Security: Struck by a Thunderbolt, Linux 5.1 Livepatching, Protection Poker, NSA's Ghidra and Arrest for 'Bad' Code

Security
  • Struck by a Thunderbolt

    Such ports offer very privileged, low-level, direct memory access (DMA), which gives peripherals much more privilege than regular USB devices. If no defences are used on the host, an attacker has unrestricted memory access, and can completely take control of a target computer: they can steal passwords, banking logins, encryption keys, browser sessions and private files, and they can also inject malicious software that can run anywhere in the system.

  • Linux 5.1 Livepatching Lands Atomic Replace / Cumulative Patches Support

    With the in-development Linux 5.1 is a big step forward to the kernel's live-patching infrastructure for this functionality that allows primarily applying security updates against the running kernel without the need for reboots.

    The big step forward with Linux 5.1 live-patching is now the ability to properly handle "cumulative patches" or a series of patches that depend upon the prior patches, which can now be properly handled with the infrastructure's new atomic-replace functionality. This eases the roll-out of live patches implemented over the course of multiple patches with ordering/stacking and also recovering performance for functions no longer being patched.

  • Protection Poker: An agile game for mitigating risk

    Unfortunately for the security of our applications, we usually don't "build security in" with development; instead we wait until the last possible moment and slap in security measures, typically forming a police-type security department and creating adversarial feelings between the security folks and the developers.

    There are lots of great security resources, ranging from tools for DevOps teams to thoughtful analysis of how DevSecOps is changing security. It all boils down to where in your development cycle you do security. If your team is implementing a shift-left approach, you already know security needs to be top of mind before any code is written.

  • NSA Open Sources Ghidra For Linux, Windows, Mac — A Powerful Reverse Engineering Tool

    It’s not a hidden fact that the National Security Agency (NSA) develops and uses many powerful and in-house security tools for carrying out different “important” tasks. Ghidra is one such well-known software reverse engineering toolkit that the agency has been using for a long time.

    At 2019’s RSA security conference, the NSA open sourced the tool with Apache 2.0 license, calling it a “contribution to the nation’s cybersecurity community.”

  • 13-Yr-Old Girl Arrested In Japan For Posting Infinite Loop Code

    Japanese police have apparently arrested a 13-year-old girl for “copy-pasting” a link to an infinite loop code.

    The teenager who studies in a junior high school in Kariya-shi, Aichi Prefecture, was arrested by the Hyogo Prefectural Police Department — because they found the girl guilty of posting an “unlawful program” on the internet.

  • 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.
