Set Default umask for users

MittelStufe 1Automatisiertsolaris

Beschreibung

The default umask(1) determines the permissions of files created by users. The user creating the file has the discretion of making their files and directories readable by others via the chmod(1) command. Setting a very secure default value for umask ensures that users make a conscious choice about their file permissions. A default umask setting of 077 causes files and directories created by users to not be readable by any other user on the system. Audit: UMASK must be 027 (or the stricter 077).
