Vertex AI instance disks not encrypted with a Customer Managed Key (CMK) misconfiguration detected i

Rule Details

Cortex AppSec Rule ID	APPSEC2_GCP_21
Category - Subcategory	Storage - Encryption
Provider	GCP
Severity	MEDIUM
Framework	Terraform, Terraform Plan

Impact

This rule is assessing whether instance disks in Vertex AI are encrypted using a Customer Managed Key (CMK). This is critical in providing a higher level of security for your data at rest. By using CMK, you have more control over your cryptographic key, increasing data protection. Forgoing use of a CMK could potentially lead to sensitive data being exposed or compromised. The encryption you employ should be as strong as possible to ensure maximum data security.

How to Fix

Resource: google_notebooks_instance

• Arguments: kms_key, disk_encryption

To fix this issue, you need to specify a Customer Managed Key (CMK) for encrypting the Vertex AI instance disks. You can do this by setting the kms_key field and the disk_encryption to CMEK.

The above code is secure because it ensures that the Vertex AI instance disks are encrypted with a CMK. This provides better encryption management and control, as well as an added layer of security for the data stored in these disks. The data can only be decrypted with the specified key which is under the control of the customer, making it much harder for unauthorized persons to access the data. [source,go]
