As the need for secure cloud technology and services continues to rise, it has become increasingly important for businesses to understand cloud security concerns and the importance of best practices for mitigating them. For organizations adopting a Kubernetes-based cloud platform, understanding and addressing security challenges is mandatory to ensure optimal system levels of security.

At Ikaroa, we understand the need for secure cloud operations and have identified 14 security challenges associated with Kubernetes and cloud operations, and how to effectively solve them.

1. Network Access Control: Given the need for a secure connection between services and the chance for misconfigurations to open up a vulnerability in the network, monitoring and controlling the flow of data within the network is key. Organizations should plan for a comprehensive network access control policy that prescribes which types of communication are allowed and blocked.

2. Vulnerability Disclosure: It is important for organizations to be proactive in identifying and patching any potential vulnerabilities in their Kubernetes deployments. A vulnerability disclosure process should be established to encourage external feedback and help stay ahead of potential threats.

3. Resource Abuse and Sprawl: The ability to spin up Kubernetes resources quickly can be a great asset, however, it can also lead to unmanaged and wildly proliferating resources known as “sprawl”. Implementing resource quotas and proper governance helps to ensure that sprawl does not jeopardize the security of the environment.

4. Inadequate Logging and Monitoring: Without proper detection, logging, and monitoring of Kubernetes resources, it is impossible to track and audit activities that take place or detect threats in real-time. Organizations must invest in the setup of logging and monitoring processes to maintain granular visibility.

5. Application Secrecy: Application secrecy should not be overlooked when adopting a Kubernetes platform. Files and configurations should be kept confidential and encrypted and access should be restricted to only trusted servers and resources.

6. Poor Label Management: Kubernetes clusters and namespaces should be correctly labeled to ensure precise monitoring and control of all the cluster’s components and resources. Poor label management can cause problems in visibility and access and potentially lead to breaches.

7. Insufficient Configuration Security: Cloud security focuses on properly configuring the system as well as runtime environments. With Kubernetes, default settings or poorly configured settings can lead to process-level security issues. Organizations must invest in proper education and authorization processes to ensure secure configuration.

8. Improper Role Permissions: Role-level security must be implemented to ensure that the right people have the right and limited access to cluster and container resources. Improper permissions can lead to breaches of confidential information and roles should be regularly reviewed and audited.

9. Pruning of Egress and Ingress Routes: To restrict malicious actors from infiltrating the network, organizations need to ensure that all egress and ingress routes are properly pruned and monitored. The egress/ingress paths to the Kubernetes cluster should be set up only as per need and should be securely closed otherwise.

10. Container Image Pre-Scanning: Before running, the validity of all container images should be checked. Images should be checked against vulnerabilities, anomalous behaviors and malicious content. Pre-scanning can be implemented as part of a CI/CD process to reduce the risk of malicious intrusions.

11. High Availability and Scalability Capacity Planning: Capacity planning must be implemented when deploying a Kubernetes cluster. Organizations should plan for high availability and scalability to ensure that data is always available and not misplaced due to a catastrophic event or excessive workload.

12. Incorrect Kubernetes Settings: There are various settings within Kubernetes that can impact security. Setting up of profiles, users, and roles, configuring nodes and networks, and ensuring secure token management should all be thoroughly addressed and tested to ensure security.

13. 3rd Party Access: Security issues may arise due to third-party access. Passwords, SSH keys, tokens, and other credentials should be regularly updated, tracked, and revoked when appropriate. A rigorous authorization process should be in place to keep malicious actors away.

14. Lack of Automation: Automation is a key element of successful Kubernetes project implementations. Automating periodic tasks, upgrades, and scaling can improve security levels, as well as simplify and speed up day-to-day operations.

At Ikaroa, we understand that knowledge of security challenges and best practices are key to the effective rollout and management of any Kubernetes deployment. For further information on Kubernetes and cloud security, or to see our wide range of IT services, please visit our website at
