Basically, to explain an orifice tube in Layman’s context, it
is a car’s air conditioning system and is the exact place where the cold
happens. Not all orifice tubes are standard sized and this means that different
model vehicles use different sizes. These tubes are often color-coded for easy
identification.
A vulnerability level of ZERO can never be obtained since all countermeasures have vulnerabilities themselves. For this reason, vulnerability can never be zero, and thus risk can never be totally eliminated.
