1) Is citrix based on linux technology? Reason I ask is our 3rd party IT produced a list of public facing infrastructure, and for the citrix access gateway they've declared it as "a linux virtual appliance"?
2) Also, is there anyway to see what version of a citrix access gateway is running? Do citrix release secrutiy updates for their products? If so how can we see if we are the latest supported versions? Any tools that can assist in this area?
