I was sitting around, staring at a computer monitor like normal, and I thought, if I’m not on the RevBlogs every day, there should probably be some security. So I popped in to install the WordFence security plugin. This has got a bunch of nifty features, like a firewall which blocks a lot of anticipated attacks, a brute force blocker, and an automatic malware scanner. This shouldn’t cause you any problems, except that you can get locked out for inputting the wrong password too many times. But your blog admin email should get you back in. Let me know if you run into any snags or problems!
I also updated all the network wide plugins. If you notice anything odd with your sites from that too, let me know.
