Security: Turris, New BSD Router Project Release and PuTTY Has Holes

  • Turris: secure open-source routers

    One of the other things it is doing is creating open-source home routers. It started because CZ.NIC wondered about how safe home users are from network attacks. Are there active attacks against home users? And, if so, how frequent are they and what kinds of attacks are being made? To figure out the answer, the organization created Project Turris to create a secure router that it gave away. These routers would monitor the network and report suspicious traffic back to the project. They also served as endpoints for some honeypots that the project was running.

    CZ.NIC wanted to make the Turris router "the right way", he said, so the organization made it all open source. The router has automatic security updates and users are given root access on the device. It also sported some "interesting hardware", Hrušecký said; it had a two-core PowerPC CPU, 2GB of RAM, and 256MB of NAND flash.

    Based on the information provided by the Turris routers, CZ.NIC researchers started publishing reports about what they were finding. That led some people to ask if they could get the routers themselves, because they felt that other router makers were "not doing things right". That led to the creation of commercial Turris routers: the Turris Omnia (which was reviewed here in 2016) and the upcoming Turris Mox. Those routers will still allow people to participate in the research if they choose to.

    Building the routers with free and open-source software (FOSS) is really the only way to go, he said. The project knew that it was not going to be able to compete with small, cheap routers, so it created routers with lots of capability that would allow them to run lots of different kinds of services. FOSS makes it easy to get started on a project like this because there is lots of available software that can be easily integrated into the OS.

    These routers allow users to do whatever they want and people believe they are more capable than they truly are, Hrušecký said. That means they break things in "really creative ways". Sometimes they will make custom changes, completely outside of the OS framework, which get overwritten with the next automatic update. These are "tricky problems" to handle; the project would not have if it locked its users out. At some "dark moments" he understands why some companies do that.

  • Putty 0.71 Fixes Weakness That Allows Fake Login Prompts

    The latest version of PuTTY SSH and Telnet client adds protection against spoofing the terminal authentication prompt to steal login info. Recently released, the update comes after a 20-month hiatus and fixes a total of eight security issues.

    An attacker taking advantage of this weakness could allow authentication on a malicious server with no password and at the start of the session send the text PuTTY shows when prompting for the private key passphrase.

  • 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.
