Critical Infrastructure Protection: Trust IAP for OT and ICS

Critical Infrastructure Protection: Trust IAP for OT and ICS

In the era of ubiquitous digitalization, where automated process control systems (APCS) and operational technologies (OT) are becoming increasingly interconnected, cybersecurity issues are of paramount importance. Insufficient protection of industrial networks can lead to serious consequences, including disruption of production processes, equipment failures, environmental disasters, and even threats to human life. That's why Trust Tech has developed Trust IAP (Industrial Access Platform) - a comprehensive solution designed to ensure the security of critical infrastructure.

IT and OT Network Segmentation: The Foundation of a Secure Infrastructure

Traditionally, IT (information technology) and OT (operational technology) networks in industrial enterprises were separated, which provided a certain level of security. However, with the introduction of Industry 4.0 technologies and the desire to optimize production processes, the boundaries between these networks are becoming increasingly blurred. The integration of IT and OT networks, while offering new opportunities for improving efficiency and flexibility, also creates new risks associated with cyber threats.

Trust IAP offers an effective solution for separating IT and OT networks, providing controlled and secure access between these networks. This is achieved through the use of the following mechanisms:

• Network microsegmentation: Trust IAP allows you to divide the network into small, isolated segments, which limits the spread of malicious code in the event of a compromise of one of the segments. Each segment has its own security policies that determine which devices and users can access it.
• Role-based access control (RBAC): Trust IAP uses a granular access control system that allows you to grant users only the rights and privileges that they need to perform their job duties. This reduces the risk of accidental or intentional damage to the system.
• Next-Generation Firewall (NGFW): The built-in NGFW in Trust IAP provides deep traffic analysis at the application layers, allowing you to identify and block complex cyber threats, such as targeted attacks and malware.
• Two-Factor Authentication (2FA): Trust IAP supports two-factor authentication for all users accessing OT systems. This significantly increases access security and reduces the risk of account compromise.

Benefits of IT and OT Network Segmentation with Trust IAP:

• Increased level of security by reducing the likelihood of cyber threats spreading between IT and OT networks.
• Simplified security management through centralized management of security policies for all network segments.
• Compliance with regulatory requirements in the field of cybersecurity of critical infrastructure.
• Reduced risk of production downtime caused by cyberattacks.

Secure Remote Repair and Equipment Diagnostics: Key to Operational Efficiency

In modern conditions, when qualified specialists may be located at a considerable distance from production sites, the possibility of remote repair and diagnostics of equipment becomes critical to maintaining the continuity of production processes. However, providing remote access to OT systems involves serious security risks, as attackers can use this access to penetrate the network and cause damage.

Trust IAP provides a secure solution for remote repair and diagnostics of equipment, which allows specialists to access OT systems from anywhere in the world without compromising network security. This is achieved through the use of the following technologies:

• Secure VPN tunnel: Trust IAP establishes a secure VPN tunnel between the remote user and the OT system, ensuring the confidentiality and integrity of the transmitted data.
• Principle of Least Privilege (PoLP): Remote users are granted only the rights and privileges that they need to perform a specific equipment repair or diagnostic task.
• Session Monitoring and Auditing: All remote access sessions to OT systems are carefully monitored and recorded for audit and security incident investigation purposes.
• Device Control: Trust IAP can control the types of devices from which remote access is allowed and check them for compliance with security policies.
• Integration with Identity and Access Management (IAM) systems: Provides centralized management of remote user accounts and access rights.

Benefits of Secure Remote Access with Trust IAP:

• Reduced equipment downtime due to prompt remote repair and diagnostics.
• Reduced travel costs for specialists to carry out repairs.
• Increased work efficiency by providing specialists with remote access to OT systems.
• Improved network security through controlled and secure remote access.

Preventing Physical Accidents through Cyber Protection: Ensuring the Safety of Production Processes

Cyber threats can not only damage information systems, but also lead to physical accidents at the production site. Attackers can use cyberattacks to manipulate OT systems, which can lead to equipment failure, disruption of technological processes, and even environmental disasters.

Trust IAP helps prevent physical accidents by providing reliable cyber protection for OT systems. This is achieved through the following measures:

• Anomaly Detection: Trust IAP uses machine learning algorithms to detect anomalous behavior in OT networks, which may indicate a cyberattack or equipment malfunction.
• Intrusion Detection and Prevention System (IDS/IPS): The built-in IDS/IPS in Trust IAP detects and blocks attempts to unauthorized access to OT systems.
• Vulnerability Management: Trust IAP helps identify and eliminate vulnerabilities in OT systems, reducing the risk of these vulnerabilities being exploited by attackers.
• Malware Protection: Trust IAP protects OT systems from malware that can be used for sabotage or espionage.
• Incident Response: Trust IAP provides tools for rapid and effective response to security incidents, minimizing damage from cyberattacks.
• OT Traffic Analysis: Trust IAP provides deep OT traffic analysis, identifying unusual communications that may indicate an attack.

Benefits of Preventing Physical Accidents with Trust IAP:

• Reduced risk of accidents at the production site caused by cyberattacks.
• Increased personnel safety by preventing dangerous situations.
• Environmental protection by preventing environmental disasters.
• Protecting company reputation by preventing the negative consequences of accidents.

Key Features of Trust IAP:

• Centralized Management: Trust IAP provides a single console for managing all aspects of OT system security.
• Scalability: Trust IAP can be deployed in enterprises of any size, from small production sites to large industrial complexes.
• Integration with Existing Systems: Trust IAP easily integrates with existing security and IT infrastructure management systems.
• Ease of Use: Trust IAP has an intuitive interface that allows you to quickly and easily configure security policies and manage the system.
• Automated Reporting: Trust IAP provides automated reports on the security status of OT systems, which allows you to quickly identify and resolve problems.

Trust IAP Architecture

Trust IAP can be deployed in various architectures, depending on the needs and requirements of a particular enterprise. The most common deployment options include:

• On-premise: Trust IAP is deployed on servers located in the enterprise infrastructure.
• Cloud-based: Trust IAP is deployed in a cloud infrastructure, which provides flexibility and scalability.
• Hybrid: Trust IAP is deployed as a combination of on-premise and cloud-based solutions, which allows you to use the advantages of both options.

Regardless of the chosen architecture, Trust IAP provides reliable protection for OT systems from cyber threats.

Compliance with Standards and Requirements

Trust IAP complies with international standards and requirements in the field of cybersecurity of critical infrastructure, such as:

• NIST Cybersecurity Framework: US National Cybersecurity Framework.
• IEC 62443: International standard for industrial network security.
• NERC CIP: North American Electric Reliability Corporation Critical Infrastructure Protection Standards.
• FZ-187: Federal Law of the Russian Federation "On the Security of Critical Information Infrastructure of the Russian Federation."

Compliance with these standards and requirements ensures that Trust IAP provides a high level of security for OT systems.

Conclusion

Trust IAP is a comprehensive and effective solution for protecting critical infrastructure from cyber threats. Thanks to its advanced technologies and features, Trust IAP allows enterprises in the manufacturing and energy sectors to ensure the security of their OT systems, prevent accidents, and protect their business from financial and reputational losses.
