With the number of users who use these iDevices and sync their data using iCloud, it is natural for them to have some questions about iCloud security. The cloud-based storage and backup service was released just half a year ago, together with the iPhone 4S and iOS 5, and has already garnered a lot more than 100 million users. But its speedy rise in popularity and deep integration into Apple’s computer software has resulted in one major question: how secure is it? In accordance with latest Apple news and Robby Gulri, Echoworx’s vice president, iCloud uses the top security practices in the market for example SSL transmission and on-disk 128 bit encryption. He also commends Apple for its recent go on to ban developer access to Unique Device IDs. That’s the great news. Bur the bad news, however, is that if Apple ever planned to, it could view any and all of the iCloud data. Forensic data analysis expert Jonathan Zdziarski points out a fascinating part of iCloud Security:
However, Apple reserves the right at all times to determine whether Content provided by others and has no duty to pre-screen such Content. However, Apple reserves the right at all times to determine whether Content is appropriate and in compliance with this Agreement, and may pre-screen, move, refuse, modify and/or remove Content at any time, without prior notice and in its sole discretion, if such Content is found to be in violation of this Agreement or is otherwise objectionable.”
So how does Apple access your information if iCloud data encrypted? Ars describes that the company “holds the master decryption key” which would allow it to completely decrypt and review any user’s iCloud data if required.
