While Kubernetes adoption continues to soar, it has become a prime target for cyberattacks. Unfortunately, Kubernetes clusters are complex and can be difficult to secure. Safeguarding your Kubernetes environment requires a solid understanding of the common attack chains that pose a threat to your infrastructure. In this blog post, we dig into the top attack chains that target Kubernetes, shedding light on the risks and offering valuable insights to bolster your defenses.

The timeline of an application can be broadly described in 3 phases: Thus, runtime security in the context of a cloud-native container environment broadly refers to the tools and processes leveraged to protect the operation of running containers in production.

Containers offer a streamlined application deployment and management approach. Thanks to their efficiency and portability, platforms like Docker and Kubernetes have become household names in the tech industry. However, a misconception lurks in the shadows as containers gain popularity - the belief that active vulnerability scanning becomes redundant once containers are implemented.

In my previous blog post, What you can’t do with Kubernetes network policies (unless you use Calico): TLS Encryption, I talked about use case number two from the list of 9 things you cannot implement using basic Kubernetes network policy—anything TLS related. In this blog post, we’ll be focusing on use case number three: node specific policies.

According to research done by ARMO, 100% of Kubernetes clusters that were tested contained at least one misconfiguration, while 65% had at least one high-severity misconfiguration. 50% of clusters had 14 or more failed security controls. According to Redhat research from 2023, 45% of respondents experienced security incidents or issues related to containers and/or Kubernetes due to misconfigurations.

Three security issues were reported on October 27th by the Kubernetes security community, all of them related to the popular NGINX ingress component.

In today’s rapidly evolving digital landscape, containerized microservices have become the lifeblood of application development and deployment. Resembling miniature virtual machines, these entities enable efficient code execution in any environment, be it an on-premises server, a public cloud, or even a laptop. This paradigm eliminates the criteria of platform compatibility and library dependency from the DevOps equation.

“What’s New in Sysdig” is back with the October 2023 edition! My name is Zain Ghani, based in Austin, Texas, joined by my colleague, Matt Baran, based in Los Angeles, California, to share our latest updates with you. The last few weeks have been really exciting at Sysdig.
