Network security
If a TV80 system is connected to a local area network, data security is important.
Equipment manufactured by Kongsberg Maritime is frequently connected to the vessel's
local area network (LAN). When you connect a computer to a local area network you will
always expose the data on that computer. All other computers connected to the same
network may be able to access your data. 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.
Kongsberg Maritime has no information regarding the complete system installation on
any vessel. Systems provided by Kongsberg Maritime are regarded as stand-alone offline
systems. They are stand-alone 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 TV80 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 TV80 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 TV80.
