What is ICS cybersecurity and who needs it?

The importance of ICS cybersecurity is highlighted with a focus on protecting critical systems across various sectors, including manufacturing, energy, oil and gas, transportation, and government, emphasizing the shared responsibility in safeguarding against cyber threats.

ICS cyber security is the protection of industrial control systems. These systems monitor and control physical processes in environments such as manufacturing, energy, water, chemicals, utilities, transport and infrastructure.

ICS may include PLCs, DCS, SCADA, HMIs, safety systems, engineering workstations, historians and industrial networks. If these systems are disrupted or manipulated, the impact can be operational rather than purely digital.

Who needs ICS cyber security?

Any organisation that depends on automated control, monitoring or industrial process data needs ICS cyber security. This includes large critical infrastructure operators, small manufacturers, utilities, food and beverage plants, energy sites, chemical facilities, water treatment sites and companies with connected machinery.

The level of security required should be proportionate to the risk, but ignoring ICS security is no longer realistic.

What ICS cyber security includes

It includes asset inventory, risk assessment, network segmentation, access control, secure remote access, patch and vulnerability management, backups, incident response, monitoring, secure system design and staff awareness.

It also includes governance: policies, roles, procedures, documentation and continuous improvement.
