  • Browser makers cite coronavirus, restore support for obsolete TLS 1.0 and 1.1 encryption

    By common agreement, Google's Chrome, Microsoft's Internet Explorer (IE) and Edge, and Mozilla's Firefox were to disable support for TLS 1.0 and 1.1 early in 2020. They, along with Apple - which produces Safari - announced the move a year and a half ago, noting then that the protocols had been made obsolete by TLS 1.2 and 1.3.

    Apple, Google and Mozilla had committed to dropping support in March 2020, while Microsoft had only promised to purge TLS 1.0 and 1.1 sometime during the first half of this year.

    But it was Microsoft that was most detailed about the TLS turnabout. "In light of current global circumstances, we will be postponing this planned change - originally scheduled for the first half of 2020," Karl Pflug, of the Edge developer experience team, wrote in a post to a company blog.

  • Google Squashes High-Severity Flaws in Chrome Browser

    Do you use Google Chrome as your web browser? Google has patched high-security vulnerabilities in its Chrome browser, and is rolling out the newest Chrome browser version in the coming days.

    [...]

    As is typical for Chrome updates, Google is initially scant in details of the bugs “until a majority of users are updated with a fix.” It did outline three of the vulnerabilities that were discovered by external researchers, however.

    These included two high-severity vulnerabilities the WebAudio component of Chrome (CVE-2020-6450 and CVE-2020-6451). The WebAudio component is used for processing and synthesizing audio in web applications.

    The flaws tied to CVE-2020-6450 and CVE-2020-6451 are both use-after-free flaws. Use after free is a memory corruption flaw where an attempt is made to access memory after it has been freed. This can cause an array of malicious impacts, from causing a program to crash, to potentially leading to execution of arbitrary code.

  • How YubiKey Bio could make remote security concerns a thing of the past

    The bottom line is, your office brings a level of built-in security that’s not as readily available at home. Even if your Wi-Fi is WPA2-encrypted with a strong password, the security on your PC and personal accounts likely pales in comparison to the firewalls and intranets inside your office. “This is the perfect scenario for an attacker to thrive in and opens opportunities for social engineering and phishing attacks––making it imperative for businesses to develop a contingency plan that includes securing remote workers,” said Appenzeller. “Enabling multi-factor authentication wherever possible is one of the best ways to protect a remote team and should be a top requirement for a work-from-home policy.”

  • 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.
