The increasing of innovated technology every day, is making the world more connected as device are getting gradually more digitalised, with every device linked to the Internet, and generating an enormous amount of data all over the Cloud.

The main characteristic of such smart devices is to pull together data and send it over the Internet for apps or software to evaluate it. Everyone in the world can track such data, working through an IoT device which tracks the data received from any device.  By the end of the year 2020, there will be 38.5billion devices connected to the Internet!

Several consequences coming from this massive-flow of data:

·       There's a need for a large bandwidth to meet the growth of Internet traffic, better servers for storage, and more rapid networks.

·       There’s a need for inter-connected smart devices, like Windows, iOS and Android ecosystems.

·       A significant challenge is a private network created for inter-acting only among their products, making others unable to get along with these webs.

·       Our current Internet Protocol version 4 (IPv4) can’t manage the increasing number of interconnected devices on the Internet. Therefore, changing to version 6 is imperative.

·       A security vulnerability is a weak spot which can be broken to give in the integrity or accessibility of your IoT device.  Low-level computing, memory, or storage capabilities, reduce opportunities for applying security on devices.

Why is IoT security so important?

IoT security solutions are crucial across industries, commercial, and consumer’s applications, as many factors are involved in encryption, server protection, and several types of protocols that enable any single function, absolutely challenging the collecting, storing, and analysis of data, using various kinds of wireless communication protocols.  This constant communication can also put in danger IoT security and open up ways for malicious players or unintended data leaks.

IoT security lives inside the control, management, and set up of connections between devices to keep data private, restricts access to devices, and to the Cloud resources.

How does IoT device protector work? 

An IoT device protector detects inconsistencies in device behaviour that might be indications of a compromised device.  By following security metrics from the Cloud and comparing them against probable device behaviour, you define the ports opened on the device, whom the device can talk to, where the connection comes from, and the amount of data sent or received.

Check for device traffic and alerts, and if something seems wrong, like traffic from devices to a known malicious IP or unauthorised endpoints; IoT device defender receives alerts, take action, so you can explore deeper and clarify the root-cause.

The use of security building blocks connects devices fast to the Cloud and to other tools which make obligatory security controls such as, authentication, authorisation, audit logging, and end-to-end encryption. Repeated auditing allows you to urge new firmware updates and licenses to guarantee your devices stay ahead of malicious players. No doubt, human or general unintentional-errors and unauthorised players with damaging purposes can set up configurations with destructive security effects.

Solutions to the IoT Security

·       To spot and diminish vulnerabilities, and identify suspicious traffic, you need to inspect device settings regularly, updating version of any app in your mobile or PC.

·       Cyber-attacks attempt against Internet security.  Therefore, Internet Protocol version 6 (IPv6) has to be sharpened to put IoT in place.

·       Secure boot is a system that checks if entry is signed with a cryptographic key authorised by a database in the firmware. Signature verification can come from boot loader or users, to stop any possible execution of unsigned code.

·       Access control supervises access to the system and any section of your data, and limits the right to use only the resources vital to do the job; the intruder has limited access to other parts of the system, reducing any disruption in your security.

·       Device authentication: it works on user’ ID and a password of the device; it validates itself and is authorised to transfer the data. There’s no need for user’s ID.

·       The Intrusion Prevention System (IPS) is a network-security-restraint tech which examines network traffic flood to detect and prevent exposure to manipulations.

·       Every device in your company also needs a firewall or deep-pack of inspection resources to control traffic that ends at the device. The needs of the device could be different from that of the whole network.

·       Attack surface evaluation identify attack vectors related to your specific IoT devices. It lets you spot the use of uncertain network services and protocols with known security weaknesses. If you detect something, you can take the necessary steps to avoid unauthorised-device entry or potential data leaks

·       Threat-impact analysis of publicly or privately disclosed attack campaigns on your IoT devices. You can define detection rules based on known indicators of compromise to identify at-risk devices or devices already affected.

Summing up: IoT devices must be safeguarded to protect users, devices, and companies. An IoT security strategy reduces vulnerabilities via policies like device identity management, encryption, and access control. Take the necessary steps now to detect any intention of potential-unauthorised vector invading your data.
