OWASP Kubernetes Top Ten – K10: Outdated and Vulnerable Kubernetes Components

by

Kubernetes has become the de facto standard for container orchestration, offering scalability, flexibility, and automation for modern applications. However, as its adoption grows, so do the security risks associated with misconfigurations, outdated components, and unpatched vulnerabilities. The OWASP Kubernetes Top Ten (K10) highlights critical security issues within Kubernetes environments, and K10: Outdated and Vulnerable Kubernetes Components specifically addresses the risks of running obsolete or insecure Kubernetes elements.

OWASP Kubernetes Top Ten – K07: Missing Network Segmentation Controls

by

Kubernetes has become the de facto standard for container orchestration, empowering organisations to deploy, manage, and scale applications seamlessly. However, its flexibility comes with security challenges, and the OWASP Kubernetes Top Ten identifies the most critical risks organisations face. One such risk, K07: Missing Network Segmentation Controls, is a significant concern that can lead to lateral movement attacks, unauthorised access, and data breaches.
Network segmentation is the practice of logically or physically dividing a network into isolated segments to limit access and control data flow between different workloads. In Kubernetes, network segmentation ensures that different workloads, namespaces, and services only communicate when necessary, reducing attack surfaces and preventing lateral movement.

OWASP Kubernetes Top Ten – K03: Overly Permissive RBAC Configurations

by

Kubernetes has revolutionised container orchestration, enabling businesses to scale applications efficiently. However, with great power comes great responsibility, and security remains a crucial concern. One of the most pressing security issues highlighted in the OWASP Kubernetes Top Ten is K03: Overly Permissive RBAC Configurations. This vulnerability can lead to privilege escalation, unauthorised access, and severe security breaches.

Container Escapes: An Executive Guide to Mitigating Container Security Risks

by

A container escape occurs when an attacker exploits a security gap within the container to break out and access the host system. This escape can involve taking advantage of:

– Vulnerabilities in the containerisation software.
– Misconfigurations in permissions or settings.
– Insecure images that may contain malware or backdoors.
