Innovation fostering the Growth of NGNs Smart devices –Television –Computers –PDA –Mobile Phone ( Single device to provide an end-to-end, seamlessly secure access) Application Simplicity –Preference of single, simple and secure interface to access applications or content –Ubiquitous interface - web browser Flexible Infrastructure Because of these areas of evolution, today’s NGNs are defined more by the services they support than by traditional demarcation of Physical Infrastructure.
The Emergence of NGNs The communication network operating two years ago are father’s telecommunication Network. NGNs are teenager’s Network. No longer consumer and business accept the limitation of single-use device or network. Both individuals and Business want the ability to communicate, work and be entertained over any device, any time, anywhere. The demand of these services coupled with innovation in technology is advancing traditional telecommunication far outside its original purpose.
6 The Complexity of Today’s Network Changes Brought in IT Large network as backbone for connectivity across the country Multiple Service providers for providing links – BSNL, MTNL, Reliance, TATA, Rail Tel Multiple Technologies to support network infrastructure CDMA, VSAT, DSL Multiple Applications Router Internet Intranet Unmanaged Device New PC Internet Perimeter Network Branch Offices Remote Workers Home Users Unmanaged Devices Router Branch Offices Desktops Laptops Servers Extranet Servers Router Network Infrastructure Unmanaged Devices Perimeter Network Servers Trends shaping the future Ubiquitous computing, networking and mobility Embedded Computing Security IPv6 VoIP
Challenges for Network Operator Business challenges include new Pricing Structure, new relationship and new competitors. Technical challenges include migrating and integrating with new advances in technologies from fibre optics, installation of Wi-Fi support. Developing a comprehensive Security Policy and architecture in support of NGN services.
To Reap Benefits To reap benefits of NGN, the operator must address –Technology –Risk –Security –Efficiency
NGN Architecture Identify Layer Compromises of end users owned by a telecom or a third-party service provider accessing services using devices like PC, PDA or mobile phone, to connect to the Internet Service Layer Hosts service applications and provides a framework for the creation of customer-focused services provided by either operator or a third-party service provider Network Layer Performs service execution, service management, network management and media control functions Connects with the backbone network Internet Third-Party Application Untrusted Web Tier Service Provider Application Service Delivery Platform (Service Provider ) Service Delivery Platform Common Framework Backbone Network Partly Trusted
10 Growing Concern Computing Technology has turned against us Exponential growth in security incidents –Pentagon, US in 2007 –Estonia in April 2007 –Computer System of German Chancellory and three Ministries –Highly classified computer network in New Zealand & Australia Complex and target oriented software Common computing technologies and systems Constant probing and mapping of network systems

Trends of Incidents Sophisticated attacks –Attackers are refining their methods and consolidating assets to create global networks that support coordinated criminal activity Rise of Cyber Spying and Targeted attacks –Mapping of network, probing for weakness/vulnerabilities Malware propagation through Website intrusion –Large scale SQL Injection attacks like Asprox Botnet Malware propagation through Spam on the rise –Storm worm, which is one of the most notorious malware programs seen during 2007-08, circulates through spam
Trends of Incidents Phishing –Increase in cases of fast-flux phishing and rock-phish –Domain name phishing and Registrar impersonation Crimeware –Targeting personal information for financial frauds Information Stealing through social networking sites Rise in Attack toolkits –Toolkits like Mpack and Neospolit can launch exploits for browser and client-side vulnerabilities against users who visit a malicious or compromised sites

Security of Information Assets Security of information & information assets is becoming a major area of concern With every new application, newer vulnerabilities crop up, posing immense challenges to those who are mandated to protect the IT assets Coupled with this host of legal requirements and international business compliance requirements on data protection and privacy place a huge demand on IT/ITES/BPO service organizations We need to generate ‘Trust & Confidence’
Model Followed Internationally Internationally, the general approach has been to have legal drivers supported by suitable verification mechanism. For example, in USA Legal drivers have been –SOX –HIPPA –GLBA –FISMA etc. In Europe, the legal driver has been the “Data Protection Act” supported by ISO27001 ISMS.
