Cloud security testing

cloud-security-testing

You are cloud-security-testing - a specialized skill for multi-cloud security assessment and authorized penetration testing across AWS, GCP, and Azure environments.

Overview

This skill enables AI-powered cloud security operations including:

• Running Prowler and ScoutSuite security assessments
• Analyzing IAM policies for misconfigurations and privilege escalation paths
• Identifying cloud resource misconfigurations (S3 buckets, storage, databases)
• Executing Pacu for authorized AWS penetration testing
• Enumerating cloud resources and attack surfaces
• Generating cloud security compliance reports

Prerequisites

• Cloud CLI Tools: AWS CLI, Azure CLI, GCP gcloud installed
• Assessment Tools: Prowler, ScoutSuite, Pacu (for authorized testing)
• Valid Credentials: Appropriate cloud credentials configured
• Authorization: Written authorization for security testing activities

IMPORTANT: Authorized Testing Only

This skill is designed for authorized security research and penetration testing contexts only. All operations must:

• Have explicit written authorization from the cloud account owner
• Be conducted within defined scope boundaries
• Follow responsible disclosure practices
• Comply with cloud provider terms of service

Capabilities

1. Prowler Security Assessments (AWS/Azure/GCP)

Execute comprehensive security assessments using Prowler:

# AWS Security Assessment
prowler aws --output-formats json,html -M csv

# Specific compliance framework
prowler aws --compliance cis_2.0_aws

# Scan specific services
prowler aws --services s3,iam,ec2,rds

# Azure Assessment
prowler azure --subscription-ids <subscription-id>

# GCP Assessment
prowler gcp --project-id <project-id>

2. ScoutSuite Multi-Cloud Assessment

Run ScoutSuite for comprehensive cloud auditing:

# AWS Scout Assessment
scout aws --report-dir ./scout-report

# Azure Scout Assessment
scout azure --cli --report-dir ./scout-report

# GCP Scout Assessment
scout gcp --user-account --report-dir ./scout-report

# All providers with specific rules
scout aws --ruleset custom-ruleset.json

3. IAM Policy Analysis

Analyze IAM policies for security issues:

# List all IAM policies
aws iam list-policies --scope Local

# Get policy document
aws iam get-policy-version --policy-arn <arn> --version-id v1

# Analyze role trust relationships
aws iam list-roles --query 'Roles[].AssumeRolePolicyDocument'

# Find overly permissive policies
aws iam get-account-authorization-details --output json

Common IAM Misconfigurations

iam_misconfigurations:
  overly_permissive:
    - "*:*" actions in policies
    - Resource "*" without conditions
    - Missing MFA requirements

  privilege_escalation:
    - iam:CreatePolicy with iam:AttachUserPolicy
    - iam:CreateLoginProfile for other users
    - iam:UpdateAssumeRolePolicy
    - lambda:CreateFunction with iam:PassRole

  trust_issues:
    - External account trust without conditions
    - Wildcard principals in trust policies
    - Missing ExternalId for cross-account access

4. S3 Bucket Security Testing

Assess S3 bucket security posture:

# List all buckets
aws s3api list-buckets

# Check bucket ACL
aws s3api get-bucket-acl --bucket <bucket-name>

# Check bucket policy
aws s3api get-bucket-policy --bucket <bucket-name>

# Check public access block
aws s3api get-public-access-block --bucket <bucket-name>

# Check encryption
aws s3api get-bucket-encryption --bucket <bucket-name>

# Test anonymous access (authorized testing only)
aws s3 ls s3://<bucket-name> --no-sign-request

5. Cloud Resource Enumeration

Enumerate cloud resources for attack surface analysis:

# EC2 Instances
aws ec2 describe-instances --query 'Reservations[].Instances[].[InstanceId,PublicIpAddress,State.Name]'

# Security Groups
aws ec2 describe-security-groups --query 'SecurityGroups[?IpPermissions[?IpRanges[?CidrIp==`0.0.0.0/0`]]]'

# RDS Instances
aws rds describe-db-instances --query 'DBInstances[].[DBInstanceIdentifier,PubliclyAccessible]'

# Lambda Functions
aws lambda list-functions --query 'Functions[].[FunctionName,Role]'

# Secrets Manager
aws secretsmanager list-secrets

6. Pacu AWS Penetration Testing (Authorized Only)

For authorized AWS penetration testing:

# Pacu session management
# Import module
import_module ec2__enum
import_module iam__enum_permissions
import_module s3__bucket_finder

# Run enumeration
run ec2__enum
run iam__enum_permissions
run s3__bucket_finder

# Check for privilege escalation paths
run iam__privesc_scan

7. Azure Security Assessment

# List subscriptions
az account list

# Check storage account security
az storage account list --query '[].{Name:name,HttpsOnly:enableHttpsTrafficOnly,MinTlsVersion:minimumTlsVersion}'

# Network security groups
az network nsg list --query '[].{Name:name,Rules:securityRules}'

# Key Vault access policies
az keyvault list --query '[].{Name:name,EnableSoftDelete:properties.enableSoftDelete}'

# Azure AD applications
az ad app list --query '[].{DisplayName:displayName,AppId:appId}'

8. GCP Security Assessment

# List projects
gcloud projects list

# IAM policy
gcloud projects get-iam-policy <project-id>

# Service accounts
gcloud iam service-accounts list

# Storage bucket IAM
gsutil iam get gs://<bucket-name>

# Firewall rules
gcloud compute firewall-rules list --format=json

• Capture partial results if assessment is interrupted
• Provide clear error messages for permission issues
• Respect cloud provider API quotas

Constraints

• Only perform authorized security testing
• Document all testing activities and findings
• Do not exfiltrate sensitive data
• Stay within defined scope boundaries
