Abstract
A method is provided for protecting a file server from a ransomware attack. An exemplary method comprises assigning a session identifier to a remote session initiated with the file server, monitoring operations associated with the session identifier, determining whether the operations are suspicious according to a policy, creating a volume-level snapshot of files on the file server, determining that encryption of the data is occurring when entropy of the monitored data is growing faster than the predetermined threshold rate, classifying the remote session as having a calculated degree of danger when the operations match operations contained in previously observed suspicious behavior patterns, interrupting the remote session when a combination of the degree of danger and the entropy is greater than a predetermined threshold value and restoring the data on the file server using the volume-level snapshot to a state prior to the encryption and dangerous activity.
