  • Guy [cracks] UZ and allocates accommodation to students, netting US$3000 in the process

    UZ has an online platform where students can apply for accommodation. What the State is alleging is that Martin gained access to the UZ’s computer network and could edit information on that accommodation platform.

    Once he had that access he proceeded to approach students who were seeking accommodation and charged them between US$40 and $60 to secure it. He is said to have done this between October and November 2021. All in all, he allegedly pocketed over US$3000 from the 64 students he offered the service.

  • ZBC suffers power outage disrupting radio & television programming

  • Why Are Authentication and Authorisation So Difficult?

    Once you’ve selected which type of authentication to support, you may also need to pick a specific implementation if it is not a standard. This potentially complicates the end user’s environment if it’s not a match for the other applications in use. This National Security Agency (NSA) guide categorizes specific MFA solutions into the evaluation criteria from the National Institute of Standards and Technology’s (NIST) 800-63 authentication documents and is a very helpful resource for understanding the strength of each solution. If you are less familiar with identity management and all it encompasses, the NIST documentation is an excellent resource to learn more about this complex set of technologies.

  • Simple Things That Are Actually Hard: User Authentication

    And that’s for the most obvious feature that every application has. No wonder it has been implemented incorrectly many, many times. The IT world is complex and nothing is simple. Sending email isn’t simple, authentication isn’t simple, logging isn’t simple. Working with strings and dates isn’t simple, sanitizing input and output isn’t simple.

  • Hidden Certificate Authorities

    The security of encrypted Web traffic depends upon a set of Certificate Authorities (CAs). Browsers and operating systems are configured with a list of CAs that they trust. The system is brittle, in the sense that if any of the multitude of CAs that your browser trusts is incompetent or malign, the security of all your traffic is imperiled. I've written several times on the topic of misbehaving CAs; there is a list of links at the end of the post.

    In Web trust dies in darkness: Hidden Certificate Authorities undermine public crypto infrastructure, Thomas Claiburn reports on an important paper, Rusted Anchors: A National Client-Side View of Hidden Root CAs in the Web PKI Ecosystem by Yiming Zhang et al. This paper looks at what happens when, by fair means or foul, unofficial entries are added to or replace the CAs in the official list that your browser trusts. Below the fold I discuss their findings.

  • 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.
