I made a rather reasonable proposal, and received plenty of advice, but the proposal never was vetted. Now the issue of brute force attacks has even received Matt's attention: http://ma.tt/2013/04/passwords-and-brute-force/
On the dozen or so WP sites I manage, wp-login.php is frequently among the top 10 most often accessed pages. Yes, I have removed the admin account. Yes, I have robust passwords. Yes, I have plugins to help. Yes, I am playing whack-a-mole and blocking the IPs one-by-one. But brute force attempts to login are happening at an alarming rate.
Wordpress should include login attempt limiting as part of core:
* Logging into WP is a core feature
* Usernames and passwords are a core part of WP security
* Password strength metering is a core feature
* Limiting guesses is a key way to defend against brute force attacks
Is this the end-all-be-all to WP security? No, of course not.
But much of WP security depends on not being able to get access to privileged accounts. And limiting login attempts is a simple, straightforward, non-invasive way to dramatically improve that security. It has almost no impact on the good guys and virtually eliminates a common exploit path.
Not every WP site allows comments, so having Akismet a plugin makes sense. Many other other plugins make sense as plugins. But logging into WP is an essential facility.
Limiting login attempts should be part of core.
