Industrial Remote Access Security

Industrial & OT Cyber Security

TOSOG provides Industrial Remote Access Security solutions designed to help protect industrial control systems, operational technology (OT), critical infrastructure, and connected industrial environments from cyber threats.

Industrial environments are increasingly connected through PLCs, SCADA systems, HMIs, DCS platforms, RTUs, industrial networks, remote access systems, and IIoT devices. While connectivity improves visibility and operational efficiency, it also introduces new cybersecurity risks.

Our Industrial Remote Access Security services help organisations identify vulnerabilities, strengthen industrial networks, improve access controls, and establish practical cybersecurity measures without unnecessarily disrupting critical operations.

What Is Industrial & OT Cyber Security?

Industrial and OT Cyber Security focuses on protecting the technology and systems used to monitor, control, and operate physical processes.

Unlike traditional IT environments, OT systems often prioritise availability, safety, reliability, and continuous operation. Cybersecurity measures therefore need to be carefully planned around operational requirements.

Industrial & OT Cyber Security Services

Our Industrial Remote Access Security services can be tailored to the requirements of your industrial environment.

OT Cyber Security Assessment

Identify potential cybersecurity weaknesses within your operational technology environment.

Assessments can include network architecture, connected devices, remote access, user privileges, industrial protocols, system configurations, and potential attack surfaces.

Industrial Network Security

Improve the security and resilience of industrial networks through appropriate segmentation, access controls, monitoring, and network architecture.

Solutions can be designed for environments incorporating industrial Ethernet, managed switches, VLANs, firewalls, PLCs, SCADA systems, and other automation equipment.

OT Network Segmentation

Network segmentation can help limit the spread of cyber threats between corporate IT systems and operational technology environments.

TOSOG can assist with developing practical segmentation strategies for industrial networks and critical control systems.

Industrial Firewall Solutions

Deploy appropriate firewall technologies to control communications between IT, OT, remote-access, and industrial network zones.

Firewall configurations should be carefully designed to maintain required industrial communications while restricting unnecessary network traffic.

Secure Remote Access

Remote access can be essential for maintenance, troubleshooting, monitoring, and technical support.

Our Industrial Remote Access Security approach helps organisations establish controlled remote access using appropriate authentication, permissions, monitoring, and security controls.

Vulnerability Identification

Identify potential weaknesses in industrial systems, network architecture, software, devices, and access controls.

Where appropriate, assessments can be performed with consideration for the sensitivity of operational equipment and the need to avoid unnecessary disruption.

Industrial Asset Visibility

Understanding what is connected to an OT network is an important part of cybersecurity.

We can help organisations develop greater visibility of industrial assets, including PLCs, HMIs, SCADA servers, switches, engineering workstations, RTUs, and other connected equipment.

OT Security Monitoring

Industrial environments can benefit from continuous monitoring of network activity, system events, authentication attempts, and unusual communications.

Security monitoring can help organisations identify suspicious activity and respond more quickly to potential incidents.

Cyber Security for PLC & SCADA Environments

PLCs and SCADA systems are critical components of many industrial operations.

Our Industrial Remote Access Security services can support cybersecurity planning around automation systems while considering operational availability and system dependencies.

OT Incident Response Planning

A cybersecurity incident affecting an industrial environment can have operational consequences.

We can assist organisations with developing practical response procedures covering incident identification, escalation, isolation, recovery, and communication.

IT Cyber Security vs OT Cyber Security

IT and OT cybersecurity share many security principles, but their priorities can differ.

A cybersecurity strategy for an industrial environment should therefore account for the operational consequences of security changes.

Our Approach to Industrial OT Cyber Security

TOSOG takes a practical approach to Industrial Remote Access Security:

1. Understand
We first establish an understanding of the industrial environment, systems, network architecture, and operational requirements.

2. Identify
Potential vulnerabilities, exposed systems, unnecessary access, and network security gaps are identified.

3. Prioritise
Security improvements are prioritised according to operational importance, risk, and business requirements.

4. Protect
Appropriate controls can include segmentation, firewalls, secure remote access, authentication, monitoring, and configuration improvements.

5. Monitor
Industrial environments should be monitored for unusual activity and emerging cybersecurity risks.

6. Improve
Cybersecurity should be treated as an ongoing process rather than a once-off project.

Tips for Improving Industrial & OT Cyber Security

1. Know What Is Connected

Maintain an accurate inventory of PLCs, HMIs, SCADA servers, switches, RTUs, engineering workstations, and other OT devices.

2. Separate IT and OT Networks

Avoid unnecessary direct connectivity between corporate IT networks and industrial control systems.

3. Control Remote Access

Remote access should only be available to authorised users and should be properly secured and monitored.

4. Use Strong Authentication

Implement appropriate authentication and access controls, particularly for privileged and remote users.

5. Minimise Unnecessary Access

Users and systems should only have the access required to perform their responsibilities.

6. Back Up Critical Systems

Maintain secure backups of important configurations, programs, databases, and system information where appropriate.

7. Document Your OT Environment

Keep network diagrams, asset information, IP addresses, system dependencies, and recovery procedures up to date.

8. Plan Before Applying Security Changes

Cybersecurity changes in OT environments should be carefully assessed because poorly planned changes can affect production or control systems.

9. Monitor Industrial Networks

Monitoring can help identify unusual communications, unexpected devices, and suspicious activity.

10. Develop an Incident Response Plan

Know what your organisation will do if an industrial control system or OT network is compromised.

Frequently Asked Questions

What is OT Cyber Security?

OT Cyber Security is the practice of protecting operational technology systems used to monitor and control physical industrial processes from cyber threats, unauthorised access, system compromise, and other security risks.

Why is OT Cyber Security important?

OT systems can directly influence industrial operations and physical processes. A cybersecurity incident can therefore affect production, availability, safety, equipment, and business continuity.

Depending on the environment, OT security can cover PLCs, SCADA, HMIs, DCS, RTUs, industrial networks, industrial switches, control systems, engineering workstations, servers, remote access systems, and IIoT devices.

Can TOSOG secure an existing industrial network?

Yes. Existing industrial environments can be assessed to identify potential security improvements while considering operational requirements and system dependencies.

Does OT Cyber Security affect production?

Security changes should be carefully planned and implemented to minimise operational disruption. OT environments require a different approach from conventional IT systems because availability and reliability are critical.

Can you secure PLC and SCADA systems?

Yes. Industrial Remote Access Security can include security considerations for PLC, SCADA, HMI, DCS, RTU, and other industrial automation environments.

Is network segmentation important for OT?

Yes. Proper segmentation can help separate critical OT systems from other networks and reduce unnecessary communication paths and potential attack surfaces.

Do industrial systems need remote access security?

Where remote access is required, it should be properly controlled, authenticated, authorised, monitored, and secured.

How often should an OT cybersecurity assessment be performed?

The appropriate frequency depends on the organisation, system criticality, changes to the environment, regulatory requirements, and risk profile. Assessments should also be considered following significant network or system changes.
