IoT & Industrial / Operational Security

IoT & Industrial / Operational Technology (OT) Security

As organizations increasingly rely on IoT devices, industrial control systems (ICS), and operational technology (OT), the attack surface expands into critical operations. From smart building systems to SCADA networks and manufacturing controllers, weaknesses in these systems can lead to operational disruption, safety hazards, and significant financial loss. Obventum’s IoT & Industrial/OT Security Assessments are designed to uncover and mitigate these risks with highly targeted, manual testing performed by experienced offensive security professionals.

Scope of IoT & OT Security Assessments

• Industrial Control Systems (ICS) Testing – Assess SCADA, PLCs, and ICS networks for exploitable vulnerabilities in control logic, protocols, and authentication systems.
• Operational Technology (OT) Security – Evaluate process control networks, factory automation systems, and critical infrastructure components for misconfigurations, access weaknesses, and potential attack vectors.
• IoT Device Security – Test embedded firmware, wireless protocols (Zigbee, LoRaWAN, BLE), cloud connectivity, and local device interfaces to identify risks that could impact enterprise or industrial operations.
• Network & Protocol Analysis – Examine traffic between devices, controllers, and cloud services, identifying insecure communication, unencrypted protocols, or weak access controls.
• Physical Security Assessment – Review potential physical attack vectors on industrial devices or OT components that could compromise operational integrity.

Types of Testing

• Blackbox Testing – Simulates an external attacker targeting your systems without prior knowledge.
• Greybox Testing – Uses partial access to focus on critical devices or components.
• Whitebox Testing – Full system knowledge allows in-depth analysis of firmware, configurations, and industrial protocols.

Manual, Expert-Led Testing
Automated scans are insufficient for complex OT and IoT ecosystems. Obventum’s team conducts fully manual assessments, combining technical skill with industry expertise to detect subtle flaws, insecure configurations, and chained vulnerabilities that automated tools often miss.

Methodologies & Frameworks
Obventum applies recognized industry frameworks and best practices to ensure effective and actionable assessments:

• OWASP IoT Top 10 – For IoT-specific vulnerabilities.
• NIST Cybersecurity for IoT & ICS – Ensures alignment with regulatory and operational standards.
• PTES & OSSTMM Principles – Structured, repeatable offensive security approach.
• ISA/IEC 62443 Standards – Operational technology security guidelines for industrial environments.

Deliverables & Reporting
Clients receive detailed, actionable reporting including:

• Executive summary highlighting critical risks to operations and safety.
• Technical findings with proof-of-concept exploits.
• Prioritized remediation plan to reduce exposure and strengthen defenses.
• Guidance on improving security culture across human, technical, and operational layers.

Value of IoT & OT Security Testing with Obventum

• Protect industrial operations and critical systems from targeted attacks.
• Reduce risk of operational downtime, financial loss, or safety incidents.
• Strengthen connected devices, network protocols, and control systems.
