350-201 Exam Dumps : Performing CyberOps Using Core Security Technologies (CBRCOR)

Creating an automation script for blocking URLs on the firewall when the rule is triggered will improve the effectiveness of the process by reducing the time between the detection of a request to a malicious URL and the blocking action. This proactive approach ensures that the URLs are blocked immediately, minimizing the window of opportunity for the threat to cause harm

The packet capture shown in the exhibit is indicative of DNS tunneling. This conclusion is drawn from the observation of the packets’ consistent size and frequency, which are directed to a specific destination IP address. Such a pattern is characteristic of DNS tunneling, where data is encapsulated within DNS queries and responses. This method is often used to bypass security controls or for data exfiltration, as it can blend with regular DNS traffic, making detection more challenging.

DNS tunneling can be used for legitimate purposes, such as when an organization’s remote workers need to access internal networks. However, it is also a technique commonly exploited by attackers to smuggle data out of a network or to communicate with command and control servers while evading detection.
