Securing Operational Technology in 2024

A Comprehensive Guide for SMBs

Hello, I'm Johnathan Lightfoot, President of Symbiont, Inc. Small and medium-sized businesses (SMBs) are increasingly relying on operational technology (OT) to streamline their processes and increase efficiency. However, this comes with a range of cybersecurity challenges. As we step into 2024, here are some key strategies and best practices for securing your operational technology. 

Security-First Culture

Embed cybersecurity awareness across all levels of your organization. Training should include recognizing phishing scams, using strong passwords, and understanding the importance of software updates. 

Network Segmentation

Separate your OT network from the IT network to contain potential breaches and make it more difficult for attackers to move laterally across your systems. 

Zero-Trust Architecture

Implement a zero-trust model for your OT network, which requires strict identity verification for every person and device trying to access your system, irrespective of whether they are sitting within or outside of your network. 

Regular Audits

Conduct regular security audits specifically targeted at your OT assets. These audits can identify vulnerabilities that may be unique to the specialized software and hardware used in OT. 

Endpoint Protection

All devices connected to your OT network should have endpoint security software to monitor and block malicious activities. 

Real-time Monitoring and Analytics

Utilize AI-based security tools for real-time monitoring of your OT network. These tools can detect unusual patterns and potential threats before they can do any damage. 

Multi-Factor Authentication (MFA)

Implement MFA across the board, especially for accessing sensitive or critical OT systems. This extra layer of security can keep attackers at bay even if they gain access to a password. 

Data Backups and Recovery Plans

Ensure that you have robust data backup procedures and a well-documented recovery plan in the event of a cyberattack like ransomware.
