Abstract: In some embodiments, a hybrid approach is provided for discovering devices on a network, assessing if the devices are vulnerable to security threats and malicious attacks, remediating the devices that are vulnerable, detecting security threats and malicious attacks on the network, and responding to such threats and attacks. In some implementations, a hybrid site manager for the network passively scans the network, obtains information about a network device, and actively transmits a probe to the network device based on the obtained information. In some embodiments, the hybrid site manager actively sends a probe over the network to a network device, receives a response to the probe, and modifies how it passively scans the network based on the response to the probe.

Abstract: A method for identifying devices on a network, comprising: determining, by a discovery application, a prioritized discovery plan including a plurality of tiers of requests, each of the tiers specifying one or more probes for targeting specific types of devices. For each of the tiers in the prioritized discovery plan: the method further comprises causing, by the discovery application, one or more of the probes specified for the tier to transmit targeted requests to a set of active addresses on the network. Upon receiving responses from at least a subset of the one or more addresses, the method comprises identifying, by the discovery application, one or more devices connected to the network based on the responses to the targeted requests. The method further comprises removing, by the discovery application, addresses corresponding to the identified one or more devices from the set of active addresses on the network.

Abstract: The invention supports the study of operations and provides a large data store of surface and terminal area operations, as well as means of analyzing and understanding that data. It fuses multiple surveillance and flight data sources to provide analysis functionality for both airborne and surface based flights. This provides a wider range of data to make intelligent categorization and derived data analysis decisions. The invention implements custom logic for matching flights to corresponding data messages by maintaining its own key mappings between data tables during import so that keys are unique to an installation and do not require sequences. This provides the ability to export datasets through the PostgreSQL dump utility and then import it into an existing database (using the PostgreSQL restore utility) without creating overlapping, duplicate or conflicting keys. XML based format is used and import and export features is that allow users to share these custom queries.
