Slice Security

Security mechanisms protecting individual network slices in 5G networks. Includes slice-specific authentication, authorization, encryption, traffic isolation, and protection against cross-slice attacks. Each slice can have differentiated security policies based on service requirements.

Slice Security in context

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.

Telecom threats range from opportunistic SMS phishing and SIM swap to nation-state grade location tracking. The common thread is that most attacks exploit the inherited trust model of legacy signaling protocols.

To place Slice Security in the wider telecom-security picture, review EDR, A5/0, ASN, BGP Hijacking, CASB and Cipher Downgrade Attack — each entry cross-references back to this page so you can walk the topic in either direction.
