Infrastructure and Platform Services 

Desigo Fire Cloud Apps utilizes AWS (Amazon Web Services) cloud infrastructure to host its application services, which, along with Siemens Connect gateway, provides an end-to-end solution to unlock new value for customers. AWS provide cloud infrastructure hardware, software and networks to meet the requirements of security-sensitive organizations and are responsible for protecting the global infrastructure that runs all services offered within their cloud. A detailed list of these can be found at:

Authentication, Access Control & Authorization

Authentication is the first step for any user of Desigo Fire Cloud Apps, its aim is simple – to verify the identity of the user. Desigo Fire Cloud Apps uses Siemens ID, a service based on an IDaaS platform (Identity as a Service), which offers authentication services and external identity management services for Siemens applications accessed by partners and customers. The main benefit of Siemens ID is the single sign-on to Siemens applications. This includes the ID administration by the user, a security token service and features an option for multi-factor authentication providing an added layer of security.

Authorization defines the set of actions that the identified user can perform and defines the access to a specific part of the infrastructure resource. Authorization is a security mechanism used to determine user privileges to devices, services, data and application features. Desigo Fire Cloud Apps implements a role-based access control (RBAC), limiting a user to applications and features. Access to sites and devices is limited by organizations and scopes.

Access control is covered by applying both authentication and authorization steps together.

Data Security

Data Encryption-at-Rest - All data stored at rest is encrypted using AWS standard encryption. The AWS encryption conforms with the Federal Information Processing Standard (FIPS) 140-2 standards.
