Carrier-class VPN to cloud evolution

Abstract

This paper analyzes the technology of cloud computing and the challenges that occur when connection is established through the Internet and public devices. Devices used for connection to the secured network very often don’t meet the security levels of the network that they connect to. To ensure that the connection is secured even from a public device and through the Internet major role is played by older technology, VPN. Therefore, we will present the security measures taken to secure the remote connection and the challenges faced to meet such a level, benefits, reliability, performance and latency of an enterprise network. These issues must be solved appropriately to ensure the confidentiality and integrity of data and information, as well as overall corporate network security. Obtained analysis in this work also presents the evolution of the cloud related to VPN, addressing the general security risks associated when using devices via VPN to access to an enterprise internal network. Furthermore, we analyze SSL VPN security risks in this context.
