Internet security lessons for IoT
1 like321 views
The document provides 7 lessons for internet security for IoT devices: 1) Assume the internet is untrustworthy, 2) Don't trust people near your devices, 3) Don't trust any user input, 4) Don't assume users will behave securely, 5) Software updates are necessary as things change, 6) Weak points can be exploited, 7) Have others review your security rather than assuming your own work is secure. The lessons emphasize not trusting networks, users, or one's own abilities, and maintaining updates and reviews to address changes over time.
