The document discusses the critical need for minimum firewall placement in SCADA systems due to increasing cyber threats. It highlights how the integration of commercial information technologies has led to security vulnerabilities that endanger industrial operations and human safety. The use of common protocols and operating systems can facilitate better isolation from external attacks.

1. What is, in your opinion, the minimum firewall placement for a SCADA system?
Solution
Supervisory control and data acquisation has a major demand in these recent years on the
commerical information technologies such as ethernet,TCP/IP. There are several network
security problems from the networks and the networks are passed onto the SCADA and putting
industrial production and human safety at risk.
The internet has came with many attacks from widerange in the reacent years there are so many
cyber attacks that takes place that the network that are connected to SCADA systems. The use of
the some common protocols and OS has made the interface easier to isolate from the outside
world. So minimum firewall placement must be necessary for a scada systems
