  • Likely Drone Attack On U.S. Power Grid Revealed In New Intelligence Report (Updated)

    U.S. officials believe that a DJI Mavic 2, a small quadcopter-type drone, with a thick copper wire attached underneath it via nylon cords was likely at the center of an attempted attack on a power substation in Pennsylvania last year. An internal U.S. government report issued last month says this is the first time such an incident has been officially assessed as a possible drone attack on energy infrastructure in the United States, but that this is likely to become more commonplace as time goes on. This is a reality The War Zone has sounded the alarm about in the past, including when we were first to report on a still-unexplained series of drone flights near the Palo Verde nuclear powerplant in Arizona in 2019.

  • wolfSSL cryptographic library 5.0.0 Released - LinuxStoney

    A new release of the compact cryptographic library is wolfSSL 5.0.0 now available IoT , optimized for use on embedded devices with limited processor and memory resources, such as devices, smart home systems, automotive information systems, routers and mobile phones. The code is written in C and is distributed under the GPLv2 license.

    The library provides high-performance implementations of modern cryptoalgorithms, including ChaCha20, Curve25519, NTRU, RSA, Blake2b, TLS 1.0-1.3 and DTLS 1.2, which, according to the developers, are 20 times smaller than the OpenSSL implementations. Both its simplified API and a layer for compatibility with the OpenSSL API are provided. There is support for OCSP (Online Certificate Status Protocol) and CRL (Certificate Revocation List) for checking certificate revocation.

  • Keyless signatures for blobs with cosign

    This whole process is called “keyless” signature or ambient credentials via workload identities. The word keyless can be a little bit misleading. It does and does not refer to the existence of a cryptographic key. Implementation-wise, there is a key. Otherwise, the whole private/public procedure would not work. But, on the same time you do not have to provide a secret for generating this key. The process is secretless; at least on the first look. On the second look you will realize that your Identity has become the secret.

    [...]

    Next, we will use the public sigstore instance to generate a new signature via our OpenID and upload it to a public rekor instance. This feature is still experimental. I hope they will release it soon. During the process your browser will pop-up, forward you to the public sigstore instance and ask you for a login. If you login, cosign will use your OpenID to sign the file.

  • Linux Foundation enhances LFX Security platform | IT World Canada News

    The Linux Foundation has enhanced its free LFX Security vulnerability detection toolkit so open-source projects can secure their code and reduce non-inclusive language.

    On Tuesday, the foundation said the LFX Security module now includes automatic scanning for secrets-in-code and non-inclusive language, adding to its existing comprehensive automated vulnerability detection capabilities.

  • 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.

Red Hat Hires a Blind Software Engineer to Improve Accessibility on Linux Desktop

Accessibility on a Linux desktop is not one of the strongest points to highlight. However, GNOME, one of the best desktop environments, has managed to do better comparatively (I think). In a blog post by Christian Fredrik Schaller (Director for Desktop/Graphics, Red Hat), he mentions that they are making serious efforts to improve accessibility. Starting with Red Hat hiring Lukas Tyrychtr, who is a blind software engineer to lead the effort in improving Red Hat Enterprise Linux, and Fedora Workstation in terms of accessibility. Read more
