AWS CSPM Playbook

Cloud Security Posture Management (CSPM) Cheatsheet

Imagine your AWS environment as a vast digital empire—a sprawling metropolis with millions of interconnected resources, each representing potential treasure or vulnerability. In this cyber realm, Cloud Security Posture Management (CSPM) serves as your empire's intelligence network, constantly surveying every corner, identifying weaknesses, and orchestrating defenses against both external invasions and internal threats. But unlike traditional security tools that guard specific gates, CSPM is the all-seeing eye that monitors your entire cloud kingdom, ensuring every resource, policy, and configuration aligns with security best practices.

This comprehensive playbook transcends typical security guides by presenting a tactical battleground between two formidable adversaries: Alex "Shadow", a sophisticated threat actor who exploits cloud misconfigurations with surgical precision, and Morgan "Guardian", an elite cloud security architect who wields CSPM tools like a master strategist. Through their digital warfare, we'll explore real-world attack scenarios, defensive strategies, and the cutting-edge tools that shape modern cloud security.

In today's cloud-first world, where organizations deploy thousands of resources across multiple AWS services, traditional perimeter security crumbles like ancient castle walls against modern siege engines. CSPM emerges as the new paradigm—a proactive, intelligent approach that doesn't just react to threats but anticipates and prevents them through continuous monitoring, automated remediation, and strategic policy enforcement.

Learning Objectives

By the end of this comprehensive CSPM deep dive, you will:

The CSPM Ecosystem: Power, Complexity, and Continuous Vigilance

Before diving into the tactical warfare between Alex and Morgan, let's explore the CSPM landscape that makes cloud security both critically important and inherently complex.

Core CSPM Concepts:

• Security Posture: The overall security status of your cloud environment, including configurations, policies, and compliance states.

• Continuous Monitoring: Real-time assessment of cloud resources for security misconfigurations and policy violations.

• Policy as Code: Security policies defined as code for consistent, repeatable enforcement across environments.

• Automated Remediation: Immediate response to security violations through automated corrective actions.

• Compliance Frameworks: Industry standards and regulations mapped to cloud security controls (CIS, SOC2, PCI-DSS, etc.).

Key CSPM Components and Their Strategic Value:

Component Description Strategic Security Value CloudQuery SQL-based cloud asset inventory and security analysis Provides comprehensive visibility into cloud resources and their configurations across multiple providers Cloud Custodian Policy-driven cloud resource management and remediation Enables automated enforcement of security policies with real-time violation response AWS Config Native AWS configuration monitoring and compliance Continuously tracks resource configurations and evaluates against defined rules AWS Security Hub Centralized security findings aggregation Consolidates security insights from multiple tools into a unified dashboard Prowler Open-source cloud security assessment Performs comprehensive security checks against industry benchmarks ScoutSuite Multi-cloud security auditing platform Provides detailed security posture assessment across cloud environments

Why CSPM is the New Battlefield:

Modern cloud environments present unique challenges that make CSPM essential:

1. Scale and Complexity: Organizations manage thousands of resources across dozens of services, making manual oversight impossible.

2. Dynamic Nature: Cloud resources are constantly created, modified, and destroyed, requiring continuous monitoring.

3. Shared Responsibility: Cloud providers secure the infrastructure, but customers must secure their configurations and data.

4. Compliance Requirements: Regulatory frameworks demand continuous compliance monitoring and reporting.

5. Advanced Threat Landscape: Attackers increasingly target cloud misconfigurations as the path of least resistance.

Understanding these dynamics sets the stage for our security battle between Alex and Morgan.

The Attacker's Arsenal: Alex "Shadow's" CSPM Exploitation Playbook

Alex "Shadow" approaches cloud exploitation with the precision of a digital archaeologist, systematically uncovering misconfigurations and policy gaps that organizations unknowingly expose. Let's explore Alex's comprehensive attack methodology against cloud security posture.

Phase 1: Cloud Infrastructure Reconnaissance – Mapping the Digital Kingdom

Alex's reconnaissance phase focuses on building a comprehensive map of the target's cloud infrastructure through multiple intelligence-gathering vectors.

1.1. Public Cloud Asset Discovery:

Alex begins by identifying publicly accessible cloud resources and services through various reconnaissance techniques.

CloudQuery-Powered Asset Discovery:

# Install CloudQuery CLI

curl -L https://github.com/cloudquery/cloudquery/releases/latest/download/cloudquery_linux_amd64 -o cloudquery

chmod +x cloudquery

  

# Configure AWS plugin for asset discovery

cat > aws_config.yml << EOF

kind: source

spec:

name: "aws"

path: "cloudquery/aws"

version: "LATEST"

destinations: ["postgresql"]

spec:

regions:

- "us-east-1"

- "us-west-2"

- "eu-west-1"

accounts:

- id: "123456789012"

local_profile: "target-profile"

EOF

  

# Execute comprehensive asset inventory

./cloudquery sync aws_config.yml

  

# Query for unencrypted S3 buckets

psql -h localhost -d cloudquery -c "

SELECT bucket_name, region, creation_date

FROM aws_s3_buckets

WHERE server_side_encryption_configuration IS NULL

ORDER BY creation_date DESC;"

S3 Bucket Enumeration for Intelligence Gathering:

# Use awscli for bucket discovery

aws s3 ls --profile target-profile

  

# Enumerate bucket permissions and policies

for bucket in $(aws s3api list-buckets --query 'Buckets[].Name' --output text --profile target-profile); do

echo "Analyzing bucket: $bucket"

aws s3api get-bucket-policy --bucket $bucket --profile target-profile 2>/dev/null || echo "No policy"

aws s3api get-bucket-acl --bucket $bucket --profile target-profile

aws s3api get-bucket-encryption --bucket $bucket --profile target-profile 2>/dev/null || echo "No encryption"

echo "---"

done

1.2. EC2 Security Group Analysis:

Alex systematically identifies EC2 instances with overly permissive security group configurations.

CloudQuery EC2 Security Analysis:

-- Find EC2 instances with SSH access from anywhere

SELECT

i.instance_id,

i.instance_type,

i.state,

i.public_ip_address,

sg.group_id,

sg.group_name

FROM aws_ec2_instances i

JOIN aws_ec2_instance_security_groups isg ON i.instance_id = isg.instance_id

JOIN aws_ec2_security_groups sg ON isg.group_id = sg.group_id

JOIN aws_ec2_security_group_ip_permissions p ON sg.group_id = p.group_id

WHERE p.from_port <= 22

AND p.to_port >= 22

AND p.ip_ranges LIKE '%0.0.0.0/0%'

AND i.state = 'running';
