Most of the companies in the industrial sector have a basic level understanding of industrial internet of things. The concept of IIOT is emergent of machine-to-machine, predictive analysis and manufacturing techniques and ideologies to improve the functioning of the industrialized sector.
However, application of industrial internet of things in industrial organizations can be a huge menace, especially when devices are interconnected to control the heavy machinery and hazardous systems. Security of IIOT systems is the major concern of emerging industry trends.
Here are some ways to improve the security of IIOTs.
- 1. Understand the Concerns:
Initially, manufacturers of the industrial internet of things do not provide a high level of security. Therefore, factors like asset ownership, standardization, network issues and resource allocation should be kept in mind while deciding upon the security of the entire IIOT.
- 2. Study and Analyze Attack Trends:
As every operation is internet based, it is more likely to be attacked by various ransomware and malware. Attackers are constantly trying out to exploit the vulnerabilities of old devices and target the complete IIOT systems and devices. The trend of these attacks should be continuously studied and analyzed.
- 3. Evaluation of Risk:
IT and OT need to be blend together for an efficient performance of IIOT. IT deals with infrastructure, security, and governance of an organization, whereas OT is concerned with quality and efficiency of the systems.
Hence, the levels of security differ for both IT and OT. Both shall be assessed differently and risks should be evaluated thereon.
- 4. Considering the Major Security Viewpoints:
Various viewpoints and constraints should be looked at while addressing the security issues of the IIOT. End to end security patterns should be handled from hedge to cloud and legacy systems shall be used to guard all the security technologies.
Therefore, a right mix of human and automation interaction should be accounted for while defining the IT constraint systems.
- 5. Risk Classification:
As risk is dynamic in nature, the organizations should consider the legal ownership and supporting systems of the IT environment. An accurate and comprehensive security posture is required to assess and classify the IT risks that are helpful in framing a security framework for addressing these risks.
- 6. Consider the Devices:
When considering the industrial internet of things systems, features like on-boarding, authentication and provisioning should be thought on. Moreover, data is sent using various devices so data integration, confidentiality should be the primary focus. Data, asset management, business analytics and visibility should also be focused on.
- 7. Considering the Gateways:
Apart from device consideration, gateways are another critical factor for securing the IIOT. Starting from the very beginning, secured boot and execution process and credential data storage are best to secure the data gateways.
- 8. Value the Fog Leverages:
Adding fog features serves for various benefits such as real-time decision making, reduced costs of data transferring and improvised data security and continuity.
- 9. Secured Data Access:
For better data security and access, industrial standards should also be used. The focus should be laid on secure management of systems keys, credentials and access tokens.
