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

Passive DNS monitoring involves collecting data about DNS queries and responses without actively querying DNS servers, thereby not altering or interfering with DNS traffic. This technique allows analysts to track changes in DNS records and observe patterns that may indicate malicious activity. In the scenario described, Enrique is employing passive DNS monitoring by using a recursive DNS server to log the responses received from name servers, storing these logs in a central database for analysis. This approach is effective for identifying malicious domains, mapping malware campaigns, and understanding threat actors' infrastructure without alerting them to the fact that they are being monitored. This method is distinct from active techniques such as DNS interrogation or zone transfers, which involve sending queries to DNS servers, and dynamic DNS, which refers to the automatic updating of DNS records.

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.

Incorporating a scoring feature in a Threat Intelligence (TI) platform allows SecurityTech Inc. to evaluate and prioritize intelligence sources, threat actors, specific types of attacks, and the organization's digital assets based on their relevance and threat level to the organization. This prioritization helps in allocating resources more effectively, focusing on protecting critical assets and countering the most significant threats. A scoring system can be based on various criteria such as the severity of threats, the value of assets, the reliability of intelligence sources, and the potential impact of threat actors or attack vectors. By quantifying these elements, SecurityTech Inc. can make informed decisions on where to invest its limited funds to enhance its security posture most effectively.
