Abstract: A device, system and method for provisioning firewall engines is provided. A device, in an observation mode: implements, for a given zone, an application and a firewall engine in an observation mode by: implementing predefined firewall rules that define allowed network traffic and/or denied network traffic for the application; maintaining a log of network traffic events that meet or do not meet the predefined firewall rules, the log including source and destination network identifiers for the network traffic events; grouping the network traffic events into groups based on the source and destination network identifiers; generating new firewall rules based on the groups; and accepting or denying respective new firewall rules. The device, after the observation mode is implemented, switches the application and the firewall engine to a maintain mode by: stopping implementing the predefined firewall rules; and implementing accepted new firewall rules for the application.

Abstract: An apparatus for inflating a deflated member from a source of compressed air includes a flexible tube member having a first end and a second end; a first coupling at the first end of the tube for connecting to the deflated member; and a second coupling, different from the first coupling, at the second end of the tube for connecting to the source of compressed air; wherein the first coupling includes a check valve for preventing flow from the deflated member to the tube, whereby the first coupling can be connected to the deflated member and the second coupling can be sequentially connected to a plurality of sources of compressed air.
