  • Reactor Oversight Program

- Areas related to maintaining an effective cybersecurity program CDA - critical digital asset PMMD - portable media and mobile devices 3

IMC 0612 Appendix B - Issue Screening Is the performance deficiency More-than-Minor?

If the answer to any of the following questions is yes, then the performance deficiency is More-than-Minor and is a finding. If the answer to all of the following questions is no, then the performance deficiency is minor and is not a finding.

1. Could the performance deficiency reasonably be viewed as a precursor to a significant event?
2. If left uncorrected, would the performance deficiency have the potential to lead to a more significant safety concern?
3. Is the performance deficiency associated with one of the cornerstone attributes and did the performance deficiency adversely affect the associated cornerstone objective? 4

IMC 0612 Appendix B - Issue Screening Defense in Depth considerations

  • Multiple layers of defensive security controls are placed throughout the system with the intent of providing overlapping defenses in the event that a control fails, or a vulnerability is exploited 5

New Cybersecurity Minor Examples

  • Baseline Configuration
  • Ongoing Monitoring and Assessment
  • Removal of Unnecessary Services and Programs
  • Physical Access Control
  • Evaluate and Manage Cyber Risk (Vulnerability Management) 6

Next Steps

  • June 15 - Draft to be shared regional inspectors; comment period closes by June 30
