Abstract: Techniques are described that generally relate to centralized vulnerability discovery and management of disparate network-connected devices. A computing device connected to a network determines vulnerabilities for devices connected to the network. The computing device identifies the devices connected to the network and determines vulnerability information for the network-connected devices using one or more remote sources of vulnerability information. For example, the computing device may access websites containing vulnerability or security information, e.g., by performing web searches on a periodic basis, subscribing to one or more web-based feeds of vulnerability information, or the like. The computing device performs a variety of operations (e.g., ranking vulnerabilities, applying patches, sending notifications, or the like) for the network-connected devices based on the vulnerability information.

Abstract: A flow meter comprising a metallic conduit (1) through which, in use, fluid flow takes place, and ultrasonic transducer (4) mounted in a wall of the conduit (1) and operable to sense the presence of fluid in the conduit, the transducer being mounted in the conduit wall in metallic mounting (6) which are sealed in said wall by welding (9).
