>C. Security, 1 July 1997</TD

> While NFS is very convenient for installing diskless machines, it
74
provides almost no security. Data is transmitted unencrypted and
75
authorization is solely based on the identity of IP addresses. Anybody
76
who can forge ethernet packets, has full access over any data that is
77
available via NFS. While there are protocol extension that try to
78
address these shortcomings, I am not aware of any solution for Linux
79
based machines. This means, you have to assume that all exported
80
filesystems are freely read- and writable. Bear this in mind when
81
deciding which data you intend to export.
