  • Fedora 35 Looking To Use Yescrypt For Hashing User Passwords - Phoronix

    Adding to the list of planned improvements for Fedora 35 is switching to make use of Yescrypt for hashing of user passwords.

    Fedora developers are looking at using Yescrypt as the default hashing mode for new user passwords within /etc/shadow. While SHA256/SHA512 haven't yet been broken as common used today for Linux account password hashing, Yescrypt would beef up the security.

  • Vulnerability Detection and Patching: A Survey Of The Enterprise Environment | Linux Journal

    Detecting vulnerabilities and managing the associated patching is challenging even in a small-scale Linux environment. Scale things up and the challenge becomes almost unsurmountable. There are approaches that help, but these approaches are unevenly applied.

    In our survey, State of Enterprise Vulnerability Detection and Patch Management, we set out to investigate how large organizations handle the dual, linked security concerns of vulnerability detection and patch management.

    The results produced interesting insights into the tools that organizations depend on to effectively deal with vulnerability and patch management at scale, how these tools are used, and which restrictions organizations face in their battle against threat actors.

  • Mozilla Attack & Defense: Eliminating Data Races in Firefox – A Technical Report

    We successfully deployed ThreadSanitizer in the Firefox project to eliminate data races in our remaining C/C++ components. In the process, we found several impactful bugs and can safely say that data races are often underestimated in terms of their impact on program correctness. We recommend that all multithreaded C/C++ projects adopt the ThreadSanitizer tool to enhance code quality.

  • 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.
