OT Network Security
OT Network Security focuses on protecting the communication infrastructure used by industrial control systems.
TOSOG can assist with network security strategies such as network segmentation, firewall implementation, secure remote access, traffic monitoring, access control, and network visibility.
Separating critical control networks from business IT networks can help reduce the risk of threats moving between environments.
SCADA Cyber Security
SCADA systems are widely used for monitoring and controlling industrial processes.
Our SCADA Cyber Security approach can help organisations identify weaknesses across SCADA servers, HMIs, engineering workstations, communication networks, remote access systems, and connected industrial devices.
Security measures can include:
- SCADA network segmentation
- Firewall protection
- Secure remote access
- User access controls
- Network monitoring
- Asset identification
- Vulnerability management
- Backup and recovery planning
- Security monitoring
PLC Cyber Security
Programmable Logic Controllers (PLCs) are fundamental components of industrial automation systems.
Protecting PLC environments requires consideration of both cybersecurity and operational requirements. TOSOG can assist with security measures around PLC networks, engineering workstations, communication protocols, remote access, and network architecture.
Security improvements should be implemented carefully to avoid disrupting critical industrial processes.
IT/OT Security
The convergence of Information Technology (IT) and Operational Technology (OT) creates new opportunities for data sharing, remote monitoring, analytics, and operational efficiency.
However, poorly secured connections between IT and OT environments can increase cyber risk.
TOSOG can help organisations develop a more secure IT/OT architecture by identifying network boundaries, reviewing communication paths, implementing segmentation, and improving access controls.
Industrial Network Segmentation
OT Network Segmentation can help limit the spread of cyber threats within industrial environments.
Depending on the operational requirements, networks can be separated into appropriate security zones, such as:
- Enterprise IT Network
- Industrial DMZ
- Supervisory Network
- Control Network
- PLC Network
- Safety Systems
- Remote Access Network
The exact architecture should be based on the facility, equipment, processes, risk profile, and operational requirements.
Industrial Cyber Security Assessment
A Cyber Security Assessment can provide organisations with a clearer understanding of their current OT security posture.
An assessment may review:
- Industrial assets and devices
- Network architecture
- IT/OT connectivity
- Remote access
- User accounts and permissions
- Firewall configuration
- Network segmentation
- Vulnerability exposure
- Backup arrangements
- Security monitoring
- Incident response capabilities
- Existing cybersecurity policies
The results can be used to prioritise security improvements according to operational risk and business requirements.

Why Industrial OT Security Matters
Traditional IT security approaches do not always address the specific requirements of OT environments.
Industrial systems often prioritise:
- Availability
- Safety
- Reliability
- Deterministic operation
- Long equipment lifecycles
- Process continuity
A cybersecurity strategy for OT therefore needs to consider both cybersecurity risk and operational requirements.
The objective is not simply to add security controls, but to improve protection without unnecessarily disrupting industrial processes.
Tips for Improving OT Cyber Security
1. Know Your Industrial Assets
Maintain an accurate inventory of PLCs, SCADA systems, HMIs, servers, switches, routers, remote access systems, and other connected OT assets.
2. Separate IT and OT Networks
Where appropriate, use segmentation and controlled communication between enterprise IT and industrial OT environments.
3. Secure Remote Access
Remote connections should be carefully controlled, authenticated, monitored, and limited to authorised users and systems.
4. Control User Access
Apply the principle of least privilege so users only receive the access required for their responsibilities.
5. Monitor OT Networks
Network monitoring can help identify unusual traffic, unauthorised devices, and potentially suspicious activity.
6. Protect Engineering Workstations
Engineering workstations can provide access to critical control systems and should receive appropriate security controls.
7. Maintain Reliable Backups
Keep secure backups of critical configurations, software, system images, and other information required for recovery.
8. Manage Legacy Equipment Carefully
Older PLCs, HMIs, operating systems, and industrial devices may have limited security capabilities. Compensating controls and network segmentation can help reduce associated risks.
9. Develop an Incident Response Plan
Know what your organisation will do if an OT cybersecurity incident occurs, including escalation procedures and recovery priorities.
10. Avoid Unplanned Changes
Cybersecurity changes in OT environments should be carefully assessed, tested, and scheduled to minimise operational disruption.
