Question 1

Why Is DNS Tunneling Hard to Detect?

Accepted Answer

DNS traffic looks normal. Most systems don’t block it. Attackers send small data chunks, so alerts don’t trigger. You must track patterns to catch it.

Question 2

What Makes IoT Devices Easy Targets?

Accepted Answer

Many IoT devices run outdated software. Some use default passwords or stay online all the time. That opens the door to silent attacks.

Question 3

How Can You Block DNS Tunneling?

Accepted Answer

Start with DNS monitoring. Block unknown domains. Use strict firewall rules. Limit device access. Remove any IoT system you don’t need.

Question 4

How Do Hackers Use DNS Tunneling in IoT Devices?

Accepted Answer

Attackers hide data inside DNS requests from IoT devices. They use weak passwords or old software to break in. Then they send stolen data out using fake DNS traffic.
