The automatic deployment method for improving the remote login safety of the
elastic cloud host comprises the following steps that S1, a PC end initiates a login request to a
system, a remote access
processing module checks whether a port is open or not, if yes, the next step is executed, If not, a data packet is discarded, and the request is ended; S2, the remote access
processing module checks whether the IP of the PC end is in a white
list or not, if yes, the next step is executed, otherwise, the data packet is discarded, and the request is ended; s3, the remote access
processing module informs the PC that the available
authentication protocol is only the secret key; s4, the PC terminal sends the user name and the secret key, and the remote access processing module checks whether the private key and the public key are paired or not and carries out judgment; s501,
pairing the private key with the public key, and establishing connection between the PC terminal and the cloud host; andS502, if the private key is not matched with the public key, the remote access processing module informs the PC of login failure and returns to the step S4. According to the method, safety reinforcement is triggered every time a new cloud host is created successfully, the application is wide, and the expansibility is high.
