Docker Security
Containers are now an integral part of modern DevOps and cloud environments. However, their lightweight nature and flexibility also harbor risks. With our Docker Security Testing, we comprehensively test your container infrastructure – from the image and the registry to the host.
Docker has established itself as a standard technology: containers are atomic, isolated, reproducible, and task-oriented. These properties make them attractive – but also vulnerable if security aspects are neglected.
Unlike classic virtualization technologies, the security of a Docker system depends not only on the container itself, but also on images, registry, runtime, and the configuration of the host. Vulnerabilities in just one of these levels can be enough to give attackers access. A holistic test is therefore essential.
Our Services
We offer you a complete security analysis of your Docker environment, tailored to your infrastructure and your application context. In particular, we examine:
- Docker Images: Testing for known vulnerabilities, unauthorized components, and accidentally included secrets.
- Docker Registry: Analysis of storage locations and access controls for container images.
- Runtime & Container Configuration: Evaluation of security settings during operation.
- Docker Host & Configuration: Investigation of the hardening of the host and the general Docker configuration.
Our analyses are based on established standards such as the CIS Docker Benchmark and the NIST Application Container Security Guide.
Our approach is practical and standard-based to cover both technical details and organizational aspects:
- Scoping & Planning: Definition of the images, containers, and environments to be tested.
- Image Analysis: Examination for vulnerabilities, dependencies, and secrets.
- Registry Check: Verification of security and access controls.
- Runtime Tests: Analysis of running containers for misconfigurations and insecure settings.
- Host Review: Assessment of the hardening and security-relevant parameters of the Docker host.
- Reporting: Documentation of all results with clearly prioritized recommendations for action.
Checkpoints
To ensure that no security-critical vulnerability remains undiscovered, we focus on:
- Vulnerabilities in Docker images and used libraries
- Security of the Docker Registry and access rights
- Configuration of runtime environments (Capabilities, Isolation, Networking)
- Securing the Docker host and operating system
- Compliance with recognized benchmarks (CIS, NIST)
- Management of secrets and sensitive data
