Abstract
A network attack defense method is provided. An access request transmitted from a client to a target server is intercepted by at least one processor of a bypass check device. The client is redirected to a target verification server, to perform verification of a verification code on the client. A verification result of the verification of the verification code performed on the client by the target verification server is obtained. The access request sent by the client is forwarded to the target server based on the verification result indicating that client verification is successful.
Claims20
A network attack defense method, comprising:
- intercepting, by at least one processor of a bypass check device, an access request transmitted from a client to a target server;
- redirecting, by the at least one processor of the bypass check device, the client to a target verification server, to perform verification of a verification code on the client;
- obtaining, by the at least one processor of the bypass check device, a verification result of the verification of the verification code performed on the client by the target verification server;
- and
- forwarding, by the at least one processor of the bypass check device, to the target server, the access request sent by the client based on the verification result indicating that client verification is successful.
A network attack defense apparatus, comprising:
- at least one memory configured to store program code;
- and
- at least one processor configured to access the at least one memory and operate according to the program code, the program code comprising:
- interception code configured to cause the at least one processor to intercept an access request transmitted from a client to a target server;
- redirection code configured to cause the at least one processor to redirect the client to a target verification server, to perform verification of a verification code on the client;
- verification result obtaining code configured to cause the at least one processor to obtain a verification result of the verification of the verification code performed on the client by the target verification server;
- and
- forwarding code configured to cause the at least one processor to forward, to the target server, the access request transmitted by the client based on the verification result indicating that client verification is successful.
A network attack defense system, comprising:
- a bypass check device;
- and
- a target verification server,
- the bypass check device being configured to:
- intercept an access request transmitted from a client to a target server;
- redirect the client to the target verification server, to perform verification of a verification code on the client;
- obtain a verification result of the verification of the verification code performed on the client by the target verification server;
- and forward, to the target server, the access request transmitted by the client based on the verification result indicating that client verification is successful;
- and
- the target verification server being configured to:
- perform the verification of the verification code on the client, and return the verification result to the bypass check device.
