A Smarter Approach to Securing Industrial Environments

Modernizing Asset Inventory

OT/IoT asset management is being elevated to a new level of importance

Digital Transformation: Opportunities and Risks

• Static communications in air-gapped network

• Known and controlled assets

• Minimal external communication

• Mix of legacy and smart assets

• Increased asset count and communication flows

• OT-IT integration and cloud/remote access

The Past The Present

Key Value of OT/IoT Asset Management

Visibility

Know what assets you have, where they are, and how they're used—eliminating blind spots

Cost Control

Optimize asset utilization and avoid unnecessary purchases and plan maintenance to reduce downtime

Lifecycle Management

Track assets from onboarding to retirement for smarter budgeting and upgrades

Key stakeholders

Chief Information Security Officer Operations/Plant ManagerChief Information Officer

Security Compliance

Streamline compliance with security regulations through audit-ready reporting and accurate asset data

Faster Incident Response

Leverage contextual asset data to detect, prioritize, and resolve incidents quickly

Risk Reduction

Identify and address vulnerable or rogue assets before they impact production

Asset Inventory is a core requirement of many security regulations and standards

The Role of Asset Inventory in Security Compliance

The NIST Cybersecurity Framework (CSF)

NERC Critical Infrastructure Protection (CIP)

Security for industrial automation and control systems (62443)

Asset Management (ID.AM): Assets (e.g., data, hardware, software, systems, facilities, services, people) that enable the organization to achieve business purposes are identified and managed consistent with their relative importance to organizational objectives and the organization’s risk strategy

CIP-002-5: Identify and categorize BES Cyber Systems and their associated BES Cyber Assets for the application of cyber security requirements commensurate with the adverse impact that loss, compromise, or misuse of those BES Cyber Systems could have on the reliable operation of the BES

• 62443-2-1, 4.2.3.4 – Asset Identification and Management: Requires the establishment and maintenance of an inventory of all assets within the IACS, including hardware, software, and data assets.

• 62443-3-3, SR 7.8 – Control Asset Inventory: The control system shall maintain an inventory of all organizationally managed assets.

But OT Asset Inventory Is Different, This Is Why

Information Technologies Operational Technologies

Data confidentiality and integrity is paramount Human safety is paramount

Mostly Non-real time. High delays and rebooting are generally acceptable. Real time. High delays and rebooting are unacceptable.

Enough resources for cyber security solutions. Resources are limited for cyber security solutions.

Standard network protocols. Easy to monitor Industry specific protocols, require knowledge to monitor.

Updates are straightforward and automated Updates must be planned, and End-of-Support OSs may be in use

Components are local and easy to access Components may be Isolated, remote, and hard to access

Why traditional methods fall short

Key Challenges in OT/IoT Asset Inventory

Lack of Automation

Asset inventory in OT/IoT environments is often missing altogether or is manual, making it time-consuming, error-prone, and unsustainable at scale

Incompatibility with IT Tools

Traditional IT asset management systems can’t access OT/IoT asset data and lack support for industrial protocols and network architectures

Limited Physical Access

OT/IoT assets are often hard to reach physically, and environments may lack appropriate sensors, making data collection difficult

Risky Collection Methods

Many IT asset data collection techniques are not safe for cyber-physical systems and can disrupt critical physical processes

These challenges highlight the need for a specialized OT/IoT asset inventory approach—one that’s purpose- built for critical physical environments, protocol-aware, non-intrusive, and scalable.
