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) 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.

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

To place OASIS in the wider telecom-security picture, review Key Management, X.500, SM-DP+, GBA, 2G and 3G — each entry cross-references back to this page so you can walk the topic in either direction.
