Are your container and Docker image secure?
Hackers have gone very active in the past few years.
Even big organizations like Facebook, Google, and Yahoo have been victims to attacks losing millions of dollars.
That is why an applications security is the utmost important thing in every organization today.
So, the security factor of these containers is very crucial.
The smaller container images have a lesser chance to get exposed to potential vulnerabilities.
Hence, it is crucial to scan and audit the images and containers regularly.
Lets explore the available options.
It is an API-driven analysis engine that checks for security flaws in the containers layer by layer.
It notifies you about a potential threat in the container.
Clair features:
Anchore
Anchoreis an open-source project for deep analysis of docker images.
It also certifies a docker image telling whether it is secured or not.
Anchore is also available in Jenkins plugins to scan the CI/CD pipeline.
If you just need a Kubernetes scanner then check out these tools tofind security flaws in Kubernetes.
you’ve got the option to use your custom security policy also to evaluate an image in anchore.
you’re able to access anchore engine through CLI or REST APIs.
in docker images and containers.
It uses the ClamAV antivirus engine to detect such vulnerabilities.
Then corresponding to the imported vulnerabilities, the images and containers are analyzed.
Dagda features:
Falco
Falcois an open-source project and a threat detection engine for Kubernetes.
It is a runtime security tool to detect anomalous activity in hosts and containers running on Kubernetes.
It detects any unexpected behaviors in your program and alerts you about the threats at runtime.
The rules focus on system calls and what system calls are allowed and disallowed on the system.
Aqua Security
Aqua Securityprotects applications that are built using cloud-native technologies like containers.
It provides vulnerability scanning and management for orchestrators like Kubernetes.
As developers build images, they have a set of technologies and libraries to build their images.
To run docker bench security, you’re gonna wanna have Docker 1.13.0 or later.
you’re gonna wanna trigger the below command to run docker bench security.
After this, the script will run, and it will share details forINFO,WARN,PASS.
It stores, signs, and scans docker images for vulnerabilities.
It can be installed on a Kubernetes cluster or any other system which supports Docker.
Harbor features:
JFrog Xray
JFrog Xrayis continuous open-source security and universal artifact analysis tool.
As a universal artifact analysis solution, Xray proactively identifies security vulnerabilities and license risks.
It scans for vulnerabilities inside images or containers in the DevOps pipeline and deployments on cloud or on-premise environments.
It gives you a view of images and containers running in the environment.
If you want to scan them, you’re gonna wanna take their paid subscription.
It also provides runtime security for containers by giving function levelfirewallfor containers.
you’re free to rundocker scanfrom Docker Desktop.
Grype
These days, container security is a popular topic.
It can be found onGitHuband is open source.
Both a web utility and a command-line tool are available for Grype.
It checks running containers for potential security flaws and scans public and private Docker images for vulnerabilities.
Since there are numerous ways to attack a container, having a solid security scanner is essential.
Conclusion
Now you know container security scanner does exist, so no excuse.
Go ahead and venture to see how they can help you keep yourcontainerized applicationsafe and secure.
