00:00 So we've encrypted our MongoDB,
00:03 we've got it hidden behind a firewall and
00:05 listening on a non standard port, let's get into it.
00:08 Here we are connected to our Mongo,
00:10 there is really nothing going on yet, it's just empty,
00:12 we haven't added our data or anything like that, but nonetheless here it is,
00:16 notice there was no user name or password required to get in,
00:19 that's what we're going to fix next.
00:21 So the first thing to do is we're going to run this db.create user command.
00:25 We want to create a user to admin entire database server
00:30 like all of MongoDB not just wherever we happen to be,
00:34 which is called test, not an amazing name.
00:38 So we're going to say use admin and now you can see db is admin
00:44 so we can show collections, see what's here
00:46 and it's basically empty, but now we can run these db commands
00:50 focused on creating users against admin which means kind of global.
00:54 So we're going to run this command here, paste it so I don't get it wrong
00:59 because these roles have to be just so, it's very touchy,
01:02 go with this for the db admin, that's probably fine,
01:07 or mongodb admin, you can take your pick
01:10 and the password is probably little wimpy, let's try to fix that.
01:14
01:18 Let's go over here and run pt python and import uuid, okay,
01:24 and then let's do something like this, print
01:28
01:37 we'll call uuid that uuid4, call that, there we go,
01:43 what do you think is that a decent password?
01:47 I would say so, that's going to definitely slow down some dictionary attacks.
01:51 Now over here, we got to delete this,
01:55 sadly you can't paste over a selection in MacOS,
01:58 alright, so we're going to run this user, this password
02:01 and now we have to specify the roles
02:04 we could create like multiple users
02:06 that have certain restricted access to different databases
02:10 and that's probably not a bad idea, but for this example
02:12 we're just going to say this thing can admin read databases,
02:17 admin any databases or clusters
02:19 by the way just because you are an admin for a database
02:22 does not mean you can read and write to it
02:25 you could just create users and things like that, so you need them all.
02:28 Let's try this, boom, successfully created.
02:32 Now, did magic happen when we did this?
02:34 Let me copy this real quick, if I exit and I go over here
02:42 and I try to connect without any authentication,
02:44 no, nothing happened; why, if we come over here and we check out our config,
02:52 down here at the security, this puupy is wide open
02:57 so we need to go down and say authorization is enabled;
03:05 now, if we do that and we restart MongoDB,
03:07 so service mongo d restart, probably a good idea to ask for status,
03:12 also not happy, again, what have we done, let's have a look.
03:18 I think it might help if I spelled this right,
03:20 not very forgiving these computers are they,
03:23 all right, everything is running that's all good,
03:26 and if we try to connect to it again, now it's going to come over here and say
03:31 hello you are connected right, db.version for example, like this,
03:37 right so we're connected to it, we can sort of interact with it
03:42 but watch this, show dbs, failure you cannot show dbs,
03:47 in fact, you can't do anything other than basically log in.
03:51 So I can come over and say db, I say this use admin db.auth
03:58 and I could set the username and password, so I could say
04:04 user is this, password is whatever we want to put here,
04:10 you have to forgive me if I don't want to type that again, copy and paste that,
04:14 pwd rather not password, so we could log in this way, as you'll see
04:22 now I can say show dbs, use test and so on, show collection,
04:30 so I am basically authenticated at this point, right,
04:34 so I can log in this way and do this, but you probably don't want to do this,
04:38 you probably don't want to do it that way,
04:40 instead you probably want to say user is this,
04:44 it says pwd, I think it might be, is this
04:49
04:52 oh one more thing, I forgot, so we have the username and the password
04:56 but we also have to add the authentication database being admin
04:59 there we go, okay, notice our warning about running without authentication is gone
05:08 and I can now show dbs straight away, I don't have to go do this like
05:12 switch to admin, do the auth and so on.
05:15 So this is really handy for our scripts here that we're going to use later.
