Top Container Vulnerability Scanning Tools

Spread the Knowledge

Trivy

Scanner for vulnerabilities in container images, file systems, and Git repositories, as well as for configuration issues and hard-coded secrets

Trivy (tri pronounced like trigger, vy pronounced like envy) is a simple and comprehensive scanner for vulnerabilities in container images, file systems, and Git repositories, as well as for configuration issues. Trivy detects vulnerabilities of OS packages (Alpine, RHEL, CentOS, etc.) and language-specific packages (Bundler, Composer, npm, yarn, etc.). In addition, Trivy scans Infrastructure as Code (IaC) files such as Terraform, Dockerfile and Kubernetes, to detect potential configuration issues that expose your deployments to the risk of attack. Trivy also scans hardcoded secrets like passwords, API keys and tokens. Trivy is easy to use. Just install the binary and you’re ready to scan.

Clair

Vulnerability Static Analysis for Containers.
Clair is an open source project for the static analysis of vulnerabilities in application containers (currently including OCI and docker).

Clients use the Clair API to index their container images and can then match it against known vulnerabilities.

Our goal is to enable a more transparent view of the security of container-based infrastructure. Thus, the project was named Clair after the French term which translates to clear, bright, transparent.

Anchore

A service that analyzes docker images and applies user-defined acceptance policies to allow automated container image validation and certification
The Anchore Engine is an open-source project that provides a centralized service for inspection, analysis, and certification of container images. The Anchore Engine is provided as a Docker container image that can be run standalone or within an orchestration platform such as Kubernetes, Docker Swarm, Rancher, Amazon ECS, and other container orchestration platforms.

In addition, we also have several modular container tools that can be run standalone or integrated into automated workflows such as CI/CD pipelines.

Syft: a CLI tool and library for generating a Software Bill of Materials (SBOM) from container images and filesystems

Grype: a vulnerability scanner for container images and filesystems

The Anchore Engine can be accessed directly through a RESTful API or via the Anchore CLI.

With a deployment of Anchore Engine running in your environment, container images are downloaded and analyzed from Docker V2 compatible container registries and then evaluated against user-customizable policies to perform security, compliance, and best practices enforcement checks.

Dagda

a tool to perform static analysis of known vulnerabilities, trojans, viruses, malware & other malicious threats in docker images/containers and to monitor the docker daemon and running docker containers for detecting anomalous activities
Dagda is a tool to perform static analysis of known vulnerabilities, trojans, viruses, malware & other malicious threats in docker images/containers and to monitor the docker daemon and running docker containers for detecting anomalous activities.

In order to fulfill its mission, first the known vulnerabilities as CVEs (Common Vulnerabilities and Exposures), BIDs (Bugtraq IDs), RHSAs (Red Hat Security Advisories) and RHBAs (Red Hat Bug Advisories), and the known exploits from Offensive Security database are imported into a MongoDB to facilitate the search of these vulnerabilities and exploits when your analysis are in progress.

Then, when you run a static analysis of known vulnerabilities, Dagda retrieves information about the software installed into your docker image, such as the OS packages and the dependencies of the programming languages, and verifies for each product and its version if it is free of vulnerabilities against the previously stored information into the MongoDB. Also, Dagda uses ClamAV as antivirus engine for detecting trojans, viruses, malware & other malicious threats included within the docker images/containers.

Falco

Cloud Native Runtime Security

The Falco Project, originally created by Sysdig, is an incubating CNCF open source cloud native runtime security tool. Falco makes it easy to consume kernel events, and enrich those events with information from Kubernetes and the rest of the cloud native stack. Falco can also be extended to other data sources by using plugins. Falco has a rich set of security rules specifically built for Kubernetes, Linux, and cloud-native. If a rule is violated in a system, Falco will send an alert notifying the user of the violation and its severity.

What can Falco detect?
Falco can detect and alert on any behavior that involves making Linux system calls. Falco alerts can be triggered by the use of specific system calls, their arguments, and by properties of the calling process. For example, Falco can easily detect incidents including but not limited to:

  • A shell is running inside a container or pod in Kubernetes.
  • A container is running in privileged mode, or is mounting a sensitive path, such as /proc, from the host.
  • A server process is spawning a child process of an unexpected type.
  • Unexpected read of a sensitive file, such as /etc/shadow.
  • A non-device file is written to /dev.
  • A standard system binary, such as ls, is making an outbound network connection.
  • A privileged pod is started in a Kubernetes cluster.

Aqua Security

The Aqua Cloud Native Security Platform provides prevention, detection, and response automation across the entire application lifecycle to secure the build, secure cloud infrastructure and secure running workloads wherever they are deployed.

Aqua scans artifacts for vulnerabilities, malware, secrets and other risks during development and staging. It allows you to set flexible, dynamic policies to control deployment into your runtime environments.

