Fix Recommendation

To ensure the default umask controlled by "/etc/profile" is set properly, add or correct the "umask" setting in "/etc/profile" to read as follows:

umask 077

Check Contents

Verify the "umask" setting is configured correctly in the "/etc/profile" file by running the following command:

# grep "umask" /etc/profile

All output must show the value of "umask" set to 077, as shown in the below:

# grep "umask" /etc/profile
umask 077

If the above command returns no output, or if the umask is configured incorrectly, this is a finding.
