Ensure permissions on /etc/passwd are configured

보통레벨 1자동cos

설명

The /etc/passwd file contains user account information that is used by many system utilities and therefore must be readable for these utilities to operate. It is critical to ensure that the /etc/passwd file is protected from unauthorized write access. Although it is protected by default, the file permissions could be changed either inadvertently or through malicious actions.
