Runbook 03 — Enterprise Cloud Attack Path & Executive Risk Assessment

Runbook Information

Item	Details
Runbook ID	CPS-RB-003
Category	Executive Security Assessment
Audience	Cloud Security Architects, Cloud Penetration Testers, Red Teams, Security Consultants, Security Managers
Estimated Duration	4–8 Hours
Environment	AWS, Azure, Google Cloud, Kubernetes
Prerequisites	Runbook 01 & Runbook 02 Completed

Purpose

Finding vulnerabilities is only one part of a professional cloud penetration test.

Enterprise customers expect consultants to answer questions such as:

How could an attacker compromise our cloud environment?
Which weaknesses present the highest business risk?
What should we fix first?
How much risk does the organization currently have?
What is the likelihood of a real-world compromise?

This runbook focuses on transforming technical findings into business-focused attack paths and executive recommendations.

Enterprise Scenario

CloudNova Technologies has completed a comprehensive cloud security assessment for FinSecure Bank Ltd.

The assessment identified multiple weaknesses across AWS and Kubernetes.

Senior leadership now requires:

Attack path analysis
Business risk assessment
Executive summary
Prioritized remediation roadmap
Board-level presentation

You have been assigned to prepare the final executive deliverables.

Present Findings

Phase 1 — Review Assessment Findings

Collect all validated findings from the technical assessment.

Examples:

IAM Review
Storage Review
Compute Review
Kubernetes Review
Networking Review
Logging Review
Container Security Review

Checklist

Findings validated
Evidence collected
Duplicate findings removed
False positives eliminated

Phase 2 — Categorize Findings

Group findings into security domains.

Domain	Example Findings
Identity	Administrator without MFA
Storage	Public S3 Bucket
Compute	IMDSv1 Enabled
Network	SSH Open to Internet
Kubernetes	Cluster-admin Service Accounts
Containers	Privileged Containers
Logging	CloudTrail Disabled
Governance	Missing Security Policies

Phase 3 — Identify Attack Paths

Attack paths explain how attackers combine multiple weaknesses.

Example:

Internet

↓

Public Application

↓

Container Exploit

↓

Service Account

↓

IAM Role

↓

Administrator Privileges

↓

Amazon S3

↓

Customer Records

Example Attack Path 2

Phishing

↓

Developer Credentials

↓

AWS Console

↓

AssumeRole

↓

Administrator

↓

CloudTrail Disabled

↓

Data Exfiltration

Example Attack Path 3

GitHub Repository

↓

Hardcoded AWS Keys

↓

IAM User

↓

Lambda

↓

Secrets Manager

↓

Production Database

Phase 4 — Map the Cloud Kill Chain

For each attack path, identify the attack phases.

Kill Chain Phase	Example
Reconnaissance	Public DNS
Initial Access	Phishing
Credential Access	AWS Access Keys
Enumeration	IAM Roles
Privilege Escalation	AssumeRole
Lateral Movement	EC2 → S3
Collection	Customer Database
Exfiltration	S3 Download
Impact	Data Breach

Phase 5 — Business Impact Analysis

For every finding, determine the impact on the organization.

Consider:

Customer Data
Financial Loss
Operational Downtime
Regulatory Penalties
Reputation
Legal Liability
Business Continuity

Example

Finding	Business Impact
Public S3 Bucket	Customer Data Exposure
Admin Without MFA	Full Cloud Compromise
CloudTrail Disabled	Limited Incident Investigation
Cluster-admin Service Account	Kubernetes Takeover

Phase 6 — Risk Rating

Evaluate each finding using:

Likelihood
Technical Impact
Business Impact
Exploitability
Existing Controls

Enterprise Risk Matrix

Likelihood	Impact	Risk
High	Critical	Critical
High	High	High
Medium	High	High
Medium	Medium	Medium
Low	Medium	Low

Phase 7 — Executive Risk Register

Example:

Finding	Risk	Business Owner	Priority
Public S3 Bucket	Critical	Cloud Team	P1
Admin Without MFA	Critical	IAM Team	P1
Cluster-admin Accounts	High	Kubernetes Team	P2
Missing Network Policies	High	Platform Team	P2
IMDSv1 Enabled	Medium	Infrastructure Team	P3

Phase 8 — Prioritize Remediation

Immediate (0–30 Days)

Enable MFA
Remove public storage
Rotate exposed credentials
Disable unnecessary administrator access
Remove wildcard IAM permissions

Short-Term (30–90 Days)

Harden Kubernetes
Implement Network Policies
Enable CloudTrail
Configure GuardDuty
Secure CI/CD pipelines

Long-Term (90–180 Days)

Zero Trust Architecture
Continuous Compliance
CSPM
Runtime Threat Detection
Security Automation
Quarterly Cloud Pentests

Phase 9 — Executive Dashboard

Summarize the assessment.

Metric	Result
Critical Findings	4
High Findings	9
Medium Findings	14
Low Findings	8
Cloud Accounts Reviewed	6
Kubernetes Clusters	3
AWS Services Reviewed	18
Attack Paths Identified	5

Phase 10 — Executive Summary

Your executive summary should answer:

Current Security Posture

Example:

The organization demonstrates a moderate level of cloud security maturity; however, several critical identity and storage weaknesses significantly increase the risk of unauthorized access to sensitive customer data.

Top Business Risks

Identity compromise
Data exposure
Kubernetes compromise
Cloud misconfiguration
Weak monitoring

Highest Priority Recommendations

Enforce Multi-Factor Authentication
Reduce IAM privileges
Remove public storage
Harden Kubernetes
Enable continuous monitoring

Phase 11 — Board Presentation

Recommended agenda:

Engagement Overview
Assessment Scope
Cloud Architecture
Security Posture
Critical Findings
Attack Path Demonstrations
Business Impact
Risk Register
Remediation Roadmap

Common Executive Questions

Prepare to answer:

What is our biggest security risk today?
How could an attacker compromise our cloud?
Which findings require immediate action?
What are the financial and regulatory implications?
How does our security posture compare to industry best practices?
What investments should we prioritize over the next 12 months?

Best Practices

Explain technical findings in business language.
Focus on attack paths rather than isolated vulnerabilities.
Prioritize recommendations based on risk reduction.
Include measurable remediation milestones.
Use visual diagrams to communicate complex attack scenarios.
Align recommendations with frameworks such as CIS Controls, NIST CSF and ISO 27001.
Present actionable recommendations instead of only identifying problems.

Success Criteria

This runbook is successfully completed when:

Technical findings have been translated into business risks.
