The National Cybersecurity System (NCS) serves as a protective shield for Polish critical infrastructure, aiming to protect against cyber threats that could endanger the stability of key sectors such as energy, transport, and healthcare. The system coordinates cooperation between public institutions, key service operators, and digital service providers, while also ensuring rapid incident response. NCS is of key importance for the country’s digital security.
What is the National Cybersecurity System and What is Its Role in Protecting Critical Infrastructure?
The National Cybersecurity System (NCS) is a comprehensive ecosystem of cooperation, information exchange, and coordination of activities between key entities responsible for cybersecurity of the Republic of Poland. The main goal of NCS is to ensure uninterrupted functioning of critical infrastructure, key services, and digital services, as well as to achieve a high level of security of ICT systems upon which the smooth operation of the state and economy depends.
NCS serves as a protective shield for Polish critical infrastructure, covering systems for energy supply, energy resources and fuels, communications, ICT networks, financial systems, food supply, water supply, healthcare, transport, rescue services, ensuring continuity of public administration operations, and production, storage, keeping, and use of chemical and radioactive substances, including pipelines for hazardous substances. Through continuous threat monitoring, risk analysis, coordination of activities, and rapid incident response, NCS minimizes the risk of disruptions in the functioning of these critical systems, which are the foundation of the country’s security and development.

What are the Key Elements of the National Cybersecurity System?
The National Cybersecurity System consists of four main pillars:
-
Computer Security Incident Response Teams (CSIRTs) - CSIRT NASK, CSIRT GOV, and CSIRT MON, responsible for incident handling, coordination of activities, and cooperation with domestic and international entities.
-
Key service operators (e.g., energy companies, transport, banks, healthcare) and digital service providers (e.g., cloud computing, internet search engines, trading platforms), obligated to implement security measures and report serious incidents.
-
Sectoral cybersecurity teams - formed by key service operators from a given sector, serving to exchange information and good practices and develop security standards.
-
Single Point of Contact - ensuring cooperation with European Union institutions and member states in the field of cybersecurity.
An important role is also played by competent authorities for cybersecurity (ministers and heads of central offices), supervising the implementation of NCS Act requirements in their sectors. The entire system is managed by the Government Plenipotentiary for Cybersecurity, responsible for coordinating policy and activities at the national level.
How Does the National Cybersecurity System Identify Threats to Critical Infrastructure?
The National Cybersecurity System uses a range of mechanisms to identify threats to critical infrastructure. A key role is played by continuous monitoring of ICT systems conducted by CSIRT teams. They use advanced tools to detect anomalies in network traffic, intrusion attempts, presence of malicious software, or vulnerabilities in systems.
An important source of threat information is also the exchange of threat intelligence data between NCS participants and domestic and foreign partners. This enables early identification of new trends, techniques, and tools used by cybercriminals, as well as specific groups and campaigns targeting Polish infrastructure.
NCS also conducts regular risk assessments at national, sectoral, and individual entity levels. These consider not only technical factors but also geopolitical, social, and economic conditions. The results of these analyses help identify the most critical assets and services and prioritize protective actions.
The constant threat monitoring conducted by key service operators within implemented information security management systems is also significant. They are obligated to identify and assess risks to provided services, implement adequate safeguards, and detect and report incidents.
How Does the Early Warning System for Cyberattacks Work Within NCS?
The early warning system for cyberattacks is a key element of proactive critical infrastructure protection within the National Cybersecurity System. It is based on continuous threat monitoring conducted by CSIRT teams, in cooperation with key service operators, cybersecurity service providers, and domestic and international partners.
When CSIRTs identify a new threat (e.g., a phishing campaign, zero-day exploit, botnet targeting Polish systems), they immediately prepare an alert containing a description of the threat, potential consequences, and recommendations for remedial actions. The alert is then distributed through dedicated communication channels to all NCS entities potentially exposed to the given threat.
CSIRT GOV plays a special role here, being responsible for early warning of public administration and critical infrastructure operators. It uses, among others, the S46 platform for automatic distribution of alerts, recommendations, and indicators of compromise, enabling rapid implementation of protective measures on a wide scale.
Sectoral cybersecurity teams are also an important element of the system, ensuring smooth information flow and coordination of activities within individual industries. This allows for adapting alerts to the specifics of a given sector and prioritizing actions based on the criticality of individual services.
The effectiveness of the early warning system is regularly tested through exercises and simulations, with the participation of all stakeholders. This helps improve procedures, strengthen cooperation, and build trust - key for effective communication in crisis situations.
