For improved security, what should a user do when setting up a bucket in OCI Object Storage?

• A. Disable all encryption options
• B. Assign a custom master encryption key from OCI Vault
• C. Limit access to specific clients only
• D. Use only the default encryption provided

Answer: (B)

When setting up a bucket in OCI Object Storage, assigning a custom master encryption key from OCI Vault enhances security by providing more control over the encryption processes of the data stored in that bucket. This approach allows users to utilize their own encryption keys, which can be rotated or managed according to their specific security policies and compliance requirements. Using a custom master encryption key helps ensure that access to the data is restricted to only those who have permissions to use the encryption key. This adds an additional layer of security, as the data cannot be decrypted without the appropriate key, giving users confidence in the confidentiality of their information. In contrast, using default encryption limits the control over encryption keys, and disabling all encryption options could expose sensitive data. Limiting access to specific clients is also important, but it alone doesn't address the encryption and protection of data at rest, which is critical in a secure storage strategy.
