this clothesline in Long Island New York\h was the U.S government's first ever system\h\h
for transmitting top secret data it was the\h Revolutionary War and the Americans needed\h\h
a way to get information from New York City to\h George Washington's headquarters in Morristown\h\h
New Jersey without the British intercepting it\h so they wrote down 763 words assigned each a\h\h
number between 1 and 763 and bada bing bada boom\h you've got the worst Cipher in military history\h\h
but whatever people's brains were too riddled with\h dysentery or something and somehow this seemed to\h\h
do the trick these encrypted letters would travel\h along this route from New York City to here in\h\h
Setauket where they would be stashed in one of\h five locations a local woman and a strong would\h\h
then hang up a black Petticoat on her clothesline\h to signal to nearby ships that the letter was\h\h
ready to be picked up with between one and five\h white handkerchiefs to indicate which location\h\h
the letter was hidden in from there the letter\h would then be secretly picked up and make the\h\h
rest of the journey to Morristown unfortunately\h we're no longer allowed to distribute information\h\h
about British warships and the US Department\h of Defense has since updated its methods for\h\h
securely transmitting government secrets today the\h US uses three different networks each designed for\h\h
different levels of classification to send\h sensitive data across the globe here's how\h\h
they work the first and least secure of the three\h is called necromant the non-classified Internet\h\h
Protocol router Network basically nevernet is\h a private interconnected network of government\h\h
computers that is attached through secure gateways\h to the rest of the internet technically you could\h\h
access it using the same connection you're using\h to watch this video but you probably wouldn't get\h\h
very far think of it like a gated community they\h might be connected to the wider system of roads\h\h
but if you go there without the right credentials\h you'll wind up in prison or shot you can't access\h\h
never Nets unless you're part of a government\h agency or approved government contractor that's\h\h
giving you access but it's used pretty widely and\h isn't monitored too closely none of the data on\h\h
nippernet is technically classified it's just\h stuff that the government doesn't want floating\h\h
around in public data like tax records internal\h schedules or these photos of Obama paddle boarding\h\h
for data that's actually classified and not\h just too titillating for public consumption\h\h
the Department of Defense uses a network\h called sipper net or with a secure Internet\h\h
Protocol router Network this is the network that\h deals with any information that's been labeled\h\h
confidential or secret the first two levels of DOD\h classification examples of confidential or secret\h\h
information might be say lists of War reserves\h scientific studies relevant to military Tech\h\h
information about enemy weaknesses this video of\h two U.S Apache helicopters firing on civilians\h\h
that got leaked when supernet was compromised in\h 2010. oh whoops how did that get in there oh well\h\h
you get the idea this network unlike neighbor\h Nets is completely disconnected from the rest\h\h
of the internet and only connects government\h computers to one another it does this with\h\h
a fairly standard method of data transfer called\h packet switching where your messages split up into\h\h
pieces all of which take different routes along\h the network before reaching their destination\h\h
now keeping all the classified data contained\h within this network separate and unsullied by\h\h
the evils of public internet is more complicated\h than just isolating the network itself you also\h\h
need to isolate every single device that has\h ever touched the network if you connect your\h\h
computer to supernet it is permanently considered\h classified at the secret level that means it can\h\h
only be used or stored in locations that have been\h approved by the government to have secret level\h\h
data in plain sight anything that's ever been\h plugged into that computer is now also considered\h\h
classified technically if you plug this USB rock\h into to separinet the Department of Defense would\h\h
be bound by federal law to protect its secrecy\h forever but despite all those headaches cybernet\h\h
is not even the government's most secure network\h now that would be the joint worldwide intelligence\h\h
Communication System the network used to transmit\h top secret data for some reason the government has\h\h
been a little vague about exactly how this\h network works but on a technical level it\h\h
functioned pretty similarly to say Burnet data\h is transmitted by a satellite across a closed\h\h
network of government computers with the ability\h to denote which packets of data are most sensitive\h\h
those then take the fastest and most secure route\h through the network so they spend the least amount\h\h
of time flying through space where anyone could\h NAB them with a really tiny butterfly net any data\h\h
on jwics can only be stored or accessed in highly\h specialized rooms called sensitive compartmented\h\h
information facilities there are quite a few of\h these around the globe that can be as small as a\h\h
closet or as large as an office building but some\h notable examples would be the Situation Room in\h\h
the White House or the cabin of Air Force One in\h order to keep the top secret data contained within\h\h
jwics both top and secret these rooms have some\h very very specific technical requirements that\h\h
you would think would be kept Under Wraps but are\h actually all written out in excruciating detail in\h\h
this seemingly not very top secret document since\h publicizing this is apparently not considered a\h\h
national security risk here's exactly how these\h facilities are constructed standard seif walls are\h\h
composed of 5 8 inch gypsum wall board buffered\h by three and a half inches of sound attenuated\h\h
material and sealed with acoustic sealant\h to ensure the secrets don't slip through the\h\h
cracks each perimeter wall is installed with radio\h frequency protection as well as optional speakers\h\h
that play vibrations louder than any conversations\h being held inside the room what doors need to\h\h
follow these specifications steel doors need to\h follow these specifications windows are a bad\h\h
idea monitors must be faced away from the doorways\h and no one from any country we've recently pissed\h\h
off is allowed to build any of this so that's how\h you keep top secret secret or you could just use a\h\h
clothesline because nobody cracked that either\h but hey you know what's not a highly sensitive\h\h
government secret the amount of absurdly Good\h original content that's been piling up on nebula\h\h
recently if you're out of the loop nebula is the\h create your own educational streaming service that\h\h
I started with my friends it's become this amazing\h opportunity for us to create the videos that we've\h\h
always wanted to create but couldn't because\h the constraints of YouTube the team and I have\h\h
already produced four on-site documentaries for\h nebula as well as a trivia show a bizarre piece of\h\h
self-referential fiction and a travel show where\h I break laws across the country but that's just\h\h
us navya also has channels like City beautiful\h producing a whole series on the greatest cities\h\h
on Earth or real life lore taking a deep dive on\h Modern conflicts around the world that's not to\h\h
mention all the content that you can watch early\h on nebula before your favorite creators bring\h\h
those videos to YouTube if you've been following\h our other channel just like the game you can watch\h\h
those videos a week in advance on nebula and say\h a full episode ahead of everyone watching on here\h\h
