Segregation of networks

SEGREGATION OF NETWORKS

Digital infrastructure needs to be able to resist known threats and recover quickly if disaster strikes. One simple and efficient approach to this is to segregate the network into either functional units (such as production and administration) or data classification (such as OFFICIAL and SECRET).

The Oakdoor™ family of data diodes lets organisations safely connect systems and workflows ‘cross domain’, supporting all the security requirements of the most trusted side of the boundary.

The Oakdoor™ Basic Diode enforces a one-way data flow at the network link layer (layer 2), meaning it can create Demilitarised Zones (DMZ) or protect streaming equipment such as cameras and other sensors.

When using network protocols that require acknowledgements of receipt, the Oakdoor™ Basic File Diode acts as an intermediate receiver, maintaining one-way security by passing files securely across the diode while returning the required acknowledgements.

For an added layer of security against malware, the Oakdoor™ Import Diode ensures that structured data coming into the segregated network cannot contain malicious elements. The diode digitally wraps any non-structured data, such as executable programs, rendering it harmless until further inspection of the content can happen. As hardware verifies the data structure, it’s impossible to hack the system and alter the specification or running code.
