Threat-Led Assessment

A threat-led assessment evaluates an organisation's defences against the specific tactics, techniques, and procedures of relevant threat actors, rather than against a generic checklist. Examples include the European Central Bank's TIBER-EU framework for the financial sector and equivalent telecom-sector exercises; results feed into prioritised hardening and SOC tuning.

Threat-Led Assessment 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 Threat-Led Assessment in the wider telecom-security picture, review A5/0, ASN, BGP Hijacking, CASB, Cipher Downgrade Attack and CLI Spoofing — each entry cross-references back to this page so you can walk the topic in either direction.
