Only authorized personnel should be aware of errors and the details of the errors. Error messages are an indicator of an organization's operational state or can identify the operating system or platform. Additionally, Personally Identifiable Information (PII) and operational information must not be revealed through error messages to unauthorized personnel or their designated representatives. The structure and content of error messages must be carefully considered by the organization and development team. The extent to which the information system is able to identify and handle error conditions is guided by organizational policy and operational requirements.
Verify the /var/log directory access permissions are set to "755" or less and restricted to "root" using the following command. $ sudo stat -c "%a %n" /var/log 755 /var/log $ sudo stat -c "%U" /var/log root $ sudo stat -c "%G" /var/log root If group ownership of /home/log/messages is anything other than "root", this is a finding.
Nutanix OS VMs are configured by default to have ownership and permission levels set correctly to meet this requirement. If these are found to be out of compliance, some corruption has taken place and the OS must be rebuilt.
