Basically, the idea is that it used to be back in yield days, when you use GKE, the nodes had service accounts attached to them and all of the workloads that you ran would use the permissions of the node, and that had a whole host of issues. Get best practices to optimize workload costs. And that took a little while for me to get my head around. Data warehouse for business agility and insights. So, in a traditional environment, you might have something like active directory that determines what identity is and what groups and permissions an individual identity has access to. Warm-up: Create 10 GCP service accounts Grant the current user roles/iam.serviceAccountTokenCreator on one of these service accounts Detonation: Attempt to impersonate each of the service accounts The following grants SA_A to impersonate SA_B: The user executing the above command requires a number of items: The user requires the role roles/serviceusage.serviceUsageConsumer. So, if you have a piece of data, you can figure out who can touch it, but you can't say, well, what data can Tim touch? It's the system is different to what you're used to.

Even after revoking a users key, it does not prohibit them from aquiring someone elses key and using it. So, it used to be if I wanted -- Sorry, Tim, to keep picking on you -- but if I wanted Tim, for example, to be able to run a data proc job, I would grant Tim a data proc permission and at its face, it would look like it couldn't do anything other than data proc things, but because that then allowed Tim to create a data pro compute resource. Web-based interface for managing and monitoring cloud apps. In wrapping up, I wanted to highlight the benefits and a high-level overview around the operationalization of Service Account Impersonation within your GCP environment. By utilising service account impersonation we achieve a greater level of transparency and control. You have both machine ID and user identities. Dylan, actually, I don't think you've ever worked at Google Cloud. Get reference architectures and best practices. GCP third-party access in the wild Each vendor determines which method it uses to access its customers' environments. And that we included that in the repository and you can see what stack driver filter to add, to detect on that. So, you can think of a large Google cloud customer like Snap, for example, could arbitrarily say, I want to give Tim access to our production database and the permission to be able to view that role binding is one that you wouldn't have by default. Creating resources as a service account. We shouldn't be able to go from data proc to editor, to all the rest of the service accounts in the project."

Using identity federation, you can grant on-premises or multi-cloud workloads access to Google Cloud resources, without using a service account key. Service to prepare data for analysis and machine learning. Anton: We'll look them up and put the links. public, you can restrict access so only the identities you choose have access We then pass the impersonated credentials in to our list_buckets() function instead of our own. Google Cloud actually doesn't have that ability like you might have in sort of the active directory world. Dylan: So, when it comes to this particular problem, which is the privilege escalation and lateral movement within Google Cloud, the number of resources on it is actually pretty light, but there are some really luminary people that I can point to. If your Python program is running outside Google Cloud, then no, you must use credentials. It could both be something that gets permissions and something that receives permissions.
