What is Industrial IoT?
Process enhancement is made possible by the Industrial Internet of Things (IIoT), which uses machine-to-machine connectivity and
communication with a cloud-based platform. It uses big data analytics,
sophisticated machine learning algorithms, and other technologies to give
manufacturers helpful information.
IIoT is the convergence of operational technology (OT) and
information technology (IT), resulting in a fully integrated ecosphere with
sophisticated networks connecting processes and industrial control systems.
To measure productivity or evaluate health of machines, this
network consists of IIoT devices such as sensors, controllers, industrial
control systems, and other connected devices. As a result, machines can receive
instructions to do autonomous or semi-autonomous operations without the need
for human interaction and at an unimaginably faster speed than humans can
manage when edge computing and actionable insights from analytics are combined. Extreme Defender for IoT offers security solutions that deliver security for endpoints with no embedded security capabilities. Extreme Defender IoT is the original, award-winning product that brings security to points with little or no security.
The Importance of Security for Industrial IoT
Security for IoT in the industry is crucial. The risk of
company data loss is one of the main factors. Given the increased connections
today, losing access to internal systems could significantly impair a company's
capacity to conduct business or even threaten its survival.
The same is true for the medical, aerospace, and defense
sectors, where increased responsibility is necessary due to patents, trade
secrets, and regulated confidentiality. The loss of ownership and use of these
priceless intellectual assets could negatively impact a business or expose it
to substantial liability risks resulting from a confidentiality breach.
Safety is an essential factor in industrial IoT security.
Concerns about public and company safety are present both within and outside of
IIoT. For example, a security lapse that permits unauthorized access to devices
could result in harm or fatalities. Additionally, a violation allowing the
modification of a pharmaceutical formula or an aircraft part performance characteristic
might increase the safety risk for many persons outside the organization.
What are the security considerations and challenges in adopting the IIoT?
The adoption of the IIoT has the potential to reshape how
industries run. Still, it is challenging to improve digital transformation
initiatives while ensuring security in the face of more excellent connectivity.
Businesses and industries dealing with operational
technologies should know about worker safety and product quality. But as OT is
incorporated into the internet, firms are observing the entrance of more
automated and intelligent equipment at work, attracting a flood of new issues that
would necessitate comprehension of the IIoT's inner workings.
Three things need to be prioritized with IIoT
implementations: availability, scalability, and security. Since industrial
operations may already be established or have been in the industry for a while,
availability and scalability may come naturally to them. However, companies may
encounter security challenges when incorporating IIoT into their operations.
One example is numerous firms' continued use of outdated systems and
procedures. The adoption of new technologies is made more challenging by the
fact that many of these have been in use for many years and have yet to be
altered.
Additionally, the growth of smart gadgets has increased
security flaws and raised questions about security accountability. Adopters of
the IIoT are de facto responsible for protecting the installation and use of
their connected devices. Still, device manufacturers are also responsible for
safeguarding their customers when they release new goods. Therefore, manufacturers
should be able to guarantee user security and offer precautions or fixes should
security problems occur.
In this case, Check Point Quantum IoT Protect offers the most comprehensive security options to protect IoT networks and IoT and OT devices. These solutions are for environments such as Enterprise Smart Offices, Smart buildings, Industrial, and Healthcare. Suppose you are developing Internet of Things (IoT) devices or implementing them within your business. In that case, our solutions reduce your vulnerability to IoT cyber-security risks and can prevent the next cyberattack.
As more important security events come to light over time, the need for cybersecurity is further highlighted. For example, when hackers get access to networked systems, the firm is at risk of a significant data breach and having operations suspended. To securely handle physical and digital components, industries and businesses embracing the IIoT must plan and run like technology corporations.
Adopters must also successfully integrate industrial
activities with IT, requiring the security of both connections and data. Users'
data should be handled in compliance with any privacy laws that may be in
force, such as the General Data Protection Regulation of the European Union
(EU) (GDPR). Personal information must be separated from general log data even
though the obtained data is crucial for providing insights into the
infrastructures and devices. An encrypted database should be used to hold
information like personally identifiable information (PII). Businesses risk
exposure if they store unencrypted data in the cloud with other pertinent
activities.
Technology fragmentation has been one of the main issues
with the IoT, and the IIoT is subject to the cohabitation of several standards,
protocols, and architectures. Therefore, IIoT systems' interoperability may
need to be improved by consistently adopting standards and protocols like
Message Queuing Telemetry Transport (MQTT) and Constrained Application Protocol
(CoAP).
As every industrial Internet of things (IoT) device needs a firewall. Barracuda Secure Connector enables cost-effective scaling, no-touch deployment, and comprehensive IoT security for every device. Operational technology and industrial control systems can be safeguarded using Barracuda's trustworthy firewall models, which offer complete protection, connection control systems for industrial use, and the ability to link active networks to IT networks.
What are the risks to IIoT systems?
The absence of fundamental security safeguards is the root
cause of many security issues related to IIoT. Risks develop due to security
flaws such as open ports, weak authentication procedures, and outdated
programs. More potential problems are opened when you combine these with the
network directly connecting to the internet.
Businesses may already be aware of the potential effects on
their operations of IT systems failing due to malware or cybercrime. However,
real-world risks that could affect civilians are a new, important risk issue
brought on by the confluence of IT and OT.
Among other serious repercussions, insecure IIoT systems can cause operational disruption and financial loss. In addition, there are more significant security vulnerabilities in linked environments, including:
- Weaknesses in software that can be used to attack systems.
- Internet-connected devices and systems that can be publicly searched.
- OT systems that have been compromised by the IT environment and used for extortion
- Malicious actions such as data breaches, targeted attacks, and hacking.
- System failure could cause injury to users or bystanders and damage equipment and physical structures.
- System interference could disrupt operations (for instance, by causing product recalls) or obstruct workflow (e.g., production line stoppage).
- The December 2015 cyberattack against a power grid in Ukraine, where the attacker could infect the IT infrastructure to shut down crucial systems and interrupt power to thousands of homes, is a well-known example of an OT system that has been penetrated through the IT environment.
