I have a new post up at Weblog Tools Collection that covers several extremely useful plugins for securing your WordPress blog. WordPress is pretty secure, if you keep it updated, but these plugins provide some serious added security with little to no trade-off. Oh, and they’re all free.

For the most part, most blackhats are apolitical criminals – they’re interested in spamming and stealing credit card numbers, not taking down states or harassing journalists. But I could see that changing quick, so if you’re posting anything controversial (right or left) or criticizing the government of any state, you’d do well to spend some time installing some security plugins.
