SCADA Security Issues and FPGA implementation of AES - A Review

Cyber-attacks from terrorist, national enemies, disgruntled employees are on the rise now on an Oil Refineries, on shore petroleum fields, off-shore Platforms, Oil and Gas Pipe Lines which will have a catastrophic impact on oil production and in turn on economy of the country, it can also cause serious damage to the environment living being, and even human lives. There is a dire need to protect Petroleum Oil & Gas Processing Infrastructures, Chemical Industry, Nuclear Power Stations, Water pumping & Waste treatment Plants, Electric Power Grids by using a Data Security System, similar systems are in place in Australia, Canada, America and other countries. Current trend of SCADA system protection is to perform backups, upgrade incremental capabilities each year without impacting 24/7 operations and train the personnel regularly, whenever up gradation is carried out. SCADA system should be operated over a Utility Intranet and isolated from public Internet by means of Firewalls, and Routers. It should have a protection based on dynamic predictive mechanism rather than reactive.
