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. --- src/lib/protocols/vnc.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/lib/protocols/vnc.c') diff --git a/src/lib/protocols/vnc.c b/src/lib/protocols/vnc.c index 6199cacfc..b949b2063 100644 --- a/src/lib/protocols/vnc.c +++ b/src/lib/protocols/vnc.c @@ -50,7 +50,7 @@ void ndpi_search_vnc_tcp(struct ndpi_detection_module_struct *ndpi_struct, struc || ((memcmp(packet->payload, "RFB 004.", 7) == 0) && (packet->payload[11] == 0x0a)))) { NDPI_LOG_INFO(ndpi_struct, "found vnc\n"); - ndpi_set_detected_protocol(ndpi_struct, flow, NDPI_PROTOCOL_VNC, NDPI_PROTOCOL_UNKNOWN); + ndpi_set_detected_protocol(ndpi_struct, flow, NDPI_PROTOCOL_VNC, NDPI_PROTOCOL_UNKNOWN, NDPI_CONFIDENCE_DPI); ndpi_set_risk(ndpi_struct, flow, NDPI_DESKTOP_OR_FILE_SHARING_SESSION); /* Remote assistance */ return; } -- cgit v1.2.3
