This will ensure the safety of the industrial control systems which are highly essential for the infrastructure of a nation as well as its economy.There are various ICS protocols which vary with the different hardware manufacturers such as Honeywell, Siemens, Toshiba, GE, Mitshubishi, etc.
Since many years, this sector has been ensuring security from the attackers through obscurity owing to the unfamiliarity of the attackers with the protocols.The use of industrial control systems is widely prevalent in a wide range of industries across the world such as nuclear power plants, HVAC installations, robotics, doors of prison cells, etc.
Since they deal with the critical infrastructure, it can't be taken down for updating because of which they become vulnerable to threats.People from the conventional IT security background may find the SCADA/ ICS secuity a challenging task because the technologies, modes, and mindset used in the former can't be applied to SCADA or ICS systems which sharply focuses on the protection of the processes.
Any distress on the processes can lead to severe and life-threatening outcomes such as the outage because of which protection of the process is extremely essential.
which makes securing it more challenging as the physical security is quite important in this case.
SCADA hacking is easily possible when a hacker tries to enter into some remote field station.If we look at the past 20 years, we will find that all the SCADA/ICS systems have been using TCP/IP connection to link with the external world.
