ISO/IEC 19790:2012 the security requirements for a cryptographic module utilised within a security system protecting sensitive information in computer and telecommunication systems. This International Standard defines four security levels for cryptographic modules to provide for a wide spectrum of data sensitivity (e.g. low value administrative data, million dollar funds transfers, life protecting data, personal identity information, and sensitive information used by government) and a diversity of application environments (e.g. a guarded facility, an office, removable media, and a completely unprotected location). This International Standard specifies four security levels for each of 11 requirement areas with each security level increasing security over the preceding level.
ISO/IEC 19790:2012 specifies security requirements specifically intended to maintain the security provided by a cryptographic module and compliance with this International Standard is not sufficient to ensure that a particular module is secure or that the security provided by the module is sufficient and acceptable to the owner of the information that is being protected.
