The demise of the legacy phone network (PSTN) has been a topic of discussion in many forums. For example, I recently came across a blog titled Heralding the death of the PSTN.
VOIP deployments are gaining momentum at the expense of the plain old telephone service and we are witnessing the emergence of IPTV as a viable alternative for delivering video compared to the legacy cable and satellite media. These are highlighting a trend where IP is becoming the de-facto communication protocol for not only data but for voice and video as well.
Service providers are faced with the challenges of building a single network to offer multiple services such as VOIP. The service infrastructures for delivering voice and video have become targets of attack just like publicly accessible web servers. If a VOIP server is compromised or comes under a DOS attack, the subscriber will not be able to get a call through. Similarly in an IPTV deployment, an attack on the video server would result in the subscriber being unable to change channels – which undoubtedly would be quite frustrating!
In order to roll out successful IP based voice and video services, it is vital to incorporate high-performance security mechanisms into your network design especially since these converged services are not too far in the future.
Is your security gear ready to turn on the lights for VOIP and IPTV?
