StrongDisk Pro Basics
StrongDisk Pro methodology is quite easy to understand.
Just imagine having a strongbox with two keys to it.
The first key you keep in your head (this is your password), and the
second one, the external key, contains specially generated binary code.
Access can be gained only when both keys are present (you can, of course,
use only one key, but it is less secure). StrongDisk Pro encrypts all data
(using both your password and external key as an encryption key) and writes
it to a regular file. This file (so-called "disk image file")
can be stored in any folder of any logical disk accessible from Windows.
A driver from the StrongDisk Pro package allows using this file as a separate protected logical disk ("protected disk" further on). For the operating system your protected disks function just as any other disk, e.g. a CD-Rom or a ZIP drive. After mounting a protected disk you can use it as usual, i.e. create folders, store files (e.g. Word or Excel documents),and open these files directly from the protected disk, etc. When data is written to a protected disk, or read from it, it is encrypted/decrypted "on the fly". This happens so fast you will not even notice the difference between a protected disk and a normal logical one. Install StrongDisk Pro today and be sure that no stranger will gain access to data on protected disks while you are away.
You can use external keys to encrypt data on protected disks. An external key contains a special binary key-code, which will be used as a password to access the protected disks. This key-code is created randomly and is very long, thus eliminating the possibility of finding it by brute force. Two types of external keys are supported: a file-key or a trinket-key (a small device where the key-code is stored). A file-key is a normal file, which contains the key-code. It can be stored on a diskette, a CD, or any other removable media. Every time you want to mount a protected disk you have to insert the disk with the file-key into the disk drive. It means that knowing your password is not sufficient to access your data - your file-key is also necessary. The reverse is also true: the file-key does not let the violator to gain access to your data if he does not know the password. Such a combination significantly boosts data security. A trinket-key is basically the same file-key with the single difference that it is stored in a small device specially made to store a key-code and can be worn, for example, on a key ring. StrongDisk Pro supports file-keys and has built-in means to create them. It also supports Rainbow iKey 1000 and Dallas iButton trinket-keys.
Your Laptop Was Stolen!
Thefts of laptops containing sensitive information is becoming especially frequent nowdays. According to Safeware, the leading computer insurance company, a total of 319,000 notebook computers were lost in the US due to theft in 1999, for a total loss of $800 million dollars. If you install StrongDisk Pro on your laptop, your data will not fall into the hands of a stranger, since StrongDisk Pro protects it. Both your password and external key are required to access the data. Moreover, using StrongDisk Pro not only prevents unauthorized access to protected data, but also hampers detection of its very presence. When a protected disk is not mounted, there are no obvious indications to its existence, so a person who does not usually deal with IT will not even know that there is sensitive information inside the laptop.
If there is a sudden threat to data security, you have several ways to protect your data:
a) a pre-set hot key combination will cause emergency dismounting of all mounted protected disks;
b) special features allow deceiving the violators by substituting "dummy" information in place of the "real" information.
StrongDisk Pro can be configured so that those around you will not even know that you are hiding data inside your computer. Using a file-key (or just a password) and running StrongDisk Pro in the invisible mode will leave no visible traces of sensitive information being stored in your computer. In the invisible mode the StrongDisk Main dialog is opened with a hot key.
Irrecoverable File Deletion
If you delete a file by standard Windows means, its contents remains on the disk; the file is just marked as deleted. That is what makes it possible to un-delete files. A special Burner utility comes with the StrongDisk Pro package, and it serves to completely delete files and irrevocably erase data in them. If you have accidentally deleted a file by usual means, you can erase the contents of all free spaces on the given disk. It is impossible to recover the information that was stored in deleted files after the free space is re-erased.
Protecting the TEMP Folder
When you work with your computer, some information is temporarily stored on the hard disk. This adds to the risk that sensitive information will be written there. With StrongDisk Pro you can create a protected TEMP directory and store all the temporary data there. This completely protects you against the possibility of accidentally leaving sensitive written information unencrypted.
It is clear that backup copies of all the important information should be made as often as possible. On the other hand, the more copies there are, the greater the possibility of data leakage. StrongDisk Pro easily deals with this problem. Disk image files can be copied to a CD-ROM, and data will remain encrypted, so that only the owner will be able to access them.
