OWASP Kubernetes Top Ten – K08: Secrets Management Failures

2 May 2025 by Krishna

In the fast-evolving world of cloud-native applications, Kubernetes has emerged as the de facto standard for container orchestration. While its robust architecture streamlines deployment, scaling, and management of applications, Kubernetes introduces a unique set of security challenges. Among these, secrets management failures pose a significant risk, often leading to data breaches, unauthorised access, and compliance violations.
The OWASP Kubernetes Top Ten (K8s Top 10) highlights the most critical security risks in Kubernetes environments. K08: Secrets Management Failures underscores the common pitfalls software developers and software architects encounter when handling sensitive data such as API keys, credentials, and encryption keys.

OWASP Kubernetes Top Ten – K07: Missing Network Segmentation Controls

1 May 2025 by Krishna

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 – K06: Broken Authentication Mechanisms

30 April 2025 by Krishna

Kubernetes has become the backbone of modern cloud-native infrastructure, enabling organisations to deploy, manage, and scale containerised applications efficiently. However, this technological advancement brings forth a host of security challenges, particularly in authentication and access control. Among the OWASP Kubernetes Top Ten security risks, K06: Broken Authentication Mechanisms stands out as a critical vulnerability that can lead to unauthorised access, privilege escalation, and data breaches.

OWASP Kubernetes Top Ten – K05: Inadequate Logging and Monitoring

29 April 2025 by Krishna

Kubernetes is a dynamic, distributed system that orchestrates containerised applications at scale. Given its complexity, logging and monitoring are essential for:

Security Incident Detection: Identifying unauthorised access, suspicious activity, or potential breaches.

Performance Optimisation: Detecting bottlenecks, resource exhaustion, or application failures.

Compliance and Auditability: Meeting regulatory requirements such as GDPR, ISO 27001, and SOC 2.

Operational Stability: Ensuring smooth functioning of services, reducing downtime, and proactively resolving issues.

OWASP Kubernetes Top Ten – K04: Lack of Centralised Policy Enforcement

28 April 2025 by Krishna

Kubernetes has become the de facto standard for orchestrating containerised applications, offering immense scalability, automation, and resilience. However, its complexity also introduces a broad attack surface. The OWASP Kubernetes Top Ten identifies the most pressing security risks, and K04: Lack of Centralised Policy Enforcement is among the most critical. Without a unified approach to security policies, organisations risk misconfigurations, compliance failures, and security breaches.
