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/citrix.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'src/lib/protocols/citrix.c') diff --git a/src/lib/protocols/citrix.c b/src/lib/protocols/citrix.c index 3575d0e08..6a9aa25b9 100644 --- a/src/lib/protocols/citrix.c +++ b/src/lib/protocols/citrix.c @@ -48,7 +48,7 @@ static void ndpi_check_citrix(struct ndpi_detection_module_struct *ndpi_struct, if(memcmp(packet->payload, citrix_header, sizeof(citrix_header)) == 0) { NDPI_LOG_INFO(ndpi_struct, "found citrix\n"); - ndpi_set_detected_protocol(ndpi_struct, flow, NDPI_PROTOCOL_CITRIX, NDPI_PROTOCOL_UNKNOWN); + ndpi_set_detected_protocol(ndpi_struct, flow, NDPI_PROTOCOL_CITRIX, NDPI_PROTOCOL_UNKNOWN, NDPI_CONFIDENCE_DPI); } return; } else if(payload_len > 22) { @@ -57,7 +57,7 @@ static void ndpi_check_citrix(struct ndpi_detection_module_struct *ndpi_struct, if((memcmp(packet->payload, citrix_header, sizeof(citrix_header)) == 0) || (ndpi_strnstr((const char *)packet->payload, "Citrix.TcpProxyService", payload_len) != NULL)) { NDPI_LOG_INFO(ndpi_struct, "found citrix\n"); - ndpi_set_detected_protocol(ndpi_struct, flow, NDPI_PROTOCOL_CITRIX, NDPI_PROTOCOL_UNKNOWN); + ndpi_set_detected_protocol(ndpi_struct, flow, NDPI_PROTOCOL_CITRIX, NDPI_PROTOCOL_UNKNOWN, NDPI_CONFIDENCE_DPI); } return; } -- cgit v1.2.3
