Cybersecurity incidents are stressful, complex in nature, and are frequently not systematically considered in daily tasks. When correctly managed, operational readiness procedures ensure the availability of data required to successfully and quickly recover from a security incident, while lessening the adverse effect. Therefore, protective measures, such as implementation of data diodes, are playing an essential role in defending instrumentation and control (I&C) systems. In addition, applicability of the newest forensic and digital evidence-related standards to the nuclear domain is being evaluated. Results of such evaluation are being considered in the three-dimensional and two-dimensional modeling of cybersecurity relevant assets. The development of the new IEC 63096, downstream standard of IEC 62645, will also support the proposed evaluation and modeling. However, IEC 63096 covers not only forensic and incident management-related security controls but also a broad range of cybersecurity controls. This paper will further explore the security degree-specific selection and overall assignment of forensic-related security controls for the nuclear domain. Results from ongoing prototype developments will be used to demonstrate possible alternative selections and assignments, along with their contribution to different security metrics.

And Control

With gradual increase of requirements for comfort and living environment,braking noise has become one of the issues concerned by people. The research and control to noise has become focus on designing and making braking systems. Based on associated test techniques and analysis theories, the corresponding test, spectrum analysis and coherence analysis are conducted, information about the noise and frequency spectrum is obtained; three-dimensional modeling and finite element calculation are conducted to its constituent components, natural frequency and vibration type figure are obtained. The basis for optimization of brake and reducing noise is provided.
