In life, sometimes it can be very useful to have a plan B or to keep a backdoor open. But would you leave your house and hide the keys to the backdoor under the doormat? For burglars, this setup would probably be an easy target. In IT as well, so-called backdoors are a very popular target for hackers. However, these backdoors are much more tricky and discreet than an open door or hidden keys under a doormat. Because even when the original breach of security, such as an open window, no longer exists, cybercriminals can still get in and out as they please via the implemented backdoor.

The project Federated Identity Management.nrw (IDM.nrw) aims to implement a federated Identity Management (FIDM). The federation of the local IDM systems of the institutions in North Rhine-Westphalia should enable users to access the services of various universities at any time and from anywhere with just one account.
The IT Center of RWTH Aachen University is in charge of pursuing this goal together with the consortium partners Ruhr University Bochum, University of Duisburg-Essen and Aachen University of Applied Sciences. Read the rest of this entry »

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.
