The big cat, Lion, has been out of the bag for a while, and even with Mountain Lion slated to come out this Summer, many are still devising strategies to tame it. In particular, there’s been uncertainty about the update to Apple’s encryption solution, FileVault. In the past it wasn’t as fully featured as encryption solutions from Symantec (PGP) and others, but the functionality of those third party products has been faltering due to ‘plumbing’ changes Apple’s made in order to accommodate, new with Lion, FileVault2 – their higher-performance, whole disk encryption solution.
From a security and ease-of-use perspective, when you encrypt the entire hard drive (or ‘disk’), your documents are much safer if your laptop should happen to be lost or stolen. Only user accounts granted access to un-encrypt the computer (which happens just by logging in with your user name and password like normal) can get at the files. However, there is a ‘get out of jail free’ card provided, just in case you forget your password – the Recovery Key, which is a 24-character code that Apple can even store for you.
When using FileVault 2 in Lion, businesses lose several features they would otherwise have with 3rd party whole disk encryption solutions: we’d like to store that key centrally for our company, keep an inventory on which computers are encrypted, and not worry what user account encrypted the computer when we need to re-deploy it for someone else. Apple’s consumer-focused, manual process for storing the Recovery Key doesn’t help us, so Macintosh Operations at Google have stepped onto the scene with a solution: Cauliflower Vest.
Yes, the name is… distinct, but really it’s just an anagram (same letters, different words) for FileVault Escrow, which means storing the FileVault Recovery Key centrally. A big caveat of using this solution is that it relies on a Google Apps account for every employee whose machine you’d like to use FileVault with. Generously, Google’s Mac Ops team took the time and went the distance to allow us to adapt their tool for use with other centralized systems.
Adjusting to the new changes in Lion can be a considerable amount of work for many administrators. 318 has been a reseller for Google Apps and can also build custom solutions that adapt open source products to your businesses needs.
