SSL and login plugins
There are some cracking plugins to help secure login and administration and the pick of the crop can be found in Appendix A. Among these are plugins to assist with the scourge of this area, partially secured page problems.

With reliable tools such as SSL certificates and Apache modules such as rewrite, auth, and access, plugins would ideally be added only as a last ditch help, sometimes assisting full page encryption.
