Kubernetes has become a cornerstone in modern IT environments, significantly revolutionizing the way applications are deployed and managed. Its ability to automate scaling, deployment, and management of containerized applications makes it indispensable for businesses aiming for agility, scalability, and efficiency. As organizations increasingly adopt microservices architectures, Kubernetes’ role in providing seamless orchestration and robust security continues to grow in importance.

93% of last year’s data breaches began with compromised credentials. Before the cloud, security perimeters were defined by physical walls and network boundaries, but in the cloud, that perimeter has all but dissolved. Consider what happened in November 2023, when a cloud observability vendor found evidence of unauthorized access to its staging environment — an environment that housed customer data and PII.

Cloud workloads — and containers in particular — are often seen as immutable entities with predictable behavior. But recent CrowdStrike research suggests that some cloud security solutions rely too much on this premise, leading to suboptimal detection outcomes. CrowdStrike observes billions of container events each day. The data we collect gives us insights into real-world cloud workload behavior, which challenges these assumptions.

At Indiana University, OpenInfra Days North America 2024 was an event that brought together the brilliant minds of the open infrastructure community. For my teammate Kevin Jackson and I, this was not just another tech event; it was a long-overdue reunion with friends in the OpenStack community and an exciting opportunity to forge new relationships. The atmosphere was charged with collaboration and learning, with best practices, user journeys, and insightful panel discussions taking center stage.

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.

This is the second episode of the CSI Container series, published and presented at CloudNativeSecurityCon 2024. In this episode, we focus on Kubernetes CSI, how to conduct DFIR activities on K8s and containers, and how to perform static and dynamic analysis. As we covered in the first episode, DFIR refers to the union of Digital Forensics (DF) and Incident Response (IR). We also highlighted how conducting DFIR activities in a container environment differs from the usual DFIR in a host environment.

We know that cloud attacks happen very quickly. Our 2024 global threat year-in-review, the third annual threat report from the Sysdig Threat Research Team (TRT), revisits the team’s hottest findings from the last 12 months and explores how they relate to the broader cyber threat landscape. This year’s report also includes informed predictions about 2025’s security outlook and potential trends.

Containers are transforming how enterprises deploy and use applications - their efficiency and cost-effectiveness making them a cornerstone of modern IT strategies. Compared to traditional virtualization, where the server runs a hypervisor, and then virtual machines with entire guest operating systems and software run on top of the hypervisor, containers allow more versatility since they simplify management and provide faster provisioning of applications and resources.

The dynamic world of Kubernetes and cloud security is constantly evolving. As we explore this complicated ecosystem, it’s crucial to understand the role of policy as code (PaC) and its impact on operations and security teams. Emerging from the broader paradigm of infrastructure as code (IaC), PaC represents a significant shift in how we manage and secure cloud-native environments.

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.
