  • Security Expert Tadayoshi Khono Joins EFF Advisory Board

    EFF is proud to announce a new addition to our crack advisory board: security expert and scholar Tadayoshi Khono. A professor at University of Washington’s Paul G. Allen School of Computer Science & Engineering, Khono is a researcher whose work focuses on identifying and fixing security flaws in emerging technologies, the Internet, and the cloud.Khono examines and tests software and networks with the goal of developing solutions to security and privacy risks before those risks become a threat. His research focuses on helping protect the security, privacy, and safety of users of current and future generation technologies.Khono has revealed security flaws in electronic voting machines, implantable cardiac defibrillators, and pacemakers, and automobiles. He recently studied flaws in augmented reality (AR) apps, and last year co-developed a tool for developers to build secure multi-user AR platforms. A 2019 report he co-authored about the genealogy site GEDmatch, used to find the Golden State Killer, showed vulnerabilities to multiple security risks that could allow bad actors to create fake genetic profiles and falsely appear as a relative to people in the GEDmatch database.Khono has spent the last 20 years working to raise awareness about computer security among students, industry leaders, and policy makers. He is the recipient of an Alfred P. Sloan Research Fellowship, a U.S. National Science Foundation CAREER Award, and a Technology Review TR-35 Young Innovator Award. He has presented his research to the U.S. House of Representatives, and had his research profiled in the NOVA ScienceNOW “Can Science Stop Crime?” documentary and the NOVA “CyberWar Threat” documentary. Kohno received his Ph.D. from the University of California at San Diego, where he earned the department’s Doctoral Dissertation Award.We’re thrilled that Khono has joined EFF’s advisory board.

  • Why you should be using Multi-Category Security for your Linux containers

    In our last post, we discussed SELinux and how it can be used to improve container security. We also looked at the Multi-Level Security (MLS) and Multi-Category Security (MCS) models. In this post, we'll compare those models and explain why we believe MCS to be a better approach to container security.

    We often describe SELinux policy for containers as "what happens in Vegas stays in Vegas." What we mean by this is we use SELinux to keep the processes inside of the container file system. If somehow they break out of container confinement, SELinux can prevent them from reading and writing other content on the hosts file systems.

    SELinux has been proven to block container breakouts based on file system attacks. The goal of MLS is similar in that it allows the processes running in the same sensitivity level to read/write all of the content at the same level.

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • 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.
