Device Anxiety
Does my connectivity work reliably?
Will I be embarrassed by a hacking scandal?
Do I have all the IoT protocols working?
Will my battery cope with a weak cell signal?
Will I harm the network?
Will I connect in every country I might ship to?

Vulnerable Devices
When you’re designing, maybe you don’t need to build a fortress, but you should at least lock the front door*
*and if you need a fortress, get a professional!

Security for Cellular IoT Devices
4G is much safer than using a public or untrusted Wi-Fi
network. If you don't trust the network, turn off Wi-Fi on your
phone and use 4G. It’s a lot easier to sniff traffic on a Wi-Fi network
than a cell network, and most people aren't lugging around the
equipment to do so.

Security for Cellular IoT Devices
How do you “Lock the Doors”?• Don’t use default credentials• Don’t leave excess services open• Don’t use unsecured Telnet & HTTP• Require complex passwords • Don’t send data in clear text • Don’t store data in clear text• Be careful about Device ID &
Authentication
Secure the communication between the device and/or gateway and the device manager

Ensuring the Doors are Locked
Start with managed remote scanning using state-of-the-art vulnerability techniques
Combine automated scanning withmanual validation and with penetration testing
For demanding applications: Examine cellular and local interfaces Perform code analysis Analyze encryption implementations and
certificate methodologies Ensure firmware updates can’t themselves be
compromised
Engage a team of security specialists to certify your design

Ensuring Battery Life
Measure under all network conditions
Catalog application profiles, such as Active transmit and receive tasks Deep sleep mode Listening window Firmware update “Under attack”
Run each profile against network scenarios Good, marginal and intermittent coverage High and low network loading Exercise the range of DRX/eDRX and PSM
configurations and settings
Highly accelerated profiling provides results in minutes/hours vs. days/weeks
