Questions tagged [security]

For questions relating to the security of IoT devices (especially those connected directly to the internet) and how to mitigate these issues or avoid them altogether. Do not confuse this with device safety (If it gets hacked it's a security question, if it explodes it's a safety question).

Use this tag for questions that are about the security of IoT devices (especially those connected directly to the internet) and how to mitigate these issues or avoid them altogether.

The Internet of Things involves objects and entities collectively known as Things. These Things have unique identifiers and the ability to automatically transfer data over a network. As access to Things is over the Internet, security is crucial.

Consider the question check list if your question fits the tag. You can also look at the example questions. If this tag doesn't fit your question have a look below at somehow related tags that might fit your question better.

Question checklist

  • Is the question about the security of IoT devices, setups or networks?
  • Is the question NOT about safety? (if it burns, it's about safety; if it's hacked, then it's security.)
  • Does the question describe clearly what security issue is the concern or is to be avoided?

Example questions

Not what you are looking for?

  • Use for questions about setting up and configuring networks for your IoT devices in general.
  • Use for questions about the operational safety of devices.
  • Consider asking on Information Security Stack Exchange if your question has no IoT connection whatsoever.
