Network file systems on Linux present challenging security problems, especially as data moves to the cloud and clustered storage. This presentation will provide an overview of security considerations, focusing on the most popular file system protocol (SMB3), its security features, and areas its integration with Linux security components. Access to storage over these protocols is often encrypted, and relies on other security protocols for authentication, verifying claims and id mapping. Integration with future security protocols will be needed, and also finding better interfaces to map a user's identity among the 4 ways it is represented in Linux (username, POSIX UID, SID, OID). As more data moves to remote storage, the importance of network file system security becomes more critical. This presentation will discuss where we are and areas where additional improvements are needed.
