To ensure the separation of network and information systems, network segmentation can be used. Network segmentation in situations where one-way communication is important, i.e. where information should only flow in one direction, is a task that can be solved in an effective way with the help of data diodes. By using a data diode, you can ensure that the transmission is carried out securely. The integrity or confidentiality of the network is protected by the data diode – whichever is more important to protect.
DDE Technology has considerable experience working with Advenica's SecuriCDS Data Diodes. Both the separation and diode function are based on an optical transmitter and receiver. The design guarantees that no data can pass in the opposite direction, in fact, it is physically impossible! The solution, with its high assurance, protects assets for operators of critical infrastructure such as utility companies, defence, aerospace and space agencies.
In situations where information needs to go in two directions, a different type of solution is required for secure network segmentation. A solution that can effectively filter the information and ensure that the organisation's information policy is followed with every transfer is needed.
Advenica's ZoneGuard is a customisable and at the same time simple solution based on whitelisting of information through information policies. The solution ensures that organisations securely and correctly can exchange information between security domains at different levels.
