Information Technology Specialist (ITS) Cybersecurity Practice Exam

Which three standards allow for the exchange of cyber threat intelligence in a machine-readable format?

1. TAXII, STIX, CyboX

2. SOC, SIEM, IDS

3. OSINT, IOCs, TTPs

4. NIST, ISO, CEPA

The correct answer is: TAXII, STIX, CyboX

The selection of TAXII, STIX, and CyboX as the three standards that facilitate the exchange of cyber threat intelligence in a machine-readable format is grounded in their specific roles within the cybersecurity ecosystem. TAXII (Trusted Automated eXchange of Indicator Information) is a protocol designed for the automated exchange of cyber threat intelligence. It allows organizations to share information about threats and indicators of compromise in a structured way, which can be easily parsed and processed by machines. STIX (Structured Threat Information Expression) provides a language for describing cyber threat intelligence in a structured and machine-readable format. It defines how to convey various attributes of cybersecurity incidents, such as tactics, techniques, procedures, and context around the threat data, making it more actionable for security teams. CyboX, while less commonly referenced than the other two, aligns with the goal of defining a standardized format for representing cybersecurity information. It builds on the principles of STIX and serves as an additional framework that supports the communication of threat data. Together, TAXII and STIX provide a robust framework for sharing cyber threat intelligence that enhances the ability of organizations to collaborate and respond to threats efficiently. This contrasts with the other options, which either refer to processes, frameworks, or terms that are
