Measure against instantaneous power failure for IT equipment on vessels

Dear Customers,

Thank you for using our service.

Writing this for your note. In a recent cyber security inspection, there was a case of pointed "measures against instantaneous power failure

of vessels' IT equipment".

Vessels' generators give power to IT devices though, power is shut down instantaneously at following timing, and it is cause of damage sometimes .

    *Switching generators

    *Shifting to land power when docking

A UPS can help for measures in these situations, but not all equipment needs a UPS.

In general, the necessity of UPS installation is designed based on the risk assessment during the construction of the vessel's network. Therefore, it is not obligatory to specify the criteria necessity of UPS in SMS Manuals.

However, if the SMS Manual is requested to specify the criteria, please refer to the following criterion.

Operational Technology (OT)

　In general, manufacturers decide necessity of UPS, and the necessary

   equipment is already installed. The shipowner does not need to take

   any additional measures.

Information Technology (IT)

　(1) Laptops

　　 Laptops do not require UPS as they have built-in batteries.

　(2) Desktop PCs

　　 Desktop PCs are vulnerable with instantaneous power failure and

        require a UPS.

　　 For PCs that are not important for business, UPS can be omitted,

        but in that case, it is recommended writing in a risk assessment record.

　(3) Intelligent router

           (e.g., carrier router such as ORiON Plus, Infinity, Xchange, etc.)

　　Intelligent routers that manage the onboard network and upstream

       communications require UPS.

          (In the case of ORiON Plus, UPS is installed basically.)

　(4) NAS and data servers

　　These devices stock important data and require a UPS.

　(5) HUBs, WiFi-APs

　　 They will reboot when instantaneous power failure happens, and in

       general theory, UPS is not necessary.

　(6) Printers and peripheral devices

　　In general theory, UPS is not necessary.
