Kubernetes resource limits are always a tricky setting to tweak, since you have to find the sweet spot between having the limits too tight or too loose. In this article, which is a continuation of the Kubernetes capacity planning series, you’ll learn how to set the right Kubernetes resource limits: from detecting the containers without any limit, to finding the right Kubernetes resource limits you should set in your cluster.

Calico is the industry standard for Kubernetes networking and security. It offers a proven platform for your workloads across a huge range of environments, including cloud, hybrid, and on-premises. Given this incredibly wide support, why did we decide to create a course specifically about AWS?

Let’s be honest for a second. This is a corporate blog. Yes, we aim to provide our readers with actionable, educational information. And, yes, we strive for complete transparency.

The Splunk Threat Research team recently developed a new analytic story to help security operations center (SOC) analysts detect adversaries executing password spraying attacks against Active Directory environments. In this blog, we’ll walk you through this analytic story, demonstrate how we can simulate these attacks using PurpleSharp, collect and analyze the Windows event logs, and highlight a few detections from the May 2021 releases.

The U.S. government is instituting stricter requirements on federal agencies and federal contractors to address cybersecurity threats. Adopting the right set of tools and practices will help organizations secure their software development supply chains and be prepared to meet these standards. However, the initial requirements also provide a valuable framework for any organization trying to reduce its security risk—not just government institutions and those doing business with them.

We recently released the automated Falco rule tuning feature in Sysdig Secure. Out-of-the-box security rules are a double-edged sword. On one side, they allow you to get started right away. On the other, it can take many working hours to learn the technology, configuration, and syntax to be able to customize the rules to fit your applications. Falco’s default security rules are no different.

In a recent post by ZDI, researchers found an out-of-bounds access flaw (CVE-2021-31440) in the Linux kernel’s (5.11.15) implementation of the eBPF code verifier: an incorrect register bounds calculation occurs while checking unsigned 32-bit instructions in an eBPF program. The flaw can be leveraged to escalate privileges and execute arbitrary code in the context of the kernel.
