Operational Non-Repudiation Threats


Operational non-repudiation threats are those threats that affect the ability to perform non-repudiation of information in the system and may be caused by operational users of the system. The specific threats are listed below in Table 21.

Table 21. Operational Non-Repudiation Threats




Threat Name
