Description
SQL Server is capable of providing a wide range of features and services. Some of the features and services, provided by default, may not be necessary, and enabling them could adversely affect the security of the system. Enabling the replication XPs opens a significant attack surface area that can be used by an attacker to gather information about the system and potentially abuse the privileges of SQL Server.