What Monitoring and Risk Analysis Tools Does NCS Use?
The National Cybersecurity System uses a wide spectrum of advanced tools for threat monitoring and risk analysis. At the technical layer, these are primarily SIEM (Security Information and Event Management) class systems, used to collect, correlate, and analyze logs from various sources in real-time. They enable detection of anomalies, tracking suspicious activities, and identifying potential incidents at an early stage.
IDS/IPS (Intrusion Detection/Prevention Systems) also play an important role, monitoring network traffic for signatures of known attacks and behavioral anomalies. These are complemented by advanced malware analysis solutions (sandboxing), enabling safe detonation of suspicious files and identification of new threats.
At the strategic level, NCS applies risk analysis methodologies based on recognized standards, such as ISO 27005, NIST SP 800-30, or OCTAVE. These consider not only technical factors but also business, legal, and social conditions. Key importance is placed on identifying and valuing key assets, assessing vulnerabilities and potential incident consequences, and estimating the probability of their occurrence.
The risk analysis process is supported by dedicated software platforms, such as PILAR or MSAT. These enable automation of tedious tasks, visualization of results, and report generation. An important trend is also the use of machine learning and artificial intelligence for more proactive threat identification and security measure optimization.
Monitoring and risk analysis results are continuously aggregated and processed by the Single Point of Contact, responsible for the overall picture of the country’s cybersecurity situation. The S46 platform enables automatic data exchange between NCS participants, facilitating coordination of activities and making strategic decisions.
How Does NCS Coordinate Activities of Various Institutions in Critical Infrastructure Protection?
Effective protection of critical infrastructure requires close cooperation and coordination of activities of many entities - public and private, operating at different levels and in different sectors. The National Cybersecurity System provides organizational frameworks and tools for efficient management of this complex network of stakeholders.
The Government Plenipotentiary for Cybersecurity plays a key role, responsible for coordinating policy and activities at the national level. They chair the Cybersecurity College, a platform for cooperation and information exchange between ministries, special services, and sectoral regulators. The College develops strategic assumptions and recommendations, which are then implemented by individual administration bodies.
At the operational level, coordination is ensured by CSIRT teams, acting as a single point of contact for NCS entities. CSIRT GOV is responsible for cooperation with public administration and critical infrastructure operators, CSIRT NASK - for contacts with the private sector and citizens, and CSIRT MON - for the military area. These teams work closely together, exchanging information and coordinating activities in case of serious incidents.
Sectoral cybersecurity teams, formed by key service operators from a given industry, are also an important coordination mechanism. They provide a platform for exchanging experiences, developing common standards and procedures, and rapid information flow in case of threats specific to a given sector.
Cooperation agreements concluded by NCS participants with key stakeholders, such as cybersecurity service providers, research centers, or non-governmental organizations, are also significant. They provide access to specialized knowledge and resources, as well as building trust and understanding for common goals.
All these activities are supported by dedicated tools, such as the S46 platform for automatic data exchange or the early warning system. Thanks to them, information about threats and incidents can be instantly distributed to all relevant entities, enabling smooth coordination of preventive and remedial actions.
How Does the Incident Response Process for Cybersecurity Incidents Affecting Critical Infrastructure Proceed?
Efficient and effective response to cybersecurity incidents is a key element of critical infrastructure protection. The National Cybersecurity System defines clear procedures and roles of individual entities in this process, in accordance with a risk management and business continuity approach.
The response process begins with incident detection - whether through the key service operator’s monitoring systems or by CSIRT teams as part of conducted monitoring. After initial analysis and incident classification (based on its scale, scope, and potential consequences), the appropriate escalation path is triggered.
Serious incidents affecting critical infrastructure are immediately reported to the appropriate national-level CSIRT (GOV, NASK, or MON). This team takes over coordination of activities, triggering dedicated crisis response procedures. These include, among others, establishing a crisis staff, notifying key stakeholders, securing evidence, analyzing incident causes and effects, and developing and implementing a remediation plan.
Depending on the scale and nature of the incident, the CSIRT may also activate additional support - whether from other national teams, cooperating foreign CSIRTs, or specialized commercial firms. Key importance is placed on rapid and efficient information exchange, enabling full understanding of the situation and coordination of all involved parties’ activities.
In parallel, the key service operator triggers their own response procedures, in accordance with the implemented incident management system. These include, among others, notifying management, activating the response team, implementing damage-limiting measures (e.g., isolating infected systems), and then restoring a safe state and resuming normal service operation.
