What steps can you take to make OSX as secure as possible? I mean both secure as in safe from malware and secure in the event of it being stolen or lost? For a while I just had a password prompt set when it returned from screensaver, only the other day did I notice the glaring back door that meant if you simply rebooted you could get in without a password (as this is a separate setting). I'm starting to wonder what other backdoors I'm missing. Right now, my security measures are thus: password required on login/wake, Keychain and all other important settings password protected, all online passwords are handled by Lastpass (Not sure if this makes it much more secure or not), and firewall is on. I also have a Kensington lock to physically lock it to the desk when I'm using it in a library etc. I have ClamAVX as my only real Antivirus/malware protection that I can think of. There are certain things that I don't know how to guard against- such as running a live Linux CD to access data. I've looked into Filevault but heard a lot of stories about it bricking hard drives, and since I'm about to spend about $250 upgrading my macbook with an SSD and new HDD, I'm not sure how I want to risk that. Is there any other way to prevent someone accessing my drives by live CD or simply physically removing the HDD and plugging in a SATA cable? Basically I wan't to Fort Knox-ify my macbook as much as possible. Any advice welcome. Cheers!
