The Codice dell’amministrazione digitale (CAD) is the Italian legal framework that regulates digital public administration, including electronic documents, digital identity, signatures, preservation, and the conditions under which a file has legal value. It defines how a digital document can be created, managed, and accepted as evidence within administrative processes.
In cybersecurity, the CAD matters because integrity alone is not enough: a file can remain unchanged and still fail to be trusted as an official record if it does not meet legal and procedural requirements. Defenders use the CAD and related AgID guidelines to align technical controls with authenticity, traceability, and admissibility. Attackers, by contrast, may rely on this gap by presenting technically intact files whose origin, authorization, or context is weak or disputed. The CAD helps organizations treat trust as both a security and governance problem.
