MongoDB for Developers with Python Transcripts
Chapter: Deploying MongoDB in production (and playing it safe)
Lecture: The MongoDB deployment checklist
0:00 Let's go through the MongoDB security checklist.
0:03 Now, most of these come from MongoDB,
0:05 but also from me personally, from my experience running the server.
0:09 I've run professional commercial websites
0:12 using MongoDB for many years, 5 or 6 years
0:14 and we've never had any problems, but you have to follow the rules.
0:17 Some of the rules include things like limit network exposure,
0:20 so this is always a good idea for databases
0:23 or anything else that listens on the internet,
0:26 if something doesn't need to talk to it, don't allow it to have an open connection.
0:30 Enable access control, that means add users and require them to authenticate,
0:36 this should really be the default, if I were king of MongoDB,
0:41 and I'm not, but if I were a king of MongoDB,
0:43 I would make a decree, a new rule that says
0:46 MongoDB is not allowed to listen on anything other than local host,
0:50 unless it has access control enabled, period.
0:54 That's not the way it works right now though,
0:56 by default you can just say listen on 0000
0:59 and it will, even if that's wide open, so that can be problematic,
1:04 so we're going to change that,
1:07 encrypt the communication, so certainly what goes on the wire
1:09 should be ssl style encrypted,
1:12 but there is an option to encrypt the data at rest,
1:15 I think you have to get the enterprise version of MongoDB which is the paid version
1:20 this is not something I worry too much about
1:22 but if it's something that you were about,
1:24 you can encrypt the data at rest using the wire tiger engine.
1:27 You can audit system activity, this is easy enough
1:32 turn on what's called a caped collection and turn on auditing
1:36 so it will keep some standard amount
1:39 obviously set up logging, all those types of things.
1:42 Back up, obviously you want to back up your data
1:46 this is production data, so back up, back up, back up, back up,
1:49 set up some way to back up and we'll see that there's two options
1:52 we can run a tool called Mongo dump which will just take a complete backup
1:56 and for a certain size of data, that could be pretty large actually
2:00 but for certain size that works fine,
2:03 at some point if you truly are working
2:05 with tremendous amounts of data that doesn't work so well
2:07 so there's various ways to set up replicas
2:09 that are like delayed or right on time, things like this
2:13 but back up, back up, back up, an important thing to do.
2:16 So you can find all the details on how to do this here
2:20 at mongodb.com/manual/administration/security-checklist
2:23 now you're welcome to go over there and check that out
2:25 and I encourage you to do so,
2:28 but we're going to go through each of the yellow steps here
2:30 we're not going to talk about auditing, but everything else pretty much
2:32 and encryption and rest, we're also not going to do that,
2:35 everything else we're going to do as part of this chapter.
