Operating system security for CLM stations

RHEL patches

For customer-sourced and manually deployed RHEL OS instances, Nokia supports customers applying RHEL patches provided by Red Hat which include security fixes as well as functional fixes. If a patch is found to be incompatible with the CLM, the patch may need to be removed until a solution to the incompatibility is provided by Red Hat or Nokia. See the CLM Release Notice for up-to-date information about the recommended RHEL maintenance update and patch levels.

For customers using the Nokia-provided RHEL OS images, only the RHEL OS update provided by Nokia can be applied.

Platform hardening

Additional efforts to secure the system could impact CLM operation or future upgrades of the product. Customers must perform some level of basic testing to validate that additional platform hardening does not impact the operation of the CLM. The CLM Product Group makes no commitment to make the CLM compatible with a customer's hardening requirements.
