Abstract: Systems and methods to manage multiple vulnerability scanners distributed across one or more networks using a distributed security management system, herein called a Lightning Console. By distributing multiple scanners across a network, the work load of each scanner may be reduced to significantly reduce the impact on the network routing and switching infrastructure. In addition, scanners may be placed directly behind firewalls for more thorough scanning. Further, scanners may be placed closer to their scanned networks. By placing vulnerability scanners closer, the actual scanning traffic does not cross the core network switch and routing fabric, thereby avoiding potential network outages due to scanning activity. In addition, the closer distance of the scanners to the scanned targets speeds scan times by reducing the distance that the packets must traverse.

Abstract: Systems and methods to passively scan a network are disclosed herein. The passive scanner sniffs a plurality of packets traveling across the network. The passive scanner analyzes information from the sniffed packets to build a topology of network devices and services that are active on the network. In addition, the passive scanner analyzes the information to detect vulnerabilities in network devices and services. Finally, the passive scanner prepares a report containing the detected vulnerabilities and the topology when it observes a minimum number of sessions. Because the passive scanner operates passively, it may operate continuously without burdening the network. Similarly, it also may obtain information regarding client-side and server side vulnerabilities.
