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).

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

In order to just build and run the Clouditor, without generating the protobuf file, one can use the run-engine-with-ui.sh script. This still requires Go and Node.js to be installed. For example, to run the engine in-memory with the Azure provider the following command can be used:

./run-engine-with-ui.sh --discovery-provider=azure

This will start the all-in-on-engine with all discoverers enabled and launches the UI on http://localhost:3000. The default credentials are clouditor/clouditor.

Next to the regular cloud provider discoverers, Clouditor also comes with a a set of extra discoverers for dedicated protocols, for example CSAF. The CSAF discoverer allows the conformance check of a CSAF (trusted) provider.

It can be used with the following command:

./run-engine-with-ui.sh --discovery-provider=csaf --discovery-csaf-domain=clouditor.io

The domain clouditor.io can be replace with your actual domain.

Install necessary protobuf tools, including buf. Please refer to the buf install guide.

go install github.com/srikrsna/protoc-gen-gotag \
github.com/oxisto/owl2proto/cmd/owl2proto

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

go generate ./...
go build -o ./engine cmd/engine/engine.go

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

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>

The CLI can also be used to interact with the experimental resource graph, for example to add additional information about an application and its dependencies:

cl service discovery experimental update-resource \
'{"id": "log4j", "targetOfEvaluationId": "00000000-0000-0000-0000-000000000000", "resourceType": "Library,Resource", "properties":{"name": "log4j", "groupId": "org.apache.logging.log4j", "artifactId": "log4j-core", "version": "2.17.0", "dependencyType": "maven", "url": "https://github.com/apache/logging-log4j2", "vulnerabilities": ["CVE-2021-44832"]}}'
cl service discovery experimental update-resource \
'{"id": "Main.java", "targetOfEvaluationId": "00000000-0000-0000-0000-000000000000", "resourceType": "TranslationUnitDeclaration,Resource", "properties":{"name": "Main.java", "code": "class Main { public static void main(String[] args) { return; } }"}}'
cl service discovery experimental update-resource \
'{"id": "MyApplication", "targetOfEvaluationId": "00000000-0000-0000-0000-000000000000", "resourceType": "Application,Resource", "properties":{"@type":"type.googleapis.com/confirmate.ontology.v1.Application", "id:": "MyApplication", "name": "MyApplication","dependencies":["log4j"],"translationUnits":["Main.java"]}}'
cl service discovery experimental update-resource \
'{"id": "github.com/org/app", "targetOfEvaluationId": "00000000-0000-0000-0000-000000000000", "resourceType": "CodeRepository,Resource", "properties":{"id:": "github.com/org/app", "name": "github.com/org/app", "parent": "MyApplication", "url": "github.com/org/app"}}'

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.
