Data Security
Secure 128-bit SSL communication
All communications between the backup 4 business Server and your computer are transported in a 128-bit SSL (Secure Socket Layer) channel. Although all your backup files travel through a public network (internet), eavesdroppers have no knowledge of what has been exchanged.
Backups are securely encrypted
All of your files are first zipped and encrypted on your server, with your defined encrypting key before they are sent to the backup 4 business server. To all people but you, your files stored on the backup 4 business server are no more than some garbage files with random content.
We don't keep your encrypting key
The encryption key used to encrypt your data files resides only on your computer and is known only to you. It is never transmitted anywhere across the network. Therefore, although we have access to all the encrypted files you store on the backup 4 business server, we have no knowledge of the content of the data files you store.
Reminder : Please make sure you write down you encryption key in a safe place where it will never be forgotten. Otherwise, you will never be able to recover your backup files
Best encryption algorithm is used
Currently, the algorithm that we are using to encrypt your files is 128-bit Twofish. It is a block cipher designed by Counterpane Labs. It was also one of the five Advanced Encryption Standard (AES) finalists chosen by National Institute of Standard and Technology (NIST). It subjects to frequent public reviews but no known attack against this algorithm has been reported.
Require 8.77 x 1017 years to crack 128-bit encryption
A 128-bit key size has 2128 or around 3.4 x 1038 possible combinations. Even if you have the world’s best super computer, ASCI White, SP Power3 375 MHz manufactured by IBM as of November 2000, it would take 8.77 x 1017years to test all combinations.
To check all combinations on this encryption algorithm, it would take:
3.4 x 1038
-------------- seconds ~ 2.76 x 1025sec
12.3 x 1012
i.e. 876530835323573935 years or 8.77 x 1017 years
Currently ASCI White cannot process as fast as we have described in this formula.
Restrict access to data by IP addresses
You can also restrict access to your backup files by defining which IP addresses can access the data. Therefore, if someone tries to access your data from an IP address not on your defined list, their access will be denied. This additional security ensures backup files are not able to be opened to all locations, even if the username and password are known.
