we describe the methodology for the entire process. Encrypt, decrypt, 
authenticate and insert a message into an image, identify a message from a 
stego image, and retrieve a message from a stego image.

Isolating modules running on PLC software and other components of a 
SCADA system is a promising approach to prevent an attacker from 
spreading malware to other modules or abusing the full functionalities of the 
operating system. In the fourth industrial revolution, conventional PLCs are 
being replaced by Linux-based smart ones. Since, traditional security strategies 
are no longer appropriate, in this paper, we present cyber security solutions 
that can be applied in SCADA systems. 
A SCADA system is a type of process automation system that collects 
data from sensors and instruments in the field, transmits and displays it at a 
central location, and sends control signals to field equipment. SCADA networks, 
in other words, allow for the receipt of data from remote field devices as well 
as the sending of control messages to remote devices from a control station.
