Abstract: The system and method for correlating network identities and addresses described herein may include a log correlation engine distributed on a network that identifies relationships between certain network identities and Internet Protocol (IP) and Ethernet addresses in the network. In particular, the log correlation engine may analyze various event logs that describe activity in a network to learn relationships between network identities and network addresses and generate alerts in response to discovering changes in the learned relationships. For example, the log correlation engine may identify authentication events described in the logs to map network identities to IP addresses, and may further analyze the logs to map the IP addresses to Ethernet addresses. Thus, the log correlation engine may discover new and changed relationships between the network identities, the IP addresses, and the Ethernet addresses.

Abstract: The system and method for enabling remote registry service security audits described herein may include scanning a network to construct a model or topology of the network. In particular, the model or topology of the network may include characteristics describing various devices in the network, which may be analyzed to determine whether a remote registry service has been enabled on the devices. For example, the security audits may include performing one or more credentialed policy scans to enable the remote registry service for certain devices that have disabled the remote registry service, auditing the devices in response to enabling the remote registry service, and then disabling the remote registry service on the devices. Thus, the system and method described herein may enable remotely scanning information contained in device registries during a security audit without exposing the device registries to malicious activity.

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.
