• Choose SoC that is fit for the purpose

• Amend SoC with additional chips that are

needed for required security level e.g.

tamper protection, secure key storage

• ”Blow the fuses” to prevent unauthorized

debugging and firmware access

• Apply proper enclosure/casing

SUMMARY

• BYOD concept encourages use of personal devices for work

• But: as we have seen BYOD doesn’t really work for public safety

• Special requirements call for specialized devices

• Procurement model vs. mobile device ecosystem & processes

• How about using your professional device for personal use?

Thank You!
