An Brief Introduction On Container Security Scanning & Their Tools

What is Docker Security Scanning?

[Container Security Scanning]….All services that you require inside a container Docker permits you to install all this, you are free from all the worries about installing on a similar package with several versions on your system. You can use Docker to operate services and applications and it has its sandboxes which are known as containers. With the help of a Docker, you can easily dispense the whole environment of an application from one to another. The process to find out the presumed security in the package listed in your Docker image. Docker image security plays a very important role in terms of Docker security. If we have to generate a Docker image then firstly we have to generate a Dockerfile and by utilizing the Docker build command you can turn it into an image after finishing Dockfile.[Container Security Scanning]

Container/ Docker Security Scanning Tools

These tools are important to find out for identifying vulnerabilities in container images. These tools examine container images for known vulnerabilities, compliance issues and misconfigurations. Now we will explain some of the tools are as follow:

♥ Docker Bench

It is utilized in the production to search numerous best practices and the automated tests for checking the best practices around Docker containers and it works like a script. Docker Bench focuses on developers because it regulates containers with the community edition of Docker. You have to require Docker 1.13.0 to operate Docker Bench. It’s an open-source script that checks for best practices in Docker deployments. This tool is created to automate security check , support to making sure that Docker host and container attach to the best security practices as outlined by Docker’s security guidelines.

♥ Clair

It is an open-source project which is utilized in Quay.io that has an alternative to Docker Hub and it is also a public container registry that is created by CoreOS. It proposes security for applications and dockers and by using Clair you can create services that continuously regulate your container for any susceptibility of the container. Every data is recorded in NVD, which means National Vulnerability Database, so in a case where any error recognizes them, it will procure the circumstances and furnish every detail in the report.

♥ Anchore

For scanning, the CI/CD pipeline Anchore is obtainable in Jenkins Plugins and it can operate on orchestration and standalone platforms like Rancher, Kubernetes, Docker Swarm and Amazon ECS. One of the important features of Anchore is to permit the users to execute the intense container image exploration to check  the package of the operating system, RubyGEMs and Node.JS modules as well every single file is coated in the analysis.

♥ OpenSCAP

This is one of the best tools that is used by security auditors and IT admins that consists of open source tools, configuration baselines and open security benchmark guides. It also uses SCAP which means Security Content Automation Protocol which is NIST -certified that furnishes the security policies and that is readable to machines. In comparison with others, OpenSCAP is more broad-based than others.

♥ Dagda

It’s an open-source tool that is used for static analysis of container security and also for scanning viruses, vulnerabilities, malware and viruses in Docker containers. If you want to use Dagda then firstly you have to scan the Docker container. It stored the vulnerability data as well. It is very flexible that handles both REST API as well CLI and that is one of the important benefits of Dagda and for the detection of vulnerability, it operates an antivirus engine named ClamAV.

♥ Black Duck OpsSight

It is also an open-source vulnerability that observes and accentuates any of the images which consist of open source vulnerabilities. In case of any differences, Black Duck OpsSight noticed and attended within the orchestration platforms. One of the important features of OpsSight is its standard container images that have a security policy that is open source.

♥ Sysdig Falco

Sysdig Falco tool is formulated by Sysdig to recognize some bizarre action in your application which is an open-source tool as well and that is created for Kubernetes, cloud environment and containers. It also regulates and recognizes host, network activity, container and application. It constantly monitors and discovered unpredicted behavior, vulnerabilities, intrusions in actual time. It combine with several Kubernetes environments, SIEM tools and CI/Cd pipelines.

♥ Dockle

It’s an open-source tool that is very useful for ascertaining that the best practices for writing Dockerfiles chase Docker drawbacks. You can also use Dockle to lint container images in opposition to user exemption escalation, CIS benchmarks, potentially vulnerable commands and assisting to ignore sensitive mysteries. With the help of other platforms like Mac OS X, Linux and Homebrew you can easily install Dockle.

♥ Trivia

It is formulated to be used within the process of CI and CD and to deploy an application or previously delivered to a container to scan for vulnerabilities. In the other word you can say for any container, it’s a vulnerability scanner. This is a complete security scanning tool that is created by Aqua Security and it is utilized for identifying vulnerabilities in file system, container images, & Git repositories. It scan the container images for vulnerabilities in some of the OS package as like RHEL, Debian etc.

♥ Hadolint

This tool is written in Haskell that is operated by a small firm or a team and it also supports the team’s for their structure or in other ways team structure and deploys Docker containers best practices and it works as a linter also.
