vulnerable after rooting?

[droidandme]

I am ready to root my phone but just wondering it.
1. Will my phone be vulnerable from attack after rooting? I like to use my banking program.
2. Is it OK with update to 2.2 when available after rooting?
Thanks in advance.

No more vulnerable than it is now.

You will loose root when 2.2 comes out. It'll have to be rerooted.
