6 Steps to Map out IoT Gateway Security

In the IoT ecosystem, IoT gateway security having great importance since it is an essential part of data collection. If there are not enough security measures, there is a possibility of potential risks such as a harmful threat, spoofing, man-in-the-middle (MITM) attacks, etc. If you misplace a gateway at the center of the communication chain, it will put the entire IoT ecosystem at risk. The global IoT node and gateway market size are expected to develop from USD 387.1 billion in 2020 to USD 563.7 billion by 2026; at a CAGR of 6.5%.

IoT Gateway

An IoT gateway is a device that bridges the communication gap between IoT devices, sensors, systems and the cloud. By orderly connecting the field and the cloud, IoT gateway devices provide local processing and storage solutions and the capability to autonomously control field devices depends on data input by sensors.

Industries utilize IoT gateways for several purposes, likewise building automation and fleet management, in industries containing industrial asset management as well as maintenance. They sustain connectivity and security of IoT devices on any network across a broad range of physical locations.

Cybersecurity as a Key Function of Gateways

Communications between the things, the gateway as well as the cloud hence must be secure in order to protect any data interfering or unrestricted access.

Unidirectional gateways prevent legacy devices that cannot be saved remotely by only enabling data to proceed in one direction, generally from the device to the gateway. Gateway filtering technology can analyze, control and secure the information transfer via authenticated traffic with packet filtering or physical network signal filtering. Even In the case of IoT devices are hacked, the gateway can obstruct the data from the remaining network. Again, if attackers hack the gateway, it can check access to the devices and the network via authentication protocols.

6 Ways to Secure IoT Gateways

Below are six ways that will assure IoT gateways should remain as secure as the whole network and devices.

Apply only Authenticated IoT Gateways

You require the gateway to assist the onboarding of devices (installation of certificates and furnishing of identity). Most of the gateway vendors provide security certificates with their devices and software that confirms the products’ security level. Just install secure gateways that combine with security protocols already in use. Assure it unites with already installed IoT devices and does not generate vulnerabilities within the network.

Execute a Security Assessment Before Implementation

It is important to execute a security assessment to assure it fulfills the industry’s security requirements as well as legal requirements, even after the admin acquires a gateway. Every gateway has various characteristics that may affect where to place it, how it’s utilized within a network and how it adjusts into a security stack.

Upgrade Gateway Software

A software security report observes that 85% of organizations had outdated or exposed to software in their networks. Outdated software is generally a security risk, so it’s significant to retain IoT gateways updated.

Systematically Review Access to the Gateway

IoT admins can simply install a device and not modify any of the default settings or access accounts, but doing this could create serious issues. To eliminate the IoT gateway risk, analyze and update the access list usually, involving user accounts as well as IoT devices. Repeal permissions from anyone or any device that no longer requires access or seems queer.

Involve Gateways in Security Audits

With the outbreak of IoT devices in most networks, it can be challenging to maintain track of them all. You need to assure to involve IoT gateways inefficient assessments and audits. Design a plan of doing a separate IoT security audit as the technology modifies quickly. Maintain decision-makers and data center admins updated on the recent reports and threat intelligence so they can dynamically address issues.

Utilize a Different Network for IoT Gateways and Devices

Vigorous security should be given to the communicating channel and encryption for the transference of the IoT payload. Industries frequently utilize IT networks for IoT device communications, which improves the security risk. Datacenter admins should also analyze network traffic usually, particularly at the communication integration points between regular and IoT networks. Preferably, utilize a different network for IoT devices and gateways to divide traffic and separate IoT devices from attack.
