Network security
If a SN90 system is connected to the ship’s local area network, data security is of vital
importance.
Equipment manufactured by Kongsberg Maritime are frequently connected to the ship's
local area network (LAN). Connecting any computer to a network will always expose
the data on that computer to all other computers connected to the same network. Several
threats may immediately occur:
• Remote computers can read the data.
• Remote computers can change the data.
• Remote computers can change the behaviour of the computer, for example by
installing unwanted software.
Usually, two parameters are used to define the threat level:
1 The likelihood that any remote connection will do any of the above.
2 The damage done if a remote connection succeeds doing this.
Because Kongsberg Maritime has no information regarding the complete system
installation on any vessel, we can not estimate the threat level and the need for network
security. For this reason, we can not accept responsibility for network security. Systems
provided by Kongsberg Maritime are regarded as stand-alone offline systems, even
though they may be connected to a network for sensor interfaces and/or data distribution.
Note
No network safety applications are installed on any Kongsberg Maritime computers.
The computers are thus not protected against viruses, malware or unintentional access
from external users.
Securing the SN90 system itself has no meaning unless there is a policy in place that
secures all computers in the network. This policy must include physical access by trained
and trusted users. The customer/end user of the SN90 system will always be in charge
of defining and implementing a security policy, and providing the relevant network
security applications.
Note
Kongsberg Maritime will not accept any responsibility for errors and/or damages caused
by unauthorized use or access to the SN90.
