CheckPoint 156-590 Exam - Topic 2 Question 13 Discussion

The correct answer is D. Newly created domains. DGA means Domain Generation Algorithm, a technique used by malware to algorithmically create large numbers of domain names for command-and-control communication. Instead of hardcoding one static C2 domain, a bot can generate many possible domains over time, making takedown and static blocking much harder. Check Point's Network Security Software Bundles datasheet states that Check Point AI Deep Learning blocks the latest DNS attacks, including Tunneling and Domain Generation Algorithm/DGA, and specifically blocks connections to the newest generation of malicious domains created via DGA.

This explains why the correct exam option is ''newly created domains.'' Known malicious IP blocking is a reputation and IP intelligence function, but it is not the specific purpose of DGA protection. Infected URLs and infected files are handled by URL reputation, Anti-Virus, Threat Emulation, and related Threat Prevention functions. DGA protection focuses on DNS-layer behavior and suspicious or algorithmically generated domain use, especially when malware attempts to contact rotating or recently generated domains for C2, payload retrieval, or data exfiltration. In operational terms, DGA protection is part of Anti-Bot and Advanced DNS defense, helping detect compromised hosts even when the malware infrastructure changes rapidly.
