IoT devises security

The act of protecting Internet of Things devices and the networks to which they are attached is known as IoT protection. Industrial robots, smart energy grids, building automation, and personal IoT devices workers carry to work are examples of IoT devices in the workplace.

The protection of IoT devices was not considered when they were built. In the vast majority of instances, encryption cannot be installed on the computer itself. Furthermore, they may contain malware, which infects the network to which they are attached.

Some network protection systems cannot detect connected IoT devices and/or insight into what devices communicate over the network.

What is IoT?

The Internet of Things (IoT) is a network of interconnected devices, each with its unique identifier, that collects and exchange data automatically over a network.

  • Smartphones, smartwatches, and smart homes are examples of IoT consumer devices that can regulate anything from air conditioning to door locks from a single unit.
  • Business applications – Companies use various IoT products, such as smart security cameras, truck, ship, cargo trackers, and sensors that collect data about industrial machinery.

How can one handle the vulnerabilities?

C&C centres and APIs efficiently manage day-to-day IoT activities. However, because of their centralised existence, they have a range of exploitable flaws, including:

  • Unpatched vulnerabilities – Computers operating on obsolete software are vulnerable to newly discovered security vulnerabilities due to connectivity problems or the need for end-users to manually download updates directly from a C&C centre.
  • Weak authentication – Manufacturers often release IoT devices (e.g., home routers) with easily decipherable passwords, which vendors and end-users can leave in place. These devices become easy targets for attackers running automated scripts for bulk exploitation when they are left open to remote access.

APIs are typically targeted by a number of threats, like Man in the Middle (MITM), code injections (e.g., SQLI), and distributed denial of service (DDoS) attacks, as they serve as a portal to a C&C core. Here's where you can learn more about the ramifications of API-targeting attacks.

Our methodology to address the problem

An integrated solution, such as a comprehensive security fabric approach, can provide IoT security by providing visibility, segmentation, and safety across the entire network infrastructure.

Your solution should be capable of performing the following tasks:

  • Learn how security solutions can authenticate and identify IoT devices to build a risk profile and group them into IoT device groups with full network visibility.
  • IoT devices can be segmented into policy-driven categories based on their risk profiles until the business recognises the IoT attack surface.
  • Protect: Internal network segmentation and policy-driven IoT groups allow monitoring, inspection, and policy enforcement based on activity at various points within the infrastructure.

What are the threats that these devices can face?

Let us have a look at how the IoT devices can suffer issues:

Theft of data

A vast amount of data is stored on an IoT computer, all of it exclusive to its individual users, such as internet browsing/purchase history, credit card information, and personal health information.

This data is vulnerable to theft if the computer is not properly protected. Furthermore, insecure machines may be used as gateways to other parts of the network, allowing for the extraction of more sensitive data.

How can IoT devices security help you?

IoT devices are being deployed into networks at an incredible pace, with up to 1 million devices being added every day. Although the Internet of Things (IoT) solutions enable new and exciting ways to improve performance, flexibility, and productivity, they also introduce a new network danger. IoT devices, which are often built without encryption, have become a new threat vector for bad actors to use in their attacks. We've already seen several attacks that take advantage of these widely dispersed, seemingly harmless devices.

In the age of the Internet of Things, network operators must have the tools and skills to:

To understand what IoT devices are being deployed, look at and profile every device on the network.
Control network access, including both connecting to the network and deciding which devices have access to it.
Monitor network devices to ensure that they are not infected and take automatic and prompt action.

Why choose us?

The sheer number of Internet of Things devices makes protection a top priority, and it's critical for the internet ecosystem's long-term health.

For system users, this means following common security best practices like changing default security passwords and blocking unwanted remote access (for example, when it's not needed for the device's functionality).

On the other hand, vendors and software manufacturers should take a wider approach and invest heavily in securing IoT management resources. The following are some of the steps that should be taken:

Notifying users when their computers are running obsolete applications or operating systems.
Password management that is smart (e.g., mandatory default password changes).
Disabling remote access to a computer unless it's necessary.
APIs would be subject to a strict access management policy.
Defending C&C centres against hacking attempts and DDoS attacks.

DigiAlert cloud WAF protects IoT manufacturers' C&C centres by offering on-edge traffic filtering services that ensure that only approved and authenticated client requests access their APIs.
