Cybersecurity 101: Protecting the Digital Footprint in the Digital Age
In today’s digital age, our lives are increasingly intertwined with the online world. From social media profiles to online banking accounts, we leave a digital footprint that can be vulnerable to cyber threats. Protecting our digital presence and maintaining online privacy is more important now than ever. In this blog post, we’ll go over the basics of cybersecurity and provide practical tips for protecting your digital footprint.
WiFi News – Part 3: New Root, Old WiFi
On May 23, 2023, the server certificate of our authentication server “radius.rz.rwth-aachen.de” had expired. For that reason a new certificate was implemented in the system. In the first post of this blog series we informed you about this.
Now a larger change is coming up: In the future, the new certification instance GÉANT/TCS will be used and replace DFN-PKI Global. As a consequence a new Radius certificate and certification chain will be used. This migration will take place on August 1, 2023.
Eduroam will be affected with regard to registration and configuration. The exact background and what you have to do, to continue using eduroam, we will explain in the following blog post. Read the rest of this entry »
WLAN News – Part 2: eduroam and certificates
The Wi-Fi network eduroam is available on the entire campus of the RWTH Aachen University. If you have already configured eduroam on your mobile devices and chosen an automatic connection, your devices will connect to eduroam in the background. This happens as soon as your devices detect a network with the name eduroam in the vicinity.
Behind a secure connection to eduroam lie certificate structures that guarantee this security. But how exactly do these processes work? In the following blog post, we hope to provide answers to these and other questions.
QR Code Attacks
QR codes have become increasingly popular in recent years and are now used in almost all areas – whether in advertising, retail or public spaces. Especially since the Corona pandemic, QR codes have gained a lot of importance. For example, they made contact tracking in restaurants or contactless ordering in the catering industry possible. Many users appreciate QR codes because of their simplicity and the time they save, as they can be easily captured with a smartphone. At the same time, however, QR codes can also pose a threat to IT security. In this article, we’ll explain what you should always keep in mind when using QR codes.
Multifactor Authentication in IdM Selfservice
IT security is a major and important topic at RWTH Aachen University and the IT Center.
Already in 2021, it was reported that the introduction of multifactor-authentication (Mfa) would provide systems with greater security against unauthorized access.
In order to offer the MFA protection to further services the IdM Selfservice is now equipped with the so-called “MFA Tokenmanager”.
Discontinuation of “Sophos Antivirus” – What You Have to Do Now
Within the framework of an NRW state license agreement, institutions of the RWTH Aachen University can use the virus scanner “Sophos Antivirus” as well as the corresponding management console “Sophos Enterprise Console” free of charge. In addition, members of the RWTH are allowed to use the software privately.
Now the company “Sophos” has discontinued the on-premises variants of its virus scanner as well as the management console “Sophos Enterprise Console” on July 20, 2023. Starting then, these products will no longer be provided with updates by the manufacturer. To find out if and/or how this is relevant to you, continue reading this blog post.
WiFi News – Part 1: New Certificate for the RADIUS Server

ADAM – Active Directory Campaign
The “Managed Service Active Directory” service has been officially discontinued by the end of 2023.
There were several reasons for discontinuing this managed service. Among other things, the additional costs for the users, the high administrative maintenance effort and the insufficient scalability contributed to this decision.
Howevery, the IT Center of RWTH Aachen University already offers its facilities a far more advantageous alternative: the Active Directory for Workplace Management (ADAM for short).
After a three year project and pilot phase, during which the web interface and a security concept were designed, the managed service has now been introduced.
World Backup Day – Back Up Your Data Today!
In an increasingly digitalized world where we create, exchange and store countless pieces of information every day, the topic of data backup is becoming more and more important. We all depend on our data, whether at work, in education or in our private lives. But this valuable information can be lost quickly, for example, due to technical failures, cyberattacks or even human error. The number of incidents in which companies and private individuals suffer data loss is increasing every year. An effective data protection strategy is therefore more important than ever before.
