▪ Integrated Windows Authentication

▪ Authentication via a Security Token, for example Windows Azure ACS

▪ X.509 certificates

A.3.2.2. Confidentiality

WCF supports two different encryption mechanisms: Transport Security and Message Security. Transport

security applies security on a point-to-point basis, which means that, for example in an SOA architecture,

security can only be guaranteed until the first hop. Instead, Message Security applies security on a message

level, which means that the actual payload of the message is encrypted. This automatically implies security

on an end-to-end basis, also if the message is being routed through several intermediates.

A.3.3. OPC-UA

OPC Unified Architecture (OPC-UA) is the new technology generation of the OPC Foundation for the secure,

reliable and manufacturer-neutral transport of raw data and pre-processed information from the manufac-

turing level into the production planning or ERP system. With OPC-UA, all desired information is available

to every authorized application and every authorized person at any time and in any place.

A.3.3.1. Authentication

Upon connection establishment, the user identifies himself via:

▪ X.509 certificates

▪ Username / password

▪ or Kerberos
