ICS/OT Cybersecurity Implementation
Our Implementation service turns assessment findings and architecture designs into operational security controls. We deploy, configure, and validate every component on-site, working within maintenance windows and operational constraints to deliver hardened infrastructure with zero production impact.
From Assessment to Operational Controls
Assessment reports identify what needs to change. Implementation makes it happen. Our implementation service takes assessment findings and architecture designs and turns them into deployed, validated, and operational security controls on your production floor.
We work within your operational constraints: maintenance windows, change management processes, vendor coordination, and production schedules. Every change is planned with a rollback procedure and validated against process requirements before, during, and after deployment.
What We Deploy
- IDS and IPS with protocol-aware detection
- Industrial firewall configuration and allow-list rule design
- Network segmentation and zone enforcement
- Managed switch and device hardening
- Secure Remote Access (SRA) platform deployment
- Patch and firmware update implementation
- System-level hardening and validation
Execution Focused
Deploying security controls that work within operational constraints
Engagement Methodology
A structured, phased approach designed for the safety, availability, and compliance requirements of operational technology environments.
Scope and Readiness Assessment
Review the current network architecture, existing equipment, and implementation plan. Identify dependencies, define maintenance windows, prepare rollback procedures, and establish success criteria for each implementation phase.
IDS and IPS Deployment
Deploy intrusion detection and prevention systems at strategic network points. Configure protocol-aware detection for industrial protocols (Modbus, OPC-UA, EtherNet/IP, DNP3). Tune detection rules against baseline traffic to minimize false positives while maintaining threat visibility.
Firewall Configuration and Rule Design
Configure industrial firewalls with explicit allow-list rule sets based on validated traffic flows. Replace default permit-all policies with documented, justified rules. Implement protocol-level deep packet inspection for OT protocols at zone boundaries.
Network Segmentation Enforcement
Implement zone and conduit architecture across the OT network. Configure VLANs, ACLs, and firewall rules to enforce segmentation between security zones. Validate all legitimate communication flows after enforcement with a structured observation period.
Switch and Device Hardening
Harden managed switches and network devices: disable unused ports, enable port security with MAC limiting, replace default credentials, disable insecure protocols (Telnet, SNMPv1/v2), enable logging and syslog forwarding, and apply configuration baselines.
Secure Remote Access Deployment
Deploy and configure a centralized secure remote access (SRA) platform. Implement MFA, individual credentials, session recording, scheduled access windows, and role-based access controls. Eliminate direct VPN or RDP connections to production systems.
Patch Management and System Hardening
Implement a structured patch management process with risk-based evaluation, vendor coordination, and maintenance window scheduling. Apply OS and application hardening baselines to workstations, servers, and HMIs. Validate all changes against operational requirements before and after deployment.
Service Deliverables
- IDS/IPS deployment with tuned detection rules
- Hardened firewall configurations with documented rule sets
- Network segmentation implementation with zone validation
- Switch hardening baselines applied across all managed devices
- Secure remote access platform with configured access policies
- Patch management process and system hardening documentation
- Post-implementation validation report
