Whether it’s suspicious activity on the network, compromised user accounts, or acute cyber attacks – every minute counts in an emergency. In order to be able to respond to security incidents at RWTH even faster and more effectively in the future, the IT Center’s Security Operation Center (SOC) has had an on-call service since June 1, 2025.

The internet offers many opportunities – but also risks. One of the lesser known but potentially very dangerous threats in the field of cyber security is typosquatting. But what does this term actually mean? Typosquatting refers to a technique in which attackers attempt to redirect users to fake or unwanted websites. This is usually done by exploiting typos or similar domain names of well-known websites. Instead of the actual website, you end up on a page that looks deceptively similar to the real one or contains completely different, sometimes malicious content.

The Domain Name System (DNS) makes the Internet usable by translating readable names such as rwth-aachen.de into IP addresses. It originated from simple lists of names and developed into a globally distributed, hierarchical system. Today, it fulfils many more tasks – for example in the areas of e-mail, IT security and network management. The DNS also plays a central role at RWTH Aachen University and is protected by modern technologies such as DNS firewalls. This article provides an overview of the origin, structure and current significance of the DNS.
