“…Furthermore, we have only mentioned those classifiers that were selected as best classifiers for a study because most of the studies initially tried out multiple classifiers. Considering the reflections from learning type, we classified the classifier structure into four types: base, Amnesia testbed dataset [125] , SQLMAP [126] [S59, S62, S70] Malware/RAT ESET NOD32 [127], Kingsoft [128], Anubis [129], VirusTotal [130], [S1, S41] APT Sysmon Tool [131], Winlogbeat [132] [S79] Overt Channels ZeuS Tracker [133], Waledac [134], Storm [135] [S22, S39] Side Channel PAPI [136] [S8, S63] Steganography F5 [137], Model Based Steganography [138], Outguess [139], YASS [140] [S3, S9, S20] Data dns2tcp [141],BRO [142],Iodine [143], dnscat [144] and Ozymandns [145], [S4, S14, S15, S21, Tunnelling CobaltStrike [146], ReverseDNShell [147] S29, S32, S67, S68,S80] Fig. 10: Analysis of ML Modelling Phase (The number shows the total studies in each category, while the bold number shows total studies in terms of y-axis) that can handle linear, non-linear, high dimensional data [154].…”
