4. 4 ISA–The Instrumentation, Systems, and Automation Society Introductions

5. 5 ISA–The Instrumentation, Systems, and Automation Society Suggested Improvements (From Bob Webb: March 19) n General Topics for attention n Additional clarity n Improvements by section n Annexes

6. 6 ISA–The Instrumentation, Systems, and Automation Society Topics for Attention n Make the document of more practical use by providing examples, checklists, etc. n More information on components “attached” to M&CS: l e.g., historians, optimizers, supervisory systems n Personnel and personnel policies l aligned with TR #1

7. 7 ISA–The Instrumentation, Systems, and Automation Society Additional Clarity n Better description or definition of policies, procedures, programs, etc. n More in depth treatment of existing network security functions and features during inventory and assessment phase n Addition of more details on configuration management and change control

8. 8 ISA–The Instrumentation, Systems, and Automation Society Improvements by Section n Section 10.2: Comprehensive treatment of steps to address vulnerabilities n Section 19: Addition of guidance on routine security reporting and analysis n Section 20: Addition of guidance on periodic audit and compliance measures n Section 21: Add guidance on re-evaluation of security countermeasures, when triggered by external events and/or audit and assessments.

9. 9 ISA–The Instrumentation, Systems, and Automation Society Annexes n Annex A: General cleanup n Annex B: More examples and guidance on audit and vulnerability assessment processes l Include checklists as examples l This may be the appropriate place to relocate material from section 9 l Make some general statements about appropriate content n Annex C: Addition of guidance on steps suppliers and consultants should be using to protect themselves and their clients. n Include a typical “business case” as a separate annex

10. 10 ISA–The Instrumentation, Systems, and Automation Society Additional Improvements n Section 6: Developing a program (18 pages) l creating a program vs. extending an existing program (IT and process safety) l policies vs. standards l functional or performance characteristics with security implications n Section 7: Define Risk Goals (1 page) l related to the question of “what’s different” l expand with examples l may be appropriate to combine with section 6, or more appropriately, section 9

11. 11 ISA–The Instrumentation, Systems, and Automation Society Additional Improvements n Section 8: System Assessment (6 pages) l include safety instrumented systems and burner management systems l go back to introduction to make sure that the basic reference model is well described and understood; know the scope n Section 9: Conduct Risk Assessment & Gap Analysis (12 pages) l should the specifics of this section be placed in an annex? current version is 12 pages l focus on general principles in the text

12. 12 ISA–The Instrumentation, Systems, and Automation Society Additional Improvements n Section 10: Select Countermeasures (5 pages) l reference change mgmt in TR1 n Section 11: Procure Countermeasures l build vs. buy l this is where compromises have to be made l the only step listed is “create spec”, but there are other steps, such as evaluate alternatives

13. 13 ISA–The Instrumentation, Systems, and Automation Society Additional Improvements n Section 12: Define Test Plans (3 pages) l x n Section 13: Test Countermeasures l x

14. 14 ISA–The Instrumentation, Systems, and Automation Society Additional Improvements n Sections 14 & 15: Integration Test l x n Sections 16 & 17: Validation Test l x

15. 15 ISA–The Instrumentation, Systems, and Automation Society Additional Improvements n Section 18: Finalize Operations Measures l Management of changes is referenced in 18.3; is this similar to that in 10.3? l section 18.4 says to establish audit frequency; may want frequency not be public n Section 19: Reporting and Analysis l x

16. 16 ISA–The Instrumentation, Systems, and Automation Society Additional Improvements n Section 20: Audit & Compliance l x n Section 21: Re-Evaluation l x

17. 17 ISA–The Instrumentation, Systems, and Automation Society Additional Improvements n Annex C: Supplier Practices l we need to be challenged to “raise the bar” on the security of products offered. l PCSRF is doing this, as is CIDX; do we have to do so also? l How do we hold suppliers accountable? l This topic may be big enough for another working group?

18. 18 ISA–The Instrumentation, Systems, and Automation Society Meeting Schedule and Plans n Regular conference calls l Frequency? l Length?
