Control system review
Inventory and review of controllers, HMIs, SCADA servers, networks and remote connections.
CAP-03 / Capability
We review the control systems you already run and design new automation so that security is part of the architecture: controllers, HMIs, SCADA, networks and remote access, built to stay reliable and maintainable.
Overview
Most control systems were designed to be reliable, not to resist attack. We start from the process: how the line or the plant runs, which controllers and HMIs it depends on, who connects to it and how. From there we define a control architecture that keeps production running and limits what an intruder could reach.
When you add or upgrade automation, we design it with security from the first drawing: zoned networks, hardened controllers and workstations, controlled vendor access and documentation your maintenance team can use.
Scope of work
Inventory and review of controllers, HMIs, SCADA servers, networks and remote connections.
Zones and conduits, firewalls and data flows defined around the process and its safety functions.
Control logic, operator screens and supervisory systems built and configured with security in mind.
Brokered, logged and time-limited remote access for integrators and equipment vendors.
Replacement of unsupported controllers and operating systems, planned around production windows.
Testing against the agreed requirements, as-built documentation and training for your team.
Typical applications
Configuration envelope
| Parameter | Options |
|---|---|
| Controllers | PLC, PAC, safety controllers and distributed I/O |
| Supervision | HMI, SCADA and historian systems |
| Networks | Industrial Ethernet and fieldbus, defined per site |
| Remote access | None, brokered vendor access or monitored sessions |
| Scope | New systems, upgrades or existing installations |
| Safety | Designed with reference to the safety standards that apply to your site |
Specifications are defined per program. The table describes the configuration options we work within, not fixed product specifications.
Process
Your operations, constraints and risks, captured as clear and measurable requirements.
What is actually there: assets, connections, access and procedures, reviewed with your team.
Architecture, priorities and trade-offs, reviewed with you before anything is changed or built.
Changes put in place in planned windows and tested against the agreed requirements.
Documentation, training for your team and ongoing support.
