Overview • Security Requirements • Access Control Specification • Access Control Realization • Security Architecture • Design Concerns • Summary V. Vuppala,Controls DB Meeting
Security Requirements • General • Authentication and Authorization • Role-based access control • Delegation • Structural • Controlled access to components, their attributes and relationships • Area Managers are responsible for structural data • Behavioral or Operational • Controlled access to Operation of the Accelerator • Not managed by area managers • Operations Group responsible for Controls System (CS) • Experimental Group responsible for CS in Experimental Areas • Dynamic Access Control (Check-in/out Model) • Services • Controlled access to application functionality V. Vuppala,Controls DB Meeting
Information Architecture • Application layer • Operator interfaces • High-level applications • Libraries • Service layer • Access to data • Programming Interface • Data layer • Managed data • Instrument data • No direct access V. Vuppala,Controls DB Meeting
Example S2 S1 S3 Services 4. Done 3. Add Log Entry ‘YYY’ to L1 5. caput PS01 10 2. PV is PS01 6. Done 1. What is the PV for XXX? Application V. Vuppala,Controls DB Meeting
Access Specification • Persons, Groups, Roles • Core • Grouping of Components Based on Areas • Areas Associated with Roles • Grouping of Components Based on Operations • Operational Groups Associated with Roles • Develop a Tool to Specify Authorizationand Delegation • Services • Each Application Has Its Own Authorization Data V.

Authorization: Core Structural V. Vuppala,Controls DB Meeting
Authorization: Core Operational V. Vuppala,Controls DB Meeting
Access Control: Realization S2 S1 S3 3. Add Log Entry ‘YYY’ to L1. [Token] 4. Done 5. caput PS01 10. [Token] 2. PV is PS01 1. What is the PV for XXX? [Token] 6. Done Auth Token Credentials V. Vuppala,Controls DB Meeting
Concerns • Channel Access Does Not Support Tokens • Develop a Gateway? • Auth Service • Use Kerberos or Develop New Service • Single Point of Failure: Redundant Servers • Each Service Needs to Provide Security Configuration Tool • No Good Generic Way to Provide Service-Level Authorization • What About Dynamic Access Control? • Develop an Application for Reservation and Release (Check-in/out) V. Vuppala,Controls DB Meeting
Architecture • Authentication/Authorization Service • Ticket Based System • Persons, Groups, Roles • Component Groupings for Core Security Specifications • Service-Level Access Control left to Services • Access Controls on IOCs • Tools • To Specify Core Authorizations • To Specify Service-Level Authorizations • To Reserve and Release Components V. Vuppala,Controls DB Meeting
Summary • Security Must Be Integrated Into Design • Not Very Trivial • No Precedence • Work In Progress V. Vuppala,Controls DB Meeting
