in a machine-readable format that allows automated sharing between multiple organizations. The analyst needs to integrate this data into the organization's security tools for further analysis and response. Which of the following formats and protocols are most likely being used to share this threat intelligence?
- A
STIX (Structured Threat Information Expression)
- B
TAXII (Trusted Automated Exchange of Indicator Information)
- C
JSON (JavaScript Object Notation)
- D
CSV (Comma-Separated Values)
- E
YARA (Yet Another Recursive Algorithm)
Show answer and explanation
Correct answers: A, B
Explanation
STIX and TAXII are key standards for sharing and analyzing threat intelligence. STIX provides a structured format for representing threat intelligence, while TAXII serves as the protocol for sharing this information between systems. Together, they enable organizations to exchange actionable threat intelligence in a machine-readable and interoperable manner, making them the ideal choice for the scenario described in the question.
- A. Correct.
STIX is a structured language specifically designed for representing threat intelligence, enabling detailed and standardized sharing of threat data.
- B. Correct.
TAXII is a transport protocol specifically developed for the automated exchange of threat intelligence, often used in conjunction with STIX to share structured threat data.
- C. Incorrect.
JSON is a general-purpose data format but is not specifically designed for threat intelligence sharing. While STIX uses JSON as its underlying format, it is not a threat intelligence standard by itself.
- D. Incorrect.
CSV is a simple data format for tabular data and lacks the structure and semantics needed for representing or sharing threat intelligence in a standardized manner.
- E. Incorrect.
YARA is a tool for identifying and classifying malware but is not used for sharing or structuring threat intelligence in a standardized way.
