Digital cellular telecommunications system (Phase 2+) (GSM); Universal Mobile Telecommunications System (UMTS); LTE; Study on security aspects of Public Warning System (PWS) (3GPP TR 33.969 version 15.0.0 Release 15)

Scope

The present document studies security features and mechanisms for protection against false Base Stations broadcasting
False Warning Notifications.
The default terminal behaviour is to accept all Warning Notifications even if their authenticity is unknown (i.e. no
security protection). The default terminal behaviour is therefore open to the presentation of false Warning Notifications
issued by false BSs even in countries without a Public Warning System (PWS) deployed.
Examples of false BS risks include, but are not limited to:
- False Warning Notifications to induce panic;
- Abuse of warning system broadcast channel to send advertising / spam.
