Network Architecture - Nuclear

The Office of the Inspector General audited the network architecture of a nuclear facility to determine if the network architecture and assets in use to support a specific nuclear plant’s business and operational functions are compliant with TVA policies, procedures and identified best practices. In summary, we found TVA management used proven best practices in the design of the corporate physical and wireless networks and the control network. However, we found cabling that was not following manufacturer’s guidelines and several control network device configurations deviated from TVA baselines and industry best practices. TVA management agreed with our findings and recommendations.
