ICS/SCADA
Security Assessment

A major international airport required an independent assessment of its OT environment — encompassing ICS/SCADA governing baggage handling, ATC support, energy management, car parking, and building management. Constraint: zero disruption to live operations.

// Module 02: Constraints


THE OBJECTIVE

OT environments run legacy protocols on extended lifecycles. Assessment activity cannot generate traffic that disrupts live control systems. Safety and uptime are non-negotiable.


VEC-01 / Continuity

Zero Disruption Constraint.

Assessment activity cannot affect live system state. Any traffic against control systems carries immediate safety consequences.


VEC-02 / Protocols

Legacy Protocol Surface

Modbus, DNP3, Profinet — protocols not designed with security assumptions. Enumeration must be passive-only throughout.


VEC-03 / Boundary

IT/OT Boundary Gap

Air-gap assumptions unverified. Enterprise segments with lateral pathways into operational control domains.


VEC-04 / Inventory

Undocumented Assets.

Components absent from maintenance records excluded from patch management. Physical survey required for baseline.


VEC-05 / Access

Privileged Access Exposure.

Shared credentials and default accounts on SCADA HMI. Absence of RBAC across operational domains.


VEC-06 / Remote

Vendor Remote Pathways.

Persistent vendor support channels with insufficient session governance and no active monitoring.

// Module 03: Interventions

THE ARCHITECTURE

SYS-01_ACTIVE

  • Physical and logical inspection across all in-scope domains. Verified asset inventory and topology map as assessment baseline.


SYS-02_ACTIVE

  • Non-intrusive identification of exploitable conditions without disrupting live systems.


SYS-03_ACTIVE

  • Controlled tests against isolated components where active testing was permissible. Exploitability validated without risk.


SYS-04_ACTIVE

  • Findings structured by operational impact and exploitability, prioritized for remediation aligned with business continuity.


// Module 04: Ledger

THE OUTCOME

High-risk exposure identified across multiple operational domains. Remediation roadmap delivered. Critical gaps closed without operational downtime. Executive reporting produced in parallel — leadership received risk-informed visibility at infrastructure investment level.
