Previously the ISM recommended logging network traffic permitted through gateways or attempting to leave gateways. This recommendation has been changed to logging data packets and data flows in order to more explicitly define the types of events that should be logged. Logging these events will facilitate data analysis and flow analysis activities for gateways.

The volume of data transferred across diodes is monitored.
Miscellaneous changes were made to rationale and recommendations throughout the publication to clarify content without changing intent. This included a review from the Guidelines for System Hardening chapter through to the Guidelines for Data Transfers chapter.
2017
Agencies deploying a diode to control data flow in unidirectional gateways should monitor thevolume of the data being transferred.
Control Text Changed. No public explaination.
2015
Agencies deploying a diode to control data flow in uni–directional gateways should monitorthe volume of the data being transferred.
2010
Agencies deploying a diode to control data flow in uni-directional gateways should monitor the volume ofthe data being transferred.
2008
Agencies deploying a diode to control data flow within a one-way gateway should monitor the volume of the data being transferred.
