00:01 You've learned almost everything you need to know about MongoDB 00:04 to work with it, to make it fast, to access it from things like MongoEngine. 00:07 The last thing is to actually put it into production, 00:11 to use MongoDB in production to set up our applications, 00:14 to talk to a secured version of MongoDB, all of those things. 00:18 So we're going to focus on two main areas, 00:21 one deploy MongoDB for production servers, two, doing that safely. 00:25 So far, what we've been doing is we've been running our web app, 00:30 or script, our little test app, whatever it is that we're going to be building, 00:34 a little thing we even playing with, and that's the blue thing here, 00:37 and we've been running it and talking to MongoDB on our local machine, 00:40 probably our laptop, and we've been just on the local loop back, 00:44 127.0.0.1, talking to MongoDB, and I have gone on and on 00:49 about how you must not listen on another ip address on your local dev machine, 00:55 take that thing to a coffee shop or worse, to like a big hotel 00:59 where there's a tech conference, god forbid, black hat or something going on 01:04 and that thing will be in some serious, serious trouble right away. 01:08 By the way, did you know on your Mac that the firewall is off by default? 01:12 That's right off by default, that's crazy, but it is, so just another thing to consider, 01:18 layers and layers and layers, but assuming we're only listening 01:21 on local loopback we're pretty safe like this, 01:24 but we have been running without encryption and running without authentication, 01:29 MongoDB gave us a little warning when we connected 01:32 but you have to connect, you have to care, if you connect with code 01:35 and not with a shell, there is no warning it just works, 01:38 we're going to set up an entirely different thing 01:41 we're going to have a set of web front ends, fake web front ends, 01:44 we're not really going to write a website, but what would stand in for our website 01:49 and we're going to have our production MongoDb server, 01:51 and these things are going to talk to each other over 01:55 at least the file computing data center connection, 01:57 potentially farther than that, so we're going to have to open this thing up 02:01 and that means we need to add things like encryption, 02:04 we need to add authentication, firewall sorts of rules and things like that. 02:07 That's what we're going to talk about in this chapter. 02:10 This is a bit of a chore, right, this is not the default 02:14 unfortunately this is not the falling into the pit of success type of thing, 02:18 you have to work to get this set up correctly 02:21 so let me just give you some very recent warnings 02:24 this is not to tell you not to use MongoDB, 02:27 I use MongoDB for my production stuff, I love MongoDB 02:29 but you must use it carefully, it's like a sharp knife. 02:33 What I am about to show you is not meant to dissuade you in any way 02:36 but just to make sure you really have this burnt your mind 02:39 that you have to be careful when you're deploying stuff to production with MongoDB. 02:43 That said, check this out—  here are some recent headlines 02:47 and you want your company and your data to be nowhere near them, 02:51 MongoDB databases are being hacked for ransom using ransomware 02:56 notice this is 2017, here's a little example, look at this, 03:00 show dbs, please read, use please read, show collections, 03:04 please read me do a little find on it and you get 03:08 your database is been hacked and encrypted 03:10 you have to send a bitcoin here to get it back 03:13 and chances are they will probably just throw away your data 03:15 and they'll take your bitcoin and yeah, good job, 03:17 okay, so here's another one, how about this 03:20 massive ransomware attack takes out 27 thousand MongoDB servers 03:24 terabytes and terabytes of data, the petabytes of data we're lost to the world, 03:28 so these are all not good things, right, you've lost your data 03:31 here is one more, two million recordings of families 03:34 imperiled by cloud connected toys crappy MongoDB 03:38 you don't want that anywhere near your business, 03:41 so this is a little bear thing here, that with a light on it 03:43 it connects to the internet and it connects to a service 03:47 and then the parent and the kid can like talk to each other 03:50 over the internet through the bear, 03:52 that was basically all that data in that exchange was done 03:55 entirely on a wide open MongoDB database with no account at all, 03:59 just hey here's the port, connect to it, go have fun. 04:03 All right, so the problem here is that MongoDB lets you listen 04:07 on the wide open internet without a usnername and password 04:10 and without encryption and that's the default. 04:13 What we're going to do it is we're going to add all those things 04:16 but you just wanted to be really clear 04:19 like this is not an optional step, we really need to do this 04:22 unless you're running this, like say you're running a website 04:24 and the database server is running the same machine as the web server 04:28 and it just talks over a local host 04:30 any other scenario use to be extremely careful 04:32 and we're going to go through all the steps necessary to get this working just right.
