Most container images are built using Dockerfiles which contain combinations of instructions like FROM, RUN, COPY, ENTRYPOINT, etc. to build the layers of an OCI-compliant image. One instruction that is used surprisingly rarely, though, is LABEL. In this post, we’ll dig into labels (“annotations” in the OCI Image Specification) what they are, some standardized uses as well as some practices you can use to enhance your container security posture.

In this blog post, I will be talking about label standard and best practices for Kubernetes security. This is a common area where I see organizations struggle to define the set of labels required to meet their security requirements. My advice is to always start with a hierarchical security design that is capable of achieving your enterprise security and compliance requirements, then define your label standard in alignment with your design.

Halloween is around the corner! 🎃 Imagine that you’re with your cloud-native friends, sitting around the fireplace, having some s’mores, and telling spooky stories. Here are our best spooky stories for the cloud community. Enjoy them, and have an awesome Halloween!

Discover what CIEM Security is and how easy it is to implement with Sysdig Secure for cloud. Over-permissioned accounts and roles is the most common cloud service misconfiguration security problem. Implementing least privilege is a crucial best practice to avoid or mitigate risks of data breaches and contain privilege escalation and lateral movement.

The Tsunami malware is back! Although it appeared for the first time several years ago, the Sysdig Research Team has just discovered a new sample of Tsunami malware targeting Jenkins and Weblogic services deployed in Kubernetes clusters. The Tsunami malware is a backdoor that gives the attackers full control over the infected systems. Indeed the targeted machines, once infected, communicate with an IRC server waiting for new commands to be executed.

On Oct 21st, the Kubernetes Security Response Committee issued an alert that a new high severity vulnerability was discovered in Kubernetes with respect to the ingress-nginx - CVE-2021-25742. The issue was reported by Mitch Hulscher. Through this vulnerability, a user who can create or update ingress objects, can use the custom snippets feature to obtain all secrets in the cluster.

Containers have changed how applications are developed and deployed, with Kubernetes ascending as the de facto means of orchestrating containers, speeding development, and increasing scalability. Modern application workloads with microservices and containers eventually need to communicate with other applications or services that reside on public or private clouds outside the Kubernetes cluster. However, securely controlling granular access between these environments continues to be a challenge.

The ISO 27001 certification can make a difference when your business is tied with deploying cloud-native applications. Providing relevance and credibility in front of potential customers will show that your company takes security seriously, ensuring the client’s trust. We previously covered other compliance frameworks in our blog, like GDPR, HIPAA, NIST, and SOC 2. Those frameworks also show a strong commitment to security best practices.
