  • Shedding light on the threat posed by shadow admins

    Few organizations would purposefully hand a huge responsibility to a junior staff member before letting them fly solo on their own personal projects, but that’s effectively what happens inside too many corporate networks: organizations delegate specific administrative access to user accounts so they can do a particular privileged task, and they promptly forget about it. These “shadow admin” accounts often get ignored by everyone except attackers and threat actors, for whom they are valuable targets.

    [...]

    Leaving shadow admin accounts on an organization’s AD is a considerable risk that’s best compared to handing over the keys to one’s kingdom to do a particular task and then forgetting to track who has the keys and when to ask for it back. It pays to know who exactly has privileged access, which is where AD admin groups help.

    Conversely, the presence of shadow admin accounts could be a sign that an attack is underway. If a threat actor can grant themselves permissions to create these accounts and then assign them with higher privileges, they can extend their attack in many directions.

  • 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.
