Firmware Upgradeability
Endpoint Memory
• At least 5X current requirements
• Recommendation: 4MB RAM, 8 MB Flash Storage
Firmware Integrity
• Robust encryption & signing of firmware code
Upgrade Speed
• Less than one day to upgrade 10m+ endpoints
Powerful Endpoints + High-Performance Network = Upgradeability

Cost of Protection < Value of Data < Cost of Attack
Security
Open standards = robust and secure
Internet Protocol = proven security foundation
Threat model = 20+ years
Network security > endpoint security
Role-based authorizations are critical
