Conclusions As technology develops and changes, we have to follow it at the same pace. Security measures that protect the users and the owners of the new media from malicious attacks by cyber crimi- nals, that are almost as dynamic as the evolution of the technology they attack, have to be adopted. To do so, corporations have to in- vest time and money in security awareness and defence measures. The latter have to be resilient in so much that they have to withstand even the most brutal attack, but they must also be sufficiently flexible to be modified in time as the nature of the attacks morph and as the components of the network change and evolve.
