Default File Security
OSS automatically assigns default permissions to your files and directories when they
are created. To restrict the default permissions assigned to your files, you must
establish a user mask with the umask command. The user mask specifies the
maximum file permissions that can be applied to your files when they are created. You
can execute a umask command at any time during your session so that it applies to
files and directories created later in the same session. Alternatively, a umask
command can be stored in your .profile file so that it is executed automatically at the
start of each session.
.profile File Security
Secure your .profile file so that no other user can change the file or delete it and
substitute a different version of it.
