# Securing Your MongoDB Database

**[Teleport](https://daily.dev/sources/teleport)** · 13 min read · 0 upvotes · 0 comments

## Summary

A comprehensive walkthrough of hardening MongoDB across three layers: network, transport, and database security. Covers firewall configuration with iptables and netsh, SSH/reverse tunneling, IP binding, TLS/SSL setup, FIPS 140-2 compliance, authentication and role-based authorization, auditing, and enterprise-only features like LDAP proxy and encryption at rest. Also touches on MongoDB Atlas-specific security settings such as API key access and advanced security options, before pointing to Teleport Database Access as a way to centralize secure database access.

## Questions this post answers

### How do I enable FIPS 140-2 mode for MongoDB on Linux?

Set up TLS/SSL first, then add FIPSMode: true under the net.tls section of the MongoDB config file (applicable for MongoDB 4.2+, where tls replaces ssl in earlier versions). Start mongod with that config file, then confirm activation by checking the server log for the line 'FIPS 140-2 mode activated'. This method applies to Linux; Windows and macOS require a different tutorial.

### How do I restrict MongoDB network access to specific IP addresses using iptables?

Use iptables to accept inbound connections only from a specified IP address or subnet on the MongoDB port, then drop all other input and output traffic by default. For a single IP, use '-s <ip address>' with '--destination-port <MongoDB port>' and state NEW,ESTABLISHED; for a subnet, append '/24' or the equivalent netmask to the IP address rule.

### How do I set up encryption at rest for MongoDB using a key file?

Generate a base64-encoded key file with 'openssl rand -base64 32 > mongodb-keyfile', restrict its permissions to owner-only with 'chmod 600 mongodb-keyfile', then start mongod with '--enableEncryption --encryptionKeyFile <path to keyfile>'. Confirm success by checking the logs for 'Encryption key manager initialized with key file'. This is an enterprise-only MongoDB feature.
