Oracle Solaris is a multiuser environment in which all the users who are logged in to a system can read files that belong to other users. With the appropriate file permissions, users can also use files that belong to other users. For more discussion, see Chapter 1, Controlling Access to Files, in Securing Files and Verifying File Integrity in Oracle Solaris 11.2 . For step-by-step instructions on setting appropriate permissions on files, see Protecting Files in Securing Files and Verifying File Integrity in Oracle Solaris 11.2 .
