Industrial and Operational Technology (OT) Cybersecurity Services

Operational technology and industrial IT cybersecurity consulting | TÜV Rheinland

Focus on productivity and security: Take advantage of our expertise in Operational Technology cyber security.

In the era of Industry 4.0 and increased networking, IT and OT (Operational Technology) must interact consistently. As growing networks are on the rise, this means increasing OT complexity and larger attack surfaces. Today, the question is no longer whether you will be attacked, but rather when.

Take advantage of our many years of industrial know-hows with combined cybersecurity expertise to holistically secure your operating technology and thus meet the increasing requirements for industrial cybersecurity, regulatory requirements, and functional security.

Eight reasons why OT security is essential:

IT/OT convergence and complexity
Resilience
×

IT/OT convergence and complexity

The increase of interconnection of non-homogeneous systems, applications, and platforms, along with the increasing complexity of Operational Technology is steadily increasing the attack surface.

×

Resilience

Cyber-related problems that cause system failures and unwanted downtime result in significant costs.

Protecting human life
Maintaining reputation
×

Protecting human life

In the worst-case scenario, people are put at risk by malfunctions or attacks on Safety Controllers and Critical Infrastructures (CRITIS).

×

Maintaining reputation

If there is data loss, system shutdown or security failure, a reputation loss is inevitable.

Data theft
Regulatory obligations
×

Data theft

Production facilities are attractive targets for extracting data and stealing intellectual property and trade secrets.

×

Regulatory obligations

The Industrial Safety Regulation (BetrSichV), amendment to the NIS Directive (NIS2), EU Cyber Resilience Act or the IT Security Act 2.0 (IT-SiG 2.0): More organizations are required to comply with regulatory standards.

Skills shortage
Focus on Critical Infrastructures
×

Skills shortage

While the demand for industrial cybersecurity is increasing, responsibilities are not clear and specialized professionals are scarce - without external support, effective cyber defense will be almost impossible.

×

Focus on Critical Infrastructures

As critical infrastructures are worthwhile targets, attacks are increasing particularly strongly here - the healthcare and energy supply sectors are being targeted heavily.

With strategies, policies, and processes, we ensure that your operational technology is protected and meets regulatory requirements and compliance rules. This includes protecting OT systems against threats from external or internal attackers, monitoring for vulnerabilities and anomalies, and implementing contingency plans and responses.

If you know which devices and systems are part of your network and how they interact with each other, you can implement effective security measures. Therefore, we create the basis to identify, visualize and manage all devices, technologies, and activities in your operational network.

By analyzing the impact of a security incident on your business and production processes, potential risks and threats can be best identified. In this way, BIA helps improve your OT security strategies and develop recovery and business continuity plans.

In order to take appropriate risk mitigation measures, we identify and assess the risks of potential security incidents. In doing so, we analyze hardware, software, and network architecture of your operating technology. The result is a complete assessment of existing security measures and protocols, detailing gaps, or weaknesses.

With measures such as access controls, data encryption, network traffic monitoring and anomaly detection, your OT is effectively protected from threats. Implementing firewall, intrusion detection/prevention systems and network segmentation also help monitor network traffic, block unauthorized access, and limit the impact of security incidents.

Business continuity management (BCM) and data recovery (DR) aim to restore critical business and production processes as well as data as quickly as possible in the event of a security incident. This includes risk analysis, business impact analysis, contingency planning, testing and exercises. The result is increased resilience in the context of OT security incidents.

The Security Operations Center (SOC) is the central point for monitoring, analyzing and responding to security incidents. Highly skilled SOC analysts use advanced tools and technologies to monitor and improve the security of industrial assets and networks and to meet compliance requirements.

Full service for holistic industrial safety.

We know your challenges and deliver the right solutions: From identifying risks and requirements to implementing security measures. We are at your side in every phase of your OT security. You benefit from proven processes and solution-oriented technologies to effectively manage risks, detect attacks early and proactively defend against them.

What is OT Security?

OT Security refers to the protection of operational technology and industrial systems used to monitor and control processes in infrastructures such as energy supply, transportation, healthcare, production or water and wastewater infrastructure. Threats can range from physical manipulation of equipment to cyber-attacks and data manipulation.

Does my company need OT security services?

If you operate in an area where critical infrastructures (CRITIS) are operated, it is important and even mandatory to secure OT. Not only does this prevent disruptions, interruptions, or attacks on the infrastructure, but it can also protect human lives in the event of an emergency. And when you consider what an unintentional production stoppage can cost, industrial manufacturing plants should also take OT security measures.

What does IT/OT convergence mean?

IT/OT convergence refers to the process in which the traditionally separate areas of information technology (IT) and operational technology (OT) are increasingly being brought together. This is due to increasing digitization, IT and OT systems are being integrated more frequently to improve efficiency and reduce costs. In addition to all the advantages, however, this also increases the attack surface, which means that operating technology is increasingly targeted by cybercriminals.

What is an OT SOC?

An OT SOC (Operational Technology Security Operations Center) is a control center that monitors and analyzes security threats in operational technology around the clock. Specially trained professionals here use advanced security technologies and processes to detect, prevent and respond to threats.

What does the lEC 62443 series of standards address?

The IEC 62443 series of standards (also known as ISA/IEC 62443) is an international series of standards that addresses the cybersecurity of industrial automation and control systems (IACS). It defines a comprehensive security architecture and processes for IACS and provides requirements, guidelines, and recommendations for various aspects of IACS cybersecurity.

What is the NIST Cyber Security Framework?

The NIST Cyber Security Framework (CSF) is designed to improve cybersecurity in businesses and organizations. It was developed by the U.S. National Institute of Standards and Technology (NIST) and published in 2014. The core of the NIST CSF defines five main functions that should be considered when implementing cybersecurity. These are identification, protection, detection, response, and recovery.

How do vulnerability and risk management work?

Vulnerability Management (VM) refers to a process that identifies an organization's vulnerabilities (Common Vulnerabilities and Exposures, CVEs) that could be exploited by attackers to compromise individual assets. Thus, vulnerability management follows the motto: Only those who know their weaknesses can protect themselves effectively.

Risk management, on the other hand, is used to understand and manage potential risks. Thus, a first step is to understand the risk potential of the affected assets and systems in order to identify potential vulnerabilities and threats and to implement appropriate measures.

What is the Purdue Reference Model?

The Purdue Reference Model is a conceptual model used to classify process control and automation systems. It was developed by Purdue University in the 1990s and breaks down process control and automation systems into seven different levels, each with different functions. Connected devices and systems are assigned to the levels, while technical protection measures are implemented at the transitions between the areas.