Communication is an important element of the process - both internal (within the organization affected by the incident) and external (with administration bodies, media, public opinion). NCS provides support here through dedicated channels and tools, as well as coordinated activities of press spokespersons and crisis communication experts.
After the direct response ends, conducting a thorough post-incident analysis is key. Its goal is to fully understand the causes, course, and consequences of the incident, as well as to identify weaknesses and areas requiring improvement - both at technical and organizational levels. Conclusions from this analysis are then implemented in the form of specific recommendations and changes to security systems.
The entire process is documented in detail, and key information and “lessons learned” are shared with other NCS participants - whether through the S46 platform or at sectoral cybersecurity team forums. This enables continuous improvement of the national incident response system and raising the overall level of critical infrastructure cybersecurity.
What Security Standards and Guidelines Does NCS Introduce for Critical Infrastructure Operators?
The National Cybersecurity System, aiming to ensure a high and consistent level of critical infrastructure protection, introduces a range of standards and guidelines that must be followed by key service operators. They constitute a kind of “foundation” of security, upon which further solutions specific to a given sector or organization are built.
A key document is the Act on the National Cybersecurity System, which defines, among others, operator obligations regarding implementing security management systems, reporting and handling incidents, and cooperating with CSIRTs. The Act is supplemented by a series of implementing regulations, specifying requirements in individual areas.
International norms and standards recommended by NCS as good practices also play an important role. These include:
-
ISO/IEC 27001 - specifying requirements for information security management systems.
-
NIST Cybersecurity Framework - defining key functions and categories of activities in cybersecurity.
-
NIST SP 800-82 - containing guidelines for industrial control system (ICS) security.
-
NIST SP 800-53 - describing security controls for information systems.
-
IEC 62443 - specifying security requirements for industrial automation systems.
NCS also promotes the use of recognized risk management methodologies (e.g., OCTAVE, CRAMM, MAGERIT), business continuity (e.g., ISO 22301), and incident response (e.g., NIST SP 800-61).
Beyond general frameworks, NCS also develops detailed guidelines and recommendations dedicated to individual critical infrastructure sectors. They consider the specifics of a given industry, typical threats, and good practices. Examples include security guidelines for water supply systems, rail transport, or healthcare.
All these standards and guidelines are regularly updated in response to the evolving threat landscape and technological progress. NCS works closely with operators, industry experts, and scientific centers to ensure their adequacy and feasibility.
It is worth emphasizing that NCS standards are not just “dry” technical requirements, but also guidelines for building a security culture in organizations. They include, among others, training and raising employee awareness, implementing secure software development processes, managing supplier relationships, and secure use of cloud services.
Applying NCS standards and guidelines, although often demanding and costly, brings measurable benefits to critical infrastructure operators. Beyond the obvious raising of security level, it also facilitates meeting regulatory requirements, improves reputation and customer trust, and often also optimizes processes and reduces operational costs. This is an investment that in today’s digital world is becoming a business necessity.
How Does NCS Support Critical Infrastructure Operators in Raising Cybersecurity Level?
The National Cybersecurity System, beyond setting requirements, also offers critical infrastructure operators broad support in raising cybersecurity level. This includes both strategic-level activities and practical help in daily security management.
A key form of support is sharing knowledge and information about threats. CSIRT teams, in cooperation with domestic and international partners, constantly monitor cyberspace in search of new trends, attack techniques, and vulnerabilities. Obtained data is analyzed and processed into practical recommendations, alerts, and indicators of compromise (IOC), which then reach operators through dedicated channels, such as the S46 platform.
NCS also organizes regular training, workshops, and conferences, allowing operators to expand knowledge, exchange experiences, and establish contacts. Topics include both technical issues (e.g., SCADA system security, incident management) and organizational issues (e.g., building security culture, compliance with regulations). Many of these events are organized in cooperation with leading academic centers and industry experts.
An important aspect is also support in building competencies. NCS, in cooperation with universities and training companies, develops educational and certification programs for cybersecurity professionals. These include both general qualifications (e.g., CISSP, CompTIA Security+) and sectoral specializations (e.g., industrial systems security). Operators can benefit from training subsidies for their employees, as well as assistance in talent recruitment.
NCS also offers support in testing and improving security measures. CSIRT teams conduct regular exercises and simulations, allowing operators to test their incident response procedures and identify areas for improvement. Penetration testing and security audit services are also available, performed by trusted commercial partners on preferential terms.
