The Asset Administration Shell (AAS) specification describes in five parts how information is structured and provided in the Asset Administration Shell. The most important innovation is the new specification part 'Part 4: Security'.

With 'Part 4: Security', a standardized 'Access Control Model' is introduced for the first time. It allows fine-grained and differentiated control of access rights to all components of the asset administration shell - from individual properties to complete submodels. Access can be defined specifically for individual users, groups or organizations. Global visibility, restrictions to specific users or user groups, release of selected attributes only and much more are possible. The specification also supports 'access rules' at both registry and repository level, so that sensitive data remains reliably protected.

"The new security specification for the asset administration shell marks a decisive step forward on the way to the industrial implementation of digital twins. With the new Access Control Model, we are creating the conditions for companies to make secure and differentiated decisions about who can see or use which data - and to do so in line with an internationally compatible standard. This controllability is essential to ensure that digital twins do not remain isolated and become a functioning component of networked industrial processes," says Christian Mosch, Managing Director of IDTA.
