OSS (Operations Support System)
The software systems and processes supporting network operations in telecommunications including network management, service provisioning, network inventory, fault management, configuration management, and performance monitoring. OSS systems interface with BSS (Business Support Systems) and network elements to enable service delivery and network operations.

OSS in context
OSS/BSS platforms (provisioning, charging, mediation, order management) hold the highest-value subscriber and revenue data on the operator side. They are heavily targeted for fraud and insider abuse and are increasingly in scope for regulatory obligations like NIS2 and the UK Telecoms Security Act.
To place OSS in the wider telecom-security picture, review Operating System (OS), Order Management, 3GPP, BSS, Charging System and Control Plane Security.
