CompTIA Updated CAS-005 Exam Questions and Answers by sulaiman

D. STIX (Structured Threat Information eXpression): STIX is a standardized language for representing threat information in a structured and machine-readable format. It facilitates the sharing ofthreat intelligence by ensuring that data is consistent and can be easily understood by all parties involved.

E. TAXII (Trusted Automated eXchange of Indicator Information): TAXII is a transport mechanism that enables the sharing of cyber threat information over a secure and trusted network. It works in conjunction with STIX to automate the exchange of threat intelligence among organizations.

Other options:

A. CWPP (Cloud Workload Protection Platform): This focuses on securing cloud workloads and is not directly related to threat intelligence sharing.

B. YARA: YARA is used for malware research and identifying patterns in files, but it is not a platform for sharing threat intelligence.

C. ATT&CK: This is a knowledge base of adversary tactics andtechniques but does not facilitate the sharing of threat intelligence data.

F. JTAG: JTAG is a standard for testing and debugging integrated circuits, not related to threat intelligence.

Anacceptable use policy (AUP)defines what is considered appropriate use of corporate email and prevents unnecessary emails to personal accounts. This helps in reducing false DLP alerts while maintaining compliance.

Quarantining emails (A)is unnecessary since the content was not flagged as sensitive.

Encryption (C)secures emails but does not address overuse.

Phishing awareness training (D)is unrelated to policy enforcement for outgoing emails.

Implementing security and quality checks in a CI/CD pipeline ensures that:

Container images are scanned for vulnerabilities beforedeployment.

Version control is enforced, preventing unauthorized changes.

Hashes validate image integrity.

Other options:

A (Configuring ACLs on mesh networks) improves access control but does not ensure scanning.

C (Audits on container images) detect changes but do not enforce best practices.

D (Pulling from a vendor repository) does not ensure vulnerability scanning.

HMAC (Hash-based Message Authentication Code)ensures the integrity and authentication of API requests without exposing static or hard-coded private keys. It uses a secret key and a hash function, preventing replay attacks and tampering. VPNs secure the transport layer, MFA protects user accounts (not API-to-database communications), and DSA is a signature algorithm but does not address hard-coding risk directly.
