Details
While the system administrator can establish secure permissions for users’ .netrc files, the users can easily override these. .netrc files may contain unencrypted passwords that may be used to attack other systems.
Solution
Making global modifications to users’ files without alerting the user community can result in unexpected outages and unhappy users. Therefore, it is recommended that a monitoring policy be established to report user .netrc file permissions and determine the action to be taken in accordance with site policy.
