Is IoT is Actively Shaping Security Needs at Edge?

September 30, 2019

Today most of the technology is spinning the best version of the industry. Many of the always-connected devices are drawing the full advantage of cloud computing, meanwhile, IoT manufacturers and app developers are discovering to scratch the benefits of performing more computational analytics on the devices themselves.

This approach skips latency for critical applications, decreases dependency on the cloud, and assures better management of deluge of data generated by the IoT.

The number of devices connected to the Internet to make up the IoT, i.e., machines, sensors, and cameras is in use without any obstacle.

IDC has forecast to have 41.6 billion connected IoT devices or things till 2025, generating 79.4 zettabytes of data. As this data would expectedly boom in the near future, the data generated will also increase. It would turn more challenging for enterprises to protect the Edge-the source of the data.

The influence of IoT is shadowing the whole globe with the fastest of its speed. The entrepreneurs are targeting to put more intelligence on the Edge using smarter and potential devices. This new advancement expands the old-traditional enterprise IT infrastructure beyond a data center or cloud environment.

Starting its way from small things till trucks, containers, kiosks, warehouses, and commercial buildings, everything is creating an ecosystem of Edge devices that does not restrain till data collection and disseminates data but performs highly complex tasks like Artificial Intelligence (AI) at the outer reaches of the network.

The shared data reflect the high risk of the data breach as no. of edge devices are increasing.

As per last years stat. 1244 data breaches which exposed 446.5 million records which comes at a high price.

Ponemon Institute calculates that the data breach cost (average) would exceed to $3.5 million, and definitely this loss magnitude is not entertaining for businesses.

So it’s a crucial time for entrepreneurs to take an appropriate step to paralyze loss-making ongoing breach and protect themselves from its vulnerability.

Edge the new future

Edge computing and IoT: A way to balance act?

The primary purpose of Edge computing is to overcome the enormous data generated by IoT sensors and devices.

For many applications, this system means to analyze and act on data at the Edge of the network (closer to data sources) than forwarding it to the remote or centralized data center for processing.

Most of the time, an IoT device processes it.

Introduction of data-generating devices to the network in increasingly remote location causes cybersecurity vulnerabilities, gifting them an easy entry point into the network that can be used to get into the core systems that the Edge devices connect to.

To sum up, today, entrepreneurs need to secure each device instead of focusing on perimeter protection. In short, the concept of the network perimeter is vanishing. Instead of defending the perimeter, the enterprise must secure each device.

Public Key Infrastructure as a proactive solution

Clutching the data breach that can exploit the IoT network need thorough data protection and device security solution. A single mistake in the security of any device on the network imperils the entire network.

Edge node security can be referred to as supreme to prevent exploitation of any access point, including proactive rather than reactive cyber-defense.

Attack vectors are unpredictable or inconsistent, so IoT protection must be updated with time.

Baseline defense mechanisms include authentication and verification of devices in the network.

It has been concluded that static credentials with a strong password have lost the potential to provide a high level of protection to escape from operational disruption or data loss.

Old-tradition-bound security applications like antivirus and firewalls do not work with the devices that are out beyond the enterprise’s network.

Cohesive encryption algorithms and certification based authentication are must be required. PKI (Public Key Infrastructure) framework can provide encryption to protect data in motion across the networks and assures that all the connected devices are authenticated.

Edge computing and IoT are new architectures that need the latest high-level security approaches. No old concept is adaptable today as it offers no security or if applied the processors set up at the Edge must have an encrypted shield against attack. Robust identity verification and encrypted data transmission are two essential components of this approach.
