Kubernetes is an open-source platform that provides developers and DevOps with an end-to-end security solution. This includes security compliance, risk analysis, security compliance and RBAC visualizer. It also scans images for vulnerabilities. Kubescape scans K8s clusters, Kubernetes manifest files (YAML files, and HELM charts), code repositories, container registries and images, detecting misconfigurations according to multiple frameworks (such as the NSA-CISA, MITRE ATT&CK®), finding software vulnerabilities, and showing RBAC (role-based-access-control) violations at early stages of the CI/CD pipeline. It instantly calculates risk scores and displays risk trends over time. Kubescape is one of the most popular Kubernetes security compliance tools for developers. Its easy-to-use interface, flexible output formats and automated scanning capabilities have made Kubescape one of the fastest growing Kubernetes tools. This has saved Kubernetes admins and users precious time, effort and resources.

Qualys Cloud Security offers a vulnerability analysis plug-in specifically designed for the CI/CD tool Jenkins, with plans to expand to additional platforms such as Bamboo, TeamCity, and CircleCI in the near future. Users can conveniently download these plug-ins straight from the container security module. This integration allows security teams to engage in the DevOps workflow, ensuring that vulnerable images are blocked from entering the system, while developers receive practical insights to address vulnerabilities effectively. It is possible to establish policies aimed at preventing the inclusion of vulnerable images in repositories, with settings adjustable based on factors like vulnerability severity and particular QIDs. The plug-in also provides an overview of the build, detailing vulnerabilities, information on software that can be patched, available fixed versions, and the specific image layers affected. Given that container infrastructure is inherently immutable, it is essential for containers to be consistent with the original images they are created from, thus necessitating rigorous security measures throughout the development lifecycle. By implementing these strategies, organizations can enhance their ability to maintain secure and compliant container environments.

DevSecOps operates at full throttle by thoroughly examining container images and implementing compliance based on established policies.

This advancement effectively ends the prevalence of container escapes, reduces the need for costly security tools, and alleviates the burden of endlessly sifting through logs. With just a few lines of YAML, you can launch Edera Protect and get started effortlessly. Designed in Rust to enhance memory safety, this solution has no negative impact on performance. It represents a secure-by-design Kubernetes framework that effectively neutralizes threats before they can take action, transforming the landscape of cloud-native security.

Clair is an open-source initiative designed for the static analysis of security vulnerabilities within application containers, such as those used in OCI and Docker environments. Users interact with the Clair API to catalog their container images, allowing them to identify any potential vulnerabilities by comparing them to established databases. The primary aim of this project is to foster a clearer understanding of the security landscape surrounding container-based infrastructures. Reflecting this mission, the name Clair is derived from the French word that means clear, bright, or transparent. Within Clair, manifests serve as the framework for representing container images, and the project utilizes the content-addressable nature of OCI Manifests and Layers to minimize redundant processing efforts, thereby enhancing efficiency in vulnerability detection. By streamlining this analysis, Clair contributes significantly to the overall security of containerized applications.
