Abstract
A method for managing access control within a modular automation system including at least two automation modules. Each automation module is associated with an operation or a set of operations for carrying out a specific task. The method includes: receiving a schema of a common process including at least the order of processing steps of the modular automation system, wherein each processing step includes one or more of the specific tasks of the automation modules; generating privilege associations for each processing step with one or more automation modules, based on the schema; and generating an access control policy for the automation modules based on the privilege associations.

A method for managing access control within a modular automation system including at least two automation modules, wherein each automation module is associated with an operation or a set of operations for carrying out a specific task, the method comprising:
- receiving a schema of a common process including at least the order of processing steps of the modular automation system, each processing step having one or more of the specific tasks of the automation modules;
- generating privilege associations for each processing step with one or more automation modules, based on said schema;
- generating an access control policy for the automation modules based on the privilege associations.
An automation security system for a modular automation system including at least two automation modules, each automation module being associated with an operation or a set of operations for carrying out a specific task, the system comprising:
- means for receiving a schema of a common process including at least the order of processing steps of the modular automation system, each processing step having one or more of the specific tasks of the automation modules;
- a data unit configured to generate privilege associations for each processing step with one or more automation modules, based on said schema, and to generate an access control policy for the automation modules based on the privilege associations.
