On December 10, 2021, an extremely critical, since trivially exploitable, vulnerability (Log4Shell) in the standard library Log4J became public.

With the year 2021 nearing its end, a whole new year full of possibilities is about to begin. Once again, the time has come for some good resolutions. This year has clearly shown us how essential a good IT infrastructure is. Day after day, huge amounts of data are created, processed and shared, both privately and professionally. But what if this data unexpectedly disappears? While many people may be aware of the danger of data loss, only a few actively take precautions to protect their data from such a loss in a private context. Frequent backups aim to prevent data loss and are an essential aspect of IT security.

Computers have become an indispensable part of our everyday lives. Whether at work or during leisure time, information technology often facilitates our daily lives. Every day and at any time, we surf the internet and provide various institutions with our personal data. Cyberattacks too are becoming more frequent and often cause great damage, not only to the individual user, but also to entire companies and institutions. It is of great importance to protect those sensitive data from being stolen and misused.

IT is all around us. We use it in our free time and at work, both at home and on the road. The possibilities it offers us are almost unlimited. But with these possibilities also comes great responsibility, as the use of IT is not always without risks. Cyberattacks are no longer isolated incidents and can affect anyone. With more attacks, there is a need for more IT security and a higher level of awareness. For this reason, several German universities are campaigning for greater awareness in this field.
In order to raise awareness, several German universities have now joined forces for the second time to organise the IT Security Awareness Days. During this online event series, a total of 24 lectures on the topic of information security will be held from 4 October to 12 November 2021. The following universities are actively involved: TU Braunschweig, TU Darmstadt, Uni Hildesheim, KU Eichstätt-Ingolstadt, Uni Göttingen/GWDG, Uni Marburg, Uni Osnabrück, Leuphana Universität Lüneburg, Uni Duisburg-Essen, Uni Köln. The series of events is open to the public. A registration is not required.

Surfing the Internet is part of our everyday lives. Both in our private lives and at work, we are using the World Wide Web. We visit websites to inform ourselves, to communicate and even to shop.

When surfing, you should therefore critically inspect every website you visit. Just like in the real world, there are safe places on the Internet and places that you should avoid for your own safety. Nevertheless, how can you judge a website correctly and how can you distinguish between a trustworthy and an untrustworthy website? The following criteria should help you!

Dark Data – Data that no one knows about anymore

“Keeping order is not difficult. Cleaning up, on the other hand, is very difficult.” That’s kind of the saying, isn’t it? No matter how you spin the proverb, this principle applies not only to children’s rooms and closets, it also applies to our digital memories, and many people are not yet aware of this. Just because we can’t touch digitized data doesn’t mean it doesn’t waste space or energy. In Germany, around 66 percent of the data held is “dark” and lies below the surface of users’ consciousness. Read this article to find out what this is all about.

“The connection is secure” – These words contain a short but revealing piece of information. A valid certificate for a website indicates if it has a secure connection and sensitive data, such as passwords or bank data, are transmitted in a protected environment – this is also the case with RWTH Single Sign-On. The certificate for sso.rwth-aachen.de has now been replaced, as the existing one expires on July 28, 2021. Have you noticed this?
