  • Sorting out old password hashes

    Starting with libxcrypt 4.4.21, weak password hashes (such as MD5 and SHA1) are no longer accepted for new passwords. Users that still have their passwords stored with a weak hash will be asked to update their password on their next login.

  • ransomware costs are projected to reach $20 billion in 2020 – spending in the cybersecurity industry reached $40.8 billion in 2019 but has actually gone done in 2021

    “In 2019, spending in the cybersecurity industry reached around $40.8 billion, with forecasts suggesting that the market will eclipse 54 billion U.S. dollars by 2021 as the best-case scenario, taking into account the coronavirus (COVID-19) impact. As many organizations around the world rely on cloud services to empower a remotely working workforce, spending on cybersecurity is an important priority in order to ensure the protection of sensitive data, for example.”

  • the vulnerability remediation lifecycle of Alpine containers – Ariadne's Space

    Anybody who has the responsibility of maintaining a cluster of systems knows about the vulnerability remediation lifecycle: vulnerabilities are discovered, disclosed to vendors, mitigated by vendors and then consumers deploy the mitigations as they update their systems.

    In the proprietary software world, the deployment phase is colloquially known as Patch Tuesday, because many vendors release patches on the second and fourth Tuesday of each month. But how does all of this actually happen, and how do you know what patches you actually need?

    I thought it might be nice to look at all the moving pieces that exist in Alpine’s remediation lifecycle, beginning from discovery of the vulnerability, to disclosure to Alpine, to user remediation. For this example, we will track CVE-2016-20011, which I just fixed in Alpine, which is a minor vulnerability in the libgrss library concerning a lack of TLS certificate validation when fetching https URIs.

  • 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.
