ADMIN Network & Security May/June 2023

Sharing files is an important topic in team productivity. All employees need reliable access to required information for successful collaboration. Sandstorm is a security-hardened web app package manager built by a community of volunteers to run open source web applications [1]. Sandstorm’s server-side sandboxing lets you isolate documents securely with little to no effect on productivity. Security Risks in Modern Collaboration The trend in IT has been toward microservices. Ever since hardware virtualization became widespread, individual services have run separately on different virtual machines. Although hard disk space has always been comparatively affordable, virtualization comes at the price of memory overhead for a full-fledged operating system that gives you access to the physical resources of the computer through paravirtualized drivers. Modern platforms with container technology, such as Kubernetes, further optimize…

One of the most prominent MinIO features is S3 application programming interface (API) compatibility, which makes it easy to integrate with existing applications and services built for Amazon S3. Since S3 was released in 2006 it has been heavily marketed and has been used by thousands of projects as one of the standard back-end options available. Whenever you use a popular solution that supports various storage back ends, chances are S3 is among them. Similar to S3, MinIO is designed for highspeed, low-latency access to data, making it suitable for use in demanding applications and environments. Mind you, in this case, the overall performance depends on you – especially on the hardware components you choose. Amazon S3 is famous for its high availability (99.99%, or “four nines,” for S3 Standard…

The Microsoft Azure Sphere platform for integrating microcontrollers with the Internet of Things (IoT) includes both the reference architecture for microcontrollers, matching operating systems, and a cloud service that takes care of updates. In this article I help you get started with Azure Sphere. Digitization and Optimization The significant trend of digitization is increasingly determining business life. Economic success often depends on a company’s ability to map and optimize processes in production and logistics. IoT and its professional offshoot, industrial IoT (IIoT), belong in this context as subsets under the digitization umbrella. IoT provides a link between information technology and the physical world, creating the basis on which software and artificial intelligence (AI) can be applied. For AI to acquire data in the physical world, measure and draw conclusions from…

Many project management tools are complex and require large teams. Still, it is unwise for IT departments in small and medium-sized enterprises (SMEs) to do entirely without planning because the benefits massively outweigh the overhead. I look at project management from the theoretical and practical side and, after a brief introduction to the different types of projects, investigate how OpenProject can help IT managers. Project Management An entire industry focusing on project management has established itself in the enterprise sector. Scrum, Kanban, and many other approaches are promoted and sold along with tools and training. Major corporations have project management departments that dispatch their agile coaches to corporate departments on a needs-driven basis. However, project management is largely dead in the water in smaller organizations. SMEs are usually not interesting…
