The Dipartimento delle Informazioni per la Sicurezza (DIS, "Department of Information Security") is a department of the Presidency of the Council of Ministers of Italy, instituted in 2007 as part of the reform of the Italian security services. It is currently headed by Gianni de Gennaro, the successor to General Giuseppe Cucchi, former director of CESIS.
The department is divided into several functional areas. The Central Security Office (Ufficio Centrale per la Sicurezza) deals specifically with administrative protection of state secrets, including the granting or withdrawal of security clearance to individuals and organisations ("Nulla Osta Security"), the Office of the Central Archives (L'Ufficio Centrale degli Archivi) coordinates and manages the data in the possession of the Italian secret services, and the Training School (Scuola di Formazione) is responsible for the training of government and civilian staff.
