OT Architecture Assessment

OT Architecture

Assessment

An Operational Technology (OT) Architecture Assessment is a strategic evaluation of an industrial control system’s (ICS) network design, security controls, and data flows against standards like IEC 62443 or NIST SP 800-82. It identifies vulnerabilities, misconfigurations, and segmentation weaknesses to prevent cyberattacks from disrupting physical operations.

Key Aspects of OT Architecture Assessment

Advanced industrial cybersecurity assessments designed to secure critical infrastructure environments.

01

Network Segmentation Analysis

Reviewing VLAN configurations, firewall rules, and Zone/Conduit models to prevent unauthorized lateral movement.

02

Compliance Alignment

Assess the architecture’s alignment with international standards like IEC 62443 or NIST SP 800-82 and Best Practices.

03

IT/OT Boundary Review

Evaluating IDMZ design, unidirectional gateways, and firewalls separating business networks from production environments.

04

Remote Access Evaluation

Assessing VPNs, jump servers, and multi-factor authentication (MFA) used by vendors and employees.

05

Threat Mitigation & Visibility Tools Design

Assessing the architecture design of various OT-specific security & Network monitoring tools, intrusion detection systems, and security logging tools.

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.
