TMA-FREEBSD-4.5.2.2

Ensure root user umask is configured

YüksekDüzey 1Otomatikfreebsd

Açıklama

The user file-creation mode mask (umask) is used to determine the file permission for newly created directories and files. In FreeBSD, the default permissions for any newly created directory is 0755 (rwxr-xr-x), and for any newly created file it is 0644 (rw-r-- r--). The umask modifies the default FreeBSD permissions by restricting (masking) these permissions. Audit: automated read-only check derived from the CIS audit procedure; it prints "compliant" when the control is met.
