How to secure IoT devices from cyber security

IoT stands for the internet of things. It refers to a very specific kind of a network which comprises advanced modern technologies, software systems, sensors etc. As days are passing by, the tenacity to use IoT devices in workplaces and in personal sphere seems to be on an upward trail. There is no way to renounce the fact that IoT devices result in augmented business efficiency.  

In spite of all the advancements, IoT devices are not immune to security threats and malicious virus assaults. Therefore, it is more than essential for all of you to make proper and efficient allocation for some supreme security measures to establish peace in your iot architecture.

So, what do you specifically know as IoT devices?

There will be a hell of a list for you to ponder in this regard. As you come to inspect some of the most effective and essential IoT devices, you will find

  • Smart watches
  • Fitness trackers
  • Sensors
  • Smart security systems
  • Virtual home voice controller systems
  • Doorbell cam
  • Smart lock
  • Smoke alarm
  • Air pollution monitor
  • Thermostat temperature control
  • Wifi systems

The security challenges for the IoT devices:

However, before we make a nosedive into the precise and pristine security measures to safeguard IoT devices from cyber security threats, it is important to understand the security challenges in the first place. So, here is a delineation of some of the most vexing issues:

  • Insecure interfaces happen to be a thorny issue in the process.
  • Data Protection measures don’t seem to be adequate.
  • The update functions also appear to be vulnerable.
  • There appears to be significant skill gap related to IoT.
  • Password protection facilities are also feeble.
  • The device management systems are not up to the desired standard.

How to safeguard IoT devices from cyber security

The first thing that you should remember while using IoT devices is that they are internet connected. So, you will need to exert enough precaution and planning before you put them to use. In order to exercise the ultimate range of security solutions for the devices, you will be expected to carry out a few functionalities.

Take care of the router

Secure the router in the first place. Your router needs to be hacker proof. To make sure that you protect the router from the evil clasp of hacker fraternities, you need to keep it in a place where hackers can’t get in so easily. Doing so is important. The reason is when your router is secured, you can rest assured that the IoT devices will be a lot safer.

Network segmentation is a key factor

It is an important part which you should carry out meticulously. It’s a procedure which is integrated with the overall security goals oriented with your IoT devices. With apt network segmentation you can aim at secure granular control to monitor the traffic which your devices are receiving. This tactic on your part would enable you to keep a close tab on every device as well as the respective workloads. Apart from network segmentation, you can also opt for VLAN or virtual local area network configuration.

Adopt strong password protection practices

You need to be as cautious as you can with regards to the password protection part. If you have multiple devices then it’s reasonable for you to specify a separate password for every device that you own. With a strong password you can literally sidestep a hell lot of issues for sure.

Be wary of cloud services

How cloud services could be a threat to the IoT devices? One of the major reasons is that you will be able to access the data from the locally connected segments of the devices. Veterans deem it to be unsafe, impractical as well as unencrypted. Owing to the cloud infrastructure, IoT architecture could be vulnerable to DDOS assaults.


If you are using UPnP or universal plug and play, then there are reasons for you to take added precautions. Unprotected UPnP could make you land in trouble. Therefore, it is highly recommended that you should make sure to turn this facility off. It’s better if you are using any latest version of firmware. It will protect your devices.

Inspect the connected devices

You will find it fruitful if you check out and analyze the visibility of the devices connected with the network. You have to be thorough with this inventory. Take care of the every single detail that you come across. For example, you should observe and record the firmware details, serial number, software versions, model ID and manufacturer details. It will help you figure out how much risk those devices could be exposed to.


The aforementioned tips and tricks are some of the most surefire and instrumental workarounds which you can employ to steer clear of the cyber threat issue related to the IoT devices that you call your own. Besides, you can add next generation firewall strategies to streamline an across-the-board security solution for your IT assets and devices. When everything is said and done, don’t forget to update the firmware versions you are using. Stay informed and stay protected from the cyber barrages.
