Für jemanden, der Systementwicklung betreibt und seine Systeme auf dem TravelNotebook mit sich trägt läuft immer Gefahr, dass das Notebook gestohlen wird. Nicht nur, dass ein € 1500 Notebook weg ist auch die ganzen vertraulichen Informationen inkl. Systeme sind dahin.
Truecrypt war bisher immer eine gute Hilfe um Gewisse Dateien in eine Virtuelle Partition zu stecken und diese zu verschlüsseln, was aber ist mit Temp und Swap Files was mit im System installierten Programmen wie Wealth-Lab, Amibroker usw.
Dies ist jetzt mit der Version 5.0 gelöst. Endlich kann man die Systempartition verschlüsseln und das Passwort muss vor dem Start eingegeben werden.
Dazu kommt auch der lang erwartete Mac OSX Support und ein GUI für Linux:
Auszug aus dem ReleaseNotes:
TrueCrypt can on-the-fly encrypt a system partition or entire system drive, i.e. a partition or drive where Windows is installed and from which it boots (a TrueCrypt-encrypted system drive may also contain non-system partitions, which are encrypted as well).
System encryption provides the highest level of security and privacy, because all files, including any temporary files that Windows and applications create on the system partition (typically, without your knowledge or consent), swap files, etc., are permanently encrypted. Windows also records large amounts of potentially sensitive data, such as the names and locations of files you open, applications you run, etc. All such log files and registry entries are always permanently encrypted as well.
System encryption involves pre-boot authentication, which means that anyone who wants to gain access and use the encrypted system, read and write files stored on the system drive, etc., will need to enter the correct password each time before Windows boots (starts). Pre-boot authentication is handled by the TrueCrypt Boot Loader, which resides in the first cylinder of the boot drive.
Note that TrueCrypt can encrypt an existing unencrypted system partition/drive in-place while the operating system is running (while the system is being encrypted, you can use your computer as usual without any restrictions). Likewise, a TrueCrypt-encrypted system partition/drive can be decrypted in-place while the operating system is running. You can interrupt the process of encryption or decryption anytime, leave the partition/drive partially unencrypted, restart or shut down the computer, and then resume the process, which will continue from the point it was stopped.
To encrypt a system partition or entire system drive, select System > Encrypt System Partition/Drive and then follow the instructions of the wizard. To decrypt a system partition/drive, select System > Permanently Decrypt System Partition/Drive.
The mode of operation used for system encryption is XTS (see the section Modes of Operation). For further technical details of system encryption, see the section Encryption Scheme in the chapter Technical Details.
