Open platform comprehensive safety protection method based on multi-step protection

The invention discloses an open platform comprehensive security protection method based on multi-step protection, and the method comprises the steps: obtaining an extranet data packet, storing the extranet data packet to a block chain, enabling a feature mark of the extranet data packet to pass through a preset data detection distribution rule, and distributing the feature mark of the extranet data packet to a micro-service architecture server, and generating an external network data packet distribution result, calling data corresponding to the external network data packet according to the external network data packet distribution result, bringing the data into the micro-service architecture server for testing, generating a test result, performing privacy calculation on the internal network data and performing data encapsulation to obtain a secure external network data packet, and sending the secure external network data packet to the micro-service architecture server for testing. And sending the secure exter
