How can cyberattacks be anticipated in order to boost IT security? The LHS (Laboratoire de Haute Sécurité - High Security Laboratory), a joint platform developed by engineers from the Inria Nancy - Grand Est research center and Loria, hosts an ultra-secure environment for collecting, experimenting and analysing numerous data sets on attempted intrusions and security attacks. It is used by researchers to monitor trends and to identify potential threats as far in advance as possible.
