Hey all, After investigating 11g the other day I came across an interesting issue. During the installation of Oracle 11g and 10g all accounts, including the SYS and SYSTEM accounts, have their default passwords and only at the end of the install are the passwords changed. This means that there is a window of opportunity for an attacker to log into the database server during the install process. Depending upon "which" install options you choose determines the size of the window. Full details for those that are interested can be found here: http://www.davidlitchfield.com/blog/archives/00000030.htm - since I reported this to Oracle on the 3rd of November they've updated their security checklist document: http://www.oracle.com/technology/deploy/security/pdf/twp_security_checklist_ db_database_20071108.pdf Cheers, David Litchfield
