4 Best Linux Open source Firewall for Cyber Security - 2022

Submitted by Rianne Schestowitz on Monday 7th of March 2022 04:47:14 PM Filed under
Security

We need a well-configured Firewall, which is a key component of network security when we are about to expose our internal network to the outside world. Although our operating systems come with some kind of firewall software, however, they are not enough to protect each device of a network. Hence, we need a dedicated Firewall. The advantage of open-source firewalls is that it is completely free and there are no verifiable backdoors because the open-source firewall code is known and has a good reputation. It usually takes a little longer to install and configure this, but this technology is worth a closer look and is worthwhile.

One of the other benefits of using open source firewalls is they are not restricted to some particular hardware type. The user can install them on the existing hardware and connect them to the Internet. In this way, they work quickly and do not compromise the security of the network. On the contrary, especially for administrators who have less experience, open-source firewalls bring great advantages, because they are quicker and easier to set up. Of course, one cannot expect a free, open-source firewall variant to have the same functions and support services as a paid commercial firewall. However, this is not absolutely necessary as long as you have a stable internet connection.

  • 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.
