8.5.3 Secure and monitor replication users

and connections

Because replication involves a complex architecture, many of the vendors
use multiple connections and multiple user accounts to manage and per-
form replication. As an example, when you configure SQL Server replica-
tion with a distributor that is separate from the publisher, you need to
configure a remoter distributor password. When you do this, a new SQL
Server user with System Administrator privileges is created with a password
that you assign within the publishing and distribution property editor, as
shown in Figure 8.12. The bottom line is that you now have a new user
with elevated privileges and additional servers connecting to your server
that you need to closely monitor and track.
