Overview

Description

Enable server-side encryption (Encrypt with Service Key) for objects.

Rationale

Server-side encryption protects your data at rest.

Impact

Service key incurs an additional cost from accessing the KMS service.

Default Value

By default, objects are not encrypted.

Remediation guidance

Perform the following to configure the OSS bucket to use SSE-KMS:

Via the management console

  1. Login to the OSS Console
  2. Under Buckets, select the target bucket
  3. Click Basic Setting in the top middle of the console
  4. Under the Server-Side Encryption section, click on Configure
  5. Click KMS and select the KMS service key (alias/acs/oss)

Service-wide remediation

Recommended when many resources are affected: fix the platform baseline first so new resources inherit the secure setting, then remediate the existing flagged resources in batches.

Alibaba Cloud

Use Resource Directory guardrails, account baselines, and IaC modules so the secure setting is applied consistently across environments.

Operational rollout

  1. Fix the baseline first at the account, subscription, project, cluster, or tenant scope that owns this control.
  2. Remediate the currently affected resources in batches, starting with internet-exposed and production assets.
  3. Re-scan and track approved exceptions with an owner and expiry date.
