How to dynamically generate Cassandra database users.

The Infisical Cassandra dynamic secret allows you to generate Cassandra database credentials on demand based on configured role.

Prerequisite

Infisical requires a Cassandra user in your instance with the necessary permissions. This user will facilitate the creation of new accounts as needed. Ensure the user possesses privileges for creating, dropping, and granting permissions to roles for it to be able to create dynamic secrets.

In your Cassandra configuration file cassandra.yaml, make sure you have the following settings:

authenticator: PasswordAuthenticator
authorizer: CassandraAuthorizer

The above configuration allows user creation and granting permissions.

Set up Dynamic Secrets with Cassandra

1. Open Secret Overview Dashboard

   Open the Secret Overview dashboard and select the environment in which you would like to add a dynamic secret.

2. Click on the 'Add Dynamic Secret' button

   

3. Select Cassandra

   

4. Provide the inputs for dynamic secret parameters

   Secret Name · string · required

   Name by which you want the secret to be referenced

   Default TTL · string · required

   Default time-to-live for a generated secret (it is possible to modify this value when a secret is generate)

   Max TTL · string · required

   Maximum time-to-live for a generated secret

   Host · string · required

   Cassandra Host. You can specify multiple Cassandra hosts by separating them with commas.

   Port · number · required

   Cassandra port

   User · string · required

   Username that will be used to create dynamic secrets

   Password · string · required

   Password that will be used to create dynamic secrets

   Local Data Center · string · required

   Specify the local data center in Cassandra that you want to use. This choice should align with your Cassandra cluster setup.

   Keyspace · string

   Keyspace name where you want to create dynamic secrets. This ensures that the user is limited to that keyspace.

   CA(SSL) · string

   A CA may be required if your cassandra requires it for incoming connections.

   

5. (Optional) Modify CQL Statements

   If you want to provide specific privileges for the generated dynamic credentials, you can modify the CQL statement to your needs. This is useful if you want to only give access to a specific key-space(s).

   

6. Click 'Submit'

   After submitting the form, you will see a dynamic secret created in the dashboard.

   If this step fails, you may have to add the CA certficate.

   

7. Generate dynamic secrets

   Once you’ve successfully configured the dynamic secret, you’re ready to generate on-demand credentials. To do this, simply click on the ‘Generate’ button which appears when hovering over the dynamic secret item. Alternatively, you can initiate the creation of a new lease by selecting ‘New Lease’ from the dynamic secret lease list section.

   

   When generating these secrets, it’s important to specify a Time-to-Live (TTL) duration. This will dictate how long the credentials are valid for.

   

   Ensure that the TTL for the lease fall within the maximum TTL defined when configuring the dynamic secret in step 4.

   Once you click the Submit button, a new secret lease will be generated and the credentials for it will be shown to you.

   

Audit or Revoke Leases

Once you have created one or more leases, you will be able to access them by clicking on the respective dynamic secret item on the dashboard. This will allow you see the lease details and delete the lease ahead of its expiration time.

Renew Leases

To extend the life of the generated dynamic secret lease past its initial time to live, simply click on the Renew as illustrated below.

Lease renewals cannot exceed the maximum TTL set when configuring the dynamic secret