Financial support is also significant. Critical infrastructure operators can apply for funding for security investments from national and EU funds. NCS helps in identifying appropriate programs, preparing applications, and implementing projects. Priority is given to projects of systemic importance, contributing to raising the overall security level in a given sector.
Finally, NCS provides support in crisis situations. In case of a serious incident, operators can count on CSIRT team assistance in analyzing causes, limiting effects, and restoring a safe state. Legal and communication support is also available, facilitating crisis management and reputation protection.
All these forms of support have one goal - building partnership relations between NCS and critical infrastructure operators. Only through close cooperation, information exchange, and continuous improvement is it possible to effectively counter increasingly sophisticated threats in cyberspace. NCS here is not only a regulator but above all an ally and advisor, jointly caring for the security of key services for citizens and the economy.
What Does International Cooperation Within NCS in Critical Infrastructure Protection Look Like?
In an era of global interdependencies and cross-border threats in cyberspace, effective critical infrastructure protection requires close international cooperation. The National Cybersecurity System actively engages in this cooperation, both at the European Union level and within other organizations and agreements.
The basis for cooperation at the EU level is the NIS Directive (Network and Information Security), which establishes legal and organizational frameworks for ensuring a high level of security for networks and information systems in all member states. NCS, through the Single Point of Contact, actively participates in the work of the NIS Cooperation Group, serving to exchange information and good practices and coordinate cybersecurity policies.
The CSIRT network is also a key mechanism, enabling smooth information exchange and coordination of activities in case of cross-border incidents. Polish CSIRT teams work closely with counterparts from other EU countries, among others through the MISP (Malware Information Sharing Platform) platform or the threat early warning system.
NCS also actively engages in the work of the European Union Agency for Cybersecurity (ENISA). NCS experts participate in ENISA working groups and projects concerning, among others, critical infrastructure security, ICT product certification, or building member state capacity. Poland also has its representative on the ENISA Management Board, influencing the agency’s strategic directions.
Beyond cooperation within the EU, NCS also develops bilateral relations with key partners. Contacts with the USA are particularly intensive, with which Poland concluded an agreement on enhanced cooperation in cybersecurity in 2018. This includes, among others, exchange of information and experiences, joint exercises and training, as well as research and development projects. NCS also has similar agreements with the United Kingdom, Israel, or South Korea.
NATO is also an important cooperation forum. Poland, as an Alliance member, actively engages in the work of the Cooperative Cyber Defence Centre of Excellence (CCD COE) in Tallinn. NCS experts participate in the Centre’s training, exercises, and research projects, contributing to strengthening NATO’s cyber defense. NCS also supports the implementation of NATO’s cybersecurity policy, including the concept of collective defense in cyberspace.
NCS is also an active participant in global initiatives and organizations, such as the Internet Governance Forum (IGF), the International Telecommunication Union (ITU), or the Global CSIRT Forum. Participation in these bodies enables exchange of knowledge and experiences with partners from around the world, as well as shaping global standards and good practices in cybersecurity.
International cooperation within NCS brings measurable benefits for Polish critical infrastructure security. It enables faster detection and response to cross-border threats, access to unique knowledge and resources of partners, as well as influence on shaping policies and standards at European and global levels. This is a key element of building cyber resilience in an era when no state is a lonely island in cyberspace.
What are the Mechanisms for Exchanging Threat Information Between NCS Entities?
Efficient and secure exchange of threat information is the foundation of effective functioning of the National Cybersecurity System. It enables rapid detection, analysis, and response to incidents, as well as proactive building of resilience through sharing knowledge and good practices. NCS uses a range of mechanisms to ensure smooth data flow between all system participants.
The S46 platform plays a key role, serving for automatic exchange and analysis of threat information. It enables secure and standardized sharing of such data as indicators of compromise (IoC), malware descriptions, vulnerability data, or security recommendations. All NCS entities - from CSIRT teams, through key service operators, to cybersecurity service providers - are obligated to submit relevant information through S46.
Data entered into the platform is automatically correlated and analyzed, providing a comprehensive picture of the situation and facilitating identification of connections between seemingly distant incidents. NCS entities have access to personalized dashboards presenting information relevant to their sector or risk profile. They can also subscribe to alerts about new threats or receive dedicated security recommendations.
Beyond the S46 platform, dedicated communication channels between CSIRT teams and key service operators and digital service providers also play an important role. They serve for reporting incidents, exchanging information during their handling, as well as transmitting alerts and recommendations. Communication takes place through secure connections, using strong authentication and end-to-end encryption.
