Technical capability / 02

OT/ICS, FRCS & Cyber-Physical Security Engineering

L-TTEC. applies systems engineering and technical assurance to operational technology, industrial control systems, facility-related control systems, and other cyber-physical systems.

How the work is structured

A defined path from technical problem to evidence.

OT and cyber-physical decisions cross physical, digital, safety, security, mission, and organizational boundaries. IT/OT interfaces must be understood without assuming authority to access or change an operational system.

  1. 01

    Bound the system and authority

    Identify assets, operators, interfaces, dependencies, governing constraints, and the actions that remain outside the assessment.

  2. 02

    Trace hazards and security requirements

    Relate architecture and IT/OT interfaces to credible failure modes, security requirements, operational consequences, and available evidence.

  3. 03

    Prioritize assurance evidence

    Sequence verification, validation, test, specialist review, and authorization work for the next bounded decision.

Capability includes

Assess system interfaces, hazards, and security requirements in operational technology and facility systems.

  • OT/ICS and FRCS architecture review
  • Cyber-physical interface and hazard analysis
  • Security requirements and assurance cases
  • Verification planning without unauthorized operational changes

Evidence and handoff

An assurance and verification plan that addresses safety and operational constraints.

  • A bounded architecture and cyber-physical interface model
  • A traceable hazard, security, dependency, and assurance register
  • Prioritized verification and test activities that preserve operational authority

Capability fit

Start with the decision you need to make.

Best for
  • Facility, industrial, infrastructure, defense, or mission teams defining one cyber-physical system decision
  • Programs preparing an OT/ICS or FRCS integration, modernization, security, verification, or test activity
  • Prime teams that need a bounded systems-engineering or assurance work package
Typical technical questions
  • What assets, interfaces, operators, and authorities belong inside the system boundary?
  • Which safety, security, and operational failures need explicit treatment?
  • What evidence is required before an integration or change can advance?
Boundaries
  • No unauthorized access, penetration testing, or modification of an operational system
  • No claim of certification, compliance, accreditation, safety approval, or authority to operate
  • This is not general help-desk, device-management, or managed IT service delivery

Bounded technical work

Bring the decision, available evidence, and constraints.
