As a result of globalization, companies are striving to reach out to their
customers, suppliers and partners thus extending their enterprise to provide access to critical information and offer their services upon whom their business is dependent. The bedrock of far reaching enterprise is IP network. Researchers have developed core network technology like MPLS with promising features of flexibility, scalability and security to enable enterprises to extend their businesses and transact successfully. As a result, MPLS is widely used in supporting applications like data, voice and video on the internet. It has been highly competitive from its predecessors Frame relay and ATM in terms of providing supports services. Notwithstanding its attributes, there are vulnerabilities and risks associated with MPLS. Recent papers and research reports have highlighted such
issues. This paper represents a further contribution in identifying MPLS vulnerabilities and risks. In addition to discussing conventional approach of mitigating those risks, the paper also proposes IPSEC over MPLS VPN and its benefit over conventional approach.
