Plant Modifications Design Engineer/
Senior Embedded Software Engineer
Tech Lead/Responsible Engineer for SIEM (Security Information and Event Monitoring) Cyber Security Plant Modification Team – leadership of a diverse group of contract and direct Duke Energy engineers, both hardware and software, in the day to day technical challenges encountered in finalizing the implementation of the digital information system instrumentation for a ‘one off’ plant cyber security modification. The NRC Cyber Security Plan required Brunswick Nuclear Plant to comply with the Cyber Security Controls of NEI 08-09. NEI 08-09, Rev. 6, requires the site to be able to detect cyber-attacks propagated through the Physical, Wireless Network, Wired Network, Supply Chain, and Portable Media and Mobile Devices attack vectors. The Duke Energy Security Control and Implementation Strategy (SCIS) credits a Security Information and Event Manager (SIEM) for timely monitoring of plant network-connected Critical Digital Assets (CDAs) for cyber-attack. Cyber Security controls require Critical Digital Asset (CDA) event logs to be monitored for auditing purposes; this monitoring only applies to devices capable of event logging. SIEM capability was added to the plant to automatically accomplish this monitoring activity. The plant SIEM was additionally added to communicate with the corporate business network, in order to make SIEM data available to NPS (Nuclear Process Systems) at McGuire Island.
Tech Lead/Responsible Engineer for EP Net Cyber Security Plant Modification Team. Eight to ten member team, consisting of Project Managers, software, hardware and data analysis engineers as well as EP (Emergency Planning) personnel. Plant modification was made in order to comply with the requirements of new NRC cybersecurity regulations, The EP data from ERFIS (Emergency Response Facility Information System) was isolated so that all EP related information is fed through OSI/PI to a new and separate Layer 3 EP Network, EP-NET, functioning similarly to a Demilitarized Zone (DMZ). EP-NET will receive data from the Plant Process Network OSI/PI server, which contains logs of all the ERFIS point history. All data passed flows from ERFIS, to the Process PI Server, to the new Plant EP NET PI Server, and then all data will flow on to the Business Level Systems (Layer 2). Remaining ERFIS workstations were relocated in badged access rooms to restrict access to the Security Level 3 Network system. This Engineering Change was responsible for isolating the EP network and updating the plant defensive architecture to protect against cyber security vulnerabilities.
Cyber security Responsibilities, Duke Energy – I worked with the cyber security team very closely with the above projects in developing a cyber secure plant process network as well as the EP/ERFIS system interfaces. In doing so I performed the following duties. I did assessments of whether or not SSC’s were CDA’s (Critical Digital Assets) or DA’s (Digital Assets) and then furthered the assessments to include whether their governing documents were NEI 08-09 or NEI 10-13 by determining if the asset was Direct, Indirect, BOP (Balance of Plant, or EP and which controls were to be assessed against the devices accordingly. To further protect the assets, I developed PM’s (Scheduled periodic maintenance procedures and work orders) in accordance with the asset’s assessment levels. I also performed cyber secure ‘hardening’ of the devices by virtue of both hardware and software means utilizing plant, corporate and industry policies, procedures and guidelines. In addition, I provided a robust cyber secure design of the interconnection of the hundreds of devices while not affecting the security and performance of the interconnected devices and networks. This involved hardware and communication protocols as diverse as Ethernet, DecNet, RS232, RS485, network switches, firewalls, servers, terminals, etc. I also participated in and helped procure CDA’s via a regimented newly developed procurement process to insure that devices were not tampered with or compromised during the manufacturing process as well as delivery to the plant and during storage in various warehouses. In short, I was heavily invested and involved in virtually all phases of the cyber security process involving DA’s and CDA’s in my projects at the Brunswick Nuclear plant. .
Tech Lead/Responsible Engineer for Unit 1 Fuel Zone Recorder Plant Modification Team – Modification changes the functionality of the Reactor Low Level Indicator and the Reactor Vessel Level Recorder using a measure of the reactor vessel pressure to density compensate the water level indication of both of these instruments thus making level indications on both instruments much more accurate. This Engineering Change adds a new digital paperless recorder for the compensated Reactor Low Level Indicator, the existing Reactor Vessel Level Recorder, is to be replaced with a digital paperless recorder. Additionally, a reactor pressure input will be provided to each of the two new instruments to density compensate the water level indication. Using the pressure measurement to compensate the Fuel Zone Water Level (FZWL) channels provides a marked improvement to the accuracy of the reactor water level indications.
