Industrial Cyber Security and Operational Resilience – Protecting Industry and Critical Infrastructure

OT Security Technologies and Professional Services for Secure Industrial Networks

The convergence of IT and OT (Operational Technology) is creating a new technological world: the Industrial Internet of Things (IIoT). IT and OT managers are faced with the challenge of correctly and safely addressing the opportunities and risks of digitalisation and networking.

OT Security plays a crucial role in this. Effective OT Security measures not only ensure protection against cyber threats, but also strengthen operational resilience. Companies can adapt to changing conditions, overcome disruptions and ensure continuous business operations. With OT Security, a no-disruption, never-down mentality is possible to ensure smooth and secure operations.

OT Security enables secure and resilient digitalisation, automation and IT-OT convergence

With the digitalisation and automation of critical infrastructure and industrial product environments, the points of attack have multiplied. Random or targeted attacks from IT, security vulnerabilities in software and hardware, attacks from the supply chain, insider threats, misconduct, industrial espionage and infrastructure failures demand adapted protection mechanisms.

Network virtualisation and holistic risk management

Transparency is the basis for secure industrial networks, infrastructure and production. Only complete knowledge of all assets and network communication enables the efficient selection of suitable security strategies, appropriate risk management and the early detection of threats and anomalies.

Real-time monitoring and proactive threat detection

By analysing network and telemetry data from various systems, devices and protocols in real time, new technologies such as Nozomi Networks’ passive OT Security Sensors help to generate valuable information and create new insights for decision-making without affecting ongoing operations. Pre-processed and aggregated data provides you with relevant information on the status of current cyber hygiene and the current threat situation. Using Threat Intelligence, threat data and behavioural patterns can be put into a broader context and security-relevant operations can be understood and prevented at an early stage

Advanced Threat Detection and Defense
  • Overview of components and systems
  • Firmware versions, serial numbers and network configuration
  • Coupling to ERP (Enterprise Resource Planning) and CMDB (Configuration Management Database)
  • Transparency about communication relationships
  • Insights into network problems, bottlenecks, operational peculiarities
  • Weaknesses benchmarking
  • Guarantee, availability and reliability
  • Detection of cyber-hygiene deviations such as misconfigurations
  • Alerting of dedicated cyber threats
  • Triggering of automated interventions in case of serious attacks (defence)

„The biggest mental challenge for IT and OT practitioners is not only a rethinking,
but a new way of thinking about the entire task area.

Interdisciplinary teams including new technical equipment are needed
to jointly create a secure Industrial IoT Infrastructure in the companies. “

Cyber security and network visualisation for industrial production and critical infrastructure

The increasing threat of ransomware, supply chain attacks and phishing attacks pose a serious threat to your IT systems. Vulnerable OT/IoT devices are also gateways for potential attacks. To effectively protect your business, you need an up-to-date view of assets, protocols, network traffic and vulnerabilities in critical infrastructure and production.

Guardian™ by Nozomi Networks provides visibility of production networks and early detection of cyber threats, risks and anomalies. Intelligent notifications and the ability to monitor process variables enable a targeted response to security incidents. In addition, Nozomi Networks Threat Intelligence™ provides global information and insights that are also of interest to IT, such as real-time detection of malware or vulnerabilities.

In many OT security projects, the essential question of responsibility within the company arises. Who is responsible for OT security in production and critical infrastructure, especially the CISO and IT security experts? Often the role is delegated by the operations manager. IKARUS supports you in improving your IT/OT security as well as in a Proof of Value and offers intelligent system integration into your existing Security Operations Centre. Our customers particularly appreciate our advisory calls and health checks.
