The intent of this thesis research is to develop a concept/methodology to advance technologies for controls of network accesses to the industrial processes of safety/operation-critical and to contribute to the nuclear process control modernization with improved nuclear operation security and consequently increased nuclear safety and cost savings. This thesis is focused on the security-integrated nuclear process network-access controls for modernizing nuclear operations. This thesis research commenced with assessments of the current states of nuclear processes in the live nuclear generating stations and identified improvements on the current nuclear practices and security concerns of using the network-based intelligent features of modern process controls for nuclear operations. This thesis has created SNP - Security-integrated Nuclear Process, OBAC - Operation Based Access Control, NOAA - Nuclear Operation Access Authentication, CSM - Cost Savings Model, etc. as the fundamental developments for contributions to the nuclear operations modernization with improved operation security and subsequently increased nuclear safety and cost savings in daily nuclear operations. The SNP is to transform the current nuclear practices into network-based nuclear operations that include equipment performance monitoring, nuclear data processing, nuclear equipment control and maintenance. The OBAC is an operation-based access control built upon the core nuclear operations and facilitates the security and quality controls of network accesses to nuclear operations. The NOAA is to provide user security authentication for access to nuclear operation network, which is composed of APP for access pre-access authentication and AQP for access qualification authentication. The CSM is designed for evaluations of the SNP and associated designs in terms of cost savings opportunity. The feasibility and practicality of these new designs are illustrated in the thesis, by analytical and numerical methods. The significance of these new designs is tremendous, resulting in potentially significant cost savings in daily nuclear generation, in addition with increased nuclear operation network security and subsequently the nuclear safety that is priceless.

The intent of this thesis research is to develop a new methodology to improve existing nuclear process in an efficient, precise, and cost-effective way. This thesis presents three new designs: Secure Trilateral Access Control (STAC), Network-Integrated Nuclear Operation (NINO), and network-driven Condition-Based Nuclear Maintenance (CBNM). STAC design has three tiers: Tier-1 ensures security controls of external accesses to the new nuclear network. Tier-2 ensures qualification controls for carrying nuclear operations. Tier-3 ensures qualification controls for nuclear maintenances. NINO design is to increase efficiency of conducting nuclear operations and ensure correctness of executing targeted operations. CBNM design is to increase efficiency and cost savings for conducting nuclear maintenance and schedule maintenance based on equipment conditions to avoid extremely expensive forced outages. Feasibility and practicality of these new designs are illustrated analytically and numerically in the thesis. The significance of these designs is tremendous, resulting in huge nuclear operation cost savings.

Firewalls and network access controls play important roles in security control and protection. Those firewalls may create an incorrect sense or state of protection if they are improperly configured. One of the major configuration problems in firewalls is related to misconfiguration in the access control roles added to the firewall that will control network traffic. In this paper, we evaluated recent research trends and open challenges related to firewalls and access controls in general and misconfiguration problems in particular. With the recent advances in next-generation (NG) firewalls, firewall roles can be auto-generated based on networks and threats. Nonetheless, and due to the large number of roles in any medium to large networks, roles’ misconfiguration may occur for several reasons and will impact the performance of the firewall and overall network and protection efficiency.
