The invention discloses an internal and external
network security service passing method and
system based on
edge computing, and belongs to the technical field of
network security, and the method comprises the steps: obtaining multi-dimensional attribute information of an
edge node, generating a
security policy basic
data set, generating a traffic feature
fingerprint and a self-
adaptive environment adaptive
fingerprint, and calculating a fusion matching degree; edge security entity nodes are generated in combination with service scene adaptive threshold clustering, and then a
security policy meta-model with a
security policy blueprint as a core is constructed; analyzing the security policy meta-model through a multi-
modal semantic analysis engine, generating a dynamic
security enhancement model, and mapping the dynamic
security enhancement model to a hierarchical security control model; based on the hierarchical model, outputting
edge node internal and external network safety passage configuration and a corresponding safety passage ledger through a scenarized
configuration generation algorithm; according to the method, adaptive generation, dynamic optimization and accurate execution of the security policy are realized, and the security, the
automation level and the operation and maintenance efficiency of internal and external network passing in the
edge computing environment are effectively improved.
