LAN is generally most common & very useful network in every organization. In today's world maintaining the security of information is a must. In addition to discussing conventionalĪpproach of mitigating those risks, the paper also proposes IPSEC over MPLS VPN and its benefit over conventional approach. This paper represents a further contribution in identifying MPLS vulnerabilities and risks. Recent papers and research reports have highlighted such issues. There are vulnerabilities and risks associated with MPLS. It has been highlyĬompetitive from its predecessors Frame relay and ATM in terms of providing supports services. Researchers have developed core network technology like MPLS with promisingįeatures of flexibility, scalability and security to enable enterprises to extend their businesses and transact successfully.Īs a result, MPLS is widely used in supporting applications like data, voice and video on the internet. The bedrock of far reaching enterprise is IP network. Their enterprise to provide access to critical information and offer their services upon whom their business is dependent. It also discusses mitigation strategies that can be implemented by service providers and MPLS VPN customers.Īs a result of globalization, companies are striving to reach out to their customers, suppliers and partners thus extending This paper describes three classes of exploits on MPLS VPNs: route modification, traffic injection and denial-of-service attacks. Because BGP is crucial to implementing MPLS VPNs, special attention is directed at the protocol and its multiprotocol extensions. This paper analyzes the principal security threats to MPLS virtual private networks (VPNs). The technology is also attractive to service providers because it enables them to flexibly provision resources for a variety of classes of service and applications with excellent quality of service at low cost. It provides corporate and government customers with flexible, inexpensive “autobahns” that seamlessly connect multiple, geographically-dispersed sites, enabling voice, video, data and other high-bandwidth applications. Multiprotocol label switching (MPLS) based virtual private networking is one of the fastest-growing network technologies. The purpose of creating such a WAN is to allow the resources of a company to be remotely accessed. The purpose of this paper is to serve as a basis when creating an enterprise WAN which connects sites and users together using VPN technology. In order to decide what VPN solutions to choose for different parts of the enterprise infrastructure, the chosen solution should be the one that best meets the requirements of the enterprise. These categories often overlap each other. VPNs can be categorized as Secure or Trusted VPNs, Client-based or Web-based VPNs, Customer Edge-based or Provider Edge-based VPNs, or Outsourced or In-house VPNs.

There are many different VPN solutions out there, and just deciding which one to choose can be difficult since they all have advantages and disadvantages. This paper discusses such protection mechanisms based on filtering and cryptographicĪ virtual private network (VPN) can be defined as a way to provide secure communication between members of a group through use of public telecommunication infrastructure, maintaining privacy through the use of a tunneling protocol and security procedures. Provide an uninterrupted VPN service, a protection mechanism is to be added at the edge Malicious traffic enters into the Internet only through the edge network.

It also hinders the services provided by the Threat to enterprises operating over the Internet. Protection against Denial of Service (DoS) attack. IPSec protocol provides various security features but it does not provide any IP Security (IPSec) VPN provides confidentiality, integrity and availability through tunnellingĪnd encryption. It helps in constructing a geographically dispersed LAN that can securelyĬommunicate data using the Internet as the backbone communication network. Network (VPN) is a popular service to logically construct private network using the existing It has become a necessity to protect data through the Internet. As internet is open to public, the seeking for sensitive data by the attacker

Internet Protocol (IP) examines only the packet header to forward the packet but it does notĮxamine the data in it.
