Discussion

Any operating system providing too much information in error messages risks compromising the data and security of the structure, and content of error messages needs to be carefully considered by the organization. Organizations carefully consider the structure/content of error messages. The extent to which information systems are able to identify and handle error conditions is guided by organizational policy and operational requirements. Information that could be exploited by adversaries includes, for example, erroneous logon attempts with passwords entered by mistake as the username, mission/business information that can be derived from (if not stated explicitly by) information recorded, and personal information, such as account numbers, social security numbers, and credit card numbers.

Check Content

Verify the /run/log/journal and /var/log/journal directories have permissions set to "2750" or less permissive by using the following command:

$ sudo find /run/log/journal /var/log/journal -type d -exec stat -c "%n %a" {} \;
/run/log/journal 2750
/var/log/journal 2750
/var/log/journal/3b018e681c904487b11671b9c1987cce 2750 
 
If any output returned has a permission set greater than "2750", this is a finding. 
 
Verify all files in the /run/log/journal and /var/log/journal directories have permissions set to "640" or less permissive by using the following command: 
 
     $ sudo find /run/log/journal /var/log/journal  -type f -exec stat -c "%n %a" {} \;
