Title: METHOD AND SYSTEM FOR BLOCKING PHISHING OR RANSOMWARE ATTACK
Abstract:
An external attack blocking system includes: a network file server (NFS); and an NFS client installed in a user terminal or a service server, and connected and communicating with the remotely located NFS, wherein, when there is a request from the NFS client to access or open a storage file in the network file server mounted as a network drive on the user terminal or service server, the NFS assesses the conformity of at least one among program information and user information about the user making the access or open request, and blocks access to the access-requested file or provides the open-requested file in a read-only mode to the NFC client when the conformity is determined to be non-conformity on the basis of the assessment.
