How secure is ODBC?
Any ODBC sniffer will be able to trace everything from an ODBC perspective. This includes data, usernames, passwords etc. However, if you are using an ODBC driver that provides encryption, you can increase your level of security. Since any front-end tool can effectively connect to and modify your databases, you need to enforce security at the server level. On the other hand, if you use TCP/IP, ODBC security should be the least of your concerns!
