The Agencies and Companies, that in the development of the own activities deal with classified information, must realize secured environment within which operating. Therefore, Centres for Electronic Data Processing (E.D.P.) and classified files are planned and realized, and subsequently ordinary and extraordinary maintenance is assured. In this contest, A.C.S.I. is able to realize all the intervent procedures provided by law in force. Such document provides the subsequent intervent procedures:

• normal method;
• alternative screening method
• COMSEC adaptation method.

Screened rooms with high attenuation make part of the first category; they're constituted by panels covered in both sides with galvanized steel sheet, located on all the environmental surfaces. The door, screening ventilation grills together with filtering of all room inner systems (electrical one, lighting one , data net and telephony, conditioning one, access control, intrusion-proof one, smoke sensor etc.) complete intervent provided by laws.

Alternative screening method provides special material use, constituted by pellicles realized in poyamide 6,6 with coppering and tinning treatment (low cost and medium-high attenuation), enough in the greater part of cases. Such special materials are installed on the walls and on the ceiling of the room, while the floor is covered by thin copper slabs which create an equipotential mass flat. Also for this method it is provided the utilization of the door and of the screening grills and the screening of possible windows besides the filtering of all room inner systems, cited in the previous method.

In particular environmental conditions, besides, it can be sufficient an aimed intervent which provides the filtering of electrical lines oan of other systems which passes through interested room, together with the creation of a secure floor.

A.C.S.I company is able to carry out environmental rilevation of electromagnetic emissions with various levels of deepening, with the aim of determining more appropriate countermeasures to use, without specific employment of screening. Such instrumental surveys are executed also for attesting the screening efficacy and the adequacy of the room to verify, with the observance of the law in force.

Between all the services which A.C.S.I. proposes to its Clients, it's included also the production of all the documentation pertinent to the planning of such Centres, and also more specialistic and onerous one provided by COMSEC normative law.

In the conclusion of Services it's remarkable the ability of A.C.S.I. to supply, subsequently to the delivery of the realized areas, the ordinary and extraordinary maintenance of Hardware and Software pertinent to the electromagnetic emissions.
