Why secure OT protocols still struggle to catch on

Help Net Security

February 13, 2026 at 9:02 AM

Overview

Industrial control systems are still relying on outdated communication protocols that prioritize reliability over security features like authentication and data integrity. This leaves networks vulnerable, allowing attackers to impersonate devices, send unauthorized commands, or alter messages without being detected. A new guidance document from the Cybersecurity and Infrastructure Security Agency (CISA) explains the reasons behind the slow adoption of more secure versions of these industrial protocols. Despite their availability, many organizations are hesitant to implement them, which raises serious concerns about the security of critical infrastructure. The continued use of legacy systems could lead to significant risks for industries that depend on these technologies.

Key Takeaways

Affected Systems: Industrial control systems, legacy communication protocols
Action Required: Organizations should consider upgrading to secure versions of industrial protocols and implement stronger authentication measures.
Timeline: Newly disclosed

Original Article Summary

Industrial control system networks continue to run on legacy communication protocols that were built for reliability and uptime, not authentication or data integrity. In many environments, malicious actors with access to the OT network can impersonate devices, issue unauthenticated commands, or modify messages in transit without detection. A new guidance document from the Cybersecurity and Infrastructure Security Agency (CISA) explains why secure versions of common industrial protocols remain underused, even though they have existed since … More → The post Why secure OT protocols still struggle to catch on appeared first on Help Net Security.
