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

ABC cyber-security company, which has implemented automation for tasks such as data enrichment and indicator aggregation and has joined various communities to increase knowledge about emerging threats, is demonstrating characteristics of a Level 3 maturity in the threat intelligence maturity model. At this level, organizations have a formal Cyber Threat Intelligence (CTI) program in place, with processes and tools implemented to collect, analyze, and integrate threat intelligence into their security operations. Although they may still be reactive in detecting and preventing threats, the existence of structured CTI capabilities indicates a more developed stage of threat intelligence maturity.References:

Fast-Flux DNS is a technique used by attackers to hide phishing and malware distribution sites behind an ever-changing network of compromised hosts acting as proxies. It involves rapidly changing the association of domain names with multiple IP addresses, making the detection and shutdown of malicious sites more difficult. This technique contrasts with DNS zone transfers, which involve the replication of DNS data across DNS servers, or Dynamic DNS, which typically involves the automatic updating of DNS records for dynamic IP addresses, but not necessarily for malicious purposes. DNS interrogation involves querying DNS servers to retrieve information about domain names, but it does not involve hiding malicious content. Fast-Flux DNS specifically refers to the rapid changes in DNS records to obfuscate the source of the malicious activity, aligning with the scenario described.References:
