Lesson 11 — Enterprise Google Cloud Attack Paths

Welcome

Modern cloud attacks rarely target a single resource.

Instead, attackers attempt to move through interconnected cloud services, identities, networks, and workloads until they reach valuable business assets.

This sequence of interconnected opportunities is known as an Attack Path.

For Cloud Penetration Testers, identifying attack paths is significantly more valuable than identifying isolated security findings because attack paths demonstrate how multiple small weaknesses can combine to create a serious business risk.

This lesson focuses on understanding enterprise Google Cloud attack paths, mapping relationships between cloud resources, identifying potential business impact, and prioritizing security improvements.

Important: This lesson focuses on identifying and analyzing attack paths for defensive purposes during authorized security assessments. It does not teach exploitation techniques.

Learning Objectives

After completing this lesson, you will be able to:

Understand enterprise cloud attack paths.
Explain attack path analysis.
Identify relationships between cloud resources.
Understand cloud trust boundaries.
Assess identity-based attack paths.
Review infrastructure dependencies.
Prioritize security findings based on business impact.
Recommend defensive improvements.

Business Scenario

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

A multinational retail organization has deployed workloads across multiple Google Cloud Projects supporting:

Customer Web Applications
Internal APIs
Google Kubernetes Engine (GKE)
Cloud SQL
Cloud Storage
BigQuery
Serverless Applications
Machine Learning Services

Rather than reviewing each service independently, the customer wants to understand:

How resources are connected.
Which systems are most critical.
Which combinations of weaknesses create the greatest business risk.
How to prioritize remediation efforts.

Your role is to identify potential attack paths and provide recommendations to strengthen the organization’s cloud security architecture.

What is an Attack Path?

An attack path represents the sequence of relationships that could allow an attacker to move from one cloud resource or identity toward a higher-value target.

An attack path may involve:

Identities
IAM Roles
Service Accounts
Virtual Machines
Cloud Storage
Databases
Kubernetes Clusters
APIs
Networking Components

The objective is to understand how seemingly independent resources interact within an enterprise environment.

Sensitive Business Data

This diagram illustrates how business services depend on one another.

During an assessment, understanding these relationships helps prioritize security reviews.

Cloud Trust Boundaries

Enterprise cloud environments contain multiple trust boundaries.

Examples include:

Internet
Public Applications
Internal Applications
Identity Services
Administrative Networks
Kubernetes Clusters
Production Projects
Development Projects
Shared Services

Security assessments should verify that appropriate controls exist between these trust boundaries.

Identity Attack Paths

Identity is often the central component connecting cloud resources.

Review relationships involving:

Users
Groups
Service Accounts
IAM Roles
Workload Identity
Administrative Roles

Evaluate whether access assignments align with the Principle of Least Privilege and organizational governance.

Infrastructure Relationships

Enterprise workloads depend on multiple cloud services.

Examples include:

Application

↓

Cloud Functions

↓

Service Account

↓

Secret Manager

↓

Cloud SQL

↓

Cloud Storage

Mapping these relationships helps identify where stronger segmentation or access controls may reduce overall risk.

Enterprise Resource Dependencies

Review dependencies between:

Projects
Shared VPCs
Compute Engine
GKE Clusters
Cloud Storage
Cloud SQL
Pub/Sub
BigQuery
Cloud Functions

Document critical dependencies and identify single points of failure where appropriate.

Network Attack Surface Review

Review the enterprise network architecture.

Assess:

Public IP Addresses
Firewall Rules
Shared VPC
Private Service Connect
VPN Connections
Cloud NAT
Load Balancers
Hybrid Connectivity

Determine whether network segmentation supports organizational security objectives.

Business Impact Assessment

Not every security finding presents the same level of organizational risk.

Evaluate each finding based on:

Business Criticality
Data Sensitivity
Availability Requirements
Regulatory Impact
Customer Impact
Financial Impact
Operational Impact

This helps organizations prioritize remediation activities.

Risk Prioritization

After mapping attack paths, classify findings using organizational risk criteria.

Risk	Description
Critical	Immediate business risk requiring urgent action
High	Significant security exposure
Medium	Moderate risk requiring planned remediation
Low	Minor security improvement
Informational	Observation or best practice recommendation

Prioritize findings based on overall business impact rather than technical complexity alone.

Documentation

During enterprise assessments, document:

Resource relationships
Identity dependencies
Network architecture
Trust boundaries
Critical business assets
Security observations
Risk ratings
Supporting evidence
Recommended remediation

Clear documentation helps technical teams understand why improvements are necessary.

Enterprise Best Practices

Organizations with mature cloud security programs typically:

Maintain documented cloud architecture.
Apply Zero Trust principles.
Implement least privilege.
Segment workloads appropriately.
Monitor identity activity.
Review cloud architecture regularly.
Perform periodic attack path analysis.
Validate security controls through regular assessments.
Prioritize remediation based on business impact.
