Telecom Sector Security

The Telecom sector has witnessed huge growth especially in emerging economies of Asia, Africa and South America. This has resulted in rapid expansion of the network, addition of value-added services, and resultant increase in complexity of the entire setup. Often, security can get overlooked or kept on the backburner in the rush to increase market share and reduce costs. However, cyber-criminals don’t care for such economic realities, and they have begun to increasingly target telecom infrastructure, especially as it becomes IP-based with the arrival of LTE.


This combined with increasing regulations towards telecom security have created quite a challenge that telcos are seeking to address. Our experience with telcos have revealed that while there are a variety of security issues – some of these are solvable, while others will remain known risks till cost-feasible measures can be found to address them.


Telecom Security Threats:

Major threats to Telecom Security usually fall into the following categories:

  1. Phone Fraud – Toll Fraud, Cramming, Telemarketing fraud, War dialing and so on
  2. Theft - Data theft, network abuse, illegal data interception, unauthorized data modification (in billing or routing based processes)
  3. Malware - Viruses, trojan horse
  4. Spam – Sending Spam messages via SMS, MMS
  5. Denial of Service attacks - Request flooding, DoS attacks against network infrastructure.
  6. Data leakage – Penetrating billing and CRM systems to extract customer data
