Technical Brief: Strengthening OT/ICS Cybersecurity in 2024 and Beyond
Introduction The cybersecurity landscape for Operational Technology (OT) and Industrial Control Systems (ICS) grew increasingly complex in 2024, marked by rising geopolitical tensions and a heightened awareness among adversaries. These adversaries view OT/ICS environments as potential attack vectors for disruption. As a result, organizations face escalating pressure to improve the visibility and resilience of their OT/ICS networks. This brief outlines key trends, threats, and actionable strategies to bolster your OT/ICS cybersecurity posture.
Key Trends and Threats in 2024
- Lowering Barrier to Entry: Adversaries find it easier to target OT/ICS.
- Growing Awareness: OT/ICS is now seen as an effective attack vector by a wider range of adversaries.
- Basic Techniques are Effective: Simple methods, like manipulating internet-exposed HMIs, can cause significant disruptions.
- Ransomware Targeting Manufacturing: Manufacturing environments are heavily targeted due to the immediate pressure of downtime. In 2024, 50% of ransomware targeted manufacturing.
- Hacktivist Activity: Hacktivists increasingly target OT for disruptive amplification of their messages.
- Living off the Land (LOTL): Threat groups such as VOLTZITE utilize tools already present on compromised systems.
The Tractor Tech Tug-of-War: Farmers, Manufacturers, and the Right to Repair
Introduction Modern agriculture is increasingly reliant on advanced technology. From GPS-guided autosteering to sophisticated onboard computers, today’s farm equipment is a far cry from the tractors of the past. This technological revolution, however, has sparked a significant conflict between farmers and manufacturers over the right to repair. Farmers are finding

Essential Cybersecurity Strategies
To defend against these evolving threats, organizations must implement key strategies:
- Implement the SANS ICS 5 Critical Controls: These remain the best defense.
- Focus on the Basics: Prioritize fundamental security measures.
- Enhance Network Security Monitoring: Employ ICS protocol-aware network visibility for quick compromise scoping and root cause analysis.
- Prioritize Vulnerability Management: Identify and address critical vulnerabilities. Use the "Now, Next, Never" framework to prioritize vulnerabilities based on their impact on operations, exploitability, and available mitigations.
- Develop and Update Incident Response Plans: Ensure plans address responses to incidents like ransomware or PLC logic modification.
- Establish a Defensible Architecture: Conduct annual attack surface analysis and secure network gateways (VPN, RDP, SSH).
- Increase Visibility and Monitoring: Implement OT-aware monitoring solutions to detect subtle adversary movements.
- Secure Remote Access: Scrutinize ad hoc access points with increased logging, alerting, and multi-factor authentication.
- Adopt Risk-Based Vulnerability Management: Focus on real-world threats and verify CVE accuracy, prioritizing those causing loss of view or control.
- Restrict access to engineering ports on PLCs with fieldbus communications features and to fieldbus couplers and protocol translators.
- Change default passwords on IoT equipment, restrict access to device management interfaces, and monitor for exploitation.
Specific Actions to Consider
- Fieldbus Equipment: Restrict access to engineering ports on PLCs with fieldbus communication features.
- IoT Equipment: Change default passwords, restrict access to device management interfaces, and monitor for exploitation. Have a plan if these systems fail.
- Third-Party Risks: Implement a Software Bill of Materials (SBOM) to list all software versions and add-on components.
- DLL Hijacking: Hunt for DLL hijacking vulnerabilities and implement mitigations.
- Modbus/TCP: If using Modbus/TCP, assess the implementation of the SANS ICS 5 Critical Controls.
- SSH: Identify assets with SSH exposed to the internet and conceal access behind a VPN. Audit SSH keys and ensure strong passwords.
- VNC: Restrict access to VNC servers, especially on ports TCP/5800, TCP/5900, and TCP/5901. If remote access is needed, use a VPN and change default credentials.
