A Novel Method for Network Intrusion Detection

Algorithm 1

Data preprocessing algorithm.

	Input: raw data file
	Output: fuzzy triadic background (FTBac)
(1)	cfMap ⟵ relationship between intrusion type and number
(2)	for each i ∈ {raw data} do
(3)	for each j ∈ {T} do
(4)	strDS ⟵ Record[i][j]
(5)	end for
(6)	strDS ⟵ Record[i][m] converted by cfMap
(7)	end for
(8)	for i = 1 to n do
(9)
(10)	for j = 1 to m − 1 do
(11)
(12)	end for
(13)	end for
(14)	FTBac ⟵ standardize and normalize FTBac
