The organization needs a structured plan for moving from legacy network communication protocols to modern, secure alternatives. This helps reduce long-term security risks while ensuring operational stability during the transition.

• Identify network communication protocols currently in use and assess which of them are outdated or no longer considered secure.
• Define target protocols that reflect current best practices for security, interoperability and performance.
• Develop an implementation plan that describes how the transition will take place in a secure, appropriate and gradual manner, taking operational dependencies into account.
• Establish measures to accelerate the transition where feasible, such as prioritising high-risk systems, setting deprecation timelines or aligning upgrades with planned system changes.
• Review and update the transition plan as technologies, risks or operational requirements evolve.

This planned approach supports a controlled migration to modern network protocols while maintaining service continuity and reducing exposure to protocol-level vulnerabilities.
