Understanding End-of-Support:
End-of-Support Status: When a vendor declares a device as end-of-support, it means the device will no longer receive updates, patches, or technical support. This poses a security risk as new vulnerabilities will not be addressed.
Risks of Keeping an End-of-Support Device:
Security Vulnerabilities: Without updates, the switch becomes susceptible to new security threats.
Compliance Issues: Many regulatory frameworks require that critical infrastructure be maintained with supported and secure hardware.
Best Next Step - Replacement:
Decommission and Replace: The most secure approach is to replace the end-of-support switch with a new, supported model. This ensures the infrastructure remains secure and compliant with current standards.
Planning and Execution: Plan for the replacement by evaluating the network's needs, selecting a suitable replacement switch, and scheduling downtime for the hardware swap.
Comparison with Other Options:
Apply the Latest Patches: While helpful, this does not address future vulnerabilities since no further patches will be provided.
Ensure the Current Firmware Has No Issues: This is only a temporary measure and does not mitigate future risks.
Isolate the Switch from the Network: Isolating the switch may disrupt network operations and is not a viable long-term solution.
