Zero Trust Security – The further development of perimeter security?
Most companies use perimeter security to secure their cooperate applications, services and data from attackers and unauthorised users. This approach includes a cooperate network, where clients, that are part of the network are able to access the applications. This includes attackers that got access to these networks.Additionally more applications are getting shifted from cooperate networks…
Sicherheitssysteme in der Raumfahrt
Disclaimer Die heutige Raumfahrt oder auch allgemein Raumfahrt ist ein sehr komplexes und vielschichtiges Thema. Nicht grundlos werden umgangssprachlich schwierige Themen als “Raketenwissenschaften” bezeichnet. Dieser Artikel möchte nicht die Raumfahrt in ihrer Gänze beschreiben sondern nur einen sehr kleinen Teil im Bereich der Sicherheit beleuchten. Hierfür wurden sich vor allem auf den Start einer Rakete…
Behind the scenes of modern operating systems — Security through isolation (Part 1)
In recent years, since the Internet has become available to almost anyone, application and runtime security is important more than ever. Be it an (unknown) application you download and run from the Internet or some server application you expose to the Internet, it’s almost certainly a bad idea to run apps without any security restrictions…
Corona Warning App
In 2020 many things are different. People work and study from home, wear face masks and are facing restrictions in their fundamental rights. These measures and restrictions were taken to bring the global pandemic under control. More than 800.000 people have died as a result of Covid-19 (SARS-CoV-2) (25.08.2020). “Let’s build an app for it”…
GDPR and Information Security: A practical guide for Startups and small businesses
Let me start with a story. My first contact with GDPR (general data protection regulation) and the topic of information security was during my bachelor throughout an app project. We had set ourselves the goal of uploading the app to Google Play Store by the end of the semester and were thus inevitably confronted with…
IoT security – The current situation, “best practices” and how these should be applied

These items can be found in most households, at least in parts, whether in Europe, America, or Asia. A trend that affects the entire globe and is currently gaining ground, especially in industrialized countries. It seems to be obvious…

Introduction The mysterious dark part of the internet – hidden in depths of the world wide web, is well known as a lawless space for shady online drug deals or other criminal activities. But in times of continuous tracking on the Internet, personalized…
About the Robustness of Machine Learning
In the past couple of years research in the field of machine learning (ML) has made huge progress which resulted in applications like automated translation, practical speech recognition for smart assistants, useful robots, self-driving cars and lots of others. But so far we only have reached the point where ML works, but may easily be…
Mobile Security – How secure are our daily used devices?
Nowadays, the usage of mobile devices has become a part of our everyday life. A lot of sensitive and personal data is stored on these devices, which makes them more attractive targets for attackers. Also, many companies offer the possibility to work remotely, which results in storing confidential business information on private phones and therefore…
Improved Vulnerability Detection using Deep Representation Learning
Today’s software is more vulnerable to cyber attacks than ever before. The number of recorded vulnerabilities has almost constantly increased since the early 90s. The advantage of Deep Learning algorithms is that they can learn vulnerability patterns on their own and achieve a much better vulnerability detection performance. In this Blog-Post, I will present a…
