What security levels exist on Cplant?
The unclassified computers on the IRN have been approved by DOE for the storage and processing of Sensitive Unclassified data. Owners of such data have the responsibility to adequately protect against unauthorized access. Standard UNIX file access permissions are sufficient to protect this data, but users are reminded that it is their responsibility to properly set their file mode bits and umask. Note that most people set their umask to permit public read which is inappropriate for Sensitive Unclassified data. • What file systems are available?
