· Confidencialidad del tráfico de datos
Observación del tráfico de datos (presencia, ausencia, dirección, volumen y frecuencia) en un canal de transmisión para inferir información (ISO-7498-2). Cuando la dificultad de descifrar los datos transmitidos por un canal es grande, este tipo de ataque puede proporcionar interesantes conjeturas sobre los mismos. [Ribagorda:1997]
Inferencia de información a partir de la observación de flujos de
tráfico (presencia, ausencia, cantidad, sentido y frecuencia). [ISO-7498-2:1989]

analysis
Gaining knowledge
of information by inference from observable characteristics of a data flow,
even if the information is not directly available (e.g., when the data is
encrypted). These characteristics include the identities and locations of the
source(s) and destination(s) of the flow, and the flow's presence, amount,
frequency, and duration of occurrence. [CNSSI_4009:2010]
1. (I) Gaining
knowledge of information by inference from observable characteristics of a data
flow, even if the information is not directly available (e.g., when the data is
encrypted).
These
characteristics include the identities and locations of the source(s) and
destination(s) of the flow, and the flow's presence, amount, frequency, and
duration of occurrence. The object of the analysis might be information in
SDUs, information in the PCI, or both. (See: inference, traffic-flow
confidentiality, wiretapping. Compare: signal analysis.)
