Sysdig’s seventh annual Cloud-Native Security and Usage Report identifies how customers are developing, using, and securing cloud-native applications and environments. We analyze data from millions of containers and thousands of accounts and publish the most pertinent information for you. Security practitioners and leaders look forward to this report to identify trends and make adjustments to their cloud security strategy.

Snyk has discovered a vulnerability in all versions of Docker Buildkit <=v0.12.4, as used by the Docker engine. The exploitation of this issue can result in container escape to the underlying host OS when building an image using a malicious Dockerfile or upstream image (i.e. when using FROM). This issue has been assigned CVE-2024-23651.

Snyk has discovered a vulnerability in all versions of runc <=1.1.11, as used by the Docker engine, along with other containerization technologies such as Kubernetes. Exploitation of this issue can result in container escape to the underlying host OS, either through executing a malicious image or building an image using a malicious Dockerfile or upstream image (i.e., when using FROM). This issue has been assigned the CVE-2024-21626.

Snyk security researcher Rory McNamara, with the Snyk Security Labs team, identified four vulnerabilities — dubbed "Leaky Vessels" — in core container infrastructure components that allow container escapes. An attacker could use these container escapes to gain unauthorized access to the underlying host operating system from within the container.

NXDOMAIN, indicating the non-existence of a queried domain, poses significant challenges within Kubernetes, impacting application functionality, service communication, and overall cluster stability. Investigating NXDOMAIN responses in Kubernetes is vital for sustaining the reliability, performance, and security in a containerized environment.

Happy New Year! My name is Zain Ghani. I’m a Customer Solutions Architect based in Austin, Texas, and I’m excited to share our latest updates with you. This year started with multiple recognitions for Sysdig. GigaOM named Sysdig a Leader and the only Outperformer in its inaugural Cloud Workload Security Radar report.

The cloud security market has been totally bizarre ever since it started. Why are we being given a python script to count our workloads? How do we handle sending alerts like “new unencrypted database” to a SOC? What’s the difference between this tool and the open source options? We’re all learning together about the new processes, tools, and deployments that would define the future.

This article uses Kubernetes Secrets as a native Kubernetes component for handling sensitive data at container runtime and Vault as a trusted storage and maintenance solution for sensitive data.

Public cloud infrastructure is, by now, the default approach to both spinning up a new venture from scratch and rapidly scaling your business. From a security perspective, this is a brand new (well, by now more than a decade old) attack surface. “Attack surface” is a commonly used term that denotes the aggregate of your exploitable IT estate, or all of the different pathways a hacker might be able to use to gain access to your systems, steal your data, or otherwise harm your business.
