How can enterprises mitigate the security risks of Internet of things and industrial Internet of things

COVID-19 The digital industrial revolution after the pandemic triggered the Internet of things (IoT) And the industrial Internet of things (IIoT) Strong growth in the market . However , These game changing technologies have security risks that must be addressed , Only in this way can the enterprise get all the benefits . As enterprises increasingly rely on the Internet of things and industrial Internet of things to manage key business systems , Finding the right safety method is crucial .

Internet of things and industrial Internet of things have inherent risks , Because they are usually deployed faster than protection . This makes enterprises face the danger of network threats , For example, device hijacking 、 Data leakage or siphon 、 Equipment theft 、 Spoofing and denial of service attacks . These types of attacks will bring serious operational problems to enterprises 、 financial 、 Safety and reputation consequences .

This is particularly worrying , Because enterprises trust technology to collect sensitive data 、 Connect virtual and physical environments 、 Manage production workflow and predictive maintenance （ Including the safety aspect ） And mutual dynamic interaction . When trust technology reaches this level , It is crucial to ensure that enterprises formulate correct policies to reduce risks and reduce the impact of network leaks .

A key problem is that the design of IOT and industrial IOT devices is not safe , Many devices have hard coded passwords in their firmware , Therefore, it is difficult to patch or update security . Even if security is installed on the device , In most cases, it can also be circumvented by exploiting a wide range of known vulnerabilities . When IoT or IIoT When the equipment is threatened ,IT The team may find it challenging to detect an event before it affects the system and data .

There are five ways to alleviate IoT and IIoT Safety risk . As part of this approach , It is important to consider the whole IoT/IIoT Environmental Science , Instead of treating it as a separate component or device .

1. Segment the production environment , So that all IIoT And wireless devices are located in monitoring and data acquisition (SCADA) Or industrial control system (ICS) Outside the network . in many instances , Differential segments are required to allow only authorized communication between devices .

2. Control network access by continuously monitoring devices connected to the network and verifying the security status of each device before connecting .

3. Need seamless visibility across all networks and devices used for security monitoring and management across the enterprise . This should be centralized , So that it can be used in production and IT View and manage all devices in real time in the environment 、 The Internet 、 risk 、 Traffic and strategy .

4. Use intrusion protection system (IPS) To help detect attacks and provide IoT and IIoT Virtual patching of devices . meanwhile , Deploy active protection scheme and deception technology , Deal with unknown threats .

5. Use automatic secure remote access with zero trust , In this way, everyone on the network can be verified , And no matter where the authorized user is , Applications remain secure .

When adopting security solutions , It is important to ensure that they can automatically expand according to business needs . This includes adapting to network changes 、 Predict and actively manage threats and provide real-time Threat Intelligence .

The new generation of security tools achieve this goal by providing better visibility into the network environment while automatically responding to damaged devices or suspicious activities .

These tools directly meet operational and regulatory needs by providing centralized management and unified context aware security policies , This provides fine-grained control and visibility across all devices and Networks .

In this way , Current and emerging IoT and IIoT Security solutions can ensure the integrity and protection of assets in automated organizations , Protect them from emerging cyber threats .
