  • Looking Back at the Top Cyber-Security Incidents of 2018

    As 2018 draws to a close, it's a good time to reflect on the year that was in cyber-security, to learn from past mistakes and identify trends that will likely continue into the new year.

    2018 saw no shortage of major breaches, new critical vulnerabilities and policy changes that enterprise IT organizations will still be grappling with in one form or another in 2019. 2018 was the year of Meltdown and Spectre and it was the year that GDPR came into effect. 2018 was also a year of intense security privacy challenges for Facebook and it was also a year in which tens of millions of Americans had their data stolen in large data breaches.

    In this year-end wrap-up, eWEEK looks back at some of the top IT security incidents of 2018.

  • GNOME Security Internship - Update 2

    This is something still in its early stage. In a first version, if the screen is not locked and you plug a keyboard the screen will be locked.

    This works good in theory but not in practice, because not only devices with physical keys are keyboards. For example the devices for hardware 2FA (e.g. yubikey) are also keyboards, and locking the screen every time you plug one of those is not a pleasant experience. So for a first implementation this solution is ok, but it definitely needs to be improved.

    One way to do it can be by mapping scancodes to keycodes, limiting particular devices capabilities (e.g. prevent them to use risky keys like “alt” or “ctrl”). Anyway this will require more research about what we can do and what’s the best way to do it.

  • Fuzzing Like It’s 1989

    With 2019 a day away, let’s reflect on the past to see how we can improve. Yes, let’s take a long look back 30 years and reflect on the original fuzzing paper, An Empirical Study of the Reliability of UNIX Utilities, and its 1995 follow-up, Fuzz Revisited, by Barton P. Miller.

    In this blog post, we are going to find bugs in modern versions of Ubuntu Linux using the exact same tools as described in the original fuzzing papers. You should read the original papers not only for context, but for their insight. They proved to be very prescient about the vulnerabilities and exploits that would plague code over the decade following their publication. Astute readers may notice the publication date for the original paper is 1990. Even more perceptive readers will observe the copyright date of the source code comments: 1989.

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • 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.
