Lesson 01 — Google Cloud Offensive Security Foundations

Welcome

Welcome to the Google Cloud Penetration Testing module.

In the previous modules, you learned how to assess Amazon Web Services (AWS) and Microsoft Azure environments from an offensive security perspective.

This module focuses on Google Cloud Platform (GCP)—Google’s enterprise cloud platform used by startups, Fortune 500 companies, financial institutions, healthcare providers, telecommunications providers, and government organisations worldwide.

As a Cloud Penetration Tester, your responsibility is to identify security weaknesses in Google Cloud environments, validate cloud security controls, assess business risk, and provide professional remediation recommendations.

Throughout this module, you will learn how enterprise consultants perform authorised Google Cloud security assessments using industry-standard methodologies.

Learning Objectives

After completing this lesson, you will be able to:

Understand Google Cloud Platform from an offensive security perspective.
Explain the responsibilities of a Google Cloud Penetration Tester.
Understand Google’s shared responsibility model.
Identify common Google Cloud attack surfaces.
Explain the Google Cloud penetration testing lifecycle.
Understand the structure of this learning module.

Why Google Cloud Matters

Google Cloud Platform powers some of the world’s largest cloud-native environments.

Organisations use GCP to host:

Enterprise Applications
Web Applications
APIs
Kubernetes Platforms
Artificial Intelligence workloads
Data Analytics
Machine Learning
Serverless Applications
Multi-Cloud Infrastructure

Because these environments often contain sensitive business data and critical workloads, securing Google Cloud environments has become a high priority for modern organisations.

Business Scenario

You are working as a Cloud Penetration Tester at CloudNova Technologies.

A global software company has recently migrated several production workloads into Google Cloud Platform.

The customer requests an authorised penetration testing engagement to validate the security of their cloud environment before expanding the deployment globally.

Your responsibilities include:

Reviewing Google Cloud architecture.
Identifying attack surfaces.
Assessing identity and access management.
Reviewing networking and cloud infrastructure.
Evaluating security controls.
Producing executive and technical reports.

What is Google Cloud Offensive Security?

Google Cloud Offensive Security is the practice of identifying, validating, and documenting security weaknesses within Google Cloud environments through authorised security assessments.

Unlike traditional infrastructure penetration testing, Google Cloud engagements focus heavily on:

Cloud identities
IAM permissions
Cloud-native services
Resource misconfigurations
Cloud networking
Data exposure
Security governance
Enterprise cloud architecture

The objective is to improve the organisation’s security posture while minimising business risk.

Google Cloud Shared Responsibility Model

Understanding responsibility boundaries is essential before beginning any assessment.

Google is responsible for:

Physical data centres
Global infrastructure
Physical networking
Hypervisors
Core managed cloud platform

Customers are responsible for:

IAM configuration
Cloud resources
Virtual Machines
Kubernetes clusters
Storage
Networking
Applications
Secrets
Data protection
Security monitoring

Cloud Penetration Testers primarily assess the customer’s implementation.

Common Google Cloud Attack Surfaces

Typical enterprise attack surfaces include:

Google Cloud IAM
Service Accounts
Cloud Storage
Compute Engine
Virtual Private Cloud (VPC)
Secret Manager
Cloud Functions
Google Kubernetes Engine (GKE)
Cloud SQL
Cloud APIs
Public Load Balancers
Identity Federation

Each of these services will be explored throughout this module.

Next Lesson

➡️ Lesson 02 — Google Cloud IAM

In the next lesson, you will explore Google Cloud Identity and Access Management (IAM), including principals, roles, permissions, service accounts, and enterprise identity architecture. Understanding IAM is fundamental before assessing privilege management and cloud access controls within Google Cloud environments.
