Firewall Rule Recording for Secure Network Relationship Mapping

The patent divides the rule adaptation process into two distinct phases: a recording phase where communication relationships are captured, and a rule generation phase where rules are created from recorded data. This segmentation eliminates the need for continuous complex learning algorithms while maintaining adaptability, as rules are generated on-demand from recorded communication patterns rather than through ongoing automated learning.

The patent performs preliminary recording of communication relationships during normal operation before any rule adaptation is needed. This preliminary action stores the necessary data for future rule generation, eliminating the need for complex real-time learning algorithms when adaptation is required. The recording functionality captures communication patterns in advance, making the subsequent rule generation process simple and transparent.

The patent extracts the data recording functionality as a separate, isolated component that operates independently from the firewall rule enforcement mechanism. The recording phase captures communication relationships without affecting active security rules, and rule generation occurs separately from recorded data. This extraction eliminates security vulnerabilities that would exist during a learning phase, as the recording and rule generation processes are decoupled from the active firewall operation.

The patent introduces recorded communication relationship data as an intermediary between network traffic observation and firewall rule generation. Instead of directly learning from live traffic (which creates security vulnerabilities), the system uses recorded data as a safe intermediary that can be processed offline to generate rules. This intermediary approach maintains security by preventing direct interaction between the learning process and live network traffic.
