For a client concerned about the control of their encryption keys and not wanting to store these keys within the same cloud service provider (CSP) as the data, the following solutions are suitable:

Customer-supplied encryption keys (A):

With customer-supplied encryption keys, clients manage their own encryption keys outside of Google Cloud and supply them to encrypt and decrypt data. This ensures that the keys are not stored in Google Cloud, providing full control over the key management process.

Cloud External Key Manager (D):

Cloud External Key Manager (EKM) allows clients to integrate an external key management system (KMS) with Google Cloud services. This setup enables the client to keep their encryption keys outside Google Cloud while still allowing the data to be encrypted and decrypted within Google Cloud services. This method offers an additional layer of security and control over the encryption keys.

These options provide robust solutions for clients requiring external key management and enhanced control over their encryption processes.

To enforce access control policies for applications and resources in Google Cloud, the recommended service is Identity-Aware Proxy (IAP).

Identity-Aware Proxy (IAP):

IAP allows you to control access to your applications and resources based on the identity of the user and the context of the request. It integrates with IAM to provide fine-grained access control, ensuring that only authorized users can access specific resources.

IAP helps enforce security policies at the application layer, providing an additional layer of protection beyond traditional network-based security measures.

The goal is to detect cryptocurrency mining software using Security Command Center (SCC).

Security Command Center Threat Detection Services: SCC Premium and Enterprise tiers offer various specialized threat detection services.

Virtual Machine Threat Detection (VMTD): This service is explicitly designed to scan virtual machines (Compute Engine instances and GKE nodes) for specific threats, including cryptocurrency mining software. It operates at the hypervisor level, performing deep scans of VM memory and disks.Extract Reference: "Virtual Machine Threat Detection (VMTD) helps you detect potential threats, such as cryptocurrency mining and malware, within your Compute Engine instances and GKE nodes." (Google Cloud Documentation: "Virtual Machine Threat Detection overview | Security Command Center" -

Extract Reference: "This service scans virtual machines to detect potentially malicious applications, such as cryptocurrency mining software, kernel-mode rootkits, and malware running in compromised cloud environments." (Google Cloud Documentation: "Virtual Machine Threat Detection overview | Security Command Center" -

Let's evaluate the other options:

A. Web Security Scanner: This service scans for common web application vulnerabilities like XSS, Flash injection, and mixed content. It is not designed to detect runtime threats like cryptocurrency mining software.

B. Container Threat Detection: While Container Threat Detection (CTD) also detects cryptocurrency mining, it specifically focuses on runtime threats within GKE containers. The question asks for detection of "cryptocurrency mining software" generally, and VMs are a common target for such activity (and GKE nodes are VMs). VMTD provides a more general detection across Compute Engine VMs and GKE nodes for this specific type of threat. If the context explicitly mentioned containers or Cloud Run, CTD would be the more specific answer. However, for a general detection of "software" on "workloads", and given that VMTD explicitly lists "cryptocurrency mining software" for VMs, it is the most direct and broadly applicable answer among the choices.

C. Rapid Vulnerability Detection: This service actively scans internet-exposed assets for network vulnerabilities and misconfigurations. It focuses on finding known vulnerabilities, not detecting active malicious processes like cryptocurrency mining.

Given the direct and explicit mention of cryptocurrency mining detection for VMs in its documentation, Virtual Machine Threat Detection is the correct SCC service to use.

- First, you create or use an existing key in a supported external key management partner system. This key has a unique URI or key path.

- Next, you grant your Google Cloud project access to use the key, in the external key management partner system.

- In your Google Cloud project, you create a Cloud EKM key, using the URI or key path for the externally-managed key.
