Internet of Things (IoT) Security Challenges & How to Overcome Those?

One of the biggest potential advantages of 5G networks is the ability for machines to communicate with each other directly. This has enormous potential for IoT applications, which help devices work more efficiently by allowing them to exchange data with each other. 

However, this possibility comes with a significant security challenge: the ability for machines to send data to machines without going through a human operator first. 

Internet of Things (IoT) Security

Fortunately, there are several strategies for IoT security that  network operators can use to address the challenges:

1. Trust management

Network operators will have to establish clear, fair, and enforceable trust-management policies.

2. Operational Controls

Operators will have to put in place operational controls to ensure devices are operated only by trusted personnel.

3. Security Controls

Finally, operators will need to implement security controls, such as authentication, to ensure that devices send only authorized data.

How to Overcome IoT Security Challenges

Once network operators have implemented above mentioned IoT security strategies, they will be faced with a new set of challenges. Below are the list of challenges will be faced in IoT security implementation:

1. Standardization

Network operators will have to figure out how to standardize the management of trust between devices.

2. Authentication

Network operators will have to find a way to authenticate devices, preventing would-be attackers from disguising themselves as legitimate devices.

3. Data access

Finally, network operators will have to find a way to regulate data access so that attackers don’t access sensitive data out of the ordinary.


The deployment of 5G networks in IoT will bring with it a host of new security challenges. While these networks will be incredibly fast and powerful, they will also be decentralized and highly flexible. 

In order to address these challenges, network operators will need to implement a range of strategies, including standardizing the management of trust between machines, authenticating devices, and regulating data access.
