Security

Red Hat Enterprise Linux 9 (RHEL 9) is the latest version of Red Hat’s flagship operating system, released at the Red Hat Summit in May 2022. New capabilities added to RHEL 9 help simplify how organizations manage security and compliance when deploying new systems or managing existing infrastructure. This article takes a brief look at three of the new security features available in this release.

The default superuser account in Unix- and Linux-based systems is "root". Because the username is always "root" and access rights are unlimited, this account is the most valuable target for hackers. Attackers use bots to scan for systems with exposed SSH ports, and when found, they attempt to use common usernames and brute-force passwords to gain entry. Of course, the impact of a successful exploit would be a lot lower if the compromised user has unprivileged access. The breach would then be contained and limited to one user only.

  • 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.
