The challenge in the telco market is often to protect against highly-distributed denial of service (DDoS) attacks that can easily cripple a network. Solutions must be deployed that can protect against volumetric attacks like DDoS Secondly, telco organisations  need to be able to perform in-depth traffic analysis in order to protect against low signal attacks. This combination of performance and intelligence is a challenge for any protocol. By implementing purpose-built DNS security systems with adaptive countermeasures to ensure service continuity and data confidentiality, mobile operators can efficiently protect their DNS services.
