Providing Visibility and Security for AWS App Mesh

Microservice architectures running on containers have made applications easier to scale and faster to develop. As a result, enterprises are able to innovate faster and accelerate time-to-market for new features. To make management of microservices even more efficient and easier to run, service mesh solutions like Istio, Envoy, and Linkerd – and now AWS App Mesh – have become the next core building blocks of microservices infrastructure built on containers.

Monitoring StatsD: metric types, format & code examples

The StatsD stack is one of the most popular monitoring solutions to instrument your code using custom metrics. In this post we will describe the StatsD metrics architecture, metrics types and formats, proving code examples for the Golang, NodeJS/Javascript and Python programming languages.

Detecting and preventing cgroups escape via SCTP - CVE-2019-3874

This week CVE-2019-3874 was discovered which details a flaw in the Linux kernel where an attacker can circumvent cgroup memory isolation using the SCTP socket buffer. In containerised environments, this has the potential for a container running as root to create a DoS.

Prometheus metrics / OpenMetrics code instrumentation

In the following example-driven tutorial we will learn how to use Prometheus metrics / OpenMetrics to instrument your code whether you are using Golang, Java, Python or Javascript. We will cover the different metric types and provide readily executable code snippets. Prometheus is an open source time series database for monitoring that was originally developed at SoundCloud before being released as an open source project.

Detecting the Kubernetes API Server DoS Vulnerability (CVE-2019-1002100)

Recently, a new Kubernetes related vulnerability was announced that affected the kube-apiserver. This was a denial of service vulnerability where authorized users with write permissions could overload the API server as it is handling requests. The issue is categorized as a medium severity (CVSS score of 6.5) and can be resolved by upgrading the kube-apiserver to v1.11.8, v1.12.6, or v1.13.4.

Better together with Sysdig and Anchore: Comprehensive container security across the software development lifecycle

In the new cloud-native world, ephemeral services like containers make security a challenging task. As enterprises start adopting containers in production, they suffer from a great deal of variance in the software, configuration, and other static artifacts that exist across their organization’s container image set.

ContainerD meets Sysdig

Containers are fast becoming the defacto standard as a building block for creating and deploying applications. Containerization allows development teams to have consistent environments, cost optimizations, isolation, and versatility, in general. The open-source Containerd project is a critical component for the modern cloud-native containerized landscape, providing a runtime that is widely used in millions of applications every day.
