FileVault in Lion


in Geek stuff, Internet matters, Rants, Security

While the interface changes in Mac OS X Lion are confusing, the whole-disk encryption provided by FileVault is a definite step forward.

People who have their laptops stolen and then find their confidential documents posted all over the internet really have no excuse. If it is sensitive, it should be encrypted – especially if it is on a portable device that cannot be wiped remotely.

I hope a future release of iOS includes comparable whole-disk encryption capabilities. iPhones and iPads are even easier to lose than laptops.

Full Disk Encryption Hard For Law Enforcement To Crack

“[T]here are three main problems with full disk encryption (FDE): First, evidence-gathering goons can turn off the computer (for transportation) without realizing it’s encrypted, and thus can’t get back at the data (unless the arrestee gives up his password, which he doesn’t have to do); second, if the analysis team doesn’t know that the disk is encrypted, it can waste hours trying to read something that’s ultimately unreadable; and finally, in the case of hardware-level disk encryption, tampering with the device can trigger self-destruction of the data. The paper does go on to suggest some ways to ameliorate these issues, but ultimately the researchers aren’t hopeful: ‘Research is needed to develop new techniques and technology for breaking or bypassing full disk encryption.'”
