TCP: C2S Ambiguity Mismatching Window in SYN Retrans
This protocol anomaly triggers when it detects a TCP SYN retransmission where the window size did not match the one that was specified with the original SYN. IDP cannot tell the initial window size, as it is unknown whether the server has received the first SYN.
