  • What does the Product Security and Telecommunications Infrastructure bill mean for me?

    The UK’s Department for Culture, Media and Sport (DCMS) introduced a bill to Parliament yesterday. But what does that mean for IoT manufacturers and consumers?

    First, this bill has been a long time coming. Many people have been lobbying and working hard to create it. Industry and others with vested interests had to be consulted, draft guidance had to be produced and then acceptable wording had to be agreed.

    Numerous researchers including us have been exposing and drawing attention to poor smart product security too.

    I’ve expressed concern along the way at attempts from industry to water it down, but the bill as it stands is a good first step towards enforcing IoT security.

    [...]

    Banning default passwords will help mitigate issues such as the problem with Sky routers we exposed recently.

  • Book Review: Designing Secure Software

    Designing Secure Software (Amazon, No Starch Press) by Loren Kohnfelder is one of the latest entries in No Starch Press’s line of security books. This book stands out to me for two big reasons. First, this is one of the most mindset-centric books I’ve seen (which means it is likely to age better than a lot of more technically-specific books). Second, this book caters to developers more than security professionals (but don’t take this to mean it’s only for developers), which is definitely a distinguishing feature from so many other security books.

  • 4 Certificate Authorities to use with Let's Encrypt SSL certificates

    It’s obvious from the foregoing that I’m not in favor of the switch to the ZeroSSL CA as the default, so which of the other three would I recommend? I still use the Let’s Encrypt CA, but Buypass’s certificates have a longer lifetime – 180 days, compared to 90 days for the other CAs. When next I have to issue a new certificate or renew an existing one, I wouldn’t mind specifying Buypass as the CA.

  • 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.
