QuestionQ20
Data Collection and ProcessingEnrage Tech Company hired Enrique, a security analyst, to perform threat-intelligence analysis. During the data-collection process, he used a counterintelligence mechanism in which a recursive DNS server performs interserver DNS communication. When any name server generates a request to the recursive DNS server, the recursive DNS servers log the received responses. The logged data is then replicated and stored in a central database. Using these logs, he analyzed malicious attempts occurring across the DNS infrastructure.
Which cyber counterintelligence (CCI) gathering technique did Enrique use for data collection?
- A Data collection through passive DNS monitoring
- B Data collection through DNS interrogation
- C Data collection through DNS zone transfer
- D Data collection through dynamic DNS (DDNS)
