SyBard® Diode v3Cross Domain One-Way Data Transfer
File InterfaceTransparent directory based file transfer
SyBard Diode supports multiple file transfer channels with configurable source and target directories, allowing flexible and convenient one-way file transfer between networks.
Traditionally the only way to adequately protect sensitive networks was to separate them from all other networks via an air gap. This solution however lacks any secure, efficient or auditable means of transferring data into or out of the air gapped network.
The SyBard® Diode utilises 1Gb/s fibre optics and sophisticated cryptographic techniques to provide fast, high integrity data transfer between security domains, that is guaranteed to be unidirectional.
SyBard Diode may be deployed to permit low to high domain transfer of, for example, anti-virus or operating system updates. Its guaranteed unidirectional feature providing strong protection of the high domain from data leakage.
Conversely, the diode may be deployed to control the secure release of data from a high domain to a low domain, providing strong protection of the high domain from attacks entering via the low domain.
SyBard Diode exposes a convenient TCP / UDP interface, suitable for integration with third party products, and a file interface providing transparent directory-based file transfer between domains.

Key Benefits• Removes the need for air gaps between systems
• Fast, convenient, guaranteed one-way data transfer between differing security domains
• Transfer data into a higher security network while ensuring its confidentiality
• Transfer data out of a higher security network while protecting its integrity and availability
• Integration with SyBard Sentry guards— content checking directly on the diode platform, reducing hardware requirements
• Utilises COTS hardware to provide a highly reliable, low cost of operation solution
Key Features
Security
• Provides guaranteed unidirectional data flow
• Installs only requisite operating system components
• Requires minimal operating system privileges
Data Integrity
• Implements source-to-target file integrity checking
• Implements source-to-target TCP stream and UDP datagram integrity checking
• Provides email notifications of failed transfers
One-way data transfer into the secure network
One-way data transfer out of the secure network A diode file service may be deployed on each user’s desktop, providing entirely transparent file transfer for multiple users concurrently through a physical diode. Additionally, a single file service may support multiple file transfer
channels.

The ‘core’ data transfer services expose a TCP interface
The ‘UDP Proxy’ and ‘UDP Relay’ services augment the ‘core’ data transfer services. They expose a UDP interface, and may be installed on the diode appliance directly, or on separate physical machines.
Deployment
be deployed concurrently on the local diode appliance, or on
architecture.
