About this talk
A lighthearted arts-and-crafts project demonstrating network documentation basics using pasta, glue, and paper. Counselor Nick walks through building a visual network diagram with cloud, firewall, routers, DMZ, switches, and end users, then adds a narrative layer by illustrating a penetration test scenario with a compromised web application and malware deployment.

howdy hoe campers it's counselor nick here from the speaker ops cabin before we get rolling with our arts and crafts project today a quick reminder for our pen test campers camp stay at home is on a septic system so please make sure you're only deploying authorized payloads in the toilets nobody needs a denial of service what we're going to be making today are macaroni network diagrams because we all need better network documentation so what you're going to need is some glue some pasta shapes some paper i'm using dark paper because the av counselors were telling me something about exposure and white balance and lastly you're going to need a pair of tweezers for fine placement

so now that we've got all of our equipment in place we're going to start off with the first thing that every single network diagram needs which is a big old picture of the cloud so i'm going to rub some glue up in the corner here i'm going to take a little handful of rice and just sort of press that on and move these off for a second and we're gonna give this page a shake to get all that excess on beautiful best cloud you've ever seen right terrific okay now so for lines into our network uh i pre-broke some of the spaghetti right here which is gonna just be great for general you know traces and

communications lines and things like that okay put a little little line right there excellent so at the perimeter of our network we're going to want some maybe kind of protection so what i've got here is a little piece of bow tie pasta that looks an awful lot like a firewall to me so we're just going to slam this right here excellent now heading on into our network we're going to want some kind of central router so after another line i figure maybe a couple pieces of macaroni make a nice looking router

beautiful no maybe uh just on the initial interior of our network here maybe we've got a nice looking dmz with uh some sort of external maybe an external web application so there's our our outside service and our dmz now let's build a couple of network segments right because nobody wants a flat network uh you know i hear the campers over at uh crystal lake they had a flat network now they're dealing with all kinds of hackers or slashers or something along those lines grab some more macaroni maybe these are switches maybe they're rotors i don't know

excellent okay so there's sort of our second layer um now we'll have maybe a couple more roots going off these and now we can finally add our end users so maybe we got some end users over here all right so it's gonna go

and we're just gonna take these and users and stick them on the end of these little network segments

excellent so we have our basic network diagram maybe it's a little boring uh right maybe we want to make a little bit more dynamic maybe we're trying to illustrate something so how about recently uh our organization realized it had some new compliance requirements and we had to go ahead and contract out a penetration testing team and they managed to find maybe a bug in our external web application maybe you know they sent some phishing emails to some of our users and we're able to deploy maybe a little bit of malware over here that's a little bit nicer right now we have a little bit of a story it's a little more dynamic we're we're telling something

uh and then there's our piece of completed network documentation if the uh network diagram isn't really your thing maybe you're more into electronics you could maybe try something like a uh you know a uh schematic diagram also done in pasta maybe you need a reference for your favorite boost converter or something along those lines so anyways uh that's our project for today have a great day everybody
