GCP > CIS v1 > 1 Identity and Access Management > 1.07 Ensure that Separation of duties is enforced while assigning service account related roles to users (Not Scored)

Configures auditing against a CIS Benchmark item.

Level: 2 (Not Scored)

Built-in/Predefined IAM role Service Account admin allows user/identity to create, delete, manage service account(s). Built-in/Predefined IAM role Service Account User allows user/identity (with adequate privileges on Compute and App Engine) to assign service account(s) to Apps/Compute Instances.

Separation of duties is the concept of ensuring that one individual does not have all necessary permissions to be able to complete a malicious action. In Cloud IAM - service accounts, this could be an action such as using a service account to access resources that user should not normally have access to. Separation of duties is a business control typically used in larger organizations, meant to help avoid security or privacy incidents and errors. It is considered best practice.

Any user(s) should not have Service Account Admin and Service Account User , both roles assigned at a time.

Configures auditing against a CIS Benchmark item.

Level: 1 (Scored)

Storage Access Logging generates a log that contains access records for each request made to the Storage bucket. An access log record contains details about the request, such as the request type, the resources specified in the request worked, and the time and date the request was processed. Cloud Storage offers access logs and storage logs in the form of CSV files that can be downloaded and used for analysis/incident response. Access logs provide information for all of the requests made on a specified bucket and are created hourly, while the daily storage logs provide information about the storage consumption of that bucket for the last day. The access logs and storage logs are automatically created as new objects in a bucket that you specify. An access log record contains details about the request, such as the request type, the resources specified in the request worked, and the time and date the request was processed. While storage Logs helps to keep track the amount of data stored in the bucket. It is recommended that storage Access Logs and Storage logs are enabled for every Storage Bucket.

The Kubernetes Network Policy API allows the cluster administrator to specify what pods are allowed to communicate with each other.

GCP > CIS v1 > 7 Kubernetes Engine > 7.13 Ensure Kubernetes Cluster is created with Alias IP ranges enabled (Scored)

Configures auditing against a CIS Benchmark item.

Level: 1 (Scored)

Google Cloud Platform Alias IP Ranges lets you assign ranges of internal IP addresses as aliases to a virtual machine's network interfaces. This is useful if you have multiple services running on a VM and you want to assign each service a different IP address.

GCP > CIS v1 > 7 Kubernetes Engine > 7.14 Ensure PodSecurityPolicy controller is enabled on the Kubernetes Engine Clusters (Scored)

Configures auditing against a CIS Benchmark item.

Level: 1 (Scored)

A Pod Security Policy is a cluster-level resource that controls security sensitive aspects of the pod specification. The PodSecurityPolicy objects define a set of conditions that a pod must run with in order to be accepted into the system, as well as defaults for the related fields.

GCP > CIS v1 > 7 Kubernetes Engine > 7.15 Ensure Kubernetes Cluster is created with Private cluster enabled (Scored)

Configures auditing against a CIS Benchmark item.

Level: 1 (Scored)

A private cluster is a cluster that makes your master inaccessible from the public internet. In a private cluster, nodes do not have public IP addresses, so your workloads run in an environment that is isolated from the internet. Nodes have addressed only in the private RFC 1918 address space. Nodes and masters communicate with each other privately using VPC peering.

GCP > CIS v1 > 7 Kubernetes Engine > 7.17 Ensure default Service account is not used for Project access in Kubernetes Clusters (Scored)

Configures auditing against a CIS Benchmark item.

Level: 2 (Scored)

A service account is an identity that an instance or an application can use to run API requests on your behalf. This identity is used to identify applications running on your virtual machine instances to other Google Cloud Platform services. By default, Kubernetes Engine nodes are given the Compute Engine default service account. This account has broad access by default, making it useful to a wide variety of applications, but it has more permissions than are required to run your Kubernetes Engine cluster.

GCP > CIS v1 > 7 Kubernetes Engine > 7.18 Ensure Kubernetes Clusters created with limited service account Access scopes for Project access (Scored)

Configures auditing against a CIS Benchmark item.

Level: 1 (Scored)

Access scopes are the legacy method of specifying permissions for your instance. Before the existence of IAM roles, access scopes were the only mechanism for granting permissions to service accounts. By default, your node service account has access scopes.
