Provided is a method for training credit thresholds, including: acquiring a plurality of service features from history data of a service operation triggered based on a plurality of IP addresses; hierarchically calculating at least two correlation coefficients for each of the service features; generating, for each of the IP addresses based on the correlation coefficients corresponding to the service features, a credit value indicating the validity of each of the IP addresses; generating an evaluation indicator for the plurality of IP addresses; and determining a credit value corresponding to the evaluation indicator as a credit threshold in response to the evaluation indicator meeting a target condition.

A method for training isolation forests includes: acquiring a plurality of categories by classifying uniform resource identifiers; acquiring sample behavior data by monitoring a behavior of a client from each of Internet Protocol IP addresses in a plurality of IP addresses accessing the uniform resource identifiers under the plurality of categories; encoding the sample behavior data as a sample access vector; and training, based on the sample access vector, an isolation forest for recognizing a web crawler from the client.
