How To Secure Internet of Things (IoT) And Challenges

Some Internet of Things (IoT) secure points you need to know

  • Always create a separate network.
  • Don't connect your device to internet unless you need
  • keep different passwords for each device.
  • Make sure your Firmware fully updated.
  • Don't Keep your personal IoT devices to work.

1. Secure by Default

  • No default passwords shared between devices, or weak out of the box passwords.
  • All passwords should be randomly created using high quality random number generators.
  • Advanced features utilized by a small percentage of users should be turned off (VPN, Remote Administration, etc.)

2. Secure by Design

  • Firmware should be locked down, so serial access is not available.
  • Secure Element (SE) or Trusted Protection Modules (TPM) devices should be used to protect access to the firmware and hardware.
All GPIO, UART, and JTAG interfaces on the hardware should be disabled for production versions.
NAND or other memory/storage mediums should be protected with epoxy, ball sockets (so the memory cannot be removed and dumped), or other methods to prevent physical attacks.

3. Self-contained security

The devices should not rely on the network to provide security. Rather, the device's security model should assume the network is compromised and still maintain protection methods. This can be done with prompts to the users to accept handshakes between devices trying to access other devices on their networks. Communication between devices should be encrypted to prevent MitM attacks and sniffing/snooping.

1. Sensing a complex environment
Innovative ways to sense and deliver information from the physical world to the cloud.

2. Connectivity
Variety of wired and wireless connectivity standards are required to enable different application needs

3. Power is critical
Many IoT applications need to run for years over batteries and reduce the overall energy consumption

4. Security 
Protecting users' privacy and manufacturers' IP; detecting and blocking malicious activity.

5. IoT Application
IoT application development needs to be easy for all developers, not just to experts.

6. Complex
 IoT solutions encapsulate wireless and Internet communication and make hardware and software design simple.

7. Cloud Service
IoT applications require end-to-end solutions including cloud services.


  1. I agree that if you plan to stay with a cheater don't try to find any information. However, in my case I needed it in my state in order to file for a divorce and come out of the relationship. You can't just say I think courts want proof or you end up spending a lot of time and money to fight it out! Finding out was hard, but I was relieved that I wasn't crazy and it's making my divorce go a lot smoother. He would never confess; therefore, I did the best thing for me...find out, no doubt, move on!!!contact [email protected].he's a professional and will surely help you out,tell him from Jes
