An entity's adherence to the examples contained within this presentation does not constitute compliance with the NERC Compliance Monitoring and Enforcement Program ("CMEP") requirements, NERC Critical Infrastructure Protection ("CIP") CIP) Reliability Standards, or any other NERC Reliability Standards or rules. While the information included in this material may provide some of the methodology that NERC has elected to use to assess compliance with the requirements of the Reliability Standard, this material should not be treated as a substitute for the Reliability Standard or viewed as additional Reliability Standard requirements. In all cases, the entity should rely on the language contained in the Reliability Standard itself, and not on the language contained in this presentation, to determine compliance with the CIP Reliability Standards. 4

5 Agenda Purpose, Applicable CIP Standards Change and Configuration Management New Developments related to V2 and TFE s Audit Trail Requirements 5

6 Why Good Change and Configuration Management? Differing practices and polices among departments and/or units within departments t Differing documentation practices Managerial visibility and organizational control Risk Management NERC s Interests = Best Interests of Reliability 6

7 Applicable CIP Standards and Rules CIP 003, R6: Change Control and Configuration Management CIP 007: Within Context of Change and Configuration Management Test Procedures Ports and Services Security Patch Management Malicious Software Prevention Security Status t Monitoring i Disposal or Redeployment Documentation Review and Maintenance 7

8 Schedule for Table 3 Entities Requirement Begin Work Substantially Compliant Compliant Auditably Compliant CIP 003, R6 12/31/06 12/31/08 12/31/09 12/31/10 CIP /31/06 12/31/08 12/31/09 12/31/10 8

9 Change Management Documented process of change control Adding, modifying, replacing, or removing Critical Cyber Assets Applies to hardware and software Easy to develop tunnel vision i and focus only on software Links with Configuration Management 9

10 Configuration Management Documented process of change control Identify, control, and document All entity or vendor related changes to Critical Cyber Assets Links with Change Management 10

11 Overview/Explanation Documentation that tracks changes to Critical Cyber Asset hardware or software to include: Adding: adding hardware/software to existing system Modifying: making a change to existing hardware/software Replacing: adding new hardware/software Removing: retire/redeploy hardware/software Configuration management activities to: Identify: when a change needs to be made or has been made Control: approval for changes Document: documentation for the whole process 11

12 Process Summary Items requiring documentation when changed: Process documentation (use good version control) Critical Asset & Critical Cyber Asset List Test environment Patch management Changes to Electronic Security Perimeter (ESP) Changes to Physical Security Perimeter (PSP) Process for identifying and changing g ports and services settings Criteria in the change process: Types of changes Who initiates the changes Who approves the changes Approvals and dates for all auditable items Testing records 12

13 Change Management vs. Configuration Management (One View) Change Management Process and activities undertaken to make changes to CCA s Ex: Applying a software upgrade or adding additional memory to laptop Configuration Management Process and activities iti undertaken to establish and/or make changes to configuration of CCA s Ex: Setting up a new CCA and/or changing configuration of existing CCA such as port activation The documented process must address both 13

14 Testing Why: Ensure that new cyber assets and/or changes to cyber assets (not just CCA) do not compromise CCA serving Bulk Electric System Significant Change: Security patches, service packs, vendor releases/upgrades (including operating systems, applications, databases, etc.) Environment: Test Environment is very important must reflect the production environment Documentation: Test results must be documented (good, bad or neutral) All consistent with generally accepted best practices for change management 14

15 Speaking of that Good change and configuration management practices are just good business Should be viewed as a part of overall control and governance framework CIP Standards have specific requirements, but individual policy and practice may go beyond Manage the risks or they may manage you! 15

16 A Simplified View Change Control and Configuration Management (CIP 003, R6) Test Procedures Asset Management Documentation Review and Maintenance Security Issues and dimpacts (e.g., patch management, virus protection, etc.) Access Review and Maintenance 16

17 The Audit Trail Recall -> Once again, all associated measures, measure documentation ti Documentation emphasizing: Process for change control and configuration management Test procedures, test environment, test results Security & Access issues (Ports & Services, Patch Mgmt, Malicious Software Protection, Security Status Monitoring, Cyber Vulnerability Assessment & Account Management) Disposal or Redeployment Annual review & update of CIP 007 Documentation If changes to systems or controls, documentation needs to be updated within 90 days* 17

18 New Developments 9/30/09 FERC Order changes documentation requirement from 90 days to 30 days for CIP 007, R9. This is effective in April, Also applicable to CIP 006, R1.7, CIP 008, R1.4; and CIP 009, R3 10/12/09 NERC Compliance Bulletin # Addresses Interim Approach to Technical Feasibility Exceptions (TFE s) May be requested for CIP 007, R2.3, R4, R5.3, R5.3.1, R5.3.2, R5.3.3, R6 and R6.3 18

19 Possible Penalties and Sanctions Up to $1 M per day, per violation Violation Severity (level of non compliance) Violation Risk Factors Mitigating factors may reduce penalties and sanctions Quality of compliance program, self-reporting, voluntary corrective actions, etc. Aggravating factors may increase penalties and sanctions Repeat violations, evasion, inaction, unwarranted intentional violations based on economic choice, etc. May potentially impact reputation, rate cases, etc. 19

20 Final Thoughts Always remember the importance of tone at the top and how it influences a culture of compliance Change and Configuration Management Practices are about Risk Management and impact many areas of CIP compliance efforts Compliance is a process, not an event Documentation, documentation, documentation NERC s Interests = Best Interests of Reliability 20
