Many organizations have security policies in place that dictate how to store sensitive information. When you're developing applications for the cloud, you're probably expected to follow those policies, and to do that you often have to externalize your data storage. Kubernetes has a built-in system to access external secrets, and learning to use that is key to a safe cloud-native app.

Fail2ban is free and open-source IPS (Intrusion Prevention Software) that helps administrators secure Linux servers against malicious login and brute-force attacks.

Version 251 of the controversial systemd Linux init system is here, and you can expect it to feature in the next version of your preferred distro. The unified system and service manager for Linux continues to grow and develop, as does Linux itself.

In this first part of our Complete Guide to Keylogging in Linux, we will explore the basics of keylogging and its importance in the realm of Linux security, and dive deeper into keylogging in userspace, demonstrating how a keylogger can be written for Linux, by reading events directly from a keyboard device.

Sfera Labs released the Exo Sense RP which is a compact module that combines sensors to monitor air quality, humidity, temperature, light, motion and audio sensing.

What advice would you give a new Linux user? We asked our community of writers to share their favorite Linux advice.

Understand the key concepts behind images and containers. Then try a lab that demonstrates building and running images and containers.

When Java was developed in 1995, its goal was to be a single language for unified software delivery. Write your code once, and run it on any computer. It was a lofty goal then, and for many languages, it's a goal that remains elusive even today. Java has managed, in its 27-year lifespan, to achieve its stated goal. It drives applications on desktops, servers, and the cloud, and it's the foundation of the Android operating system.

One-stop DevOps shop GitLab has announced version 15 of its platform, hot on the heels of pull-based GitOps turning up on the platform's free tier. Version 15.0 marks the arrival of GitLab's next major iteration and attention this time around has turned to visibility and observability – hardly surprising considering the acquisition of OpsTrace as 2021 drew to a close, as well as workflow automation, security and compliance.

Amazon WorkSpaces is a Desktop-as-a-Service (DaaS) solution managed by AWS. We can use it to provision either Windows or Linux desktops. These desktops can be created in just a few minutes. They can quickly scale to provide thousands of desktops.

Broadcom is in early talks to buy VMware, according to The New York Times, Bloomberg, and Reuters. VMware is not commenting on the matter. This one is interesting, because the three sources we've linked to above all say they've got the news from "a person familiar with the matter." All say the deal is nowhere near done, a price has not been discussed, and a transaction is far from certain to happen.

Hearing "open-source", "PSP", and "security" all together got me excited with my initial reaction thinking it was about AMD's Platform Security Processor (PSP) albeit that's not the case here. Google's PSP announced today is the "PSP Security Protocol" and is designed for dealing with cryptographic hardware offloading at data center scale and used by Google already in production.

Linus Torvalds has released version 5.18 of the Linux kernel. The maintainer-in-chief’s post announcing the release was typical of those he made for each of the eight release candidates: this time around he found no nasty surprises, additions were neither major nor complex, and no glitches impacted the development process.

Calendar apps are a necessity for keeping track of events and your to-do tasks in this hectic modern work life. These apps can help you never forget anything again.

If you're a musician of any kind, from beginner to professional, Linux provides an amazing assortment of free, yet powerful, platforms and applications that will boost your productivity and help you to show off your creativity.

The power of a story. I first wrote about this 7 years ago in a series I titled Lessons from a Two Year Old. But it is a reality as old as time itself – humans are wired for stories. We enjoy listening to them, telling them, and they help us to relate to others and to remember things. And everyone has a story to tell – many of which haven’t been told yet.

Last week I had the privilege of participating in the Open Source Software Security Summit II in Washington, DC. The Linux Foundation and OpenSSF gathered around 100 participants from enterprise, the U.S. government, and the open source community to agree on an action plan to help increase the security of open source software.

Mozilla on Wednesday launched a Developer Preview program to solicit feedback on Firefox extensions that implement Manifest v3, a Google-backed revision of browser extension architecture.

One of Git's primary strengths is its ability to "fork" work into different branches. If you're the only person using a repository, the benefits are modest, but once you start working with many other contributors, branching is essential. Git's branching mechanism allows multiple people to work on a project, and even on the same file, at the same time. Users can introduce different features, independent of one another, and then merge the changes back to a main branch later. A branch created specifically for one purpose, such as adding a new feature or fixing a known bug, is sometimes called a topic branch.

Kubernetes dashboard provides a web-based UI for the cluster. One can deploy applications on the cluster using the dashboard as well as troubleshoot the existing applications in the cluster.
