A recently granted patent (Publication Number: US11930031B2) discloses a method for passively scanning a network using an endpoint passive scanner deployed on an endpoint device. The method involves sniffing network traffic to and from the endpoint device, detecting information that aids in discovering network assets and vulnerabilities, and performing a vulnerability scan of the endpoint device. The endpoint passive scanner is integrated as a passive scan library linked to an endpoint agent on the device, running when called by the agent. The method includes discovering assets, identifying vulnerabilities, providing reports to a vulnerability manager external to the device, correlating assets and vulnerabilities with the vulnerability scan, and building a network topology based on the reports.

Furthermore, the patent details the process of obtaining information from network traffic, discovering assets, and identifying vulnerabilities based on the obtained data. The method involves correlating discovered assets and vulnerabilities with the vulnerability scan, building a network topology by a vulnerability manager external to the device, and providing detailed reports to aid in network security. The endpoint device is configured to passively scan the network by sniffing network traffic and detecting relevant information, ultimately enhancing network security by identifying vulnerabilities and assets. The integration of the endpoint passive scanner as a passive scan library linked to the endpoint agent ensures efficient scanning and reporting processes for network security management.
