After reviewing a company’s NAS configuration and file system access logs, the auditor is advising the security
administrator to implement additional security controls on the NFS export. The security administrator decides to
remove the no_root_squash directive from the export and add the nosuid directive. Which of the following is
true about the security controls implemented by the security administrator?
A.
The newly implemented security controls are in place to ensure that NFS encryption can only be controlled
by the root user.
B.
Removing the no_root_squash directive grants the root user remote NFS read/write access to important
files owned by root on the NAS.
C.
Users with root access on remote NFS client computers can always use the SU command to modify other
user’s files on the NAS.
D.
Adding the nosuid directive disables regular users from accessing files owned by the root user over NFS
even after using the SU command.
