Q

Resource Hierarchy

A

Google Cloud resources are organized hierarchically. This allows us to map the enterprise’s operational structure to GCP, and to manage access control and permissions for groups of related resources.

Top-level node - Organization resource
provides central visibility and control over all resources.

Next in the hierarchy are Folders.
Used for isolating requirements for different departments and teams.

Next in the hierarchy are Projects.
They contain computing, storage and networking resources.

Q

What is Cloud Identity

A

A unified identity, access, app, and endpoint management (IAM/EMM) platform.

  • give users access to apps with single sign on
  • multi factor authentication
  • endpoint management enforces policies for personal and corporate devices.

Q

BeyondCorp

A

Google’s Zero trust solution, that let’s employees work from anywhere without having to log into VPN.

BeyondCorp allows for single sign-on, access control policies, access proxy, and user- and device-based authentication and authorization. The BeyondCorp principles are:

  • Access to services must not be determined by the network from which you connect
  • Access to services is granted based on contextual factors from the user and their device
  • Access to services must be authenticated, authorized, and encrypted

Q

VPC Service Controls

A

Used to create perimeters that protect the resources and data of services specified.
Following controls:
1. Clients within a perimeter do not have access to resources outside the perimeter.
2. Data cannot be copied to unauthorized resources outside the perimeter.
3. Data exchange between clients and resources separated by perimeter is secured by ingress and egress rules.
4. Context-aware access to resources is based on client attributes.

Created at the organization level.

    • can be based on the billing account or GCP project
    • can be triggered as a % previous month spend or fixed amount
  • Billing export
    store detailed information in a location which can be analyzed later, like in Big Query or Cloud Storage
  • Reports
    Visual tool
  • Quotas
    prevent overconsumption of resources
    Rate quota - Resets after a certain time
    Allocation quota - Fixed quotas, for example, 5 networks per project. Can be raised by Google support.
30
Q

Resources organization

A

The main way to organize the resources we use in GCP

All resources in a project should have a common business objective.

This helps in setting up policies that follow the principle of least privilege.

Organization

  • Folder
    • Folder
      • Folder
        • Project
          • Resources

Policies are inherited downwards. Each of the elements above is a point where policies can be defined.

31
Q

Google Cloud Security Responsibility

A

Google:

  • Managing infrastructure security
  • helps with best practices, templates, products, and solutions.

Customer:
- responsible for securing their data

32
Q

Project attributes

A
  • Project ID - globally unique - by client - immutable
  • Project name - not unique - by client - mutable
  • Priject number - globally unique - by GCP - Immutable
33
Q

Folders

A

Provide flexible management
Can be used to assign policies for specific departments.

The organization node is mandatory to use this.

We can move projects to folders at any time.

34
Q

Organization node

A

Top of hierarchy

Special roles:

  • Organization Policy Administrator
  • Project Creator

GSuite automatically creates an organization node, if the client doesn’t have this, they can use Client Identity to create one.

35
Q

Hierarchy policies

A

The more generous policies are accepted.

If project says Bob can access GCS while Org policy says Bob can’t access, the final result would be Bob being able to access GCS,

36
Q

IAM Policy

A
  • who (google group, google account, gsuite/cloud identity domain)
  • can do what (Roles: Primitive, Predefined, Custom)
  • on which resource

Primitive roles: Very coarse
Owner, Editor, Viewer, Billing Administrator

Predefined roles: A little finer control on access.
E.g. Instance Admin Role - specific to instance service.

Custom roles can be used only at project and organization level, and cannot be used at folder level.

37
Q

Service Account

A

SAs, control server to server interactions.
Used to authenticate one service to another.
Used to control privileges used by resources.
Identified with email address:
PROJECT_NUMBER-compute@developer.gserviceaccount.com

They use cryptographic keys/tokens to manage access. They do not have passwords.

A predefined or custom role can be assigned to the service account.

A service account also acts as a resource, so an IAM policy can be attached to it.
