Clouditor Community Edition

Introduction

Clouditor is a tool which supports continuous cloud assurance. Its main goal is to continuously evaluate if a cloud-based application (built using, e.g., Amazon Web Services (AWS) or Microsoft Azure) is configured in a secure way and thus complies with security requirements defined by, e.g., Cloud Computing Compliance Controls Catalogue (C5) issued by the German Office for Information Security (BSI) or the Cloud Control Matrix (CCM) published by the Cloud Security Alliance (CSA).

Features

Clouditor currently supports over 60 checks for Amazon Web Services (AWS), Microsoft Azure and OpenStack. Results of these checks are evaluated against security requirements of the BSI C5 and CSA CCM.

Key features are:

• automated compliance rules for AWS and MS Azure
• granular report of detected non-compliant configurations
• quick and adaptive integration with existing service through automated service discovery
• descriptive development of custom rules using Cloud Compliance Language (CCL) to support individual evaluation scenarios
• integration of custom security requirements and mapping to rules

Usage

To run the Clouditor in a demo-like mode, with no persisted database:

docker run -p 9999:9999 clouditor/clouditor

To enable auto-discovery for AWS or Azure credentials stored in your home folder, you can use:

docker run -v $HOME/.aws:/root/.aws -v $HOME/.azure:/root/.azure -p 9999:9999 clouditor/clouditor

Then open a web browser at http://localhost:9999. Login with user clouditor and the default password clouditor.

Development

Code Style

We use Google Java Style as a formatting. Please install the appropriate plugin for your IDE.

Git Hooks

You can use the hook in style/pre-commit to check for formatting errors:

cp style/pre-commit .git/hooks

Build (gradle)

To build the Clouditor, you can use the following gradle commands:

./gradlew clean build

Build (Docker)

To build all necessary docker images, run the following command:

./gradlew docker

Build (Go components) - Experimental

Install necessary protobuf tools.

go install google.golang.org/protobuf/cmd/protoc-gen-go \
google.golang.org/grpc/cmd/protoc-gen-go-grpc \
github.com/grpc-ecosystem/grpc-gateway/v2/protoc-gen-grpc-gateway \
github.com/googleapis/gnostic/apps/protoc-gen-openapi

Also make sure that $HOME/go/bin is on your $PATH and build:

go generate ./...
go build ./...

To test, start the engine with an in-memory DB

./engine --db-in-memory

Alternatively, be sure to start a postgre DB:

docker run -e POSTGRES_HOST_AUTH_METHOD=trust -d -p 5432:5432 postgres 

Clouditor CLI

The Go components contain a basic CLI command called cl. It can be installed using go install cmd/cli/cl.go. Make sure that your ~/go/bin is within your $PATH. Afterwards the binary can be used to connect to a Clouditor instance.

cl login <host:grpcPort>

Command Completion

The CLI offers command completion for most shells using the cl completion command. Specific instructions to install the shell completions can be accessed using cl completion --help.
