B. Security
Security in industrial networks bears a strong resemblance
to that of commercial networks due to the growing overlap of
the technologies used in both. While many of the same threats
exist to both networks, the additional requirements and considerations
of industrial networks mean that security may often
be more difficult to implement. The goal of network security is
to provide confidentiality, integrity of information, availability,
authentication, authorisation, auditability, nonrepudiability and
protection from third parties [41]. The lack or loss of these
features can result in a situation where a failure of the network
may occur.
