Benefits of Hardware Technology

• Overcoming inherent weaknesses of software- memory, logics, settings
• No need for upgrading or overhauling entire operational systems
• Transmit-only configuration is possible through hardware encryption
• Hardware technologies save costs in the long-run
• Frequent spending on upgrades can be avoided

Mechanism

• Data diodes ensure separation of ‘sender’ and ‘destination’
• Use of physical and electrical separation for foolproof protection from security threats
• Use of LEDs for information transfer
• Use of fiber optic cable as mode of communication across security networks
• Similar to a unidirectional electrical diode with one-way electricity transfer
