Safety protection of oil/gas pipeline SCADA system by partition

For oil/gas pipeline SCADA system in China, some problems exist, such as absence of related safety protection and management standards and insufficient safety protection measures, which seriously threaten the country's energy security. Therefore, based on the comprehensive investigation of the oil and gas control processes and the current situation of the construction of oil/gas pipeline SCADA system, and according to China's power industry power secondary protection scheme and the relevant safety standards of American Petroleum Institute as well as the related standards of national classified protection of information security, this paper provides a further partition of safety areas, specifies the protection of each safety area and strengthens the protection capability at key safety areas, which forms a multi-layer protection method. The policy of "partition, physical isolation, multi-layer protection, and longitudinal encryption" is proposed for the oil and gas control areas, which helps to strengthen the border security of oil/gas pipeline SCADA system, improve the safety protection capability inside the system and ensure that the core data, control instruction and confidential information not be stolen or destroyed by attackers.
