Now that I have your attention, how can we possibly audit a network and find all the juicy details about the devices upon it, without having high level credentials to talk to those devices? Well, it’s a bit of a mistruth. Or a caveat. Or whatever you want to call it. We definitely can do this, but for devices such as routers, printers and switches you will need a minimal set (read only, minimum access level) of SNMP credentials.
