Buying DSC

If you use DSC through the console, you will be billed on a yearly/monthly basis, which is prepaid. If you use DSC by APIs, including data masking and watermark APIs, you pay for what you used. DSC provides the standard and professional editions, and the database and OBS expansion packages. You can choose the base plan that fits your site's needs, then add relevant expansion packages as needed.

Prerequisites

You have added the obtained account to the user group that has been assigned with the DSC FullAccess permission. For details, see Using IAM Roles or Policies to Grant Access to DSC.

  • DSC does not support enterprise projects.

Follow-up Operations

After purchasing DSC, perform the following steps to start using it:

  1. Authorize access to assets on the asset management page. For details, see Allowing or Disallowing Access to Cloud Assets.
  2. Add and authorize data assets in DSC.
  3. Use the following functions based on your business needs:
    • Classification and grading (recommended): Identify sensitive information and perform classification and grading based on the data identification engine.
    • Risk assessment (recommended): Quickly identify risky assets and handle risks.
    • Data masking: Mask sensitive data to prevent sensitive information leakage.
    • Data watermarking: Add watermarks to databases, images, and documents to protect copyrights. This ensures security tracing and prevents data from being tampered with.
