Internet of Things is becoming popular and leading the technology trends today. In IoT, multiple smart devices are connected to a network for communication and carry out labour-intensive data exchange tasks. When the IoT applications are introduced into various industries, the need of human intervention is minimal and so convenience and speed is achieved.
As every coin has two sides, with infinite possibilities of using IoT technology also comes tons of potential risks. With a data point of view, privacy and security both are major concerns when IoT is to be implemented, as more than one device are connected in the same network. Thus, protection from any kind of cybercrime is important.
Have a look at a few strategies to fuel your IoT devices with security:
Data Encryption should be secure and robust
When the present data security and data encryption methods are used for protection of the IoT devices, they fall poor and inefficient owing to the volume of data. The general protocols that are used are the web protocols that communicate on the web through some plain text. Thus, a plain text can be the best and easiest way for hackers to target the system by identifying the weaknesses while supervising the traffic on the network.
Set up VLAN & build contact policies for the network that is highly restrictive
When contact policies are made highly restrictive, only then they can ensure that all the connected devices have safety and invulnerability to any kind of attacks. There should be some novelty in the authentication and inbuilt rules for firewalls as well. There should be restrictions for the use of IoT devices over normal TCP/IP ports to ensure security.
Protect & centralize access logs of IoT
When multiple devices are connected in any network and if they lack IT knowledge, then they are vulnerable to security threats. IT admin has all the data about connected devices, but it takes a lot of time to scale and secure the enormous amount of data of the connected IoT devices. Thus, assault by any hacker is expected, keeping the vulnerability of the network in mind.
Password policies must be made effective and transparent
Without any reliable and secure password protection or authentication that is strong or multi-factor, all the IoT devices are at risk of any kind of assault. It is kind of rare to have strong or strict password policies for the IoT devices that are equipped in the houses, printers, or elsewhere. But, it is a must to ensure security.
Design computer architecture for security and protection of all the data
There are heavy chances of IoT devices catching malware or any other kind of virus in the manufacturing or supply chain itself owing to the lack of security measures taken to protect the devices. There have to be robust security and protection mechanisms implemented in the supply chain itself to ensure the security of data.
