@Ren:
From your extensive knowledge of the history of mega-corporations you know that public institutions like the Veteran's Hospital in Tacoma are practically a joke compared to their privately owned counterparts that have an almost inexhaustible pool of resources. Ever since the Shiawase decision at the beginning of the century and even before that, public institutions began to be eroded by business friendly policy makers to the point where by 2075, the fragmented governments of this day and age basically keep places like Tacoma Vet's Hospital running for the sole purpose of maintaining a semblance of legitimacy. No penny is pinched when it comes to providing the boys and girls of the UCAS army with state of the art guns, armor and training, but once they take too much damage to be useful on the battlefield, they're pretty much just seen as a liability. Places like TVH serve as the proverbial carpet under which they're swept. Care just barely good enough so SINless parents don't riot, and plenty bad enough so that it doesn't cost UCAS too much to keep open.
You turn your attention way from the little black spider icon and look up into the night sky following the data trail your deck has highlighted for you. In the blink of an eye you fly up and instantly stand in front of a giant rotating red cross symbol with the UCAS armed forces logo stamped on it and the Tacoma Veteran's Hospital in big shiny letters in front. A typical Doc Wagon hospital would have a non-stop stream of persona's entering and exiting as doctors, nurses and other staff log-on or log-off from the systems even between shift changes. In the 1.2 seconds that you've been watching the host, you've seen maybe 2 icons go in or out. As you probe how sophisticated the security of the host is you are surprised to see the whole analysis summary clock it in as a rating 7 host. That's rather high for a place that's supposedly falling apart. Maybe it's the military affiliation, but you doubt UCAS would invest heavily in costly matrix security and then skimp on cyber-eyes, pacemakers and building repairs. You even remember about a year ago an embarrassing story broke of a particularly nasty awakened mold infestation they had to deal with. Had to evacuate the whole place and it cost millions to clean out and then move everyone back in.
All of the firewall subroutines average out to be defending the system at about a whopping rating 10.
OOC: you don't need to spot hosts with Matrix perception and commcodes don't seem to really exist anymore in 5e, you can just identify icons as if they were people I guess. Hosts aren't on any grid, they're just fragments of the matrix. So that gives you 3 more pieces of information you can ask for.
@Storm & Zach:
With the illusion in place you both sit patiently while Stake lies motionless. By the fluttering of his eyes you know he's definitely quite active decking away at whatever it is. Zach also pays close attention to the flyspy's sensor feed AR window as it starts climbing through the little hole in the tin roof.
