Tips to Improve MongoDB Security





Security is not a default feature of MongoDB. Putting MongoDB into production without configuring it for authentication will lead to trouble. Your server can be accessed by others without requiring them to log in or authenticate in any way. 





Database security is easy to implement and can be accomplished in a few steps.

In this tutorial is to walk you through some important Tips to Improve your MongoDB server Security,





A MongoDB database that hasn’t been configured can be hacked very easily. Cyber criminals can discover databases that are unprotected without requiring user authentication and steal information from them using online search engines. In order to prevent data breaches, MongoDB should be properly configured and a few key security practices should be applied. 





Let’s look at some best practices you can use to stop hackers in their tracks.





1. Enable authentication




The practice of enabling authentication is good security practice for MongoDB servers even if you deploy them in a trusted network. In case of a network compromise, it will provide the best defense.



Access to a database must be restricted and client identities must be verified using user authentication. Authenticating users can be done using MongoDB’s native service or an external tool such as Active Directory. By providing a username and password in the command line and specifying an authentication database, you are able to authenticate users with MongoDB.





Authentication is supported in two ways by MongoDB’s base version:





1. In SCRAM (Salted Challenge Response Authentication Mechanism), the system checks a user’s credentials against the username and password entered by the user.




2. X.509 Certificate Authentication, An authentication method that uses certificates instead of passwords to authenticate clients to a server.





There are also two other methods of authentication available to MongoDB Enterprise users:




1. LDAP proxy authentication (Lightweight Directory Access Protocol) 




2. Kerberos authentication





2. Use firewalls 


Your MongoDB server can be restricted through firewalls from being accessed by other entities. It is recommended that you only provide database access to your application servers. Access can be restricted using ‘Security groups’ if your site is hosted on AWS. In the case of an ISP that doesn’t support firewalls, you can use iptables to configure your own firewall.




No worry, with VPSie you can create the firewall and configure it yourself.





3. Backup your data 




You will be able to access your data even if there is a cyberattack or system failure if you regularly back up your data. Then, no matter what happens – someone encrypts your data and demands a ransom, or a natural disaster causes your business to burn in the fire, you will have access to your most recent backup, allowing you to restore it to its pre-attack state.





You can back up MongoDB in three different ways:




1. Filesystem snapshots: To take a snapshot of the file system, use tools like LinuxLVM. Backup large amounts of data in a reliable manner.





2. MongoDB Management Service (MMS): MongoDB opslog data is continuously sent to MMS for backup using this service. Snapshots are taken every six hours with a 24-hour retention period.





3. mongodump: This utility creates a snapshot of an entire database or query result, and is included with MongoDB. Great for deployments of small databases, but can struggle with larger ones.





4. Enable SSL 


You should use SSL to protect your data because, by default, data between your Mongo client and Mongo server is unencrypted, making the connection susceptible to eavesdropping, tampering and “men in the middle” attacks. The point is especially important if you are accessing your MongoDB server via an unsecure network like the Internet.





5. Configure bind_ip 




In systems with more than one network interface, you can use “bind_ip” to limit your MongoDB server to listen only to the relevant interfaces. All interfaces are bound by default in MongoDB:





7. Monitor your Network 




A performance monitoring program is a great way to detect signs of a cyberattack and detect when your resources are not performing as well as they should. If your database has a performance problem, database monitoring software can notify you through alerts and alert you to take action.




8. Don’t use the default settings





MongoDB has all the security settings you need to protect yourself against attackers. All you need to do is configure them. If you use a database with the default settings, your data is at risk of being breached. Following a few best practices and configuring MongoDB correctly can help to prevent a lot of problems.





There are many other way’s to consider besides those we discussed, so we have only touched on some of the most important ones.






That’s it!
