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/ftp-start-tls.pcap.out | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'tests/result/ftp-start-tls.pcap.out') diff --git a/tests/result/ftp-start-tls.pcap.out b/tests/result/ftp-start-tls.pcap.out index e793099ab..a04ab94c1 100644 --- a/tests/result/ftp-start-tls.pcap.out +++ b/tests/result/ftp-start-tls.pcap.out @@ -1,7 +1,8 @@ Guessed flow protos: 0 DPI Packets (TCP): 10 (10.00 pkts/flow) +Confidence DPI : 1 (flows) FTP_CONTROL 51 7510 1 - 1 TCP 10.238.26.36:62092 <-> 10.220.50.76:21 [proto: 1/FTP_CONTROL][ClearText][cat: Download/7][16 pkts/1744 bytes <-> 35 pkts/5766 bytes][Goodput ratio: 49/66][0.33 sec][bytes ratio: -0.536 (Download)][IAT c2s/s2c min/avg/max/stddev: 1/0 13/4 34/34 13/8][Pkt Len c2s/s2c min/avg/max/stddev: 60/60 109/165 384/566 80/152][Risk: ** Unsafe Protocol **][Risk Score: 10][PLAIN TEXT (Authorized users only.