Information exchange mechanisms within sectoral cybersecurity teams are equally important. Cooperation platforms, regular meetings, and exercises enable key service operators to share experiences, analyze common challenges, and develop best practices. These teams work closely with relevant CSIRTs, ensuring two-way information flow between the technical and business levels.
NCS also actively participates in international threat information exchange, particularly within the CSIRT network and MISP platform at the EU level. This enables rapid acquisition of data about new threats detected by foreign partners, as well as sharing own analyses and indicators of compromise. This exchange takes place based on standardized data formats (e.g., STIX, TAXII) and trusted communication channels.
An important aspect of all these mechanisms is ensuring confidentiality, integrity, and availability of exchanged information. NCS applies a range of technical and organizational measures here, such as strong encryption, secure transmission protocols, role-based access control mechanisms, or regular security audits. Entities participating in the exchange must also meet rigorous requirements regarding protection of processed data.
Effective threat information exchange is not just a matter of tools, but above all of trust and a culture of cooperation. NCS actively promotes the idea of “sharing is caring,” emphasizing that in cybersecurity “we rise or fall together.” Regular meetings, workshops, and exercises serve to build relationships and understanding between different stakeholders, often with very different perspectives and priorities.
Thanks to these efforts, the National Cybersecurity System is becoming a true, tightly connected network, where information is a key resource and cooperation - a natural reflex. This is the foundation not only for effective incident response but above all for proactive building of cyber resilience of key economic and state sectors.
How Does NCS Conduct Exercises and Simulations of Cyberattacks on Critical Infrastructure?
Regular exercises and simulations are a key element of building readiness and resilience of the National Cybersecurity System against cyberattacks. They enable testing and improving incident response procedures, identifying weaknesses and areas requiring improvement, and building awareness and competencies among employees. NCS conducts a range of different exercises, adapted to the needs and specifics of individual critical infrastructure sectors.
The basic type are tabletop exercises, conducted in a virtual environment. Scenarios are developed by NCS experts in cooperation with key service operators and reflect realistic threats and attack vectors. Participants, divided into teams corresponding to their real roles (e.g., IT team, communication team, management), must react to a simulated incident according to applicable procedures. These exercises enable testing the effectiveness of existing plans, identifying gaps, and developing improvements.
A more advanced form is Red Team/Blue Team exercises. The “Red” team (composed of ethical hackers) conducts a controlled attack on the organization’s real systems, using techniques used by real criminals. The “Blue” team (defenders) must detect, stop, and neutralize the attack while maintaining continuity of key services. This type of exercise provides the most realistic picture of organizational readiness and often reveals vulnerabilities that escape traditional security audits.
NCS also organizes sectoral exercises, engaging many key service operators from a given industry. Wide-scale disruption scenarios are simulated, requiring cooperation and coordination between different entities. These exercises test not only technical response capabilities but also the effectiveness of communication, information exchange, and decision-making at the sector level. Conclusions serve to develop common standards, protocols, and cooperation mechanisms in case of a real crisis.
At the national level, NCS conducts cyclical interdisciplinary exercises, with the participation of all key stakeholders - from critical infrastructure operators, through public administration, to rescue and order services. Strategically significant scenarios are simulated, such as a coordinated attack on the national energy system or disruption of the election process. These exercises serve to improve national crisis management procedures, identify dependencies between sectors, and build trust between different actors.
NCS also actively participates in international cybersecurity exercises, such as Cyber Europe (coordinated by ENISA) or Locked Shields (organized by NATO CCD COE). They enable testing response capabilities to cross-border incidents, practicing cooperation with foreign partners, and exchanging best practices. Participation in these exercises also builds Poland’s prestige and credibility as a regional cybersecurity leader.
Regardless of scale and type, all NCS exercises are carefully planned, executed, and summarized. Scenarios are developed based on current threat analysis and trends in cybercrime. Exercise progress is monitored and documented, and at the end a detailed report with conclusions and recommendations is prepared. Results are discussed with participants and serve to improve existing procedures, identify training needs, or plan security investments.
Exercises and simulations are an investment in readiness and resilience that pays off at the moment of a real crisis. Thanks to regular training, NCS entities are better prepared for rapid and effective incident response, minimizing potential damage and ensuring continuity of key services. In an era when cyberattacks are becoming increasingly sophisticated and destructive, such readiness is no longer an option but a strategic necessity.
