Welcome to the second edition of Open Source Matters: our regular publication about the latest happenings in open source! Let’s dive into the news.

Kubernetes workloads are highly dynamic, ephemeral, and are deployed on a distributed and agile infrastructure. Application developers, DevOps teams, and site reliability engineers (SREs) often require better visibility of their different microservices, what their dependencies are, how they are interconnected, and which other clients and applications access them. This makes Kubernetes observability challenges unique.

Threat hunting is emerging as a must-have addition to cybersecurity strategies. By enabling organizations to find and mitigate threats before they ever touch their networks or systems, threat hunting provides the basis for a more proactive security posture – and one that delivers higher ROI on security tools and processes. How can businesses actually add threat hunting to their security arsenals? That’s where solutions like Sumo Logic's Cloud SIEM come in.

In the past 2 and half months, we have refreshed the visual design of the CFEngine Mission Portal. You might already notice some differences in the navigation, iconography, and color set. This is a post to guide you through the major changes we made and also provide you an inside perspective into the design direction we are taking going forward.

A modified version of this blog post appeared in the June 2021 issue of Signal magazine. Decisions that need to be made in an instant require answers in real time, but existing big data systems are unable to return queries quickly enough for real-time analytics. And with growing data being queried by more connected users than ever before, it’s getting increasingly challenging to maintain fast reaction times.

The ongoing news of massive cyberattacks on manufacturing and energy companies has been a wake-up call. Operational Technology (OT) Security had not been on the radar of many CISOs and plant managers until they got hit. After reacting in a defensive mode last year it is time to step up with a proactive security strategy including OT. Secure Factory by Splunk helps manufacturing companies better understand and address their unique security challenges.

As my colleague, Tim Frank, wrote about recently in his blog post, "The Department of Defense Data Strategy: An Important Start," in late 2020 the Department of Defense (DoD) released its new Data Strategy — providing focus and direction for the Department’s efforts to become data-centric at all levels of its enterprise.

Companies generate data at an exponential rate, and the task of analyzing data to produce relevant security insights can be overwhelming. With evolving market dynamics and threat landscapes, security teams have a greater need for integrated and scalable monitoring that provides real-time and meaningful insights into the state of organizational security posture.

When it comes to security threats, a few minutes additional response time can make the difference between a minor nuisance and a major problem. Datadog Security Monitoring enables you to easily triage and alert on threats as they occur. In this post, we’ll look at how you can use Datadog’s webhooks integration to automate responses to common threats Datadog might detect across your environments.
