From 3a087e951d96f509c75344ad6791591e10e4f1cd Mon Sep 17 00:00:00 2001 From: Ivan Nardi <12729895+IvanNardi@users.noreply.github.com> Date: Tue, 11 Jan 2022 15:23:39 +0100 Subject: Add a "confidence" field about the reliability of the classification. (#1395) As a general rule, the higher the confidence value, the higher the "reliability/precision" of the classification. In other words, this new field provides an hint about "how" the flow classification has been obtained. For example, the application may want to ignore classification "by-port" (they are not real DPI classifications, after all) or give a second glance at flows classified via LRU caches (because of false positives). Setting only one value for the confidence field is a bit tricky: more work is probably needed in the next future to tweak/fix/improve the logic. --- tests/result/ssdp-m-search.pcap.out | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'tests/result/ssdp-m-search.pcap.out') diff --git a/tests/result/ssdp-m-search.pcap.out b/tests/result/ssdp-m-search.pcap.out index 5a185c8f2..f5724685e 100644 --- a/tests/result/ssdp-m-search.pcap.out +++ b/tests/result/ssdp-m-search.pcap.out @@ -1,7 +1,8 @@ Guessed flow protos: 0 DPI Packets (UDP): 1 (1.00 pkts/flow) +Confidence DPI : 1 (flows) SSDP 19 1197 1 - 1 UDP 192.168.242.8:42253 -> 192.168.242.255:32412 [proto: 12/SSDP][ClearText][cat: System/18][19 pkts/1197 bytes -> 0 pkts/0 bytes][Goodput ratio: 33/0][90.00 sec][bytes ratio: 1.000 (Upload)][IAT c2s/s2c min/avg/max/stddev: 4999/0 4999/0 5000/0 0/0][Pkt Len c2s/s2c min/avg/max/stddev: 63/0 63/0 63/0 0/0][PLAIN TEXT (SEARCH )][Plen Bins: 100,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0] + 1 UDP 192.168.242.8:42253 -> 192.168.242.255:32412 [proto: 12/SSDP][ClearText][Confidence: DPI][cat: System/18][19 pkts/1197 bytes -> 0 pkts/0 bytes][Goodput ratio: 33/0][90.00 sec][bytes ratio: 1.000 (Upload)][IAT c2s/s2c min/avg/max/stddev: 4999/0 4999/0 5000/0 0/0][Pkt Len c2s/s2c min/avg/max/stddev: 63/0 63/0 63/0 0/0][PLAIN TEXT (SEARCH )][Plen Bins: 100,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0] -- cgit v1.2.3
