This represents a wonderful opportunity for an indirect attack point for a massive
denial of service. An attacker does not have to hit the control systems network; they
only have to hit the Internet service provider.
Wireless Networks
It is tempting in environments like this to use wireless. Although it is resilient, from
a security standpoint, wireless gear is often exceedingly easy to conduct denial of
service attacks. It may not be a good idea to use it for critical networks such as
generic object oriented substation event (GOOSE) applications.
The problem is that there is boilerplate text in most of the IEEE 802 wireless
specications which advocates the use of carrier sense multiple access/
