Security in isolated networks with OPSWAT

Isolated networks, also known as operational networks or industrial networks, are key infrastructure for many organizations operating in key sectors. These include energy, transportation, manufacturing and utilities. These highly protected network environments are separated from the public Internet and other corporate networks. This is done to ensure maximum security and continuity of critical systems. However, with the increasing complexity of cyber security threats, maintaining the integrity of isolated networks is becoming more challenging. Against this backdrop, OPSWAT’s comprehensive security solution offers unparalleled security. They enable secure data exchange and collaboration between isolated networks and external environments.

Key Features of Insulated Networks

Isolated networks play a key role in maintaining the business continuity and security of many key industrial and infrastructure operations. Their main features include:

• Separation from the public Internet: These networks are completely isolated from the Internet and other corporate networks. To minimize the risk of cyber attacks and unauthorized access.
• Restricted connectivity: access to the isolated network is strictly controlled and allowed only to authorized personnel and systems.
• Critical operating systems: These networks host industrial control systems (ICS), supervisory control and supervision systems (SCADA) and other critical operational applications responsible for monitoring and controlling industrial processes.
• Compliance requirements: Due to the critical nature of these environments, they are subject to strict regulations and safety standards, such as IEC 62443 and NERC CIP.

Security Challenges of Isolated Networks

Despite their physical isolation, these networks are not immune to cyber security threats. Key security challenges include:

• Advanced persistent threat (APT) attacks: Highly motivated and specialized hackers can use complex techniques such as social engineering and supply chain attacks to gain access to isolated networks.
• Insider threats: Unknowing or malicious insiders may inadvertently or intentionally introduce malware or disclose confidential information.
• Outdated systems: Many isolated networks use older operating systems and applications. They are no longer supported by vendors and may contain security vulnerabilities.
• Limited visibility: Monitoring and detecting threats in isolated networks can be difficult due to limited connectivity and lack of security tools.

Benefits of Implementing the OPSWAT Solution

Implementing a comprehensive OPSWAT security solution for isolated networks brings a number of benefits, including:

• Enhanced security: Advanced file and content analysis techniques provide effective protection against known and unknown threats. These include viruses, worms, Trojan horses and spyware.
• Regulatory Compliance: The OPSWAT solution helps organizations meet stringent safety and compliance requirements such as IEC 62443 and NERC CIP.
• Secure collaboration: Secure exchange of data and files between isolated networks and external environments enables effective collaboration without compromising security.
• Business Continuity: In fact, with effective protection against threats, the OPSWAT solution helps maintain business continuity of critical operating systems and industrial processes.
• Centralized control: centralized management and monitoring of all aspects of isolated network security provides better visibility and control.

OPSWAT Solution Use Cases.

OPSWAT’s security solution for isolated networks is used in a number of key sectors, including:

Energetics

Isolated grids play a key role in monitoring and controlling power generation, transmission and distribution systems. The OPSWAT solution ensures that these critical systems are protected from cyber attacks and enable secure collaboration with suppliers, partners and other third parties.

Manufacturing Industry

In manufacturing environments, isolated networks control industrial automation systems, production lines and manufacturing processes. The OPSWAT solution protects these systems from threats. At the same time, they enable secure exchange of data and files with suppliers, partners and other third parties.

Transport

Transportation systems such as railroads, airports and traffic control systems rely on isolated networks to monitor and control critical infrastructure. The OPSWAT solution ensures that these systems are protected from cyber attacks and enable secure collaboration with others in the supply chain.

Municipal Services

In addition, isolated networks play a key role in monitoring and controlling water supply systems, wastewater treatment plants and other municipal services. The OPSWAT solution protects these critical systems from threats and enables secure collaboration with suppliers, partners and other external parties.
