2 Problem: Present and growing mobile threats Malware infected as many Android devices as it did personal computers in the second half of last year Malware found in top apps on Google Play Store Over one in three of all Android owners are likely to encounter threats on their device this year Malware records voice, intercepts s, and more, and is not stopped by encryption or antivirus tools Current security measures such as MDMs, security apps, sandboxing, and hypervisors have been wholly ineffective against attackers Possible Unwanted Programs (PUPs), Trojans, Viruses, and other Malware (4K mobile samples/day) Mobile Malware Growth Q Q Q2 Redwall Technologies 2

Our offensive work inspired a new defensive technology Wide variety of systems but mobile got really interesting Containers do not address malware

requirements Hypervisors and RTOSs don't help at the level most attacks occur, and they have high development costs and long times to market

4 Our offensive work inspired a new defensive technology Wide variety of systems but mobile got really interesting Containers do not address malware or data leakage, and apps must be ported to vendorspecific solutions They are, after all, just apps Cloud solutions have extreme connectivity requirements Hypervisors and RTOSs don't help at the level most attacks occur, and they have high development costs and long times to market TrustZone, dual-personas, and virtualization just pour complexity into a second "container," merely moving the problem, and not solving it Redwall Technologies LLC 4

6 The multiple device problem Because we have multiple missions throughout the day And we switch from role to role and theatre to theatre Because we need to separate and protect data at different levels of security And because we had no other practical choice until now Redwall Technologies LLC 6