Automate compliance and security posture of your public cloud IaaS and Kubernetes infrastructure according to best practices.

Aqua checks your cloud services, Infrastructure-as-Code templates, and Kubernetes setup against best practices and standards, to ensure the infrastructure you run your applications on is securely configured and in compliance.

Protect VM, container and serverless workloads using granular controls with instant visibility and real-time detection and response.

Docker Bench

The Docker Bench for Security is a script that checks for dozens of common best-practices around deploying Docker containers in production.
The Docker Bench for Security is a script that checks for dozens of common best-practices around deploying Docker containers in production. The tests are all automated, and are based on the CIS Docker Benchmark v1.4.0.

Harbor

Harbor is an open source registry that secures artifacts with policies and role-based access control, ensures images are scanned and free from vulnerabilities, and signs images as trusted. Harbor, a CNCF Graduated project, delivers compliance, performance, and interoperability to help you consistently and securely manage artifacts across cloud native compute platforms like Kubernetes and Docker.

Qualys

Qualys, Inc. provides cloud security, compliance and related services and is based in Foster City, California. Qualys provides vulnerability management solutions using a “software as a service” model. It has added cloud-based compliance and web application security offerings

Docker Scan

Vulnerability scanning for Docker local images allows developers and development teams to review the security state of the container images and take actions to fix issues identified during the scan, resulting in more secure deployments. Docker Scan runs on Snyk engine, providing users with visibility into the security posture of their local Dockerfiles and local images.

Users trigger vulnerability scans through the CLI, and use the CLI to view the scan results. The scan results contain a list of Common Vulnerabilities and Exposures (CVEs), the sources, such as OS packages and libraries, versions in which they were introduced, and a recommended fixed version (if available) to remediate the CVEs discovered.

Cilium

Cilium is an open source software for providing, securing and observing network connectivity between container workloads – cloud native, and fueled by the revolutionary Kernel technology eBPF.

Dockle

Container Image Linter for Security, Helping build the Best-Practice Docker Image, Easy to start

Hadolint

Dockerfile linter, validate inline bash, written in Haskell. A smarter Dockerfile linter that helps you build best practice Docker images. The linter parses the Dockerfile into an AST and performs rules on top of the AST. It stands on the shoulders of ShellCheck to lint the Bash code inside RUN instructions.

Notary

Notary is a project that allows anyone to have trust over arbitrary collections of data

The Notary project comprises a server and a client for running and interacting with trusted collections. See the service architecture documentation for more information.

Notary aims to make the internet more secure by making it easy for people to publish and verify content. We often rely on TLS to secure our communications with a web server, which is inherently flawed, as any compromise of the server enables malicious content to be substituted for the legitimate content.

With Notary, publishers can sign their content offline using keys kept highly secure. Once the publisher is ready to make the content available, they can push their signed trusted collection to a Notary Server.

Consumers, having acquired the publisher’s public key through a secure channel, can then communicate with any Notary server or (insecure) mirror, relying only on the publisher’s key to determine the validity and integrity of the received content.

Grafeas

Building software at scale requires strong governance of the software supply chain, and strong governance requires good data. Today, Google, along with JFrog, Red Hat, IBM, Black Duck, Twistlock, Aqua Security and CoreOS, is pleased to announce Grafeas, an open source initiative to define a uniform way for auditing and governing the modern software supply chain. Grafeas (“scribe” in Greek) provides organizations with a central source of truth for tracking and enforcing policies across an ever growing set of software development teams and pipelines. Build, auditing and compliance tools can use the Grafeas API to store, query and retrieve comprehensive metadata on software components of all kinds.

As part of Grafeas, Google is also introducing Kritis, a Kubernetes policy engine that helps customers enforce more secure software supply chain policies. Kritis (“judge” in Greek) enables organizations to do real-time enforcement of container properties at deploy time for Kubernetes clusters based on attestations of container image properties (e.g., build provenance and test status) stored in Grafeas.

Grafeas (“scribe” in Greek) is an open-source artifact metadata API that provides a uniform way to audit and govern your software supply chain. Grafeas defines an API spec for managing metadata about software resources, such as container images, Virtual Machine (VM) images, JAR files, and scripts. You can use Grafeas to define and aggregate information about your project’s components. Grafeas provides organizations with a central source of truth for tracking and enforcing policies across an ever growing set of software development teams and pipelines. Build, auditing, and compliance tools can use the Grafeas API to store, query, and retrieve comprehensive metadata on software components of all kinds.

Grafeas divides the metadata information into notes and occurrences. Notes are high-level descriptions of particular types of metadata. Occurrences are instantiations of notes, which describe how and when a given note occurs on the resource associated with the occurrence. This division allows third-party metadata providers to create and manage metadata on behalf of many customers. It also allows for fine-grained access control of different types of metadata.
