Predictive Policing – eine kritisch-negative Vorhersage
In diesem Blogpost möchte ich auf die Gefahren, die Predictive Policing verursachen könnte, eingehen wenn es als wissenschaftlich fundiert angesehen und bedenkenlos eingesetzt wird. Predictive Policing bedeutet ‘vorausschauende Polizeiarbeit’ und ist nicht erst seit dem Zehn-Punkte-Plan von Martin Schulz und der SPD ein beliebtes Buzzword im Zusammenhang mit Wohnungseinbrüchen. Dabei wird versucht, bei Delikten Muster…
Human Error in IT failures
With the ever-increasing complexity of artificial systems that aid humans in their daily and work lives, their operation procedures have grown more complicated and the potential for mishandling is higher than ever before. In the IT world, modern systems that must serve hundreds of millions of customers simultaneously and reliably have grown so complex that…
Social Engineering: Firewall-Rules for your brain – Part 2
In the first part of this series you learned which behavioral patterns are usually used to influence humans. Those patterns are the basis of a Social Engineering attack and can usually be detected by a trained person. In the second part we will examine much more sophisticated influencing techniques. Those techniques are very tricky to…
Spying on everyone – Cheap and Simple
Introduction Espionage, or less formally “syping” has become a huge public topic in Summer 2013. Edward Snowden revealed that The American NSA (National Security Agency) and the allied Great Britain GCHQ (Government Communications Headquarters) are surveilling, storing and examing all network traffic in- and outbound the US and Great Britain. The debate covered the Newspapers…
Social Engineering: Firewall-Rules for your brain – Part 1
Humans can be regarded as one of the biggest weaknesses for secure systems. Their interaction with technology and awareness for information security makes them usually the “weak link” for gaining access to enterprise networks and private information. From an attackers point of view the investment of using a human to hack a system is much…
Blockchain – Revolution or hype?
Welcome to our journey through the blockchain, since the emergence of Bitcoin, one of the most trending topics of the global digital village. After reading this blog post, you’ll have a basic understanding of the technology, a wide overview of future use cases and are able to differentiate between realistic potential and hype. In the…
Analyzing text with IBM Watson services on Bluemix
You might have already heard of IBM’s artificial intelligence “Watson”, which beat two former champions of the american television game show “Jeopardy!” back in 2011. What you probably don’t know is that today lots of predefined Watson services are publicy available on IBM’s cloud platform “Bluemix”. These services cover different aspects of AI-backed applications like…
Of Apache Spark, Hadoop, Vagrant, VirtualBox and IBM Bluemix Services – Part 6 – Apache Spark and/vs Apache Hadoop?
At the beginning of this article series we introduced the core concepts of Hadoop and Spark in a nutshell. Both, Apache Spark and Apache Hadoop are frameworks for efficient processing of large data on computer clusters. The question arises how they differ or relate to each other. Hereof it seems the opinions are divided. In…
Of Apache Spark, Hadoop, Vagrant, VirtualBox and IBM Bluemix Services – Part 5 – Spark applications in PIA project
The main reason for choosing Spark was a second project which we developed for the course “Programming Intelligent Applications”. For this project we wanted to implement a framework which is able to monitor important events (e.g. terror, natural disasters) on the world through Twitter. To separate important tweets from others we use Latent Dirichlet Allocation…
Of Apache Spark, Hadoop, Vagrant, VirtualBox and IBM Bluemix Services – Part 4 – Big Data Engineering
Our objective in this project was to build an environment that could be practical. So we set up a virtual Hadoop test cluster with virtual machines. Our production environment was a Hadoop Cluster in the IBM Bluemix cloud which we could use for free with our student accounts. We developed and tested the logic of…
