Is everyone falling into the trap of over-securing last week's security problem? Isn't this just like banning water bottles on planes after a failed liquid bomb attack?

Be careful that in our haste to secure the private keys, we ignore easier attacks. The article seems to gloss over an attacker hacking the web server, when in fact that gives them such powers that going on to grab the private key might not even be attempted.

OpenSSL isn't last week's security problem: The code didn't magically get better in a week, and all signs indicate that there are likely more serious issues in the library.

Looking past OpenSSL, C didn't magically become a safe language in a week, either; this approach guards against a real problem in C that is not limited to a single bug in OpenSSL: over-reading off the end of a valid buffer.

How easy it is to hack the server itself really ranges from super simple to extremely hard. Is your target is a home server exposed to the internet, admin'ed by someone who installed apache from following online tutorials? Sure, you're better off just getting root access on the server. However, if your target is a server run by properly trained people who live and breath security practices, your best bet is to use a subtle bug in their stack that escaped their notice, extra bonus if it leaves no audit trail (e.g., heartbleed). I don't think this post is meant for an audience of the former group, but for those of the latter group.

I work at a pretty security conscious company (this might be an understatement, we're pretty big on security), and even as a developer on the inside I'd have to get pretty creative to get access to our production servers.

Yup. But when you have a successful attack you should consider what alternatives you have to make sure that never happens again. You might dismiss them since their cost:benefit might not be favourable. If this works, I doubt many people are going to deploy it by default, since the cost:benefit doesn't pay off for them. But it might pay off for some other people who are really pissed off right now.
