- Community Submitter Notes
- This technical reference guide details the methodologies required to defend enterprise identities against SIM swapping, telecommunications social engineering, and unauthorized eSIM provisioning in 2026. The analysis examines the structural vulnerabilities of SMS-based two-factor authentication (2FA) and SS7/cellular signaling interception. It provides systems administrators and security operations teams with an actionable roadmap for enforcing carrier-level port-out locks, establishing high-entropy telecommunications PINs, and migrating corporate user directories to phishing-resistant FIDO2/WebAuthn passkey architectures to prevent account takeover (ATO).
