When government and defense IT professionals are looking for a bona fide, yet simple, security product, they turn to the FiberPlex SFX-SC92DT-3100A Data Diode. These simple plug and play SFPs feature a data diode functionality, which means data only transmits in one direction without the possibility for a return path, while offering outstanding 10-gigabit optic performance.
The SFX-DD modules are high performance, cyber secure modules supporting a host of data rates and distances. Patton's FiberPlex Cyber-SFP Modules are compatible with the small form-factor pluggable (SFP) multisource agreement (MSA). They are RoHS compliant and lead-free.
Data Diodes provide Network Security and Segmentation
Determining where data diodes should be deployed depends on the security goals. If the primary goal is to protect the source network, then the data diode is deployed at the edge of the security border of the source network. The data diode prevents any possibility of an external party hacking into the source network while making data available outside of the source network.
Data Availability
Many believe that remote monitoring cannot be achieved without remote access to systems. However, as previously stated, if remote access is provided via an external two-way connection, then a threat vector is created. By utilizing data diodes, a high-security network, such as an oil and gas refinery, is secured by one-way transfer hardware, preventing all external access. Meanwhile the data required for remote monitoring, backup, or analysis is sent one-way to another network or the cloud, where end users and applications can access it as needed without compromising the integrity of the refinery controls.
Bilateral/Bidirectional Transfers
Despite all of the security benefits of one-way data diode solutions, in many cases, limited bidirectional communication is still necessary for confirmation or command and control. In these cases, the U.S. Department of Homeland Security's guidance advocates using "a single open port over a restricted network path" to severely limit the attack surface. A bilateral solution includes two independent data diode one-way paths that permit a single, round trip session between pre-configured IP addresses: a one-way data transfer solution responsible for outgoing traffic, and another responsible for incoming traffic.
