Finished objects will correspond to three threat levels: yellow, orange, and red. While the internal security service can evoke the first level only for heightened attention, the latter stands for immediate danger – an attack has already taken place or is about to.
While the interior ministry has found that potential sites that could be qualified as national defense objects number in the thousands, not all of them will be included in the list, and the choice will be made based on likelihood of attacks, their potential effect and estimated damage.
Objects previously classified as likely targets will be added to the new list first, whereas the total number of objects on the list could grow to several hundred in the coming years. It is also possible to designate as relevant to national security parts of buildings, like server rooms, or backup generators. That could be the case regarding major hospitals.
Even though minimum requirements will be laid down for each category, complying with most requirements will be deemed sufficient. The reason for this is that some objects are located in places where not all requirements can be fulfilled. The defense ministry wanted to construct a separate access control building in front of the ministry's main building after Drambjan's attack in 2011, which the Tallinn Cultural Heritage Board did not allow, however, following heritage protection considerations.
The Ministry of Internal Affairs admits that compliance with requirements will result in certain expenses but claims these are not major. However, some agencies might be forced to move. «We do not expect everything to change tomorrow and institutions to drop everything else on their plate. We perceive no need for major additional investments for state agencies: it is largely a matter of cast of mind,» Koort said.
