Control for telecoms

Path governance for carrier networks.

Telecommunications infrastructure carries the data of entire nations. When management planes are compromised, attackers do not just reach one organisation. They reach every organisation that relies on the network.

  • Vendor access risks
  • Signalling exploitation

The challenge

Carrier networks face persistent, sophisticated threats.

Telecommunications networks are national infrastructure. If the management plane is reachable from the data plane, every subscriber and every organisation relying on that network is exposed.

  1. Management and configuration data held in secured Firevault Bunkers.

  2. Vendor maintenance sessions require sign-off from both the vendor team and internal network security.

  3. Automated compliance logging that can help support Ofcom security requirements and NIS2 Article 21 outcomes.

Challenge 2

Vendor access risks.

Equipment vendors require ongoing access for maintenance, creating persistent pathways that attackers exploit through supply chain compromise.

Challenge 3

Signalling exploitation.

SS7 and Diameter signalling vulnerabilities allow interception and redirection of subscriber communications across interconnected networks.

The scenario

Scenario: core network management compromise.

Fourteen vendor access paths looked solid on paper. Mapped for real reachability, each could be traversed with enough privilege escalation. Step through it, or play it through.

Step 1 of 2

The attack path

An advanced persistent threat group compromises a vendor remote access portal used for routine maintenance on mobile core equipment. Over six weeks, they escalate privileges from the vendor management VLAN into the packet core.

They gain access to subscriber location data and call routing tables, and redirect traffic for targeted individuals through compromised nodes for interception.

Where each module sits

Where each Control module is deployed across BSS, OSS, the core network and the edge.

Telecoms operators run business systems, an OSS that manages the network, a packet core and signalling, and RAN and edge equipment that reaches the subscriber.

Ofcom and NIS2 evidence

Automated compliance logging that can help support Ofcom security requirements and NIS2 Article 21 outcomes.

Telecoms

Out-of-band management

Dedicated cellular connectivity provides control plane access independent of the carrier network itself.

Telecoms

Tamper-evident audit trail

Every vendor session, configuration change and access authorisation is recorded.

Telecoms

Verified core configuration baselines

Verified baselines of core network configuration support restoration of control-plane state.

Adoption guide

From first boundary to routine operation.

Four steps, piloted on one site before it extends across the estate.

  1. 1

    Network path audit

    Map every vendor, management and signalling path into your core network infrastructure.

  2. 2

    Zone architecture design

    Design physically separated network zones for management, signalling, subscriber data and vendor access.

  3. 3

    Controlled pilot

    Deploy in a non-production network segment with full vendor access governance and multi-party authorisation.

  4. 4

    Core network deployment

    Full deployment across core network infrastructure, with verified configuration baselines.

Questions

What teams ask first

Paths open as named, time-bound events with the right approval, so planned work runs through the windows your NOC already schedules.

Yes. Vendor paths open for the window of work, with sign-off from the vendor team and internal network security, and close again afterwards.

It governs the management and vendor paths around signalling rather than the protocols themselves, keeping the management plane on a separate, disconnected network.

Zones can be severed in milliseconds over an out-of-band command, and verified configuration baselines support restoration of control-plane state.
