With increasing improvements in different areas, Internet control has been making prominent impacts in almost all areas of technology that has resulted in reasonable advances in every discrete field and therefore the industries too are proceeding to the field of IoT (Internet of Things), in which the communication among heterogeneous equipments is via Internet broadly. So imparting these advances of technology in the Power Station Plant sectors i.e. the power plants will be remotely controlled additional to remote monitoring, with no corporal place as a factor for controlling or monitoring. But imparting this technology the security factor needs to be considered as a basic and such methods need to be put into practice that the communication in such networks or control systems is defended against any third party interventions while the data is being transferred from one device to the other device through the internet (Unrestricted Channel). The paper puts forward exercising RSA,DES and AES encrypting schemes for the purpose of data encryption at the Data Link Layer i.e. before it is transmitted to the other device through Internet and as a result of this the security constraints are maintained. The records put to use have been supplied by NTPC, Dadri, India plus simulation part was executed employing MATLAB.

Industrial Control Systems (ICS) which among others are comprised of Supervisory Control and Data Acquisition (SCADA) and Distributed Control Systems (DCS) are used to control industrial processes. ICS have now been connected to other Information Technology (IT) systems and have as a result become vulnerable to Advanced Persistent Threats (APT). APTs are targeted attacks that use zero-day attacks to attack systems. Current ICS security mechanisms fail to deter APTs from infiltrating ICS. An analysis of possible solutions to deter APTs was done. This paper proposes the use of Artificial Immune Systems to secure ICS from APTs.
