Why? This requires CAP_AUDIT_READ. Just don't give CAP_AUDIT_READ to places you don't want to have read permission. Exactly the same as you don't give CAP_AUDIT_CONTROL to sysadm_r. (If we are giving CAP_AUDIT_CONTROL to sysadm_r and you think that any file protections on /var/log/audit/audit.log are adequate we are fooling ourselves!) > Also, shouldn't we have an audit event for every attempt to connect to this > socket? We really need to know where this information is getting leaked to. We certainly can. What would you like to see in that event? -Eric -- Linux-audit mailing list Linux-audit@redhat.com https://www.redhat.com/mailman/listinfo/linux-audit
