Security Issues using DTS package to refresh remote/DMZ website

Hello,

Can anyone explain the security issues involved with using a DTS
package to transfer sensitive data (bank info is encrypted, but other
customer info is sensitive) from a SQL Server on our internal network
to a SQL Server on our DMZ?

We use SQL Server 2000 SP4 on Windows 2000.

Let me know if you need more details.

Thank You,

Jeremy
