  • A glossary of terms about cyberattacks, from ransomware to DDoS

    If you read news about technology, you’re bound to run into some jargon. Here at Mozilla, we believe that information should be as accessible as possible regardless of your level of expertise. We want to help you approach stories about technology with more curiosity and with a little less head-scratching involved. We’ll break down headline-making topics through a glossary of terms often used to discuss them. Consider it your cheat sheet to all things tech.

  • What is a cyberattack and what can we do to protect ourselves online?

    Cyberattacks are nothing new. According to the FBI, the first major “attack on the internet” predated even the web — a self-replicating malicious program created by a grad student who shortly apologized with instructions to remove it. While the software didn’t damage or destroy any files, it spread, within 24 hours, to about 6,000 of the 60,000 computers that were connected to the internet at the time. It slowed down university and military operations and delayed email for days. The apology that contained the fix reached few people in time.

    To say that our lives have become more dependent on the internet since the Morris worm of 1988 would be an understatement. A cyberattack can disrupt fuel supplies by shutting down the largest pipeline in the U.S. It can cut electricity for entire regions. It can disable computers at hospitals. No wonder cyberattacks have become destructive tools during international conflicts like the Russia-Ukraine war.

    With cyberattacks making headlines, we turned to Mozilla’s chief security officer to shed some light on the role of cybersecurity during the Russia-Ukraine war. Marshall Erwin has worked in cybersecurity for two decades, spending the first five years of his career in the CIA’s counterterrorism center. He also spent some time working on cybersecurity policy issues in the U.S. Congress before taking the lead on trust and security at Mozilla seven years ago.

  • Mozilla Releases Security Updates for Firefox, Firefox ESR, and Thunderbird

  • Chromium 100 out-of-band security update addresses (again) a single vulnerability | Alien Pastures

    What’s with all these updates that follow rapidly on each others’ heels? Just like the recent Chromium 99 security update which addressed a single critical vulnerability, last monday Google announced on their official blog the immediate availability of Chromium 100.0.4896.75. This hotfix release plugs a single hole which Google deemed serious enough to warrant the update. See CVE-2022-1232. The difference with last week is that no known exploit of this vulnerability is reported yet.

  • 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.
