  • Free XSS Tools – Linux Hint

    Cross-Site Scripting, commonly known as XSS, is a type of vulnerability in which attackers remotely inject custom scripts on web pages. It commonly occurs in sites where data input parameters are improperly sanitized.

    Sanitization of inputs is the process of cleansing of the inputs, so the data inserted is not used to find or exploit security holes in a website or server.

    Vulnerable sites are either unsanitized or very poorly and incompletely sanitized. It is an indirect attack. The payload is indirectly sent to the victim. The malicious code is inserted on the website by the attacker, and then it becomes a part of it. Whenever the user (victim) visits the webpage, the malicious code is moved to the browser. Hence, the user is unaware of anything happening.

  • Josh Bressers: Episode 218 – The past was a terrible place

    Josh and Kurt talk about change. Specifically we discuss how the past was a terrible place. Never believe anyone who tells you it was better. Part of a career now is learning how to learn. The things you learn today won’t be useful skills in a few years. The future is is always better than the past. Even in 2020.

  • 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.
