OASIS (Organization for the Advancement of Structured Information Standards)

OASIS is a non-profit international consortium that develops open standards for structured information, including SAML for federated identity, XACML for access control policy, WS-Security, MQTT for IoT messaging, and many others. OASIS standards underpin parts of identity, IoT, and document-exchange ecosystems used by telecom operators and their customers.

OASIS in context

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

Security controls in telecom span signaling firewalls (SS7/Diameter/GTP screening at the network edge), transport encryption (IPsec, TLS, PRINS), identity and access on OSS/BSS, and monitoring at both the packet and log level. Controls are audited against GSMA FS.11/FS.19/FS.20/FS.36 and, in Europe, NIS2 sectoral rules.

To place OASIS in the wider telecom-security picture, review X.500, NIST, Key Management, OCS, SCADA and SECA.
