  • Intel and Canonical to secure containers software supply chain

    Today, cloud-native developers benefit from an abundance of resources to compose their applications. With container images, packaging all these resources in a standard, easy-to-reuse format is now easier than ever. Unfortunately, container images also make it easier to package unneeded, vulnerable software or even malicious resources.

    Knowing which resources to use and what is a safe base layer when starting a cloud-native project is challenging. Extreme caution should go into picking these dependencies deliberately. Organisations need to provide their developers with “sane defaults”, trusted sources to underpin and support applications.

  • Linux patching — the why and the how |

    Since the region’s governments initiated their economic-diversification initiatives, Middle East enterprises have been digitising at a robust pace, putting them squarely in the crosshairs of cybercriminals. But when COVID-19 struck, and businesses and governments flocked to the cloud for its promise of continuity, things got worse. In the UAE, for example, the nation’s top cybersecurity official revealed a 250% increase in attacks from 2019 to 2020. This is what bad actors do. They take advantage of circumstances, any circumstances, to pounce.

    And what a circumstance the pandemic turned out to be for digital malefactors. To settle quickly into their new homes in the cloud, regional organisations had to accept new, untested ecosystems. Multiple network domains that fell outside the control of IT, coupled with a mushrooming of Shadow IT, dumped alien environments on the heads of thousands of under-resourced tech teams.

  • Rust-proofing the internet with ISRG's Prossimo

  • Microsoft Nov. Patch Tuesday Fixes Six Zero-Days, 55 Bugs [Ed: It's even worse than this because Microsoft admitted that it plugs some security holes without ever announcing the corresponding bugs at all]

    Experts urged users to prioritize patches for Microsoft Exchange and Excel, those favorite platforms so frequently targeted by cybercriminals and nation-state actors.

    Microsoft reported a total of 55 vulnerabilities, six of which are rated critical, with the remaining 49 being rated important. The flaws are found in Microsoft Windows and Windows Components, Azure, Azure RTOS, Azure Sphere, Microsoft Dynamics, Microsoft Edge (Chromium-based), Exchange Server, Microsoft Office and Office Components, Windows Hyper-V, Windows Defender, and Visual Studio.

  • Pun-free Cylance vulnerability, fixed | Pen Test Partners

    A heap overflow resulting in a denial of service, low privilege arbitrary file delete and an elevation of privilege from limited service accounts to SYSTEM.

    It is recommended that the software is either upgraded to the latest 158x stream or version 1578 at the time of writing. Further information on the advisory can be found here.

  • 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.
