I have a Chromebook I routinely use for things like e-banking and other things where a security breach would be catastrophic. I've read it is a very secure OS by nature due to its small surface area for attacks. That said, are there any steps I should take to harden my Chromebook? Or is it as secure as it can be right out of the box?

    Secure as far as there is no malware for Chrome OS until today if I am right. Encryption (PGP/GPG), safe browsing, antivirus + firewall, updating software and so one applies to any OS.

For things like e-banking Chrome devices are secure by default. You don't need to do anything special. There is a good overview about the security here, and a hardening guide here. But you should be aware that your Google account is in fact a part of the system so you should protect the account by things like using a strong password and two factor authentication to maximize security.
