A little while back, I took to using the wonders of .htaccess directives to make my WordPress deployments more secure. It does work but has the disadvantage that desktop blog editors like Windows Live Writer, Word 2007 and w.bloggar cannot be used to update your blog. I must have a look at getting around this but I am sticking with using WordPress itself to do the editing for now (Dean Lee’s port of FckEditor for WordPress is working out very well, spurious   codes notwithstanding).
