Since 11 September 2001when the terrorist attacks from USA happened, the whole world and the perspective about terrorism have changed. Unfortunately, the phenomenon of terrorism is evolving and the existing networks have strong financing, benefiting of the last technologies. It represents a threat to the security, to the rights, to the freedom of people and to the values of society. National, European and global institutions must fight against terrorism, developing strategies for combating this phenomenon and must invest in technology for adequate tools in order to protect the population and to allow citizens to live in safety. Certainly, the terrorist threat in the EU is very high because terrorist are abusing freedom movement of people and resources. This is the reason why the member states are responsible for combating terrorism and for reducing the vulnerability to attack. The aim of this article is to present the evolution of the terrorism in EU in the last years and the activities of EU institutions in counter-terrorism, including the legislative framework countering financing terrorism and its way of application in the EU member countries. Terrorism cannot be justified, there are no excuses for the terrorist acts, but recruitment and radicalisation for international organizations has grown. Therefore, the risk for terrorist attacks will never be reduced to zero, but the authorities, from the smallest to the highest level must collaborate in order to be able to prevent and to deal with terrorist attacks, providing the right emergency response to the attacks, with minimal consequences for people.
