Critical infrastructure is crucial for society to work.
It encompasses sectors vital for our society's functionality, ranging from transportation and energy to healthcare and communication.
Recognising the significant role each sector plays in our daily lives is crucial in appreciating the complexity and interconnectedness of our infrastructure systems.
By delving deeper into what constitutes critical infrastructure, we gain a deeper understanding of the essential services that support our society's operations.
Such awareness not only fosters a sense of appreciation but also highlights the importance of safeguarding and maintaining these sectors to ensure the well-being and security of all individuals.
What is critical infrastructure?
Critical infrastructure is understood as infrastructure–including facilities, systems, processes, networks, technologies, assets, and services–which are necessary to maintain or restore socially important functions.
Critical infrastructure is often defined differently from country to country. Although there are some common elements typically included in the definition of critical infrastructure, such as energy, water supply, transportation, communication, and healthcare, the specific details and priorities can vary depending on national circumstances and security needs.
E.g. the German definition is:
"Critical infrastructures (KRITIS) are organisations and facilities of major importance for society whose failure or impairment would cause a sustained shortage of supplies, significant disruptions to public order, safety and security or other dramatic consequences."
The UK definition is:
a) "Major detrimental impact on the availability, integrity or delivery of essential services - including those services whose integrity, if compromised, could result in significant loss of life or casualties - taking into account significant economic or social impacts; and/or
b) Significant impact on national security, national defence, or the functioning of the state.”
The Danish description is:
"Infrastructure, including facilities, systems, processes, networks, technologies, assets, and services that are essential to maintain or restore critical societal functions"
Although there is overlap between countries, the different definitions reflect national priorities and risk assessments. This means that policies and strategies for protecting critical infrastructure can vary significantly from country to country.
What constitutes critical infrastructure is determined by the authorities based on a division of society into socially important sectors, which further include several underlying socially important functions.
The ecosystem of critical infrastructure
Critical infrastructure plays a vital role in maintaining the functioning of society and the economy.
These assets, systems, and networks are essential for our way of life and are categorised into different sectors.
Protecting critical infrastructure is of utmost significance as any threat to these sectors could have potentially debilitating consequences for national security, the economy, and public health and safety.
These sectors are interconnected, forming a complex ecosystem where disruptions in one sector can impact others.
The three interwoven elements
Physical, cyber, and human are the three fundamental facets of critical infrastructure.
These interconnected aspects are explicitly identified and should always be considered integrated throughout the steps of the framework, when appropriate. Understanding and safeguarding critical infrastructure requires recognising the interplay between these facets.
This holistic approach is crucial for effective risk management and resilience planning, ensuring comprehensive protection of our essential systems.
Industries within the critical infrastructure sectors
Many people may not be aware of what constitutes critical infrastructure. It encompasses a variety of industries essential to the functioning of our society, including:
Suppliers and distributors of drinking water and wastewater companies that collect, dispose of, or treat urban wastewater, domestic wastewater, or industrial wastewater.
Industries concerning transportation, such as airport traffic management, railways, port operating bodies, operators of smart charging services for electrical vehicles.
Companies that manage waste handling.
Providers of digital infrastructure, such as telecommunications and internet exchange points.
Energy industries, such as utility companies within gas, transmissions and system operators within electricity, district heating operators, and operators within hydrogen production.
Understanding the diverse sectors within critical infrastructure highlights their importance in maintaining societal functions. Each industry plays a vital role in ensuring our safety, health, and general well-being.
Management within the critical infrastructure segments
Effective management within critical infrastructure segments is essential for ensuring operational continuity, security, and resilience.
By implementing robust management practices, organisations can better coordinate resources, mitigate risks, and respond swiftly to incidents.
Optimising deployment for critical infrastructure
In the realm of critical infrastructure, deployment plays a pivotal role in ensuring seamless operations across various sectors. From water supply and waste management to railways and fiber optical, these interconnected sectors form the backbone of our society.
Efficient deployment strategies secure operational continuity and enhance resilience against potential disruptions. By optimising resource allocation and leveraging technologies, organisations can strengthen their critical infrastructure against emerging threats.
To stay ahead of the curve, prioritise deployment frameworks that align with the unique needs of each sector, safeguarding the foundation of our modern world.
The crucial role of maintenance
Many sectors within critical infrastructure rely on the supply of e.g. electricity to keep operations running smoothly and prevent chaos.
Maintenance activities maintain the reliability and resilience of all the systems we depend upon—from transport and energy, through telecommunications and health.
These sectors can maintain safety standards by anticipating maintenance requirements and addressing issues as they arise, increase efficiency, and prolong the life of essential equipment through a test and repair or replace mentality.
Good maintenance practices also improve operational effectiveness, and they save a lot of money in the long run.
The importance of infrastructure maintenance in our daily lives lies in preserving public health and functionality, while ensuring continuous access to essential services and future resources.
The importance of a localisation-based subcontractor overview
Localisation capabilities are vital for the success of deployment and maintenance projects in critical infrastructure.
Accurate localisation allows for precise placement and repair of equipment, reducing downtime, and improving efficiency of your workforce and subcontractors.
Comprehensive documentation ensures that all steps are tracked and reproducible, while effective tools and inventory management reinsures that necessary resources are readily available.
In fact, effective subcontractor management is crucial for critical infrastructure owners, leading to increased efficiency, optimised resource allocation, and enhanced coordination, collaboration, and documentation.
Ensuring that subcontractors easily can update tasks, take photos, fulfill checklist requirements, and sign documents enhances supervision and quality control, which is vital for maintaining the reliability and safety of critical infrastructure projects.

Critical infrastructure protection with NIS2
NIS2's implementation aims to enhance operational continuity and resilience, ensuring robust protection against emerging cyber threats.
By enforcing stricter security requirements and comprehensive risk management, NIS2 aims to maintain the stability and functionality of the infrastructure we rely on every day.
Overview of NIS2
The EU has adopted the Network and Information Security Directive (NIS2), which aims to strengthen cybersecurity across member states.
NIS2 introduces stricter requirements for management, minimum standards for handling cyber risks, mandatory notification of security incidents within 24-72 hours, and substantial fines for non-compliance.
It represents the most comprehensive cybersecurity framework to date, though not exhaustive in specifying all derived security requirements for companies.
This directive will be supplemented by the Critical Entities Resilience Directive (CER), focusing on physical security measures. While NIS2 creates a unified approach across various sectors, the energy, finance, and telecommunications sectors will implement these regulations separately.
