Atos Worldline - Technology & Products / Engineering / DEP Page: 24/29 Tamper Evidence The intent of the tamper evidence is to provide evidence that an attack has been attempted and may or may not have resulted in the unauthorised disclosure or modification of the sensitive data. The disclosure of an attempted attack could be in the form of physical evidence such as damage to the packaging. (ISO CD 13491) The physical damage must be such so that the device cannot be placed back in service without a high probability of the tampering being detected. (ISO 9564-1:1991(E)) Tamper Resistance The intents of tamper resistance is to block attacks against the information to be protected from unauthorised disclosure or modification by employing passive barriers. (ISO CD 13491) Tamper Response The intent of tamper response is to employ active barriers against attacks at unauthorised disclosure or modification of the protected information. (ISO CD 13491) Third Party s Security Officer The Third Party could develop its own Application Software and being responsible for the distribution of its Application Software, and thus the key management that is linked to it. In this case, the Third Party needs a Security Officer equivalent to the Atos Worldline Security Officer, called the Third Party s Security Officer.
