BDC Security Issues

We are planning to use BDC to read and probably write to a SQL Server content database on external server. I have heard that there are many security issues that you may run into or should be aware of before setting 开发者_StackOverflow社区up BDC.

has anyone faced or knows any security issues with BDC. Thanks.

Part 8 shows how to use the BDC to write back data - though its a rarely used feature in 2007. There are some more examples here

In MOSS2007, the BDC is read only, not write.
