Description
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.

Who does this work

8 NICE work roles and 6 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.

Check Text (C-275585r1147805_chk)

Verify that Ubuntu OS configures the "/var/log/syslog" file with mode "640" or less permissive by using the following command: $ stat -c "%n %a" /var/log/syslog /var/log/syslog 640 If a value of "640" or less permissive is not returned, this is a finding.

Fix Text (F-79592r1147804_fix)

Configure Ubuntu OS to have permissions of "640" for the "/var/log/syslog" file by using the following command: $ sudo chmod 0640 /var/log/syslog
