H1: ICS and SCADA: Common Risks and Solutions

Industrial operations face an evolving technology landscape posing distinct reliability, connectivity, data integration, and security challenges. Gaps emerge as infrastructure meshes cyber and physical systems more tightly across manufacturing, utilities, transportation, and other sectors.

While ICS/SCADA systems have long lifespans, they are often installed and forgotten until a problem emerges. Maintenance is often limited to calibrating instruments and doing periodic reviews to ensure things are operating properly. The world has changed a lot in the past decade, yet the majority of systems are now more than 10 years old—built before many of today’s modern technologies and risks existed.

Here are some of the complexities facing organizations today with their ICS and SCADA systems.

Technology Obsolescence

Challenges and Risks

Many industrial environments rely on aging infrastructure that has been in use for a long time, including programmable logic controllers (PLCs), human-machine interfaces (HMIs), and remote terminal units (RTUs). While reliable, this equipment lacks the modern system resources and software capabilities that companies now require.

The proprietary nature and purpose-built designs of these systems can hinder integration with newer IT systems. Moreover, the high cost of full ICS/SCADA replacements leads organizations to delay upgrades.

Solutions

• Create lifecycle roadmaps for the gradual modernization of aging devices
• Align new purchases with the latest industry standards and security features
• Integrate legacy components into secure network enclaves
• Test compatibility of upgrades through simulations before deployment

Network and Communication Disruptions

Challenges and Risks

Challenging physical environments combined with serial protocols predating IT standards can create fragile communications channels. Links face disruptions from temperature swings, moisture, vibrations, and electromagnetic interference, degrading connectivity hardware. This loss of visibility and control capabilities affects operational stability.

Determining the root causes of network disruptions often proves difficult, given the interdependencies spanning IT and operations teams.

Solutions

• Install industrial-grade cabling, switches, and routers
• Incorporate redundant wired or wireless links
• Standardize on IP networking with VLAN segmentation
• Closely monitor traffic with analytics for early warning

Data Management Difficulties

Challenges and Risks

ICS SCADA systems collect significant amounts of operational data tied to specific control system elements. Yet, complications can result from attempting to extract, standardize, store, and analyze this information across multiple proprietary platforms.

That makes it difficult to see the comprehensive overview required for operational intelligence.

Solutions

• Implement centralized data lakes and warehouses for ICS/SCADAsystems
• Leverage IIoT platforms built for industrial environments
• Apply analytics and machine learning capabilities
• Create unified dashboards and visualizations
• Enrich data with additional sources like weather feeds

Cybersecurity Risks

Challenges and Risks

Attacks on ICS SCADA systems have increased substantially over the past few years. Many industrial control systems lack security by design. At the same time, new sensors and IIoT devices are expanding the potential attack surface, and operators are doing more via remote access.

Many legacy sites rely on operating systems no longer supported with patches to secure vulnerabilities. In some cases, authentication mechanisms were put in place before threats like ransomware even existed.

IoT devices often lack built-in security, yet reside within your network’s perimeter. This exposes facilities to avoidable disruptions.

Solutions

• Align with standards like IEC 62443and NIST 800-53
• Implement secure remote access via VPNs
• Develop policies and training to boost security awareness
• Perform regular penetration testing and audits
• Deploy next-generation antivirus and monitoring tools

Compliance Requirements

Challenges and Risks

Industrial organizations often struggle to balance production and operational imperatives with emerging regulations aimed at critical infrastructure owners. Compliance scope creep introduces added documentation burdens while audit failures can have serious financial and reputational repercussions. Yet, many traditional operational environments lack governance frameworks attuned to these external reporting mandates.

Solutions

• Perform gap analyses highlighting policy and technology holes
• Build a controls matrix cataloging required safeguards
• Detail incident response plans and reporting procedures
• Create audit prep agendas including people, process, and technology

Overcoming ICS SCADA Challenges and Risks

While individual solutions help overcome the challenges and risks in your ICS/SCADA ecosystem, you need a comprehensive roadmap that aligns OT, IT, and security under a unified umbrella. You need an experienced industrial control system (ICS) integrator to help you navigate the common challenges and risks to deploy solutions that work for your unique environment.
