The application provides a method, system, device and storage medium for disabling remote login of a root account, the method comprising: modifying a remote login configuration file of the root account to reject remote login of the root account; modifying UID and GID of an icfs account to modify the authority of the icfs account to a normal account, and modifying a login file of the icfs account to allow remote login of the icfs account; copying an environment file under a root account directory to an icfs account directory, and modifying the environment file to adapt to the icfs account; and setting the icfs account to allow use of a process management command and restart an sshd service. The application realizes disabling ssh remote login of a root account of a storage server node, and simultaneously realizes ssh remote login of an icfs account of a storage system.

Embodiments of the present application provide a file backup method, device, equipment and computer program product; the file backup method comprises: obtaining a file write request; in the case that the file write request is a file modification request, determining probability information of the file write request corresponding to a ransom behavior; in the case that the probability information is greater than or equal to a preset threshold, then before performing a write operation based on the file write request, copying a request file corresponding to the file write request to a preset protected directory, wherein the protected directory is located in the kernel. In the present embodiment, since the protected directory is located in the kernel, the access permission of the protected directory is higher than the access request of the file write request, so that in the case of write request operation, the file in the protected directory cannot be written, thereby avoiding the ransom operation on the request file, while ensuring the safety and reliability of the information content, further improving the practicability of the method.
