Basics at RWTH: Using the VPN

At RWTH Aachen University, the Virtual Private Network (VPN) provides an important and secure connection to the university network. This connection is secured by encryption protocols such as TLS. VPN ensures that all data traffic – either to the RWTH network or, depending on the configuration, also to the Internet – is routed via a so-called “tunnel”. This tunnel protects the data on its way between your end device and the VPN server, where it is then integrated into the RWTH network. In the “Full Tunnel”, for example, requests from your device for external services appear with an IP address of RWTH Aachen University. In this article, we explain how you can set up and use the RWTH VPN service.
Neural Networks – The Basis of Modern AI

Neural networks are models inspired by the functioning of the human brain. They consist of artificial neurons that process information and communicate with each other. These networks enable machines to learn from data and recognise patterns without any explicit programming for each task. Examples include virtual assistants such as Alexa and Siri, translation tools such as Google Translate and creative AI systems such as ChatGPT. In this article, we will look at how neural networks work, what advantages and disadvantages they have and how RWTH Aachen University uses them.

The time has come! Since April 1, 2025, user certificates (S/MIME) can again be requested in the RA-Portal. After our previous certificate provider, Sectigo, terminated its contract on January 10, 2025, we now have a new provider. The German Research Network (DFN) and GÉANT have contracted a new provider for public-key certificates. The choice fell on the Greek trusted provider HARICA (Hellenic Academic & Research Institutions Certification Authority). HARICA is a certification authority of the Greek university network GUnet, is specially optimized for research institutions and meets the highest security standards.

Backing up important professional or private files, such as texts, images and other documents, is essential. Data loss can have catastrophic consequences, whether caused by technical mishaps, accidental deletion or even hardware theft. Data loss can also be caused by viruses or hacker attacks. Viruses can, for example, encrypt the hard drive and then demand a ransom. Here are some proven strategies and tools to ensure that your data always remains safe and accessible.
