Kubernetes network security foundations: Get started on building your Kubernetes network security policies with Calico!
The adoption of cloud native applications has become a necessity for organizations to run their businesses efficiently. As per Gartner, more than 85% of organizations will embrace a cloud-first principle by 2025, which will rely on adopting cloud native applications for complete execution. The massive increase in adoption of cloud native applications has given rise to more security challenges such as container image vulnerabilities, configuration errors and a larger runtime attack surface. Kubernetes has become the de facto standard platform to host and run cloud native applications. However, as Kubernetes adoption gains momentum, so does the security risk associated with business-critical applications that communicate with multiple external and internal systems. Kubernetes network security is a critical aspect of securing cloud native applications and the Kubernetes platform itself. This multi-part blog series aims to explore the network security challenges of the Kubernetes environment and provide insights into mitigating them using Calico security controls. The series will cover various aspects of network security, including security policies, application layer security, host network security, Pod traffic encryption, and the importance of a defense-in-depth security approach. Let’s dive into the world of Kubernetes network security and learn how to protect your organization’s valuable assets.
