Abstract: A sensor monitoring system includes a plurality of image capture devices. Each image capture device includes one or more sensors to detect image data representing an environment about the image capture device, communications circuitry to receive sensor data from a sensor device and remote sensor data including at least one of a second image of the sensor or second position data regarding the sensor device, and processing circuitry to validate the sensor device based on the sensor data, determine first position data regarding the sensor device based on at least one of the first network connection or the remote sensor data, determine that the sensor device is in an image capture range based on the first position data, retrieve one or more images of the sensor device, and generate an alert based on the first position data.

Abstract: A firewall uses a variety of techniques to obtain a useful domain name from a network request, that is, a domain name that facilitates the accurate enforcement of domain-based security rules for network traffic at the firewall. If the network request includes an Internet Protocol (IP) address instead of the domain name, the firewall may begin with a reverse domain name lookup. If this technique fails to adequately resolve the domain name, then the firewall may attempt a hypertext transfer protocol (HTTP) GET request to the IP address and investigate the header for useful domain name information. The firewall may also or instead initiate a secure connection to the IP address and analyze a certificate returned from the destination for the presence of domain name information. These measures can produce one or more domain names that can be collectively analyzed to select a suitable domain name for the application of a domain-based security rule or policy by the firewall.
