Ensure local interactive user dot files access is configured

SrednjaNivo 1Ručni pregledaix

Opis

USER configuration files in their respective HOME directory e.g. $HOME/.profile, should only be accessible to the owner aka UID of the file. Write access to USER or account configuration files may enable malicious users to steal or modify other user's data, or to gain elevated privileges while read access may reveal secrets.
