  • Researchers Detail Privilege Escalation Bugs Reported in Oracle VirtualBox

    A now-patched vulnerability affecting Oracle VM VirtualBox could be potentially exploited by an adversary to compromise the hypervisor and cause a denial-of-service (DoS) condition.

    "Easily exploitable vulnerability allows high privileged attacker with logon to the infrastructure where Oracle VM VirtualBox executes to compromise Oracle VM VirtualBox," the advisory reads. "Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DoS) of Oracle VM VirtualBox"

  • How the SAML Standard Provides Single Sign-On Services – CloudSavvy IT

    Single Sign-On and zero trust networks depend on securely passing identification details back and forth between users, identity providers, and service providers. SAML is the glue that lets that happen.

  • What is the OSI Model - 7 Layers of OSI Model Explained

    International Organization for Standardization (ISO) developed the OSI model in 1984.

    OSI model is an acronym for Open System Interconnect.

    The OSI model is a model that allows us to categorize network communications and divide different activities of the network in seven conceptual layers.
    This model tries to explain how the data of an application passes through the device and out in the physical network using the seven conceptual steps or layers.

    In simpler words, it explains how one application performs different steps to communicate its data to another application running on a different device.

    The OSI model was created for creating a common industry standard, which could have helped inter-operability between different vendors.

    However, this model did not gain a lot of popularity. So it is used as a reference or a teaching tool today. The OSI model does not directly match the networking systems we use in reality, but it is still useful because it describes the several processes used in electronic communication.

  • New Linux malware hides in cron jobs with invalid dates [Ed: This is not a "Linux" issue; it's about applications that run over the Web and have holes in them, maybe because admins do not patch them]

    Security researchers have discovered a new remote access trojan (RAT) for Linux that keeps an almost invisible profile by hiding in tasks scheduled for execution on a non-existent day, February 31st.

    Dubbed CronRAT, the malware is currently targeting web stores and enables attackers to steal credit card data by deploying online payment skimmers on Linux servers.

  • 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.
