Networks today are moving towards increased agility and dynamic capabilities to support advanced networking requirements and business-critical processes. This causes the IT infrastructure to span across wireless, virtual, and hybrid environments as well. But with networks evolving quickly, IT admins have a hard time managing them without the right solutions in place.
If you’re a developer who lives and breathes code all day, you probably don’t mind having to write complex configuration files to set up an automation tool or configure a management policy. But the fact is that many of the stakeholders who stand to benefit from security automation are not developers.
Throughout my career within the compliance and security space, I’ve seen the practice of proactively managing digital risk move from a nice-to-have to a must-have for enterprise organizations. And over the last 5 years, things have shifted drastically. Personally, it reminds me of the classic “Dry Bones” nursery rhyme song that my son loves so much which points out how all the different bones are connected to make one body.
A typical IoT application with any physical system or process in the field can have hundreds of on-site sensors generating copious amounts of data every second and possibly communicating in several different protocols.
Current IT monitoring software lacks the necessary metrics for minimizing downtime for systems and applications. Most provide system and application metrics but there is much more than this required for properly monitoring your infrastructure. With eBPF there is a technological advancement that allows monitoring software to provide rich information from the Linux kernel and present it.
Using modules, you can add custom promise types to CFEngine, to manage new resources. In this blog post, I’d like to introduce some of the first official modules, namely git and systemd promise types. They were both written by Fabio Tranchitella, who normally works on our other product, Mender.io. He decided to learn some CFEngine and within a couple of weeks he’s contributed 3 modules, showing just how easy it is to implement new promise types. Thanks, Fabio!
If you are using HAProxy 2.0 or newer, it is important that you update to the latest version. A vulnerability was found that makes it possible to abuse the HTTP/2 parser, allowing an attacker to prepend hostnames to a request, append top-level domains to an existing domain, and inject invalid characters through the :method pseudo-header.
In the Kubernetes ecosystem there are a variety of ways for you to provision your cluster, and which one you choose generally depends on how well it integrates with your existing knowledge or your organization’s established tools. Kubespray is a tool built using Ansible playbooks, inventories, and variable files—and also includes supplemental tooling such as Terraform examples for provisioning infrastructure.
