Analyzing network traffic based on naming information
A recently granted patent (Publication Number: US11916943B2) outlines a method for monitoring network traffic and detecting potential compromises in devices within a network. The method involves accessing name translation traffic from an intermediate translation device acting as a local cache, extracting name and address information, storing this data, and associating subsequent network traffic with the stored information. By matching address information in the network traffic with the stored data, the method can determine if a device has been compromised and classify the device based on the extracted information. Additionally, the patent describes determining indications of intrusion and session classifications based on the name information obtained.
Furthermore, the patent details a system and a non-transitory computer-readable medium that implement the method described. The system includes a processing device that accesses domain name system (DNS) responses and IP addresses, matches them with incoming network packets, and determines security characteristics of devices based on the extracted information. The system can also access time-related data associated with the DNS responses and classify devices based on device classification or session classification. The non-transitory computer-readable medium contains instructions for executing the method, including monitoring network traffic, matching addresses, and determining compromise indications based on the extracted name information. Overall, the patent provides a comprehensive approach to monitoring network traffic, detecting compromises, and classifying devices within a network based on name translation traffic.
