CSPM (Cloud Security Posture Management)

Cloud Security Posture Management is a category of tooling that continuously scans cloud accounts for misconfigurations, excessive permissions, and policy violations against benchmarks such as CIS. As 5G core and OSS workloads migrate into hyperscaler clouds, CSPM becomes a baseline control alongside cloud workload protection and identity governance.

CSPM in context

The mobile core carries subscriber sessions, mobility and policy. In 4G it is the EPC (MME, HSS, S/PGW); in 5G it is the Service-Based Architecture with AMF, SMF, UPF, AUSF, UDM and the NRF.

Subscriber identifiers (IMSI, SUPI, MSISDN, IMEI) anchor authentication, charging and lawful interception. Any protocol that leaks a permanent identifier is treated as a privacy defect, which is why 5G introduced SUCI concealment on the air interface.

To place CSPM in the wider telecom-security picture, review Confidentiality, Cryptography, EIR, Encryption, FDD and GMSC — each entry cross-references back to this page so you can walk the topic in either direction.
