Nutanix OS must define default permissions for all authenticated users so the user can only read and modify their own files.

Setting the most restrictive default permissions ensures that when new accounts are created they do not have unnecessary access.

Verify Nutanix AOS defines default permissions for all authenticated users in such a way that the user can only read and modify their own files using the following command.

$ sudo grep -i umask /etc/login.defs UMASK 077

If the value for the "UMASK" parameter is not "077", or the "UMASK" parameter is missing, or commented out, this is a finding.

1. For AOS, configure the default permissions "UMASK" to "077" using the following command.

salt-call state.sls security/CVM/shellCVM

2. For Prism Central, configure the default permissions "UMASK" to "077" using the following command.

salt-call state.sls security/PCVM/shellPCVM

3. For Files, configure the default permissions "UMASK" to "077" using the following command.

salt-call state.sls security/AFS/shellAFS

4. For AHV, configure the default permissions "UMASK" to "077" using the following command.

salt-call state.sls security/KVM/shellKVM
