The New York Times had an article on the use of iPads by Baltimore Ravens and the Tampa Bay Bucs to replace their playbook. They briefly mention some of the security involved.
The article mentions the following security
1. Device username Password
2. The playbook app also has a separate password.
3. Some data is kept on the team wifi and is only accessible at the practice facility.
4. 256 bit AES encryption for data in transit.
5. Remote wipe capability
6. 3 bad passwords wipes the application
We can presume the app data is encrypted and can’t be synced to the cloud in iOS 5.
Will this be enough to stop Bill Belichick?
