Secure by Operations: The New Frontier in OT Cybersecurity for Critical Infrastructure

Recent research reveals critical gaps in operational technology security. Organizations face increasing threats to their industrial control systems. A new approach combining IT and OT security is emerging as essential.

Alarming OT Security Breaches in Critical Infrastructure

A new Forrester Consulting study commissioned by Schneider Electric exposes worrying trends. The survey involved 250 OT security decision-makers from global critical infrastructure organizations. Results show 91% experienced at least one OT breach or failure within 18 months. These incidents caused significant operational and financial damage. Service interruptions affected 51% of organizations. Revenue loss impacted 49%, while 53% suffered reputational harm.

The Growing Confidence Gap in OT Protection

Security leaders express serious concerns about their defensive capabilities. Approximately 70% doubt their organization’s ability to protect critical infrastructure. Moreover, 60% question their capacity to detect OT cyberattacks. This confidence gap highlights systemic issues in current security approaches. Many organizations struggle with legacy systems and limited monitoring capabilities.

The IT-OT Security Divide Persists

A fundamental mismatch exists between traditional IT practices and OT requirements. The study reveals that 51% still apply conventional IT security methods to OT environments. However, only 40% maintain 24/7 monitoring for OT cyber threats. This gap leaves critical infrastructure vulnerable to sophisticated attacks. Industrial control systems require specialized security measures beyond standard IT protocols.

Secure by Operations: A Proven Solution

The “Secure by Operations” approach integrates cybersecurity directly into operational environments. This methodology emphasizes continuous, proactive security throughout the technology lifecycle. Key benefits identified in the study include:

• Faster Recovery: Organizations report up to 53% faster recovery from security incidents
• Cost Reduction: Capital expenditure decreases by 51% through optimized security investments
• Enhanced Reputation: 50% of organizations expect improved company reputation and stakeholder trust
• Operational Efficiency: 45% anticipate gains in overall operational performance and reliability
• Compliance Benefits: 44% project better regulatory compliance and audit outcomes

The MSSP Advantage in OT Security

Managed security service providers offer critical expertise for OT environments. Many organizations lack internal resources for comprehensive OT protection. MSSPs provide specialized staffing and continuous monitoring capabilities. They help maintain compliance and manage incident response. This partnership model allows organizations to focus on core operations while ensuring security.

Expert Perspective: Bridging the IT-OT Divide

Jay Abdallah, President of Cybersecurity Solutions at Schneider Electric, emphasizes urgent action. He notes that modern cyber incidents extend beyond technical disruptions. They fundamentally impact trust, operations and financial stability. Organizations must combine internal capabilities with external partnerships. Effective IT-OT integration strengthens security while driving industrial competitiveness.

PLCDCSHUB Analysis: The Industrial Automation Security Imperative

From our perspective at PLCDCSHUB, this study validates emerging industry trends. The convergence of IT and OT security is no longer optional. According to MarketsandMarkets, the industrial cybersecurity market will reach $23.3 billion by 2026. This growth reflects increasing recognition of OT-specific threats. Secure by Operations represents the next evolution beyond Secure by Design. It addresses the reality that security must persist throughout the operational lifecycle. Organizations using PLC and DCS systems particularly benefit from this approach.

Implementation Framework for Secure by Operations

Organizations can take concrete steps to adopt Secure by Operations principles:

• Assess Current State: Evaluate existing OT security controls and identify gaps in 24/7 monitoring
• Develop Integrated Strategy: Create security policies that address both IT and OT requirements
• Leverage Specialized Expertise: Partner with MSSPs for continuous monitoring and incident response
• Implement Continuous Monitoring: Deploy OT-specific security tools for real-time threat detection
• Establish Response Protocols: Develop and test incident response plans for OT environments

For organizations using industrial control systems, understanding these principles is crucial. Explore comprehensive security solutions and implementation guidance through PLCDCSHUB’s industrial automation resources.

Frequently Asked Questions (FAQ)

What distinguishes Secure by Operations from traditional IT security?
Secure by Operations focuses on continuous, operational-centric protection for industrial environments, while traditional IT security often relies on perimeter-based defenses that may not address OT-specific risks.

Why are OT breaches particularly damaging for critical infrastructure?
OT breaches can cause physical disruption to essential services, safety risks, extended downtime, and significant financial and reputational consequences beyond typical IT incidents.

How can organizations start implementing Secure by Operations?
Begin with a comprehensive OT security assessment, identify critical assets, establish 24/7 monitoring capabilities, and consider partnering with specialized MSSPs for expertise and resources.
