As part of CIS 5.4.2.6:Ensure root user umask is configured,
We have set umask 027 in both /root/.bash_profile and /root/.bashrc,
which ensures that:
- New files created by the root user will have default permissions
of 640
- New directories created by the root user will have permissions
of 750
According to the control, setting umask 027 in these files is a
secure practice and meets the guideline for ensuring that root
user files and directories aren’t excessively permissive.
