name: CUO
full_form: Certificate Update Orchestrator
context: CUO performs the following actions in order to mitigate the risks of automated certificate management leading to service un-availability. - Monitoring of certificate expiry related alarms reported by network management systems - Monitors CA announcements for certificate revocations - CUO may subscribe to CA announcement notifications - Monitors CRL/OCSP data stores for certificate revocations - CUO may subscribe to notifications from applications that monitor changes / updates in CRL/OCSP data stores - Accept certificate update triggers from the operator or an automation related function. To ensure the proper management of the certificate updates for a large number of NFs, CUO may perform the following actions: - Stagger the certificate updates in time such that only a small amount of certificate updates is ongoing simultaneously, while ensuring the updates are done within the stipulated time, especially for those that are close to expiry. - Prioritize the certificate updates for those
