They provide data flow filtering and physical separation of networks with complete breakage of the TCP\/IP protocol stack.[\/vc_column_text][vc_column_text][\/vc_column_text][\/toggle][toggle color=”Default” heading_tag=”default” heading_tag_functionality=”default” title=”How do PSTgateways work?”][vc_column_text]They are based on two appliances and each of the appliances acts as the communication endpoint in a domain. Its operation is transparent to the nodes with which it communicates. The existence of the other domain is hidden from the participants in the communication.<\/p>\n
\n
\n
\n

The gateway exchanges high-level elements (files, messages, etc.) that are extracted from the application level and transferred to the other domain after applying filtering mechanisms, content control and\/or ‘strong’ authorization of each element to be transferred.<\/p>\n

Administration and monitoring is always performed from the HIGH domain and preferably through a dedicated administration network.<\/p>\n<\/div>\n<\/div>\n<\/div>\n[\/vc_column_text][vc_column_text][\/vc_column_text][\/toggle][toggle color=”Default” heading_tag=”default” heading_tag_functionality=”default” title=”What is a PSTdiode data diode?”][vc_column_text]PSTdiode<\/strong> diodes are hardware<\/strong> diodes based on two appliances, with the corresponding part of the unidirectional communication hardware in each of them, one the transmitter and the other the receiver.
