Secure Electronic Documents in mobile Devices

You intern at a large hospital around the D.C. area. The hospital has purchased Android tablets for its nurses and doctors to carry patient medical records. However, the security and privacy of those electronic records becomes a big concern. The manager of the mobile technology department asks you to research and recommend a firewall software and an encryption software for the tablets. Your recommendations should include the name of the software, the price (if applicable), a summary of user reviews, and the rationales of recommending them (rather than others). Include all the references you used.
