Slumped Over Keyboard Dead Glossary

Close up of dictionary page

I write about technology a lot. I don’t consider this a beginner tech blog, but I’m also keenly aware that many technology words and acronyms are not well known. I thought it prudent to build a glossary that I can link to when I use these terms so we can all learn together. I’ll try to keep it in alphabetical order; let’s see how that goes. I’ll add to this as life goes on and bump it back to the top whenever I do.

DDoS

Distributed Denial of Service attack. We generally drop the word “attack” today and just refer to a DDoS attack as “a DDoS” or “they were DDoSsed”. It’s pronounce Dee Doss, and not Dee Dee Oh Ess. I will go to the grave saying Dee Doss.

The DDoS of today has its roots in a DoS meaning simply “Denial of Service” attack. The added D today is for the word “Distributed”. When the Internet was small and towney, we saw DoS attacks which were pretty easy to mitigate. A DoS attack is perpetrated by one or two IP addresses and is therefore very easy to mitigate. Just block that IP or two, and the attack is over. Today’s “Distributed” DoS attacks are much harder to mitigate because they come from a wide range of IP addresses. The attack stems from “Distributed” attacking IPs.

The first signifcant DDoS was recorded in 1999 when 227 servers were knocked offline for days. On October 21st 2016, over 10,000,000 IPs were recruited to attack the Dyn DNS servers which made thousands of websites unavailable for a few hours. These times, they are a’ changing.

IoT

Internet of Things. This term is kind of racist. It considers “proper” Internet devices to be computers, routers, and maybe smart phones. Anything else is a “thing” and the proliferation of these Internet-connected “things” have spawned the term Internet of Things.

I’ve heard this pronounced as both Eye Oh Tee and plainly spoken as “Internet of Things”. It works both ways now, mostly because it’s very new. Language is built on concensus and there may be a preferred way to pronounce IoT soon.

The list of things is almost endless now and I am sure it will grow to include every device on the planet within the next decade. Fridges, televisions, lightbulbs, and toasters are all available in wifi connected models for your amusement. The first Internet was populated by people. The current Internet forces us to share the Internet with things.

I’ve written more about the problems with IoT here.
