# Data security #

In IBM watsonx, data security mechanisms, such as encryption, protect sensitive customer and corporate data, both in transit and at rest\. A secure , and other mechanisms protect your valuable corporate data\. A secure IBM Cloud Object Storage instance stores data assets from projects, catalogs, and deployment spaces\.

## Configuring Cloud Object Storage ##

IBM Cloud Object Storage provides storage for projects, catalogs, and deployment spaces\. You are required to associate an IBM Cloud Object Storage instance when you create projects, catalogs, or deployment spaces to store files for assets, such as uploaded data files or notebook files\. The Lite plan instance is free to use for storage capacity up to 25 GB per month\.

You can also access data sources in an IBM Cloud Object Storage instance\. To access data IBM Cloud Object Storage, you create an IBM Cloud Object Storage connection when you want to connect to data stored in IBM Cloud Object Storage\. An IBM Cloud Object Storage connection has a different purpose from the IBM Cloud Object Storage instance that you associate with a project, deployment space, or catalog\.

The IBM Cloud Identity and Access Management (IAM) service securely authenticates users and controls access to IBM Cloud Object Storage\. See [IBM Cloud docs: Getting started with IAM](https://cloud.ibm.com/docs/cloud-object-storage?topic=cloud-object-storage-iam) for instructions on setting up access control for Cloud Object Storage on IBM Cloud\.

See [IBM Cloud docs: Getting started with IBM Cloud Object Storage](https://cloud.ibm.com/docs/cloud-object-storage?topic=cloud-object-storage-getting-started-cloud-object-storage)

## Controlling access with service credentials ##

Cloud Object Storage credentials consist of a service credential and a Service ID\. Policies are assigned to Service IDs to control access\. The credentials are used to create a secure connection to the Cloud Object Storage instance, with access control as determined by the policy\.

For more information, see [Controlling access to Cloud Object Storage buckets](https://dataplatform.cloud.ibm.com/docs/content/wsj/manage-data/cos_buckets.html)

## Encrypting at rest data ##

By default, at rest data is encrypted with randomly generated keys that are managed by IBM\. If the default keys are sufficient protection for your data, no additional action is needed\. To provide extra protection for at rest data, you can create and manage your own keys with IBM® Key Protect for IBM Cloud™\. Key Protect is a full\-service encryption solution that allows data to be secured and stored in IBM Cloud Object Storage\.

To encrypt your Cloud Object Storage instance with your own key, create an instance of the IBM Key Project service from the IBM Cloud catalog\. Not all Watson Studio plans support customer\-generated encryption keys\.

## Encrypting in motion data ##

Data is encrypted when transmitted by IBM on any public networks and within the Cloud Service's private data center network\. Encryption methods such as HTTPS, SSL, and TLS are used to protect data in motion\.

## Backups ##

To avoid loss of important data, create and properly store backups\. You can use IBM Cloud Backup to securely back up your data between IBM Cloud servers in one or more IBM Cloud data centers\. See [IBM Cloud docs: Getting started with IBM Cloud Backup](https://cloud.ibm.com/docs/Backup?topic=Backup-getting-started)
