Telecom Security
Telecom security and network identity
Telecom security protects networks, signalling, and subscriber identity. It also supplies population-scale possession signals for authentication.

Treat subscriber identity as part of the trust chain, with its own threats and controls.
Request a consultationWho this is for
Carriers, regulators, and enterprises that depend on mobile identity.
Problem
Internet identity often ignores the SIM and the signalling plane until a SIM-swap incident.

Definition
Telecom cybersecurity covers radio access, core networks, signalling (including SS7 and Diameter), subscriber databases, and the identity of SIMs and eSIMs.
Telecom Security
Why it matters
Mobile numbers remain recovery and authentication channels for banks, mail, and social platforms. Weakness in telecom identity becomes weakness in internet identity.
Telecom Security
Threat considerations
Signalling abuse, IMSI catchers, SIM swap, roaming fraud, and interconnect exposure are classic telecom threats. They are not solved by a stronger website password.
Telecom Security
5G and beyond
5G introduced improved subscriber identifier protection (for example SUCI) relative to legacy IMSI exposure. Newer generations change the threat surface; they do not retire SIM-swap or social-engineering risks.

Where this meets Keyra
Keyra's government and consultation surfaces describe carrier-scale authentication and telecommunications identity. Admin telecom-trust systems are not public docs. This page stays conceptual and precise.
Questions
What people ask first.
Plain answers. No product claims that have not been published elsewhere on Keyra.ie.
Is SS7 still relevant?
Legacy interconnect and roaming still make signalling security relevant even as 5G cores deploy. Exact exposure depends on the operator and interconnect policy.
Does a mobile network authenticate the human?
The network authenticates the subscriber module (SIM/eSIM) to the network. Binding that to a legal person is a separate identity problem.
