  • Useful web hosting tips that can help secure your site

    Website security is about preparing for the worst if applied security mechanisms fail. After all, protecting your site from every threat on the book can be laborious. However, it does not mean website owners should not try. It simply refers to the two sides of the coin: preventing attacks or other interruptions and mitigating successful ones.

    Thus, it might be an excellent idea to review the security of your business website to ensure you don’t end up a victim of vicious attacks. Considering that, here are the top 7 definitive web hosting tips to help secure your site for the foreseeable future.

  • Free Training Course Teaches How to Secure a Software Supply Chain with Sigstore [Ed: OpenSSF (former Microsoft) telling you to deny people who want to run applications of their choice; they call that "security"]
  • Learn the Principles of DevSecOps in New, Free Training Course [Ed: This is what Zemlin et al are 'teaching']

    At the most basic level, there is nothing separating DevSecOps from the DevOps model. However, security, and a culture designed to put security at the forefront has often been an afterthought for many organizations. But in a modern world, as costs and concerns mount from increased security attacks, it must become more prominent. It is possible to provide continuous delivery, in a secure fashion. In fact, CD enhances the security profile. Getting there takes a dedication to people, culture, process, and lastly technology, breaking down silos and unifying multi-disciplinary skill sets. Organizations can optimize and align their value streams towards continuous improvement across the entire organization.

  • Keeping PowerShell: Measures to Use and Embrace [Ed: Has CISA become a "damage control" or PR department of Microsoft?]

    Cybersecurity authorities from the United States, New Zealand, and the United Kingdom have released a joint Cybersecurity Information Sheet (CIS) on PowerShell. The CIS provides recommendations for proper configuration and monitoring of PowerShell, as opposed to removing or disabling it entirely due to its use by malicious actors after gaining access into victim networks. These recommendations will help defenders detect and prevent abuse by malicious cyber actors, while enabling legitimate use by administrators and defenders.

  • For a few days earlier this year, rogue GitHub apps could have hijacked countless repos

    A GitHub bug could have been exploited earlier this year by connected third-party apps to hijack victims' source-code repositories.

    For almost a week in late February and early March, rogue applications could have generated scoped installation tokens with elevated permissions, allowing them to gain otherwise unauthorized write or administrative access to developers' repos. For example, if an app was granted read-only access to an organization or individual's code repo, the app could effortlessly escalate that to read-write access.

    This security blunder has since been addressed and before any miscreants abused the flaw to, for instance, alter code and steal secrets and credentials, according to Microsoft's GitHub, which assured The Register it's "committed to investigating reported security issues."

    This is good news, because according to Aqua Security researchers, exploitation would have had a massive impact on "basically everyone." In effect, this is a near hit for the industry as miscreants could have exploited the hole to exfiltrate cloud credentials from private repos or potentially tamper with software projects.

  • 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.
