A security feature that allows data encryption for data kept on disc in an OpenSearch cluster is known as “OpenSearch encryption at rest.” At Bobcares, with our Server Management Service, we can handle your issues.

OpenSearch Encryption at Rest | An Introduction

The term “OpenSearch encryption at rest” describes a security feature that allows data stored on a disc in an OpenSearch cluster to be encrypted. An open-source distributed search and analytics engine called OpenSearch (formerly called Open Distro for Elasticsearch) is a fork of Elasticsearch.

Secure data kept in a database or search engine must be encrypted when at rest to prevent unwanted access in the event of physical loss or unauthorised access to the underlying storage. Data that is encrypted at rest is kept on a disc in an encrypted state, and accessing and reading the data requires decryption.

OpenSearch Encryption at Rest | Working

1. OpenSearch encrypts data while it’s at rest using industry-standard encryption techniques. The highly secure 256-bit AES (Advanced Encryption Standard) technique is one that is frequently utilised.

2. Data must be encrypted and decrypted using encryption keys. A key management system is used by OpenSearch to safely handle encryption keys. The encryption keys are only accessible to authorised entities thanks to the key management system.

3. When information is written on a disc, it is encrypted, and when it is read, it is decrypted. OpenSearch encrypts data during inter-node connection using SSL/TLS (Secure Sockets Layer/Transport Layer Security) to guarantee secure communication between nodes in the cluster.

4. Since the encrypted data is kept on the disc in a secure location, it is more difficult for malevolent parties or unauthorised individuals to access it directly.

5. Resting-state encryption is merely one security layer. Strong authentication and access control features are also offered by OpenSearch to guarantee that the data is accessible to only authorised users and apps.

Setting up the necessary parameters in the OpenSearch configuration files is required to enable encryption at rest in OpenSearch. Depending on the deployment environment and the version of OpenSearch we are using, the precise steps could change.
