Topic 6: Securing Containers, Kubernetes & Data

Strengthening Cloud‑Native Environments from Build to Runtime

Containers and Kubernetes have reshaped how modern teams build, deploy, and scale applications. Their flexibility and speed have enabled organisations to accelerate innovation—but they’ve also introduced new layers of complexity, new attack surfaces, and new operational risks.

Misconfigurations, runtime drift, overly permissive access, and unprotected data flows can leave cloud‑native environments exposed long before teams realise there is an issue. Our Securing Containers, Kubernetes & Data topic page explores these challenges in depth and outlines the modern security practices required to protect workloads from initial build to live production systems.

The Problem Domain

While Kubernetes and containerisation offer powerful orchestration and scalability, they also multiply potential weak points across clusters, images, networks, and data paths. Common challenges include:

• Misconfigured Kubernetes clusters, workloads, and components
• Risks introduced by container images, registries, and unmanaged dependencies
• Limited visibility across pods, namespaces, workloads, and network paths
• Inadequate runtime protection, enabling threats to go undetected
• Data exposure due to insufficient encryption or unsecured movement at rest or in transit
• Distributed, complex architectures that make consistent enforcement difficult

Left unaddressed, these issues can lead to compromised workloads, lateral movement, data leakage, and compliance breakdowns across cloud‑native environments.

The Solution Space

To meet these challenges, organisations are adopting a layered, lifecycle‑driven approach to securing containers and Kubernetes. Key practices include:

• Image scanning and supply chain controls to detect vulnerabilities before deployment
• Kubernetes posture management to identify and remediate misconfigurations early
• Runtime protection to detect suspicious or malicious behaviour in live environments
• Network visibility and micro‑segmentation to limit lateral movement and reduce blast radius
• Data security and encryption for all cloud and containerised workloads
• Continuous monitoring aligned with modern DevSecOps patterns to ensure sustained protection

These capabilities work together to secure the full container lifecycle—from build, to ship, to runtime—while giving teams actionable insight and control.

Our topic page also highlights trusted vendor solutions designed to support these capabilities and help organisations secure workloads, clusters, pipelines, and data end‑to‑end.

Recommended Vendors

We highlight leading solutions that support strong, scalable container and Kubernetes security:

• Docker
• Sysdig
• Mirantis

These vendors provide essential capabilities across image security, runtime protection, threat detection, Kubernetes posture management, and secure orchestration.
