SMART IDS: An Enhanced Network Security Model in IP-MPLS Based Virtual Private Network

Contemporary, global cyber terrorism via the internet have changed the landscape of security implementations in cooperate organizations. This paper discusses analyses and develops novel security architecture for secure transactions in Virtual Private Network (VPN) environments. Open standard VPN has been in use for a long time without addressing the security holes in VPN wired and wireless networks. Several proposals have been made in the context of enhanced intrusion detection system (IDS) and reliable VPN design which is presumed to provide an in depth solution that guarantees secure operations of the enterprise network. However, this work presents SMART Network Security System (SNSS) which is shown to be very reliable and supports multiple functionalities for both LAN and WLAN VPN setups. The SNSS models have a Multilayer Access Point Intrusion Detection System (MAPIDS) sensor for monitoring traffic and network behavior. Also, cryptographic security features viz: authentication, confidentiality, integrity and auto-replay characterize the model. As such, the system is developed for multiple integration and cost effectiveness in its deployment. Performance parameters such IP VPN tunnel delay, packet traffic throughput effects, and ping response times (ICMP) were analyzed. The modeling and simulation was executed with OPNET IT Guru application while generating our validation plots in the network model.
