Description

Prowler is an Open Source security tool to perform AWS, Azure, Google Cloud and Kubernetes security best practices assessments, audits, incident response, continuous monitoring, hardening and forensics readiness, and also remediations! We have Prowler CLI (Command Line Interface) that we call Prowler Open Source and a service on top of it that we call Prowler Cloud.

Prowler App

Prowler App is a web application that allows you to run Prowler in your cloud provider accounts and visualize the results in a user-friendly interface.

📐✏️ High level architecture

Prowler App

The Prowler App consists of three main components:

• Prowler UI: A user-friendly web interface for running Prowler and viewing results, powered by Next.js.
• Prowler API: The backend API that executes Prowler scans and stores the results, built with Django REST Framework.
• Prowler SDK: A Python SDK that integrates with the Prowler CLI for advanced functionality.

Prowler CLI

You can run Prowler from your workstation, a Kubernetes Job, a Google Compute Engine, an Azure VM, an EC2 instance, Fargate or any other container, CloudShell and many more.

Deprecations from v3

General

• Allowlist now is called Mutelist.
• The --quiet option has been deprecated, now use the --status flag to select the finding's status you want to get from PASS, FAIL or MANUAL.
• All INFO finding's status has changed to MANUAL.
• The CSV output format is common for all the providers.

We have deprecated some of our outputs formats:

• The native JSON is replaced for the JSON OCSF v1.1.0, common for all the providers.

AWS

• Deprecate the AWS flag --sts-endpoint-region since we use AWS STS regional tokens.
• To send only FAILS to AWS Security Hub, now use either --send-sh-only-fails or --security-hub --status FAIL.
