"True" is an adjective instead of a noun in this context. The nouns
in this context are "postive" and "negative."

That is mistaken. We are talking about testing for (and perhaps
mitigating) attack packets. A "positive" for our test is "this packet
is an attack packet." Deciding that a packet is not an attack packet
is a "negative". An accurate test or determination that a packet is
or is not an attack packet is a "true positive" or "true negative".
An inaccurate determination by the test is a "false positive" or "false
negative."
