IT and OT Security

in the Industrial Sector

The industrial sector is particularly vulnerable to cyberattacks

The integration of IT and OT systems increases the attack surface.
Modern manufacturing facilities integrate business systems (ERP, MES) with production control systems (ICS/SCADA, PLC). This integration increases the risk of threats spreading from IT networks to production infrastructure.
Legacy industrial infrastructure (legacy OT)
In many manufacturing facilities, control systems designed decades ago are still in use. They were not built with cybersecurity in mind and often cannot be easily updated.
High pressure to maintain production continuity
A production line shutdown can result in significant financial losses in a very short time, making industrial companies particularly attractive targets for ransomware attacks.
A large number of industrial systems and devices
Industrial robots, PLCs, automation systems, IoT sensors, and control devices create a complex technological environment that is often difficult to fully monitor.
Intellectual property and technological data

Industrial companies possess vast amounts of valuable technological data, such as:

  • product designs and technical documentation
  • recipes and production parameters
  • manufacturing know-how
  • data related to quality and production efficiency

This data is particularly attractive for industrial espionage, intellectual property theft, and competitive exploitation.

Complex production environments

Industrial facilities often include:

  • multiple production lines
  • distributed plants and factories
  • integrations with logistics and warehouse systems
  • production and quality monitoring systems

Lack of full visibility into network traffic in such environments increases the risk that security incidents may go undetected for extended periods.

Supply chain effect

Production relies on complex supply chains and collaboration with multiple partners, including:

  • component suppliers
  • automation system integrators
  • service providers
  • technology vendors

Cybercriminals often exploit less secure partners as an entry point into a manufacturer’s infrastructure.

Remote access to industrial infrastructure

Modern manufacturing facilities rely on:

  • remote servicing of automation systems
  • access for integrators and technology vendors
  • cloud-based production monitoring systems

If not properly secured, such access can become an easy pathway for attackers to take control of production systems.

The impact of a successful attack may include:

  • production downtime
  • manipulation of technological processes
  • damage to infrastructure
  • significant financial losses.

Key technologies and processes supporting IT and OT security in industry

Endpoint Detection and Response solutions monitor activity on workstations and servers, detecting malware, privilege escalation attempts, and unusual user behavior. They provide a critical layer of protection against ransomware and other advanced threats.

Network Detection and Response solutions provide full visibility into network communications, including in OT environments where installing agents is often not possible. They enable the detection of anomalies, lateral movement, and suspicious connections between systems that may indicate an ongoing attack.

Dividing infrastructure into security zones (e.g., IT and OT) limits the spread of threats. The use of next-generation firewalls and microsegmentation enables control over traffic between systems and minimizes the risk of unauthorized access to critical assets.

Privileged Access Management secures access to critical systems by controlling and monitoring privileged accounts. It reduces the risk of misuse, account compromise, and unauthorized actions in the production environment.

DDoS attacks can lead to the unavailability of critical systems supporting production, such as ERP, MES, or remote access systems, directly resulting in operational disruptions and downtime. Anti-DDoS solutions analyze network traffic and filter malicious requests intended to overload infrastructure, ensuring system availability and the stability of production processes.

The SOC (Security Operations Center) service provides 24/7 monitoring of the environment. A team of experienced analysts uses EDR, NDR, and SIEM tools to analyze data and respond to potential threats.

Their responsibilities include:

  • monitoring and detecting incidents,
  • analyzing and classifying threats,
  • isolating threats and limiting the impact of attacks,
  • restoring system operations,
  • reporting and post-incident analysis.

A process of regularly identifying and remediating security vulnerabilities in systems and applications.

It includes:

  • vulnerability scanning,
  • analysis of results,
  • prioritization of fixes,
  • implementation of updates and patches.

A process of collecting and analyzing information about new attack techniques and emerging threats.

It enables organizations to:

  • identify new phishing campaigns and malware,
  • update detection rules,
  • prepare for new attack vectors.

Proactive identification of threats in the IT environment that have not been detected by standard security systems.

Analysts analyze telemetry data and formulate hypotheses about potential attacks.

A process of developing and optimizing threat detection mechanisms. It includes:

  • creating detection rules,
  • adapting security systems to the specifics of the environment,
  • reducing the number of false positives.

The NIS2 Directive, which applies to the industrial sector, requires organizations to ensure the security of their supply chains.

The process includes:

  • assessing the security of suppliers,
  • controlling API integrations,
  • monitoring risks associated with external services.

A process that ensures the rapid restoration of system operations after a failure or cyberattack.

It includes:

  • backups,
  • data recovery plans,
  • testing of disaster recovery procedures.

Separating OT environments from the internet and corporate IT networks aims to limit the spread of threats between environments and reduce the risk that an incident in the office (IT) part of the organization will impact production control systems.

The process includes:

  • segmentation of IT and OT networks,
  • control of communication between zones,
  • restricting remote access to production systems,
  • implementing firewalls and access policies,
  • monitoring traffic between environments.

This enables organizations to better protect production systems against ransomware, lateral movement, and other threats that often enter OT environments from IT networks or the internet.

FAQs

Yes – in many cases, the industrial sector is subject to the NIS2 Directive. The new regulations cover, among others, companies in manufacturing (e.g., chemical, food, machinery, and energy industries), which—depending on their size and importance to the economy—may be classified as essential or important entities.

In practice, this means an obligation to implement risk management measures, monitor security, detect and report incidents, and ensure business continuity. NIS2 also extends responsibility to the supply chain, requiring organizations to assess the security of partners and suppliers.

Preparing a manufacturing facility to meet NIS2 requirements requires a comprehensive approach covering both IT and OT environments. The first step is to conduct a risk assessment and identify critical systems and production processes. Based on this, the organization should implement appropriate security measures, including network segmentation, monitoring (SOC), threat detection systems (EDR/NDR), and vulnerability management.

It is also essential to establish incident response and reporting procedures, as well as ensure business continuity (backups, disaster recovery). NIS2 further requires securing the supply chain and providing regular employee training.

Additionally, organizations should conduct regular security audits—at least every three years for essential entities—to verify the effectiveness of implemented measures and compliance with the directive.

In IT environments, the key priorities are ensuring data confidentiality, system integrity, and service availability (the CIA model). In OT environments—i.e., production control systems (ICS/SCADA)—the primary focus is on operational continuity and the safety of physical processes.

The differences also extend to technologies. IT environments can be effectively protected using solutions like EDR, which are installed directly on endpoints. In OT environments, installing EDR is often not feasible due to legacy systems, technological limitations, or the risk of disrupting production. In such cases, NDR solutions play a crucial role by complementing endpoint protection with network traffic analysis, enabling threat detection where agent-based approaches cannot be applied.

Yes – professional penetration tests are designed so as not to impact system availability. Key safeguards include:

  • Clearly defined scope – before testing begins, it is agreed which systems will be actively tested and which are excluded. In industrial environments (OT/SCADA), critical control systems may be subject only to passive analysis.
  • Manual approach – an experienced tester controls every step and can immediately stop the activity if needed.
  • Test environments – where the risk is too high, testing is conducted in a dedicated test environment or a replica of the production configuration. Continuous communication with the client’s IT team – in case of any unexpected effects, testing is immediately halted.

With an experienced team and clearly defined rules of engagement, the risk to production continuity is very low.
