  • Fedora Dev Teaches Users How to Protect Their Wi-Fi Against WPA2 KRACK Bug

    Former Fedora Project leader Paul W. Frields talks today about how to protect your Fedora computers from the dangerous WPA2 KRACK security vulnerability that affects virtually any device using the security protocol to connect to the Internet.

  • WPA2 was kracked because it was based on a closed standard that you needed to pay to read

    How did a bug like krack fester in WPA2, the 13-year-old wifi standard whose flaws have rendered hundreds of millions of devices insecure, some of them permanently so?

    Thank the IEEE's business model. The IEEE is the standards body that developed WPA2, and they fund their operations by charging hundreds of dollars to review the WPA2 standard, and hundreds more for each of the standards it builds upon, so that would-be auditors of the protocol have to shell out thousands just to start looking.

    It's an issue that Carl Mamamud, Public Resource and the Electronic Frontier Foundation have been fighting hard on for years, ensuring that the standards that undergird public safety and vital infrastructure are available for anyone to review, audit and criticize.

  • Patch Available for Linux Kernel Privilege Escalation

    The issue — tracked as CVE-2017-15265 — is a use-after-free memory corruption issue that affects ALSA (Advanced Linux Sound Architecture), a software framework included in the Linux kernel that provides an API for sound card drivers.

  • ​Linus Torvalds says targeted fuzzing is improving Linux security

    Announcing the fifth release candidate for the Linux kernel version 4.14, Linus Torvalds has revealed that fuzzing is producing a steady stream of security fixes.

    Fuzzing involves stress testing a system by generating random code to induce errors, which in turn may help identify potential security flaws. Fuzzing is helping software developers catch bugs before shipping software to users.

  • Q&A: Does blockchain alleviate security concerns or create new challenges?

    According to some, blockchain is one of the hottest and most intriguing technologies currently in the market. Similar to the rising of the internet, blockchain could potentially disrupt multiple industries, including financial services. This Thursday, October 19 at Sibos in Toronto, Hyperledger’s Security Maven Dave Huseby will be moderating a panel “Does Blockchain technology alleviate security concerns or create new challenges?” During this session, experts will explore whether the shared nature of blockchain helps or hinders security.

  • 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.
