OT Penetration

Testing Assessment

An Operational Technology (OT) penetration testing assessment is a specialized security exercise that simulates real-world cyberattacks against Industrial Control Systems (ICS). It identifies vulnerabilities in hardware, software and controlling physical processes—like PLCs, HMIs, and SCADA—to prevent operational disruptions, safety hazards, and unauthorized access. It also identifies design flaws in Industrial Control Systems (ICS) Network and System Architecture that could be exploited by attackers to launch successful attacks.

02

Scope

Industrial systems, SCADA networks, and legacy OT infrastructure coverage.

03

Methodology

Uses structured threat modeling and ICS attack frameworks for real-world simulation.

04

Deliverables

Detailed vulnerability reports with actionable remediation roadmap.

05

Purpose

Key Aspects of OT Penetration Testing

01

Focus on Safety and Uptime

Unlike traditional IT Penetration testing, which prioritizes data confidentiality, and is intrusive to network and systems , OT Penetration testing is carefully conducted to ensure zero disruption to production, machinery, and safety systems.

02

Scope

Covers specialized industrial equipment, legacy systems, and network protocols common in manufacturing, energy, and utility and other industrial sectors.

03

Methodology

Follows frameworks like MITRE ATT&CK for ICS ( Add link MITRE ATT&CK for ICS) to map techniques, including reconnaissance, initial access from IT networks, and exploiting control systems.

04

Deliverables

Provides a comprehensive report with risks, technical vulnerabilities, and actionable recommendations to secure the OT environment.

05

Purpose

Validates defenses and strengthens security against threats like ransomware spreading from IT to OT , Insecure Remote Access and various other threat scenarios applicable to ICS environment.
