IT/OT convergence needs a human-centered approach

Sept. 3, 2024
This path sees technology as only part of the solution, putting flesh-and-blood users such as IT pros, OT operators, and third-party vendors at the heart of integration.

In today's tech landscape, IT and OT are converging. This is a focus for organizations seeking more efficiency and better security. Convergence combines IT’s data management with OT's operations. It offers new opportunities for optimization and innovation. However, the success of IT/OT convergence hinges on one principle: a human-centered approach.

A human-centered approach to IT/OT convergence sees tech as only part of the solution. At the heart of this integration are the daily users: IT pros, OT operators, and third-party vendors. Each group has unique needs and priorities. These must be addressed to ensure successful convergence.

For OT professionals, the primary focus is operational stability. They rely on systems that are reliable and consistent. They must perform under the pressures of a production environment. IT professionals focus on cybersecurity. They aim to protect integrated systems from threats. To balance these priorities, one must know each team's needs.

Building bridges between IT and OT

IT and OT teams must unite to share expertise and responsibilities. This work must start with a shared understanding of each team's goals and challenges. IT teams must understand that OT operations are critical. They must minimize disruptions. OT teams should know the cybersecurity threats to their systems and how serious the peril is. They must also follow IT security policies.

One effective strategy is to form cross-functional teams. They should include members from both IT and OT departments. These teams can work together. They can create strategies that address both operational and security concerns. By fostering open communication and respect, these teams can find solutions. They will improve both efficiency and security.

Often, third-party vendors play a significant role in the IT/OT ecosystem. These vendors may offer vital tools, services, or support. They are essential for maintaining and optimizing IT/OT systems. It's a delicate balance. We must give vendors access while keeping security.

Effective involvement of third-party vendors

Organizations involve third-party vendors while maintaining secure access through best practices.

  1. Define access levels: Specify the access levels vendors need. Restrict access to only the necessary systems and data. Put in place role-based access controls (RBAC) to enforce these restrictions.
  2. Secure communication channels: Use encrypted communication channels and secure protocols for interactions between vendors and internal systems. This helps prevent unauthorized access and data breaches.
  3. Vendor management policies: Establish comprehensive vendor management policies that include security requirements, performance metrics, and regular reviews. Ensure that vendors are aware of and adhere to these policies.
  4. Regular audits and assessments: Conduct periodic audits and security assessments to check vendor compliance and identify potential vulnerabilities. This proactive approach allows organizations to address issues before they become significant threats.

Compliance is another critical aspect of IT/OT convergence. Organizations must navigate a complex landscape of industry-specific regulations and cybersecurity standards to ensure that their systems meet all required criteria. System integrators are vital. They provide expertise to help organizations achieve and maintain compliance.

Industry-specific regulations and cybersecurity standards

Some specific industry regulations and cybersecurity standards that organizations need to navigate:

  • ICS cybersecurity: Standards like NIST SP 800-82 and ISA/IEC 62443 guide securing industrial control systems.
  • Financial sector: The PCI DSS and FFIEC guidelines protect financial data and systems.
  • Health care: HIPAA mandates the protection of healthcare data. HITECH emphasizes the secure use of electronic health records.
  • Energy sector: The NERC CIP standards address grid cybersecurity. They apply to the electric grid and related infrastructure.

One size does not fit all when it comes to compliance. Each organization has unique needs and challenges.

So, compliance strategies must be tailored accordingly. System integrators can help organizations create IT/OT convergence strategies. These must meet specific compliance requirements. Examples of tailored compliance strategies include:

  1. Custom security policies: Create and enforce security policies. They must meet industry regulations and address your organization's unique risks.
  2. Risk assessment and management: Identify vulnerabilities through detailed risk assessments. Then, put in place strategies to manage risks from specific threats.
  3. Ongoing training and awareness programs: Train employees on compliance and security best practices.
  4. Incident response planning: Create and update incident response plans. They must fit your organization and industry standards. This ensures a swift and effective response to any security breaches or compliance issues.

A tailored approach helps organizations. It ensures secure, efficient operations and compliance with industry standards. It protects sensitive information and builds trust with stakeholders and regulators.

The merging of IT and OT offers organizations many opportunities. They can improve their operations and security. However, a successful integration needs more than tech solutions. It requires a human-centered approach that addresses all stakeholders' needs and concerns.

Organizations can create strong, resilient environments by fostering collaboration between IT and OT teams, involving third-party vendors appropriately, and ensuring compliance through tailored strategies. These environments will support both operational stability and cybersecurity.

As IT/OT convergence evolves, we must focus on human-centered methods. They will help us navigate the complexities and achieve lasting success.
