Fargate offers a great value proposition to AWS users: forget about virtual machines and just provision containers. Amazon will take care of the underlying hosts, so you will be able to focus on writing software instead of maintaining and upgrading a fleet of Linux instances. Fargate brings many benefits to the table, including small maintenance overhead, lower attack surface, and granular pricing. However, as any cloud asset, leaving your AWS Fargate tasks unattended can lead to nasty surprises.

Securing AWS Fargate serverless workloads can be tricky as AWS does not provide much detail about the internal workings. After all… it’s not your business, AWS manages the scaling of underlying resources for you. :) While the security and stability of Fargate’s system is an inherent feature, Fargate follows a shared responsibility model, where you still have to take care of securing those parts specific to your application..

The CVE-2021-25735 medium-level vulnerability has been found in Kubernetes kube-apiserver that could bypass a Validating Admission Webhook and allow unauthorised node updates. The kube-apiserver affected are: You are only affected by this vulnerability if both of the following conditions are valid: By exploiting the vulnerability, adversaries could bypass the Validating Admission Webhook checks and allow update actions on Kubernetes nodes.

Today, I am excited to share that we secured $188M in a new funding round, at a valuation of $1.19B (read more here). At the outset, I want to thank our employees, partners, investors and most importantly, our customers for this important milestone. The funding follows a year of unmatched innovation that led to accelerated revenue growth, installed base growth, and rapid community adoption of our open source projects.

Recently, Amazon AWS introduced the new feature EC2 Serial Console for instances using Nitro System. It provides a simple and secure way to perform troubleshooting by establishing a connection to the serial port of an instance. Even though this feature is useful in case of break glass situations, from a security perspective, it could be used by adversaries to gain access through an unguarded secondary entrance.

The CVE-2021-20291 medium-level vulnerability has been found in containers/storage Go library, leading to Denial of Service (DoS) when vulnerable container engines pull an injected image from a registry. The container engines affected are: Any containerized infrastructure that relies on these vulnerable container engines are affected as well, including Kubernetes and OpenShift.

Detecting malicious processes is already complicated in cloud-native environments, as without the proper tools they are black boxes. It becomes even more complicated if those malicious processes are hidden. A malware using open source tools to evade detection has been reported. The open source project used by the malware is libprocesshider, a tool created by Sysdig’s former chief architect Gianluca.
