Cybersecurity for Operational Technology: Protecting Saudi Critical Infrastructure

The New Battlefield: When Industrial Systems Become Cyber Targets

As Saudi Arabia accelerates its digital transformation under Vision 2030, a critical vulnerability emerges alongside unprecedented opportunity. The same connectivity that enables smart factories, remote operations, and predictive maintenance also exposes Operational Technology (OT)—the systems controlling industrial processes—to cyber threats that can have physical consequences. Unlike traditional IT security focused on data confidentiality, OT cybersecurity Saudi protects systems where breaches can mean not just data loss but equipment damage, production halts, and even threats to human safety .

The stakes could not be higher. Saudi Arabia produces nearly 10.6 million barrels of crude oil per day, making it the largest petroleum exporter globally . The Kingdom’s energy infrastructure has already witnessed landmark attacks: the 2019 Abqaiq-Khurais drone and missile strike temporarily halted 5.7 million barrels per day of production—about half of Saudi output—while the 2012 Shamoon cyberattack against Saudi Aramco wiped data from 30,000 computers, demonstrating vulnerabilities beyond physical assets . The Saudi National Cybersecurity Authority reported a 55% surge in cyberattacks in 2022 compared to 2021, underscoring the accelerating threat landscape .

For Darkstone Group, this represents a natural extension of our core mission. Having built and maintained the industrial facilities that form Saudi Arabia’s critical infrastructure, we now offer specialized OT cybersecurity services to protect the systems we know intimately—securing the plants and mines we construct and operate.

Understanding the OT Cybersecurity Landscape in Saudi Arabia

What Makes OT Different from IT

Operational Technology encompasses the industrial control systems (ICS) and supervisory control and data acquisition (SCADA) systems that manage physical processes in power plants, water treatment facilities, pipelines, and manufacturing lines. Unlike IT environments, OT systems have unique characteristics that demand specialized security approaches:

• Availability and Safety Priority: In OT, keeping processes running safely takes precedence over data confidentiality. A security measure that disrupts production is unacceptable.

• Legacy Systems: Many industrial control systems were designed decades ago, before connectivity was anticipated, and cannot easily be patched or updated .

• Physical Consequences: Cyber incidents in OT can result in equipment damage, environmental releases, or personnel safety risks .

• Long Lifecycles: Industrial equipment operates for 20-30 years, far longer than IT hardware, requiring sustained security approaches.

The National Regulatory Framework

Saudi Arabia has established a comprehensive regulatory structure for OT cybersecurity, recognizing its critical importance to national security and economic stability.

National Cybersecurity Authority (NCA): As the national reference for cybersecurity affairs, the NCA develops policies, frameworks, and controls that all entities must implement . For OT specifically, the NCA has published the Operational Technology Cybersecurity Controls (OTCC-1:2022), setting minimum cybersecurity requirements for organizations to protect their industrial control systems from cyber threats . These controls align with international standards including IEC 62443, NIST CSF, and ISO/IEC 27001 .

The NCA’s Essential Cybersecurity Controls (ECC-2:2024) framework provides additional guidance structured around four key domains:

• Cybersecurity Governance: Policies, roles, and compliance oversight

• Cybersecurity Defense: Asset security, identity management, network security, and vulnerability management

• Cybersecurity Resilience: Business continuity and incident recovery

• Third-Party & Cloud Security: Vendor risk management and cloud protection

High Commission for Industrial Security (HCIS): Operating under the Ministry of Interior, HCIS develops and enforces security, safety, and fire-protection directives across thirteen strategic sectors including petroleum, electricity, water, mining, gas, petrochemicals, and military industries . HCIS directives are mandatory for critical infrastructure facilities and cover:

• Perimeter security and access control

• CCTV and surveillance systems

• Emergency response planning

• Fire protection systems

• Security design reviews from concept through detailed engineering

Communications, Space and Technology Commission (CST): CST’s 2025 Software Escrow Guideline establishes formal frameworks for Critical National Infrastructure organizations to protect access to critical software assets, ensuring continuity even if vendors fail or withdraw support . This is particularly relevant for OT environments where proprietary control systems are mission-critical.

The Threat Landscape: Why OT Security Matters Now

Attack Surface Expansion

The convergence of IT and OT networks, while enabling operational efficiencies, has dramatically expanded the attack surface. Forescout’s analysis at Black Hat MEA 2025 highlighted that “many organisations are transitioning from legacy, isolated systems to highly connected environments with an increasing number of IoT and smart devices,” introducing vulnerabilities related to outdated platforms, misconfigurations, and devices never intended for network exposure .

Threat Actors and Motivations

Critical infrastructure operators face a wide spectrum of adversaries :

• Nation-state actors seeking geopolitical advantage or strategic disruption

• Ransomware groups targeting industrial operations for financial gain

• Hacktivists pursuing ideological objectives

• Insiders with legitimate access who may act maliciously or inadvertently

Saudi-Specific Vulnerabilities

Kaspersky’s Q2 2024 statistics revealed that while Saudi Arabia emerged as one of the least exposed countries regionally, sectors including Construction, Oil and Gas, and Building Automation showed higher vulnerability. Primary threats include unsecure employee behaviors, such as attempting to access denylisted internet resources from OT computers, exposing systems to malicious scripts and phishing pages .
