Operations of electricity power systems have recently become more intricate due to development of microgrids, execution of open access competition, and use of network-controlled devices, etc. Computer networks therefore turn into an integral component of modern power-grid operations. This paper proposes a new utility computer network security management and authentication for actions / commands requests...
Potential effectiveness of cyber-attacks against utility networks using protocol DNP3 would increase rapidly, when DNP3 is employed over TCP/IP, because attacks succeed on the Internet can be used against DNP3. This becomes a critical concern for DNP3 since an outstation may be accessed from multiple masters of external networks. However, commercial Internet security does not provide applicable security...
Power system modernization with increasing operation automation and integration results in growing computer network access. This facilitates cyber-attackers' capabilities to assume control over power system operations that could cause serious blackouts. Security therefore becomes a critical issue for DNP3, a commonly used protocol for power system communications. This paper proposes cyber-security...
