The invention discloses a traffic data tracing method,
system and device for
hacker threat and a medium. The method comprises the steps of obtaining an original traffic
data stream, extracting features of the original traffic
data stream and constructing a traffic
fingerprint; based on the traffic
fingerprint, tracking an
attack path through a first
algorithm, and determining an
attack propagation trajectory through the
attack path; according to the attack propagation trajectory, a second
algorithm is adopted to analyze the similarity between different attack events, and a cross-domain attack behavior is judged; and obtaining an attack source based on the cross-domain attack behavior judgment result and the attack propagation trajectory. According to the method, traffic statistical features and
time sequence features are extracted, features under different frequency components are deeply excavated by applying a
wavelet transform technology, traffic features are comprehensively presented, lightweight Transform model coding is utilized,
feature vector dimensions are efficiently compressed by means of an attention mechanism, the anti-
confusion capability is enhanced, and even if the interference of
encryption, tunnel or
camouflage technologies is caused, the traffic features can be fully represented. And original flow characteristics can be accurately identified, and a foundation is built for
traceability analysis.
