The present invention discloses a
network security intelligent protection method and
system based on an intrinsic security mechanism, which relates to the field of
network security technology. The main scheme is: real-time monitoring of
network data flow and network flow historical data, respectively calculating the flow
mutation index F m , Protocol Abnormal Index P a and port
abnormality indicator Port a And make anomaly judgments; calculate the comprehensive anomaly index I, preset thresholds to judge the network traffic status, and trigger the inherent security mechanism protection when the network traffic is seriously abnormal; calculate the
risk assessment value R and the rule strength ACL of
access control, and take different measures for network traffic anomalies; detect intrusion prevention systems, calculate detection sensitivity S and current
attack update frequency F new , further calculate the current
network access control policy strength C new , update the network's
access control policy in real time; this method has an inherent security mechanism that can immediately protect against serious anomalies and continuously learn and optimize security protection strategies to adapt to changes in the network environment and new security threats.
