A Novel Method for Network Intrusion Detection

Algorithm 3

Classification algorithm.

	Input: network connection I and FCTA
	Output: category of I
(1)	Preprocessing the network connection I
(2)
(3)
(4)	for each i ∈ FCTA do
(5)	simValue ⟵ Sim( VC, i )
(6)	Accumulate the similarity by category
(7)	end for
(8)	maxSim ⟵ 0, k ⟵ 0
(9)	for i = 1 to n do
(10)	avgSim ⟵ Avg (each category simValue)
(11)	if avgSim > maxSim
(12)	maxSim ⟵ avgSim
(13)	k ⟵ i
(14)	end if
(15)	end for
(16)	the classification of d ⟵ k
