The Payment Card Industry Data Security Standard (PCI DSS) is a global standard designed to ensure the security of cardholder information. It is crucial for any organization that stores, processes, or transmits payment card data to comply with PCI DSS to protect the integrity and confidentiality of cardholder information.

In today’s fast-paced cloud-native world, scaling security alongside rapid development cycles presents significant challenges. As organizations increasingly adopt Kubernetes, ensuring consistent, fine-grained security across dynamic workloads becomes essential. Calico’s policy model for microsegmentation offers a scalable solution that integrates seamlessly into DevSecOps workflows, enabling teams to implement robust security controls without compromising agility.

As Kubernetes and containerized environments become the backbone of modern application development, securing these environments grows increasingly complex. The distributed nature of microservices, the dynamic scaling of workloads and the ephemeral nature of containers introduce unique security challenges. Traditional approaches to risk assessment — where vulnerabilities, misconfigurations and threats are identified and prioritized in isolation — often fall short in such environments.

In the rapidly evolving world of container security, staying ahead of threats and keeping abreast of vulnerabilities is crucial. Calico Cloud continues to lead the way with new capabilities designed to enhance security posture, reduce noise, and improve operational efficiency for Security and DevOps teams. Here’s a comprehensive look at how these enhancements can impact your security posture and streamline your operations.

DNS policies play a critical role in managing and securing workload communication for cloud-native applications running on Kubernetes clusters. Two popular options for implementing DNS policies are Calico and Cilium. While both have their merits, Calico’s approach offers several distinct advantages over Cilium’s, particularly in terms of flexibility, scalability, and overall operational simplicity.

As companies build more cloud-native apps, securing them across different infrastructures becomes a challenge. Cloud-native apps leveraging different deployment environments such as on-premises, public cloud, or hybrid have different security challenges as they are scaling, interoperable, and cost-effective.

Today, most organizations and individuals use Linux and the Linux kernel with a “one-size-fits-all” approach. This differs from how Linux was used in the past–for example, 20 years ago, many users would compile their kernel and modify it to fit their specific needs, architectures and use cases. This is no longer the case, as one-size-fits-all has become good enough. But, like anything in life, “good enough” is not the best you can get.

Calico policies are a way to enforce network security at the pod level. This blog post will provide a comprehensive overview of Calico policies for Calico OS (Open Source) users. We will cover the basics of Calico policies, including what they are, how they work, and how to use them. We will also provide best practices for using Calico policies and examples of how they can be used in real-world scenarios.

Misconfigurations and container image vulnerabilities are major causes of Kubernetes threats and risks. According to Gartner, more than 90% of global organizations will be running containerized applications in production by 2027. This is a significant increase from fewer than 40% in 2021. As container adoption soars, Kubernetes remains the dominant container orchestration platform.

23andMe is a popular genetics testing company, which was valued at $6B in 2021. Unfortunately, there was a massive data breach in December 2023, which caused a steep decline in the company’s value and trust, plummeting the company to a penny stock. While this breach was not directly related to Kubernetes, the same risks apply to containers running in your Kubernetes environments.
