"Secure, Robust, Reliable"
Offsite Backup Service - Security
Secure 128-bit SSL communication
All communications between SecureYourPractice Off-Site Backup 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.
Backup are securely encrypted
All of your files are first zipped and encrypted with a your defined encrypting key before they are sent to SecureYourPractice Off-Site Backup server. To all people but you, your files stored on Ahsay backup server are no more than some garbage files with random content.
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 combination. Even if you have the world 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.Assuming your have the super computer, ASCI White, SP Power3 375 MHz has 8192 processors which totals a capability of 12.3 teraflops (trillions of operations/second), available to you. Also it just needs one computer operation to test a possible combination (which is already faster than what it can do). To use brute force attack (checking 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
to successfully try all combinations. Let alone ASCI White cannot process as fast as what described here. You can be sure that your data stored on our server is 100% secured.
Restrict access to data by IP addresses
You can also restrict access to your backup files from the set of IP addresses you defined. 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 is not open to all location, even username and password are known.
We don't keep your encrypting key *
The encryption key used to encrypt your files resides only on your computer and is known only to you. It is never transmitted anywhere across the network. If this key is lost, all backup files can never be recovered. Therefore, although we have access to all files you stored on our backup server, we have no knowledge of the content of the files you stored.
* When you purchase the Platinum Level Fully Managed service, "SecureYourPractice" retains the key(s) and secures everything for you.
Reminder: Please make sure you write down your encryption key in a safe place where it will never be forgotten. Otherwise, you will never be able to recover your backup files.
