The title of the 13th conference on web security SECURE 2009 organised by NASK and the CERT Polska team affiliated with NASK reflects the “hot” issues related to the possibilities of filtering the traffic and blocking access to harmful content on the Internet.

A great interest shown by firms in the possibility to place their devices in an easily accessible and safe collocation centre induced the NASK to invest in the construction of a modern data centre located in a central point of Warsaw. This is already a third object in which the NASK offers space to be leased together with accompanying services – the other two operate in the Warsaw districts of Kabaty and Ursus.
