Neglected OT / ICS cyber security can have costly consequences

The convergence of information technology (IT) and operational technology (OT) combined with the emergence of the Industrial Internet of Things (IIoT) has revolutionised many industries such as manufacturing, energy and transport.

OT systems and networks were developed for isolated and controlled environments. Increasing connectivity significantly increases the attack surface.

Challenges for OT security

OT environments face unique challenges:

• Outdated systems: A lack of security makes systems vulnerable and outdated.
• Limited downtime: Limited options for patches, upgrades, operations and security.
• Lack of transparency: Limited inventory, monitoring and threat detection.
• Advanced threats: Targeted attacks, ransomware and supply chain attacks.
• Remote access and supply chain: Remote working and access by third parties harbour considerable risks.

The path to the future: proactive strategy and comprehensive security

As OT environments become increasingly connected, organisations need to complement industry best practices and take a comprehensive, multi-layered approach to cybersecurity.

              1. Segmentation: First line of defence

Segmentation forms the basis for building a secure OT environment and is extremely effective in containing the spread of potential threats.

              2. Threat defence: defence in depth 

Advanced threat defence mechanisms enable virtual patching and protect against malicious traffic, activity and zero-day threats.

              3. Security at device level: the turning point 

Check Point’s innovative, lightweight, software-based IoT Protect Nano agent represents a significant step forward by protecting the source of potential threats: The devices themselves.

While segmentation remains essential, investment in deep threat prevention and innovative solutions such as the Nano Agent will ensure that organisations secure their future.
