How to improve the security of MongoDB

MongoDB provides a series of components to improve data security. Data security is paramount in MongoDB - so it leverages these components to reduce exposure. Here are 10 tips you can use to improve the security of your personal or cloud MongoDB server.

1. Enable auth — Enabling auth is a good security practice even when deploying the MongoDB server on a trusted network. It provides "defense in depth" when your network is attacked. Edit the configuration file to enable auth

1

auth = true

2. Do not expose the production database to the Internet - restricting physical access to the database is security a very important measure. If it is not necessary, do not expose the production environment database to the Internet. If attackers couldn't physically connect to a MongoDB server, data wouldn't be any more secure than it is now. If you deploy your service on Amazon Web Services (AWS), then you should deploy the database in a private subnet of a Virtual Private Cloud (VPC). For more information on this please read the blog post "Deploying MongoDB in a Private Cloud (VPC)".

3. Use a firewall - The use of a firewall can limit which entities are allowed to connect to the MongoDB server. The best approach is to only allow your own application server to access the database. If you are unable to deploy on Amazon Web Services (AWS), you can use the "Security Group" feature to restrict access. If you deploy your service on a provider's host that does not support firewall functionality, you can simply configure the server yourself using "iptables". Please refer to the mongodb documentation to configure iptables for the specific environment you are facing.

4. Use the key file to establish a replication server cluster - specify the shared key file to enable communication between MongoDB instances in the replication cluster. Add the keyfile parameter to the configuration file as follows. The contents of this file must be the same on all machines in the replication cluster.

keyFile = /srv/mongodb/keyfile

5. Disable HTTP status interface - By default Mongodb runs the http interface on port 28017 to provide the "main ” status page. It is recommended not to use this interface in a production environment. It is best to disable this interface. This http interface can be disabled using the "nohttpinterface" configuration setting.

nohttpinterface = true

6. Disable REST interface - It is recommended not to enable MongoDB's REST interface in a production environment. This interface does not support any authentication. This interface is closed by default. If you use the "rest" configuration option to open this interface, you should turn it off on your production system.

1

#rest = false

7. Configure bind_ip- If your system uses multiple network interfaces, then you can use the "bind_ip" option to limit the mongodb server to only Listen on the interface associated with this configuration item. By default mongoDB binds all interfaces.

1

bind_ip = 10.10.0.25,10.10.0.26

8. Enable SSL - If you are not using SSL, then you are between the MongoDB client and the MongoDB server The transmitted data is in clear text and is vulnerable to eavesdropping, tampering and "man-in-the-middle" attacks. If you are connecting to the MongoDB server over an unsecured network like the internet, it is very important to enable SSL.

9. Role-based authentication - MongoDB supports role-based authentication so that you can have fine-grained control over the actions that each user can perform. Use role-based authentication to restrict access to the database so that not all users are administrators. Please refer to the role documentation for more information.

10. Enterprise-level MongoDB and kerberos- Enterprise-level mongodb inherits kerberos authentication. Please refer to the mongodb documentation for more information on this. Username/password based systems are inherently insecure, so use Kerberos based authentication if possible.
