Encrypting Data in Transit
- Data encryption at rest is vital as it makes sure that data in motion that clients relay and transfer to MongoDB servers does not get intercepted and potentially hacked.
- This is done by TLS/SSL (Transport Layer Security/Secure Sockets Layer) technology.
Steps to Enable TLS/SSL:
1. Generate SSL/TLS Certificates: OpenSSL – Generate self-signed certificate & key. This below example generates a certificate valid for 365 days:
This example generates a certificate valid for 365 days:
openssl req -newkey rsa:2048 -nodes -keyout mongodb.key -x509 -days 365 -out mongodb.crt
cat mongodb.crt mongodb.key > mongodb.pem
2. Configure MongoDB to Use TLS/SSL:
Edit the mongod.conf configuration file to enable SSL settings:
net:
ssl:
mode: requireSSL
PEMKeyFile: /path/to/mongodb.pem
CAFile: /path/to/mongodb.crt
3. Restart the MongoDB service to apply the changes:
sudo systemctl restart mongod
4. Connect to MongoDB with TLS/SSL:
Use the –tls option in the mongo shell or with MongoDB drivers to establish a secure connection:
mongo --host <hostname> --tls --tlsCAFile /path/to/mongodb.crt --tlsCertificateKeyFile /path/to/mongodb.pem
Encrypt and Protect Data in MongoDB
As technology advances so securing sensitive data is increasingly important for organizations. MongoDB a popular NoSQL database that supports strong encryption to protect data from unauthorized access.
In this article, We will learn about how to encrypt data in MongoDB by including data in transit with TLS/SSL and data at rest also how to rotate encryption keys and manage performance impacts in detail.
