Open-Source Cloud Security with Prowler: A Comprehensive Guide

Prowler is an open-source security tool designed to assess and improve the security posture of cloud infrastructure across AWS, Azure, Google Cloud, and Kubernetes. With the release of Prowler v5, it now includes enhanced security checks for multiple platforms, making it a powerful alternative to expensive Cloud Security Posture Management (CSPM) solutions.

Key Features:

• Multi-Cloud Support: AWS, Azure, Google Cloud, and Kubernetes.
• Compliance Checks: CIS, ISO27001, GDPR, HIPAA, and more.
• Continuous Monitoring: Real-time security assessments.
• Open-Source & Free: No licensing costs.

You Should Know:

Installation & Setup

1. Install Prowler (Linux/macOS):

git clone https://github.com/prowler-cloud/prowler 
cd prowler 
pip install -r requirements.txt 

2. Run Basic AWS Scan:

./prowler -p aws 

3. Scan Azure:

./prowler -p azure 

4. Scan Google Cloud:

./prowler -p gcp 

5. Scan Kubernetes:

./prowler -p kubernetes 

Advanced Usage

• Export Results to CSV:

  ./prowler -p aws -M csv 
  

• Check Specific Compliance (CIS Benchmark):

  ./prowler -p aws -c cis_aws 
  

• Run in Docker:

  docker run -ti --rm --name prowler \ 
  -v ~/.aws/credentials:/root/.aws/credentials:ro \ 
  toniblyx/prowler:latest -p aws 
  

Security Hardening Commands

• AWS CLI Security Checks:

  aws iam get-account-summary 
  aws iam list-users 
  aws iam list-roles 
  

• Kubernetes Security:

  kubectl get pods --all-namespaces 
  kubectl get secrets --all-namespaces 
  

• Azure Security Checks:

  az ad sp list --show-mine 
  az role assignment list --all 
  

What Undercode Say:

Prowler is a game-changer for cloud security, especially for smaller organizations that need robust security without high costs. By automating compliance checks and providing real-time insights, it bridges the gap between enterprise-grade security and open-source flexibility.

Expected Output:

[bash] Running AWS checks... 
[bash] 1.1 Ensure multi-factor authentication (MFA) is enabled for all IAM users 
[bash] 1.2 Ensure no root account access key exists 
[bash] 1.3 Ensure credentials unused for 90 days are disabled 

Prediction:

As cloud adoption grows, open-source security tools like Prowler will become essential for maintaining compliance and preventing breaches. Expect more integrations with AI-driven threat detection in future releases.
