30 years experience on top of Unix (and internals).

    Security through obscurity is darker than obscurity,
    there stand equally hidden trapdoors and firewalls,
    there is the kingdom of false security.

comment Root user able to access FileVault 2 encrypted drive
The FV encrypted partition is available to all, until… the end of the legitimate user session. At this logout, the FV partition is unmounted and hence protected. I'd suggest to improve your answer with this point.

comment Is it safe to remove read, write, and execute permissions for 'others' recursively on home directory?
Firewall is another approach of the security. Here the OQ is about protection at the file system level, not at the network one.

comment How do you get system diagnostic files from OS X?
→ Martin: if you still have a 10.6 (I don't), could you please open a Terminal or xterm and enter the following commands: type sysdiagnose ; ls -al /usr/bin/sysdiagnose, to test for its availability.

comment Switching network location under Mavericks without password
networksetup doesn't need any access to your Accessibility preferences. It needs an access to priviledged mode. This can be obtained through 2 methods: interactively asking your password or by using your keychain. I didn't find if networksetup is able to use our keychain.

If you intend to deploy FV on a large scale, take care to collect the recovery keys of any FV partition. Check them, put them in a safe.
