Abstract: A method for monitoring a file system within a distributed network is provided. From a local hosting environment having a native scanning tool, creation of a new data store within the network is detected. Responsive to detecting creation of the new data store, it is determined whether the new data store is physically located within a foreign hosting environment that is communicatively coupled to the local hosting environment through a non-private network. If the new data store is physically located within the foreign hosting environment, an agent of the native scanning tool is created within the foreign hosting environment and the agent is applied to the new data store within the foreign hosting environment to obtain sensitivity information for the new data store. The sensitivity information for the new data store is received and recorded in the local hosting environment.

Abstract: A method for designing a phased-array antenna embedded into stacked high impedance surfaces (HIS) structure is proposed. The stacked HIS structure comprises a plurality of HIS cell, which has two plate layers with adjustable height of the lower layer. Each HIS cell has a corresponding LC tank structure. Under a given height (HIS cell volume), the overall capacitance increases when the height of the lower layer plate increases. By adjusting the height of the lower layer plate, a variable capacitance of the corresponding LC tank can be achieved to allow lower operation frequencies of the phased-array antenna and to realize the benefit of HIS in band of interest. In addition, different design conditions can be achieved for the phased-array antenna.

Abstract: A NAT system is identified as operating in conjunction with a specific IP address, in response to a threshold number of different authenticated computing devices making requests to the web service from the specific IP address during a given time period. The total number of computing devices operating from behind the identified NAT system is estimated, based on how many separate authenticated computing devices make requests to the web service from the IP address during the period of time. When a NAT system is identified, one or more additional action(s) are taken to manage the processing of traffic originating from the specific IP address, taking into account that multiple computing devices are operating behind the identified NAT system. An example action is rate limiting.
