  • A New Method of Containment: IBM Nabla Containers

    In the previous post about Containers and Cloud Security, I noted that most of the tenants of a Cloud Service Provider (CSP) could safely not worry about the Horizontal Attack Profile (HAP) and leave the CSP to manage the risk.  However, there is a small category of jobs (mostly in the financial and allied industries) where the damage done by a Horizontal Breach of the container cannot be adequately compensated by contractual remedies.  For these cases, a team at IBM research has been looking at ways of reducing the HAP with a view to making containers more secure than hypervisors.  For the impatient, the full open source release of the Nabla Containers technology is here and here, but for the more patient, let me explain what we did and why.  We’ll have a follow on post about the measurement methodology for the HAP and how we proved better containment than even hypervisor solutions.

    [...]

    Like most sandbox models, the Nabla containers approach is an alternative to namespacing for containment, but it still requires cgroups for resource management.  The figures show that the containment HAP is actually better than that achieved with a hypervisor and the performance, while being marginally less than a namespaced container, is greater than that obtained by running a container inside a hypervisor.  Thus we conclude that for tenants who have a real need for HAP reduction, this is a viable technology.

  • Rewritten GandCrab Ransomware Targets SMB Vulnerabilities To Attack Faster

    GandCrab ransomware, which has created a hullabaloo in the cybersecurity industry by constantly evolving, has yet again caused a commotion. The latest version of the ransomware attacks system using SMB exploit spreader via compromised websites. The ransomware is adding new features every day to target different countries.

    The attackers behind the ransomware are scanning the whole internet to find the vulnerable websites to unleash the attack. The latest version features a long hard-coded list of websites that were compromised and were used to connect with it.

  • France’s cyber command marched in Paris’s Bastille Day Parade for the first time

     

    For the first time, France’s military cyber command marched in this year’s Bastille Day parade on the Champs Elysees in Paris, alongside other units in the nation’s armed forces. The military noted that it’s a recognition of the advances that the unit has made since its formation last year, and reinforces that “cyber defense remains a national priority.”
     

    French defense minister Jean-Yves Le Drian announced the formation of COMCYBER in December 2016, noting that the emergence of state actors operating in cyberspace was a new way to approach warfare. The command brought all of the nation’s soldiers focused on cyber defense under one command, with three main tasks: cyber intelligence, protection, and offense.

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.
