Considerations of container security in the public cloud comprises several layers. It is crucial for organizations to understand the capabilities of the cloud service providers to gauge whether they can fulfil their compliance and security needs. Organizations are in dire need for resources that help them in continuous monitoring and management of their containers with a smooth control.

Implementation of container security involves proactive monitoring of events in real-time. This is to navigate, detect, and prevent any malicious activity, which is time-intensive without a robust process in place for analysis. Container security prevents system compromisations by securing applications and CI/CD pipelines while enabling improvements in security policies.

The Importance of Container Security

Containerization is an approach for facilitating the creation, deployment, and running of applications by consolidating dependencies, such as data files, into a single solution. On the other hand, containers do not comprise operating system images, which creates the need for orchestrating mediums, for example, Kubernetes. These orchestrators play the vital role of interacting with other system applications for the creation or distribution of containers. This further provides users with the authority to control these containers

Providing users with the authority, however, leads to the possibility of containers becoming a potential target for attackers. The cloud is evolving faster but so are the attackers. The level of sophistication in cyberattacks can render the whole cloud environment to be compromised, if security is improperly maintained. This has further led organizations to prioritize cloud API protection. 

Key Responsibilities of Container Security

Container security falls under the responsibility of organizations, following the shared responsibility paradigm. Key areas where protection is critical include runtime containers, container registries, and container images. In the case of a Kubernetes-based PaaS deployment, for example, security of the IaaS components, namely, storage, network, and compute, fall under the responsibility of the cloud service provider.

Organizations are responsible for the deployment, operations, and security of their applications. Key container security responsibilities of organizations include

Safeguarding Workloads Under Application Containers: It is important for organizations to come up with robust policies to secure activities that deflect from their normal behavior for preventing configuration glitches. The security policies of organizations must be on par with the dynamics of their applications. A strong management framework will help organizations estimate changes in applications, enabling the security team to work proactively for keeping applications from functioning improperly.

Managing Vulnerability: The belief that the process of identifying vulnerabilities must be carried out in the CI/CD phase is a misconception. It is critical for organizations that they focus on identifying vulnerabilities all through the lifecycle of containers, including container registries and runtime containers. Organizations must leverage skilled resources for the identification, analysis, and prioritization of vulnerabilities prior to their remediation. 

To Sum Up

The responsibility of organizations in container security grows as strong as their efforts in enforcing security measures. They must look to blend security best practices all throughout the lifecycle of containers. This will help them ensure the integrity and confidentiality of their applications’ sensitive information in the cloud.
