📚 Introduction to GCP Security

Security is a crucial aspect of any cloud-based project. On Google Cloud Platform (GCP), managing access and permissions effectively ensures that your resources are secure and that only authorized users can perform specific actions. This chapter will guide you through the basics of GCP security, focusing on Identity and Access Management (IAM) and the Principle of Least Privilege.

🔐 Identity and Access Management (IAM)

What is IAM?

Identity and Access Management (IAM) is a framework of policies and technologies for ensuring that the right individuals have the appropriate access to technology resources. On GCP, IAM allows you to manage access to resources by defining who (identity) has what access (role) for which resource.

Key Components of IAM:

1. Members: These are the users, groups, or service accounts that need access to your resources.
2. Roles: A set of permissions that can be assigned to members. Roles define what actions members can perform.
3. Policies: Attach roles to members to define their access to resources.

Types of IAM Members:

• Google Accounts: Individual user accounts.
• Service Accounts: Special accounts used by applications or virtual machines.
• Google Groups: Collections of Google accounts.

Common IAM Roles:

• Viewer: Read-only access to resources.
• Editor: Read and write access to resources.
