  • 6 Kubernetes security questions, answered

    If you’re asking questions about Kubernetes to learn more about the platform, security will be on your list. The good news: both the open source project and the commercial platforms that sit on top of it have plenty of strong security-related features baked in. Moreover, there’s a lively Kubernetes community with a shared interest in the ongoing security of the orchestration tool.

    “The Kubernetes community has had security at the forefront of their minds from the start,” says Wei Lein Dang, VP of products at StackRox.

    As with many technologies, though, the security risks tend to follow the adoption curve. So as the use of containers expands, expect Kubernetes to become an important focal point for security in containerized environments.

  • The security of dependencies

    So you’ve written some software. It’s full of open source dependencies. These days all software is full of open source, there’s no way around it at this point. I explain the background in my previous post.

    Now that we have all this open source, how do we keep up with it? If you’re using a lot of open source in your code there could be one or more updated dependencies per day!

    Step one is knowing what you have. There are a ton of ways to do this, but I’m going to bucket things into 3 areas.

  • Buffer Overflow Vulnerability in TP-Link Routers Can Allow Remote Attackers to Take Control

    Internet routers are among the most ubiquitous devices home and business users depend on every day to carry out communications, banking, shopping and commercial transactions. IBM Security researcher Grzegorz Wypych (aka h0rac) took a closer look at one of the most widespread internet routers in use by consumers nowadays, the TP-Link WR-940, and found that a zero-day buffer overflow vulnerability in the router could allow malicious third parties to take control of the device from a remote location.

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
