To organize GCP projects based on different business units and manage IAM permissions, you should create an organization node and assign folders for each business unit. This approach allows you to logically separate projects under folders and apply IAM policies at the folder level.

Step-by-Step:

Create Organization Node: Ensure that your GCP account is linked to an organization.

Create Folders for Business Units:

Navigate to the GCP Console > IAM & Admin > Resource Manager.

Create a folder for each business unit under the organization node.

Move Projects to Folders:

Move existing projects into the respective folders according to the business unit.

Set IAM Policies:

Assign IAM roles and permissions at the folder level to manage access for each business unit independently.

Monitor and Manage: Use Cloud Audit Logs and other GCP tools to monitor the activities and ensure compliance with the organization’s policies.

Managing IAM Policies

MACsec (Media Access Control Security) relies on a shared secret (a pre-shared key, made up of a Connectivity Key Name, CKN, and Connectivity Association Key, CAK) to establish a secure session between the two endpoints. If the session is "operationally down," it indicates a cryptographic mismatch.

Extracts:

"MACsec is operationally down on my Cloud Interconnect connection... The issue could be caused by one of the following: The active keys on your on-premises router and Google's edge routers don't match." (Source 3.1)

The troubleshooting guide further specifies checking that the "active CKN, CAK, and start times on your on-premises router match the values that MACsec for Cloud Interconnect displays." (Source 3.1)

Therefore, the primary and most common step to resolve a "MACsec is operationally down" status is to verify that the cryptographic keys (the pre-shared key) are correctly configured and match on both the on-premises and Google Cloud routers.

Use Cloud Data Loss Prevention (DLP) with cryptographic hashing:

Cloud DLP allows you to de-identify sensitive data using several techniques, including cryptographic hashing.

Choose a suitable hashing algorithm like SHA-256 for non-reversible anonymization.

This method converts the original data into a fixed-length hash that does not preserve the original data's format or character set.

Set up a Cloud DLP job to scan your data sources, identify PHI, and apply the cryptographic hashing transformation.
