CompuDiode

    CompuDiode

    The solution for this security issue is CompuDiode by Compumatica. With CompuDiode access to the PCS systems from the internet is protected which makes attacks from the outside impossible.

    CompuDiode consists of an ‘air gap’ and two NextGen firewalls (CompuWall). An ‘air gap’ is a fiber connection and works as a diode whereby only one traffic direction is possible. The diode separates the two networks from each other which means that the control circuitry (PCS) can reach the internet but not the other way around. Attacks from the outside are not possible anymore.

    To provide an extra secure solution CompuDiode contains two NextGen firewalls, one for each network. The NextGen firewall combines simple management with a high level security and a powerful working due to the security principle: “Everything not explicitly allowed is strictly forbidden.” The responsibility of data control is thus transferred from the employee to the administrator.

    CompuDiode is very suitable for industrial environments, because it is shockproof, works at temperatures between -20° and +55° Celsius, doesn’t contain any fans and has a long life time.

    Different CompuDiodes

    The results of a market survey about the use of a data diode by companies show that companies have different requirements. Due to this survey, Compumatica developed three different CompuDiodes, in order to provide a 'perfect' data diode for each customer.

     

Features

  • Network completely shielded

    With CompuDiode the Process Control Systems are protected against attacks from the outside. The air gap only allows one-way traffic which ensures that the PCS systems are not reachable from the internet.

  • Special proxies

    CompuDiode contains proxies which are specifically developed for industrial environments. These proxies are part of the internal NextGen firewalls.

  • Extra security by firewalls

    In principle, the air gap is sufficient to secure the PCS systems against attacks from the outside. By the addition of two NextGen firewalls two extra controls are applied. Therefore, CompuDiode is extra secure.

  • Security principle firewall

    Security is for Compumatica of ultimate interest. Misconfiguration with security leakages as a result is excluded because the NextGen firewalls in default modus know the following principle: “Everything not explicitly allowed is strictly forbidden.’’

  • Classified networks

    Due to the physical separation of the NextGen Firewalls, CompuDiode can be integrated very well as a separation between unclassified networks and thus forbids the traffic from high to low networks. This is also known as red/black separation.

  • Sustainable solution

    With multifunctional applications, CompuDiode is a sustainable solution. CompuDiode can be installed in many ways and has a long life time. CompuDiode is suitable for mobile, industrial and office environments.

  • Efficient central management

    The control of CompuDiode is very easy. The air gap doesn’t need to be configured and works from the moment when it is connected to two networks. Both firewalls can easily be managed via the web management. 

  • Suitable for industrial environments

    CompuDiode is very suitable for industrial environments because it isshockproof, works at temperatures between -20° and +55° Celsius, doesn’t contain any fans and has a long life time.
