Mastering Network Protocols: An Essential Guide

At the heart of every network, whether it’s the vast expanse of the Internet or the intricate mesh of an office, beat network protocols. Protocols are the way in which two machines communicate with each other, they understand the same language. These invisible rules allow devices to communicate, share data, and work together in harmony. What are Network Protocols? Imagine a world where every…

OTD: 5 May

51 years ago today, the first paper describing Transmission Control Protocol (TCP) was published. TCP is one of the foundational protocols of the Internet, along with IP, UDP, DNS, and HTTP.

Here's a link to a PDF of Cerf and Kahn's original paper, which appeared in the IEEE Transactions on Communications, 5 May 1974:

[kremlin]

it is insane that the modern internet has somehow found a way to make the coolest thing in the world (hacking into computers) lame as fuck by giving every stupid vulnerability a Cool Name and slick SVG vector logo and bootstrap-minimal website and 30 minute slot on prime-time news

"It is with a heavy heart, and great disdain, that I must announce to you, the existence of..."

Bournistoxpide

~ "malloc() delenda est" ~

"It may be the sum total of our place in the history of mankind to admit to our greatest sin, public hosts running craplib-0.9.1g may leak 1kb of internal buffers after 12 hours of fuzzing".

take me back to when you could remote root every single apache webserver by sending it 3 fucking UDP packets. some romanian drug addict would write a worm that infects every routable IP address on the internet and every private host connected to them and ends up owning like half the CIA's/military's/whoever's shit. and the worm would be called some shit like "slapper".

back in the day networking software was what is defined as monolithic: it was all one big blanket of code that handled everything from the data to send to what headers and information add to it before sending it to the Cables(tm)

problem is, get one problem somewhere, you have to unravel all of it to find where the problem is, and the network stops netting and/or working

enter, drumroll please,

iso/osi stacks

the guys over at iso (the organization) came up with this nifty little trick to slice up the Big into many Smalls: 7 layers (or abstraction layers if you are a big nerd)

application: here are the high-end protocols! like http, ftp (file transfer protocol, what were you thinking?) and the dreaded simple mail transfer protocol which i can say after studying it, it is not simple

presentation: applications dont speak internet, so presentation handles (de)codification, (de)encryption and (de)compression however the Protocols see fit

session: most protocols don't have functions or buffers to remember who sent what so session handles keeping connections alive with sessions: little tin cans with a string so the two members of the communication remember each other

transport: this guy is responsible for whether you want to use tcp or udp as a transport protocol (tcp is slower and has data validation for the recipient, udp is faster but fails more often) and chopping up data in tidbits to actually be able to wring them around the net

network: handles ip addresses, routing and telling the other guy everything is okay because that fuckass udp lost me two whole packet fragments

data-link: the oddball of the bunch because it has a dash in its name. and also because it's two sublayers under a trenchcoat

physical: takes whatever the upper layers gobbled up and zip-zaps the cable to send electricity

basically what happens is application concocts the data, hands it to presentatiom and one it is done, it hands it down to session, so on and so forth until physical sends it to the recipient who is going to do the opposite! physical takes the data, gives it to data-link, d-l chews it up a bit, gives it to network until application gets the oh-so-coveted picture of a cat the sender was sending

it's not over yet as those cheeky bastards managed to wedge the stack open with a lego brick remover and stick a little guy called secure sockets layer in to secure the sockets (woah.). he's dead and now we have transport layer security which is that, but better

whevernevr you see an s at the end of a protocol's name, it means one of these two motherfuckers meddled with your data to make it secure and unreadable to the big mean hackers typing dir /s in green letters in the command prompt

Huh
